The 2012 Propeller SmorgasBoard is a collection of 23 open source propeller PCB designs, complete with source files, gerbers etc.
The designs have been combined into a large "letter" sized, tab routed, PCB panel. It's available from Gadget Gangster (http://www.gadgetgangster.com/find-a-project/56?projectnum=404) and PropellerPowered (http://propellerpowered.com/shop/?page_id=549) for less than $1 per design.

There is now a Wiki for the designs on the 2012 Smorgasboard, please see here

*** UPDATE August 17th
Now available from PropellerPowered (http://propellerpowered.com/shop/?page_id=549). Thanks, OBC!
--
*** UPDATE JUNE 4th
Now shipping from Gadget Gangster.
Smorgasboard Wiki public release.

*** UPDATE APRIL 12th
Production boards have shipped from the fab for delivery week commencing April 16.
My apologies for missing UPEW by the narrowest of margins

*** UPDATE MARCH 15th -
Production boards have been ordered for delivery by end of March, in time for UPEW
Five of the designs have minor revisions.
Now I'm putting together some overall documentation, board selection table etc.

*** UPDATE JAN 23rd -
First small run of boards have been received and look great. See photos in post #91 (http://forums.parallax.com/showthread.php?135920-2012-Propeller-Community-OSHW-quot-SmorgasBoard-quot-***-PHOTOS!!-***&p=1068253&viewfull=1#post1068253)
Now checking for any major faults, then its into full production.

*** UPDATE DEC 9th - now 22 designs
Cluso's tiny Memblade (1x1") is now onboard
Added a tiny Prop to PIC8 (eg PIC12F675) format adapter, .66 x .44 ", to fill in a void
The panel is with the fab but there have been some file issues. Hope to resolve today and see proto panels just before Christmas.

*** UPDATE DEC 1st - we've hit 20 designs!
Ariba's PropinoPP is included
my Ninja Star fits (just)
Cluso's tiny FT232 adapter is on board
updated Layout (rev E - final, letter sized panel, with aligned boards for easy division)
see new spreadsheet attachment for list of included boards and their size

*** UPDATE NOV 23rd - 16 designs
Martin Hodge's ASC is now on board! Great news for those with arduino shields
Roadster's PropGFX implementation is now on board!
WBA's M44D40+ adapter is now on board!
we're getting close to full now. Please get in contact if you're still undecided and I'll see if it would fit.
Layout revD update later today hopefully. Off to the fab early next week

*** UPDATE NOV 22nd
Hanno's Dancebot and Bill/Sapeiha/Brian/Hanno's IO Dreamkit are now on the panel!
I have dropped the parallax products off to make room, and besides these are great value fully assembled.
There is still some space, and the panel can be enlarged slightly out to the red line. If you have something to share, please contact me.

*** ORIGINAL POST:-
OldBitCollector just got a great response (http://forums.parallax.com/showthread.php?135884-MIT-GNU-Tiny-form-factor-Propeller-layout-around) to his call for open source propeller hardware, with (including Parallax open source options) about 12 designs to choose from.

As one design doesn't fit all applications, I thought it might be interesting to make a tab routed "sampler" panel to showcase the various open source hardware options.

I'd be prepared to get these made at cost, and believe it would work out at about $1.00 per board (ie $19.95 for the panel), plus postage.

So, what do the design stakeholders think of this?

End users, would < $1.00 per very useful board appeal?

Let me know your thoughts...

Phil Pilgrim (PhiPi)
11-17-2011, 04:45 AM
Looks good, Tubular. I think a panel is a great idea! However, if people need to saw them apart themselves, the boards need to be arrayed such that each successive saw cut can go all the way across the panel without cutting into another board.

What if they are pre-routed with spars, like a model kit? I'd pay $20 for a panel, maybe $25, if it was easy to break apart and had good pads an solder mask.

If I read this correctly, is this a pcb 'panel'?

If so, YES, I'm interested too. Great idea.

And, if the boards are routed or otherwise easy to remove, that would be super. But I'd guess that adds a bit to the price of each panel.

Thanks for idea, and for so many interested in having one or more.

I'd guess OSHW means 'open source hardware'?

Tubular
11-17-2011, 05:25 AM
Thanks Pedward!

Here's the updated layout, with all the Propeller Platform modules in the same column.

I have added MacTuxLin's design, made it "binder book" compatible. The binder holes may also be used to route power and P30/P31 to the boards

Phil, I'm thinking tab routing like this http://www.sparkfun.com/products/10817

*Lots* happening behind the scenes, pedward, and its the weekend here which gives me a chance to push it through. Looked at all the gerbers so far last night. Contacted most of the design stakeholders. Plenty of positive sentiment about making this happen. There are some really nice boards on this panel.

There is still room for a little more on the panel, though we certainly have a quorum. Since its a smorgasboard it would be good to have something from Scandinavia. Where are you, Sapieha? Heater? Tor?

I'll post a kind of hybrid pic in a moment to show what its looking like so far.

I have to do some telit demos, but expect this to go to the fab mid next week.

Here's an "artist's impression" of the panel layout so far.

