Roy, yes through GG. I'm working on information and links to go on a GG page now. It'll be about a month before GG has the production boards, so I'll need to discuss pre-order arrangements with Nick.
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 of my board, I will mail one to you.
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.
Looks like the Max72 Board USB. Nice board!
I like Ariba's Propino too.
There have been some really neat designs over the years. One of my hopes by combining boards is that boards like Max72's get some attention and use. I think his initial post slipped under the radar and only got a single reply or two
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.
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.
Not like I need another project....and I don't want to steal any thunder from our GG friends BUT:
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.

They looked good. I'll send you the schematics when I'm back home in a few days.

In the mean time, if anyone would like a hi res image just PM me and I'll reply with one

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

With any luck this panel will 'float all boats'

Should have the page up for them this week and I'll start putting them in envelopes!
