I ordered my kit through Make Magazine. I assembled it, and it seems I have a short from VCC (5V) to GND. (Ohmmeter reads 0.2 Ohms, which is the same reading you get if you touch the leads together).
First of all, did you supply kits to Make magazine (and might therefore support me) or did they just make a bunch themselves? I would understand if you were unwilling to support kits you didn't put together. FYI, the board has black soldermask and says nootropic design on it.
I visually inspected the assembled board, and did not see any shorts.
I removed the 7805 and the electrolytic output cap, and that didn't fix the problem (still 0.2 Ohms). I pulled the processor out of the socket because that is easy to do. Still short. I took out one of the bypass caps and did a little bit of damage to the PCB in the process. Now I'm afraid if I keep going I will destroy the board. I'm an EE, but I usually have technicians do this kind of thing. ;-) I can't ask a tech to do this, though, because my techs are busy with real work. I'm doing it on my free time.
A couple of things:
1) I did put the socket on backwards, but that shouldn't matter (right?) The uProcessor pin one location is the same as shown in the silkscreen. During assembly, I didn't notice that the socket had a polarity indicator.
2) Even though the ohmmeter shows a dead short from VCC to GND, the 7805 doesn't get warm. Also, the power supply (not yours) makes a faint sound at something like 2 Hz. I'm thinking maybe the power supply is cycling in and out of a fault protection mode, and that is why I hear the sound (and is also why the 7805 doesn't get hot). Two different power supplies do this, and they work fine on other products.
I'm not sure what to do now. Any chance of sending me a freebie? I can't confirm that the board or a component is defective. There could be a short somewhere that is not visible (under a component, for example). Or maybe the soldermask got scraped off of the GND fill somewhere, and a little solder from one of the VCC pads bridged over to it. I don't have a microscope at home, and I wouldn't be able to see that without one. I could send this board back to you if you want to try to figure out what is wrong with it. If you do send me a new one, I will check the bare board for power-ground shorts before starting assembly, and will proceed in a more logical fashion to avoid this kind of problem.