I might drop the Spinneret and Propstick USB, as these are far more useful fully built from parallax. I would still like to convey their availability as open source references somehow. For the quickstart I am thinking of doing a DIP version in the same footprint (smt components on back).

There is still room - the panel can grow wider if required.

What do you think so far?

Tubular
11-22-2011, 03:19 AM
Updated layout posted at the top

Exciting news - we now have Hanno's DanceBot, and Bill/Sapieha/Bryan/Hanno's IO Dreamkit on the panel!

There is still room - apart from the yellow spare squares, we can use up to the red line boundary if we need it, so if you have an open source prop master you would like to included, please send it through!

11-22-2011, 03:34 AM
Tubular,

Thanks for doing this. Is a panel that size going to be a problem to ship? Would having a place to cut it down the center help with shipping costs?

I hope you'll put me down for two.

Tubular
11-22-2011, 03:41 AM
That's a good point, Duane. There are a couple of extra boards I'm hoping we can add, and when I shuffle I'll try and leave some kind of fracture line in the middle.

I did look briefly at smaller size envelopes at this end, and decided "letter" size was as good as anything. But the US is probably different - is there a limit on what a "small letter" size is allowed?

jazzed
11-22-2011, 03:53 AM
@Tubular,

I have another design that would fit nicely in the "spare" area just above the SpinSocket Flash module.
It's a SpinSocket board with 8 synchronous SRAM chips on it.

I'll send you a gerber tomorrow.

Is the Propeller ASC by Martin Hodge an open design? I've recognized the thread Arduino presents and see the ASC as a great solution for competing with it.

Aside:

It's curious that the Arduino is so popular, given the 8bit processor and relatively less power than the Propeller. However, I do see that the Arduino has a few things going for it:


Standardized board footprint
Standardized IDE and a basic builtin API to talk to the hardware
Large 3rd party support base


The things I see that the Propeller is lacking to compete readily with the Arduino:


While the Prop has a ton of software peripherals, they are not library items of the IDE, it can be very difficult to find the "correct" OBJ for doing something.
The Prop IDE is very basic and lacks version control and a proper OBJ library
The Prop seems to have a bunch of different layouts, and the Quickstart board has introduced yet another


While Eclipse will solve some, or a good many, software issues with the Prop 2, that chip really raises the bar, and demand, of the developer. The Prop 1 really needs a bulletproof IDE that integrates a lot of this to make it run head to head with the Arduino.

The hardware layout issue could be resolved by Parallax endorsing a specific "standard" layout. They seem to be all over the place when you look at the online store. Sure, they are all great designs, but the fragmentation makes it very difficult for new users to get started.

While the Quickstart is neat, I feel it was designed more for price than development. The DIL header is not very friendly for getting I/O off the card.

The Gadget Gangster Propeller Platform seems to be a leader in the board layout choices, but it ignores the wealth of Arduino shields and compatible boards that already exist.

While the Arduino and Propeller may be the Chevy vs Ford debate, it's a lot easier to co-opt the Arduino's strengths and offer a superior, perhaps easier to develop for, silicon.

BTW, the name is Perry.

While I can't do anything about the different layouts except contribute given an opportunity ... I do have some influence with software. I have discussed the IDE library items problem you mention with Parallax in some meetings, and we have infrastructure in Propeller GCC to make it possible.

I'm curious about source control. Obviously an "enterprise" solution like Eclipse or NetBeans offers integrated source control, so that's relatively easy. However, do you see a need for source control in a "simple" hobbyist IDE? To keep from polluting this thread, could you answer that in a private message? Thanks.

For real? $12.00 bucks per panel?? Sheesh, even the poor peoples can get one of these,
Just gotta figure out how to populate the thing with all the parts...

In the theater of my mind, I walked thru cutting up (depanelized) most of your latest version of the layout,
I think the lower right corner is the only trouble spot,
Could you reorintate the "puppy board" and switch it places with the "spare spot" just to its right?
It looked like it would fit, and then a band saw could do all the cuts with no backing up...

Anyway, two thumbs up for the whole SmorgasBoard project..:thumb::thumb:

Tubular
11-22-2011, 05:17 AM
Jazzed, that space is yours. Look forward to another neat design!


Perry, many of us are putting our efforts behind the Propeller Platform header format, as Parallax has requested (http://forums.parallax.com/showthread.php?131530-Parallax-Semiconductor-backs-Gadget-Gangster-as-a-standard-platform). The QuickStart is a great introduction for the prop, but I don't think it's intended for everyone to build a sprawling platform on top of. As time goes on there will be more and more propeller platform plug in boards, QuickStart can remain Parallax Semiconductor's evaluation platform without being too polluted by our rampant designing.

Having said that I for one would still really like to see a smaller standard for the Propeller platform - something perhaps 1.2~1.35" wide. Max72's design on the Smorgasboard fits this category, and I look forward to having a good look at it once it comes back from the fab. One advantage of the PP format being wider is that arduino shields can be 'encapsulated' within the PP headers. I have a design that does this but have my hands full getting this panel away first. We might do a second panel for PP modules and plugins when we have enough open source content.

As for the software, its not as bad as it first appears, and there's plenty that can (and is) be done to consolidate the software nicely.

