Ha! Yeah, the SCL is connected, the trace is on the back of the board. Your wiring looks good, unless something is shorted that I can't see. Of course, check everything with the multimeter to make sure there are no shorts and the proper voltages are where you expect it. also note that VSS is on R8, for proper alignment of the prop plug. The other thing is that I usually have the board plugged in before I plug in the prop plug, not sure if it makes a difference. Does the Prop or eeprom feel hot to the touch?
No, they don't feel hot, but they seem to be a bit warm.... So, what do I select on the Propeller Tool in order to just try to run a program?
Thanks.

Wait, the Propeller chip is definitely warm. I doubt that is ever a good sign...

The propeller tool just compiles and uploads. I've used GEAR before for emulation - check the wiki. I suspect that warm is a bad sign - that might be your problem. Once you let the smoke out, it's hard to get it back in...

Possibly - it's tough chip & sometimes it gets a little warm, though (like on my ybox). But hot to the touch would be a sure sign. Can you put the chip in another project and see if it fires up?
I updated the parts ordering to include.... PRICE! I've tried to keep them competitive without undercutting the price of projects. Of course, shipping is still $3.00. The updated parts page is www.gadgetgangster.com/parts

As mentioned, I switched from the blue LEDs to the red LEDs. Unfortunately, I forgot to change my resistors so they're really dim... Time to pull out the variable regulator and make a hack! I have a midterm though in 20 min, so it will have to wait...

Well, I wish I could say that I've finished, but that wouldn't be quite true. I got home today expecting to be able to just load my new code onto the chip (which I tested elsewhere), do a couple of tweaks, and submit. Unfortunately, I discovered that the LEDs in my project (an LED binary clock) were staying constantly lit: even when I removed the propeller! About an hour of trouble shooting has told me that I soldered in three of my chips backwards: inputs were becoming outputs, and outputs inputs. Unfortunately, I do all my soldering at the local university EE shop, which (as one might expect) is closed this late at night. So, I've attached a couple of pictures of my project, and I'll work some more on it on the morrow. Technically, I think I'll just make up a whole new board: this one become sort of messy quickly when I was trouble shooting. It will be revision four or five...
If you don't get any submissions (Nick), may I suggest that you try again in the summer? Maybe a Mid-Summers Night Challenge? The main difficulty for me is that I'm taking about 20 credits this quarter, and my day is packed. I hardly have time for any projects (GG or otherwise), with all the class work that I have to do. I suppose it's the same for many other potential college student designers.
So, I'll be submitting the project sometime next week (hopefully! It's been worked on in various forms since the begining of January...). It will be a binary LED clock with options to display H:M:S, M, S (since begining of day). I can't figure out a clean way to get 3 buttons in there, so I think I'll make the "turn-on" time 5pm.
I was thinking it would make sense to extend it, but I didn't want to be unfair to anyone who would be entering - but if I don't have any entrants, let's extend it until the 17th at Midnight, Pacific. That will give everyone 3 full weekends, if they need it (of course, you can enter earlier!).
@srlm - looks like an awesome project! What about putting the LED's on the board? That would make for a simplier build (but it wouldn't look as cool). Blue LED's would look nice, but they're pretty expensive. I also think there's something retro / cool about red led's. Don't worry - this won't be the last contest of all time, I'm sure we'll put something together before upew.
Another question; Is there any way to reduce the number of resistors? I guess if you connected them to a common cathode, but then the resistance required would vary with the number of LED's on.
Yay! That will give me time to sort out my propeller chip perils! Also, I will have time to order more things if the need arises.

I thought about putting the LEDs on the board, but that would require that I a) get 19 LEDs in a row, b) make it look nice. It's certainly possible,and I'll probably make a version like that, but I don't like the look. Too much clutter. The tape was just a hack to get it together: my final design will have the LEDs glued in, with the wires running along the back of the bar. That part will be left up to the user. I'll provide directions, but don't expect you to provide the drilled aluminum. That way, they can mount it any way they want. As for the resistors, they're actually one of the fun parts to solder. It's relaxing to bend them, stick them through the holes, then fold the legs over to hold them in place. If you do that before pulling out the soldering iron (along with placing all the sockets) then it's quite easy to whip through. A resistor network might work, but I don't have any in the correct value. The big time killer (and one reason why this project has been dragging on) was that I didn't have a good method to connect two wires to a the leads of and LED without alot clamps to hold it in place. I figured out a pretty good solution though, so in the end it only takes two minutes to make each strand. As for LED color, you're right: blue is more expensive than red (almost six or seven times!). I was thinking that several options could be offered: blue, red, green probably.
@SRLM: Your project looks great! I don't know if you have room, but is it possible for you to have your LED's on the boss board itself or on the full/half board with something connecting them like a ribbon cable...? then, you could have that part with a cheap RadioShack project enclosure... I don't know if it's possible or not, but it's just a suggestion....