Thanks Tommy

The type of "tab routing" we are using means you don't need a saw. There is a 2mm "moat" around the panels, except for small (~4mm) "bridges" every inch so to tie the boards together. The bridges even have ~ 8 little holes in them, and this makes it easy to simply snap the boards apart. I'll try and find a photo of what I mean, but you don't need a bandsaw, just a file or sanding block at most. Here's one example, (http://pcbpro.info/images/pcb_tab_route.jpg) kinda close to what I mean... though every pcb company does it slightly differently.

pedward
11-22-2011, 05:46 AM
Martin, don't feel pressured into doing something. I was merely asking because I didn't see anything pointing one way or another.

Tubular's comments about the Arduino form factor fitting within the PP footprint are valid and having a dual set of populated headers would be a fine way to coax those firmly entrenched Arduinites out of the crowd.

Agreed,Cluso. Leaving it til later because it's not hard to place. I'm giving priority to designs with a P8x32A on them but a couple of accessory boards should squeeze on towards the end. Still waiting to hear about a couple of designs, then we'll see what space is left over.

I wonder if it would make sense to not just copy the open layouts, but make some changes / improvements to the designs (this is the main purpose of open source layouts).

For example:
- The Quickstart Board misses a pullup on the P30 line which causes some trouble with serial communication. This resistor really should be added. Other ideas: On/Off switch, capacitive sensors.

- The GG PropellerPlatform USB has the SD card on P0..P3 which conflicts with fast external memory designs. I would moving it to P8..P11 or just bring the SD card pins to 4 holes which can be wired to the pins you want.

Andy,

I like that idea, at least run any suggested changes by the original designers for approval. My only concerns about this are:

1) feature creep - we can do this, this and this and wow, then it will really be something.
2) something gets broken and we end up with a bunch of dysfunctional cards on the "Smorgasboard"
3) it turns into an on-going, never ending debate of what should get added

As the designs exist now, I do believe tehy are all functional and have been through at least one "PRODUCTION" run.

Just my 2 bits.

Hi Andy,

I know it's tempting, but this panel is celebrating the diversity of open source propeller designs, warts and all.

The benefit of open source means end users can grab the most suitable design, make the changes that suit them, and have something they are really happy with, despite minimal effort. The mods you mention are part of a huge spectrum of possible improvements, eg reserving P0 and P1 for USB, P0-8 for fast bus, having mounting holes or not (then PP holes vs GG holes vs other holes), socketed crystal or not, QFN vs QFP. In the end only the end user can specify what they really need, and its going to be easier than ever to get exactly what they want.

I also think changing pins, while having benefits from a bus point of view, would confuse lots of end users searching the forum.

Now Andy, surely you must have something to contribute (complete with p30 pullup!) - what about those puzzle boards you did?

Now Andy, surely you must have something to contribute (complete with p30 pullup!) - what about those puzzle boards you did?


The Prop-Puzzle baseboard has not much value without the many accessory boards that belong to it, and it's a really old (single sided) design.
I have more interesting newer designs. A prototype PCB of the newest comes next Friday, this would be a good candidate It has basically Arduino, PropellerPlatform and 10pin-standard headers together with some Extras. But I need to test it first - When is the deadline ?

My boards usually have no pullup at P30, but they also not have this tri-state buffer that makes the pullup necessary. A good example of how adding a lot of components to make a circuit better also adds more possibility for mistakes.

After much wrestling I have layout Rev E which is "US letter" sized, minus .015" spare space!

Final layout is attached to the first post.

Off to the fab today or Monday for the first run.

Landed cost looks like being around $14 per panel (70c per board!) , some localized shipping and handling on top of that.

OBC

The boards will be "tab routed", which means they are "mostly separated by a 2mm routed gap", but connected by little bridges. It is easy to snap the bridges because they are only ~ 1/8" long and have weakening holes in them.

This works really well, the boards stay connected during shipping. You don't need tools to snap them, just break them apart with your hands. You just need to rub a sanding block or file over afterwards to clean up the tab (optional)

Here's a close up pic of a small set of tab routed boards. See the broken tabs around the outside? It only takes a couple of sweeps of the sanding block to remove these. These are tiny boards so the tabs look big. Normally there is a ~4mm bridge every 40mm or so (about a 10% duty cycle!) . The router bit width and tiny tab hole diameters vary from one fab house to another slightly.

Thanks OBC

When I rearranged the panel I made it so it should be easy to break it into half, or into quarters, to "fold over", so hopefully this does fit standard envelopes.

The panel is 1mm wider than Letter size, and slightly shorter (lengthwise). So if it doesn't fit, I'd blame my Ninja board and Cluso's Memblade :)

The job is with the fab now, it will take a while to straighten out and panelize and cross check, but its all happening

I'm just curious on the progress of the "SmorgasBoard". Thanks!

Well, it is progressing. I sent files + payment to the fab last weekend, but they had some issues with the files that have (just) been sorted out. I don't think they are used to 22 designs from so many different packages, to be honest.

So I expect to receive a proto run of panels just before Christmas (will certainly post pics etc, and build and test some of them), and main production early in the new year.

The good news is that in the meantime, with a bit of rearranging, 2 more small boards have been added onto the panel.

Ale,

There are a few - Cluso's MemBlade has something, my Underbelly and PP LCI have C3-style memory blocks under them that can have 64~96kB sram, and Jazzed's SpinSocket does as you point out (there is one with flash and one with Sram)

I suspect there may be others. Right now I'm focussed on getting the panel manufacture underway but I will soon round up the features and philosophies behind the various designs.

12-09-2011, 01:51 PM
The CpuBlade and MemBlade are both on the panel. They stack to form a RamBlade3 w 512KB sram and microSD. The Ft232 can be used to add USB and 5v power ( need 1jumper cable for power). More info on my website and that points to the forum threads for more info.

Hi all:

Attached is a document package for the SpinSocket-Flash boards.
It contains schematic, parts-list, and top/bottom assembly drawings.

Parts kits are available for anyone who wants to assemble and use the boards.

Parts kits for 4MB SpinSocket-Flash are $29 each (does not include PCB).
Functional Rev A1 PCBs are available from me to USA customers for $5 each.
Prices do not reflect taxes or shipping costs. Send me PM for more information.

http://forums.parallax.com/attachment.php?attachmentid=88710&d=1326929366

What is SpinSocket-Flash ?

The SpinSocket Flash boards allow 4MB of instant on Flash code space
with cheap and commonly available Winbond W25Q16 devices. Other
devices such as W25Q64 can be used for 32MB if you can find them.

When using optional Quad-SPI Flash for executing code, 18 user
IO pins are free for any purpose and serial port pins are also available.
This means huge programs (no more straight jackets), Spin speed,
and lots of user pins in a 1.22 square inch single board package.

SpinSocket-Flash relies on the Parallax PropPlug for programming.


Parts List Assembly Options:

1. Standard parts list shows using a 3.3VDC regulator for 4.2V to 15V DC Vin.
It is possible to use the board with 2 AA batteries or a single 3.0V coin cell
by using L1 and VBST instead of 3.3VR. The battery configuration offers
only limited current however at 100mA or less, and the VBST device will not
limit voltage down, as it is only a boost device.

2. U1 and U2 are designed for Quad-SPI flash devices and are supported by
GCC XMMC mode. This is a very fast code execute configuration.

The Quad-SPI Flash chip footprints U1 and U2 are pin compatible with SPI SRAM.
It is also possible to use a SPI-SRAM in U1 and Quad-SPI Flash in U2 - I tested
this last year, but do not have a Propeller GCC driver for it yet.

It is also possible to use 2 each MCP3202 ADCs in U1 and U2 for 4 SPI-ADC
channels. Some rework will be required, but it is minimal.


I'll post documentation for the SpinSocket-SRAM module later.

Cheers,
--Steve

Hey Jazzed nice work on the documentation pack. Cluso, glad it arrived safely.

I'm *really* happy with how it worked out, especially the overlay (silk) and alignment. Only minor issue so far is with the tabs encroaching more than absolutely necessary on the smaller pcbs...

As you might expect, I spent a lot of time soldering and checking things over the weekend. All good so far.

News on the M44D40+ Board by WBA (http://forums.parallax.com/showthread.php?131867) on this panel:

Well, I am an idiot. From the photo of the panel I realized that my board didn't look quite right. After some digging, I discovered I sent an incorrect file package to Tubular. What does that mean you ask? Well, it means that my board on this version as the following two issues:
1) The EEPROM does not have a connection to ground. A jumper wire would need to be added.
2) There is no programming header on this version meaning the EEPROM would need to be programmed in another manner.

I have sent correct files to Tubular and the next spin of the panel will include matching files to my released version. For anyone that purchases one of these first run panels and wants a released version (http://forums.parallax.com/showthread.php?131867) of my board, I will mail one to you.

These boards all look great. Many thanks to tubular (Lachlan) for putting this together, and to all the contributors for sharing their works.

One thing I noticed is the many different footprints for the mini-USB (smt) connector. May I suggest a standard - I searched for the smallest footprint and found this at DigiKey (I try to get most of my parts from the one supplier)
http://search.digikey.com/us/en/products/UX60SC-MB-5ST(80)/H11671CT-ND/2004580 (preferred but out of stock when I ordered)
http://search.digikey.com/us/en/products/UX60SA-MB-5ST(80)/H11921CT-ND/2606388 (alternative - same short footprint)
Does anyone have anything better???

I extend my pcb footprints to make hand soldering easier.

I also extend the microSD pcb footprints which is BTW
http://search.digikey.com/us/en/products/DM3D-SF/HR1941CT-ND/1786515

I noted a few are using the power connector with normal pins requiring either slots or large holes. Here is a smaller pin version
http://search.digikey.com/scripts/DkSearch/dksus.dll?WT.z_header=search_go&lang=en&site=us&keywords=CP-102A-ND

BTW I am no longer putting these DC power connectors on my boards, preferring to use the miniUSB to bring in 5V power. Supplies are readily available as are the USB to miniUSB cables. Many people have these already for phones, etc.

Another note to add for this set. The ASC board version is one without the bypass pads on the back. Since anyone crazy enough to try to build one (besides me) would be able to use the resistor pads for either current limiting resistors or solder jumpers as they build it.