I updated the Propeller Designers Pack to include a Prop, eeprom, 6Mhz xtal and an extra board. I also updated the SX Designers Pack to include an SX and an extra board.
TIP 120 Power Transistor
2.5mm TRS jack (for stuff like cell phones, fits at the same spot as the 3.5mm jacks)
Digital thermometer (uses 1-wire in a TO-92 package)
Vaati's project is now up, too - the Adjustable Power Supply. Not a canidate for this contest, but still a cool project (and great instructable).
@srlm -
I redid bean's Cylon Lights on the new board - it uses 8 lights. I didn't use current limiting resistors, but it worked fine. Adding LED's straight to the board might be messier for your project, though. Here's a photo of it on a prototype of the Boss Board;
I also just got labels in the mail today. These go on project baggies and they're meant to keep people who order multiple kits from being confused which is which. I think it also makes for a better presentation.
Myc Holmes is working on an entry for the PICaxe contest, but he sent me this 'quick reference guide' (pdf), which you might find helpful. He's working on a diptrace version, too (although it will require the paid version of diptrace - did you know the boss board has 700 holes?) I'm going to have him update the colors to match what we've been using and I'll add it to the site.
LASTLY - I added sorting to the find a project page! You can sort by popularity, price, date, or difficulty. This is ajax based, so it's pretty fast to update.

@Vaati - glad you got it all figured out! I know you were having some trouble in the beginning, now the hard part begins. My only suggestion is to keep it simple (especially for the contest) - sliced bread wasn't a complicated idea, but it sure was nice, same goes for electronics projects.
I added a few items to the inventory. One designer is working on a musical keyboard and requested I carry snap action switches. I wasn't sure if they'd fit on the board, but they work great! I also got 1xAAA battery holders. may not be useful for this contest, but it's an easy way to add power, especially if your project just needs 1.5V or 3V.
Switch by itself - .1 gap between each pin.
About 10 switches fit in a row. You can also see the battery holder on the top. The battery holder is 1.9" between pins.
Also got relays in the mail & they fit fine. Also, did anyone see Vaati's power supply project on Make?
Nick, could you please post a pdf or word doc on how to connect PS/2 and NES?· I need to figure that out today so I can start using that in my program, and the Gadget Gangster forums seem to be down as well as the entire site...·

'outages' should be fixed. The server wasn't down, but the router had mistakenly blocked a few IP address (part of DDoS / brute force protection). Just a few days left! I was digging thru some old files and I thought I'd share this. It was our original logo, hand drawn by me;
Here's a screenshot of the original website, too. This was back when the Gangster smoked (Personally, I still kind of prefer a smoking Gangster, but whatevs. That original banner was HUGE!
The Bacchus Clock is a binary LED clock based on the Propeller. There isn't really anything particularily revolutionary about it, mostly it's a long soldering job.
I thought about board mounting it, but unfortunately the LEDs take up too much space to do so. I figured out a way to make the soldering of the wires to the LEDs fairly easy, so that it's not too much pain. Each LED requires a single wire. I then mounted them onto the aluminum bar to get a nice spacing, and an attempt at a space age type feel (thin line with lights). I haven't quite figured out how I'm going to mount the Propeller board relative to the bar yet, but it will probably be in the same position. After all, half the reason for the project was for a technical solder job, so might as well display that. I thought about using a box with holes for the LEDs and power, but to fit everything I thought that would look too bulky and just to hobby level.
This is the fifth or sixth attempt at mine for this clock. I started in January with the GG full board, but unfortunately somewhere along the line I've lost the container that had the original attempts in there (along with all my tactile switches and other goodies!). This is the third attempt with the boss board. Hence, I've had to use the smaller crystals rather than the standard GG size can.
The clock right now is fairly simple and straight forward. Eventually I'll get to a design that has a few extra features, namely a set of three buttons for setting the time, and a temperature sensor with resistor so that I can include a PI loop and keep the crystal at a constant temperature. As it stands, the clock (based on crystal datasheet) can vary a second a day, or six minutes per year (+- perhaps another 6 minutes). Temperature variations should add some more to that.
This weekend I plan on getting the full build guide written up, and posted into the completed projects forum. As a side note, I named it the Bacchus clock because I think that it will drive me crazy eventually. I plan on mounting it on the wall to test this theory. If my posts start to seem a little chaotic, please pull the plug.
Here is an enrapturing movie of the Bacchus clock. Thanks to mctrivia for hosting.

The Bacchus Clock is a binary LED clock based on the Propeller. There isn't really anything particularily revolutionary about it, mostly it's a long soldering job.
Basic component list:
270 ohm resistors (17)

24LC256 EEPROM (1) (with socket)
1N4003 diode (1)
10 uF capacitor (3)
5v regulator (1)
3.3v regulator(1)
Four pin header (1)
10 K resistor (1)
2.1mm barrel jack (1)
5 Mhz crystal (1)
Assorted wires (?)