I like those mini USB's you found. I have been heading towards Micro USB because that's what I use with my phones etc, plus they fit within 5mm or so of the board edge. However an extra 2mm to gain a more robust connector in the Mini B is worthwhile IMHO.

01-24-2012, 01:36 PM
First of all thanks for the kind words. Appreciation from this forum is an honour.

Please find attached a part list for my USB board. The most challenging part to hand solder is the FT232. Many key components are the same suggested by Cluso (SD, barrel plug, USB plug).
For sure silkscreen is to be fixed, and maybe it would be nice to have a LED or two for power on. The switch is not really accessible. Anyway it works and in the spirit of sharing a starting point for customization there is room for improvements.

Linking to Cluso's post I wonder if it would be the case to create a kind of preferred/working/useful components list.
I used the same uSD used in Gadget Gangster's board, but other parts derive from independent web search. Many others probably spent some time looking for similar solutions, after all the basic bricks in a prop board are the same.
Moreover the eeprom I used is discontinued now, and a TSSOP eeprom is widely used, so a "current" list would help a lot.
We could create a page on this forum or on wikispaces to have a starting point list.
This is by no means a suggestion to create a standard, but simply share components that are already used and are working, and maybe with a web search are buried in hundreds of results.

Tubular: I have tested it - I have it on my FT232 board and use that all the time now. I find it very robust because the shell solders well to the pcb. If concerned, put a pair of vias in the mounting pads and a small pad underneath. Anyway, you should have one by Friday.

If any of the board designers want to send me the BOM for your board, I'll try and build BOM kits on Digi-Key's site so parts ordering would be easier to get for those of us that don't "carry inventory". Once built, if Element-14, Farnell, RS, Mouser or any other places have BOM kits, we can transfer them to those sites.

If GG was planning on doing anything like this, then forget I mentioned it.

You can send your BOM to: mindrobots@ that google e-mail place (gmail.com) - if you do so, prepare to be pestered so I don't mess these up or if we need to substitute parts, etc.

Awesome mindrobots. Let me help you with that, I already have some BoM lists, and can certainly look after the Aust/NZ board boms.

I've used the Mouser kit facility but not the Digikey. I'll ask my E14 rep what they have that may do the same job.

I received the Mouser kit Jonnymac put up for his CanBus project a few months ago. One really nice feature is that there is a user comment that actually gets printed on the bags that turn up from Mouser. So you could put a comment like "TSSOP EEPROM for UND3RB3LLY pcb" and it's very clear what the part is for when building the kit (now or when you're scratching your head 2 years hence).

Hi Yoda

I just received my two sets of boards.

They're beautiful!

It's been a lot of fun to look them over.

I've recently started using DipTrace to make a few boards and these PCB are a great way for me to see how to design a Propeller board.

Earlier this evening I was trying to think of a small Propeller board to use with a GPS logger I'm going to build. I thought I'd likely use one of Tubular's Und3rb3lly boards. I still might use the Underbelly, but now I have lots of options to choose from.

Thank you to all those willing to share your Propeller designs.

I'm looking forward to seeing those BOMs. I know I'll want to populate a lot of these boards.

This is very exciting.

If any of you are thinking of learning to design PCBs, you ought to buy a set of these boards. There are lots of great examples of how to make a Propeller circuit board.

Thank you Tubular for putting these all together.

Thank you Jeff and GG for being willing to take care of shipping the boards (mine also arrived safe and sound).

Tubular (Lachlan) did a great job in putting all these boards together. I think we were all quite happy to contribute to this project.

There is a nice tiny PropPlug there of mine that can also provide 5V (from the USB) and has a combined LED for TX & RX. I have found this a great aid to see what is happening.
My other two boards (CpuBlade & MemBlade stacked will make a RamBlade3 that has 512KB 55ns SRAM and microSD)

I was hoping to claim the 3 smallest boards, but I was outdone by a Prop QFN board that I am struggling to see, let alone work out what it does. Whose board is it???

Tubular
06-03-2012, 01:12 PM
That small QFN board is one of 2 I created to fill in the space after all the other boards were fit.

It's really very user unfriendly. I think it has 6 easily accessible gpio, good enough for tv or monochrome VGA out, and a single eeprom on board. Comes out to a DIP8 header underneath. There are other I/O along the castellated edges, they can be soldered to a 0.05" pitch standard ribbon cable, and broken out to IDC from there...

I tried to reflow the Prop QFN but it went for a slide and soldered at a severe offset. Might have another go at it later once I'm better at reflowing.

There are some more details here (http://forums.parallax.com/showthread.php?136523-Small-Prop-to-PIC-adapter-(DIP8)&highlight=DIP8%2A)

My M44D40+ module (http://forums.parallax.com/showthread.php?131867) has it's own thread here, and I will throw the current DipTrace file onto it as well. I have no problem passing out the design to anyone.

After much stuffing around I decided a wikispace would be the most suitable for such a community project

The Smorgasboard Wiki is up and can be found here
http://smorgasboard.wikispaces.com/
(http://smorgasboard.wikispaces.com/)
A summary of the designs is here
http://smorgasboard.wikispaces.com/Designs

I have linked to the Smorgasboard wiki from the propeller wiki.

The wiki is not finished. I am having trouble uploading the source files (.Zip). The photos are a bit squashed in proportion and some are missing or outdated. If you are the author of a design feel free to update it with better photos, links, source files etc. We'll be adding BoM kits and links soon too. If you feel inspired to contribute to the wiki, don't hold back!

@ WBA the hotspot idea is a great one. I'm not sure whether it can be done easily with the wiki, but its worth checking out.
@ Jim I'm not sure either - I will email Hanno

Lol, thanks Jazzed. The (unofficial) slogan for tubular controls is "We've see the future, and it's totally tubular". People of a certain age (or nerdiness) get it just fine.

Hey got any photos of your assembled spinsockets? I'm sure they would look better on the wiki than the squashed images. The wiki seems to distort as you scale images up/down - the more scaling the more it distorts the aspect ratio. Not sure why - it may be overcompensating for viewing on a widescreen or something. I think the answer is to prescale everything prior to upload.

Tubular, can I get permissions to edit the wiki. I must say I had a look at my entry and went "yuck". The PuppySolo is just that, a Puppy I/O module that's footprint compatible with a whole range of other modules plus it's designed to hook-up to the real world in terms of LEDS, switches, motors, solenoids etc WITHOUT any extra components. The VP pins are not used here as they are normally connected to the motor power supply for source drivers, steppers etc. The current limited I/O is limited with 220R resistors so that you can hook them up straight to LEDs or transistors or even feed audio directly out with an optional capacitor. There are four current limited I/O with 10K pullups that can be used for switches or general-purpose use.

The Puppy modules are slim enough to be side to side stackable so that the 0.1" pitch connectors may be butted together without a gap.

93239
PuppySolo (microSD visible underneath PCB)


The basic features are:


Ready to connect to the real-world
Quad 6A 60V NCH MOSFET outputs
Quad current limit I/O with pullups
Eight current limit I/O (IO0..IO7)
Two direct I/O (P26,P27)
PropPlug header
Puppy I/O Module footprint - 32-pin 1.9" x 0.8"
Twin LED indicators
On-board regulator (max 6V in)
microSD socket

I've updated the Smorgasboard Wiki (http://smorgasboard.wikispaces.com/Design) again with those changes for Martin and Peter

Membership - I thought was kind of automatic, but perhaps it relies on email invitation, so I'm emailing all contributors an invite. If anyone else would like an invitation, just ask.

If you have lots more information about your design, and how it may be applied, feel free to create a page just for that design. I did a sample page for Martin's ASC while playing around with the wiki features.

Brian,

Thanks for dropping by. We can fix the name mix-up. Do you have a BOM for the IODreamkit? We'd like to gather together the BOM for all the boards and make the parts kits available through Mouser and other suppliers offering the BOM services. If you do, you can either post it here and we'll find it or email it to Tubular or myself.

Thanks!!

I think a lot of these boards are going to be built - this may become a collector's item!

You're very welcome, Brian. I;m sorry about the mistakes, I will correct them straight away - would you prefer your real name or Parts-man73 in the credits?

Also, do you know if there is a BoM for it? There is already one user asking, and I'd love to build it too. I emailed Hanno but he is traveling at the moment. If there is a bom I hope to create a Mouser kit for easy ordering.

thanks
Lachlan

Yeah the world suddenly shrinks doesn't it. I was editing the designs page just minutes before Jazzed was updating his Spinsocket photos.

I'll have a go tonight at creating some mouser kits for my own designs. I can do Phil's Propstick too, as I've built several and know it backwards. The mouser kits let you have your own "user description" for the parts, and I'd suggest we use the board name first, eg "PropStick - 5 MHz crystal " . The normal part details still appear on the mouser labels, this is just useful supplementary info that helps make kits easier to build

parts-man73
06-05-2012, 03:18 AM
maybe both... Brian Meade aka parts-man73

both of you please PM me your email addresses. I checked my mouser account, and was supprised to see it's still there and all my projects were still there.

Mouser has a great service, where you can store projects, including part numbers and quantities needed. When I was selling SpinStudio kits, I could simply select the project, multiply by the quantity I needed to make, and it dropped it into my shopping cart. I have the IODreamKit project that I can forward to you from mouser. Not all the parts are included in that. some of those small surface mount passives I just bought a reel off ebay, as you can normally find them for $10-20 for a whole reel of 5000

The crystal listed is wrong. I had a 5 mhz listed. The form factor is correct, but the speed is wrong for this board. I think at the time we comprimised with a 6 mhz crystal to run the board at 96 mhz, close to the rated speed of the fast ADC. 6 mhz was the best I could find in that size crystal. 6.25 would have been better.

oh also the fast ADC IC isn't available from mouser, so that's not in that project file either. It's a ADC08100 from National Semi

one other nitpicky thing about the wiki. There's no FET's. There is a ULN2803 for higher current output. - The parts you might have confused with FETs are Voltage Regulators

I hope we do get to that stage. There's still a bit to do on the hardware spec side before we're finally able to play.

I'm looking forward to actually building some or all of these designs - it'll be easier once we have the mouser parts kits up. Then it would be good to have some demo software (perhaps in both Spin and C) to show off come of the specific capabilities of each of the boards.

Don't forget there is also a PropPlug equivalent too, capable of powering (5V out) your project from the USB (within USB power specifications). It's smt but with increased solder pads to make hand soldering easier. Why not give smt a go!

Rayman: This gold flash is a process (ENIG) and doesn't require anything in regard to pcb design, so ExpressPCB is fine.

I thought ExpressPCB's production service might have supported ENIG, but it doesn't appear to be the case.

Rayman you can always pay the ~$60 to get the gerbers and go elsewhere, but it seems a shame to have to

The nice thing about the gold plating is the boards seem to "keep" well on the shelf.

We saw three of these boards go out in the last month...

I've issued a challenge tonight on the Propellerpowered forums. Addressing the scary subject of home SMD assembly. (A good October topic!)

I'm going to start by stocking two kits. (Need suggestions on which ones) and create step-by-step instructions to assemble them using only typical tools and materials which are available to the home hobbiest. We should start simple and use a couple of the smaller assemblies as it will help with stock of the kits. (You'll still need to get your SmorgasBoard, as the kits will only have the parts you need!) and build confidence as we move forward.

It's time that we removed the scary masks that seem to shadow SMD for DIY'ers. I'm proposing to help blaze a trail here using SmorgasBoard.

Suggestions on which two kits we should begin with are sought!

Jeff

Cluso99
10-05-2012, 06:32 AM
You need to select a pcb(s) that does not have a lot of smt in case you get it wrong. Also, the pcb needs to be laid out for hand soldering - this uses longer pads allowing you to swipe your soldering iron from the pin(s) out along the pad(s). This often will remove a solder bridge.

Next, you do not want to have a tight pitch smt part. Don't try an FT232RL first up - that rules out a number of pcbs unless you can bypass the FT232 easily.

PCBs using the TSSOP8 for the eeprom is a tight pitch, but pins 1-4 are joined together, so that is at least one side that does not matter.

I've found TSSOP8 is easier and faster to solder than SOIC8. A tiny dab of solder and flux works fine.

Cluso99
10-05-2012, 10:45 PM
Jazzed: I don't have any problems soldering them. But originally they were harder until I got used to soldering them, and others at 0.65mm pitch. I use a flux pencil which works brilliantly. And a temperature controlled fine tip soldering iron, and of course solder braid for just in case.

Tubular
10-05-2012, 11:41 PM
My initial thought was that there are easier designs to learn to SMT solder on, than those on the Smorgasboard. Bigger 1206 passives etc.

But later I thought why not aim high and educate, then those learning from the tutorials would be more capable. There are several tricks, why not highlight those tricks as they occur?

Besides we'll be better prepared for having to solder the Propeller 2...

Btw the FT232RL isn't too bad, its pins are a wider pitch than the propeller.

Cluso99
10-06-2012, 03:41 AM
Let us look at this logically...
I will take my CpuBlade as an example...

The references below refer to the pcb when viewed with the writing for the IO pins correctly oriented (i.e. xtal is at the bottom)
Solder the Propeller QFP (I extended the pins to make hand soldering easier)
Place a link in the via pins marked 3V3 (this links out the onboard 3v3 regulator) - just below IO "7" on the top left
All prop pins are now brought out to the outer edge holes
Meter between 5V (will now be 3v3) & GND and ensure no shorts
Meter between adjacent IO pins e.g. between 0-1, 1-2, 2-3, etc and ensure no shorts

Solder in capacitors C4 and C6 (0.1uF 0805)
Again meter between 5V(3v3) and GND at the pcb edge holes and ensure no shorts
Place a link in the lower 2 via pins (top right running down 3 vias marked at the lower end QE). This connects the reset line directly to the propeller and bypasses the onboard transistor reset circuit.
Attach a 3v3 power supply to the edge holes 5V(3v3) and GND (these run down left side from the top)
Turn on the power
Attach a propplug to the edge holes GND, /RST, 31, 30 (these run down the right side from the top and match the propplug connector)
You can now try PropTool to see if it correctly identifies the propeller chip. If so, so far so good.
If not, then a few propeller pins need to be checked (after removing the power and propplug) ...
The 4 power pins need to be metered from the top left edge hole marked 5V
The 4 ground pins and BOE pin need to be metered from the GND hole (2nd pin left side down from top)
The reset pin and the /RST hole (2nd pin right side down from top)
The P31 pin and the "31" hole (3rd pin right side down from top)
The P30 pin and the "30" hole (4th pin right side down from top)
Retry the tests above until it works

Apply power and propplug as before and...
Download TEST1 and vefiry it works (to be done)
Remove power and propplug and...
Solder in the xtal socket pins and insert a crystal after trimming the xtal pins to ??mm length - slightly longer is ok, but no shorter (or crystal using a toothpick under the xtal to prevent it touching the pads)
Apply power and propplug as before and...
Download TEST2 and verify it works (to be done)
Remove power and propplug and...
Solder in the EEPROM making sure you have it right way around - shorts between pins 1-4 (left side i.e. Q2 side) of the eeprom will not matter
Solder in RN1 (either way) - shorts on pins 5-8 (right side i.e. hole "23" side) will not matter
Place a link in the via pins marked WE (right side near holes "30" and "29"). This is the write enable pin for the eeprom.
Apply power and propplug as before and...
Download TEST3 into eeprom and verify it works (to be done)
Power off and back on and verify that TEST3 is in eeprom and works
Remove power and propplug and...
Solder in C2 (10uF 6V 0805) If a tantalum is used ensure the white bar is on the + side.
ONBOARD 3V3 REGULATOR OPTION (from 5V regulated supply)...
Solder in Q1 LDO regulator
Solder in C1 (10uF 6V 0805) If a tantalum is used ensure the white bar is on the + side.
Remove the 3V3 link fitted in 3. above
Retest supplying 5V

ONBOARD TRANSISTOR RESET CIRCUIT OPTION
Solder in Q2 (SOT23-3 npn transistor with inbuilt bias resistors DigiKey DDTC113ZCA-FDICT-ND)
If you do not have a transistor with inbuilt bias resistors, then a 10K 0805 can be soldered between the Q2 legs ensuring they do not short to C3
Solder in C3 (10nF 0805)
Swap the QE link (in 7 above) to the top pair of via pins (enables the onboard transistor cct)
This permits the use of a USB cheaper propplug equivalent without the reset circuit
Retest
Note that the link can be swapped to insert/remove the onboard transistor circuit

If you intend on overclocking, I suggest you also fit C5 & C7 (0.1uF 0805)
If you wish to prevent the eeprom from being overwritten, remove the link fitted in 21 above

If you do not have a meter, then use a superbright LED in series with a 4K7 resistor and 3V battery should do just fine.

I'm 58 and don't have much trouble with medium - to -medium small SMT. The correct soldering iron, good flux, 63/37 solder, and solder wick goes a long way.

I don't even use a 9-10" magnifier. I just use a hand held to check after I solder and apply solder wick to the offending bridges.

CpuBlade & Memblade
Gadget Gangster USB Protoboard


Even if you already have one or more of these products which were manufactured. (Please support these projects by buying them when you can!) I want to challenge us to DIY your own version from the Smogasboard.

Official "SMD Challenge" Thread:

OBC: Just a quick note...

MemBlade: U3 is a 74LVC1G97DBV and Q1 is the same 3v3 regulator as used in the CpuBlade
FT232: Q1 is a MMBT3904 or use the same as Q2 (inbuilt bias resistors) on CpuBlade and omit R3 ; use a 3mm LED.

I need to do a proper BOM - just no time atm. I can supply you with the 1x9 headers (they are female with long pins so they stack). I also have quite a few CpuBlade pcbs of the earlier rev (uses discrete resistors).

At some point I'd like to make a P2 based "gerber viewer", taking advantage of the 32 MB SDRAM, and the "big gerbers" would be a great test sample for display.

Thanks for that L,

I went to his Tindie site for a search.

I could not open the files in the current version of DipTrace 2.3.1.0.

Hmmm ok I'll take a look at it later in Diptrace. It might be a pad limit issue.

The gerber files were the final ones sent back by the fab house. My diptrace license at the time wasn't big enough to do the full panelization.

Ok, Was able to order from Jeff, so I'm good for now.

Thanks much!

EDIT BTW when I tried to open any file in PCB Layout, it gave a file format error.

Just in case someone cares, I have many of the original SpinSocket Flash PCBs.
There is also a SpinSocket dev-kit (http://www.microcsource.com/SpinSocket/SpinSocket-Collection.png) (in the black case) that I never really advertised.

PM if you're interested.

Good to know Steve.

I bookmarked it.

Are you using the "File/Import/Gerbers" command? It works ok for me, but some of the gerbers split into multiple layers for me, and that makes it complicated to import, but it does it eventually.

Attached is a native diptrace (my version is 2.2 at the moment) saved file, try and open it for me. There are definitely some layer issues with this - I think some layers are not correct, and the drill file doesn't line up either, so don't use it other than to test. If you really want this I could spent some more time getting it right... let me know

Doh!! I was trying to OPEN a Gerber file, and not import it. And the ironic part, I used to work for Gerber!

It must be late (early?) there. Thanks for the reply.

Diptrace file opened fine.

I'll take a look at it in the morning.

Thanks mate!

Just received my panel. What a beautiful work of art! Thanks Tubular!

Just trying to collect BOM's and such to make and order to build a few boards.

One that I am interested in is the IO dreamkit. I noticed that the Eagle file and BOM were never published. Any one have these? I know Bill Henning was going to produce these at on time, but it dropped off back in 2010.The board that got delivered does not match the photo on the Wiki. What is missing on the photo is the SMT R2R for the DAC. Anyone have the part number?

Bill, Hanno, Sapieha?

I can't help you with your part numbers but I just wanted to agree with you here.


What a beautiful work of art! Thanks Tubular!

I'd also like to thank everyone who contributed to the SmorgasBoard. I've looked at mine many times to see how the boards were laid out. I've learned a lot from it.

2012 was a very good year for Propeller board designs. We need to revive the availability info on these.
The Smorgasboard is especially wonderful.
