    LED Cube 8x8x8

    So I am (still) building this and I have a question... I was having trouble with the LEDs, some row-column combinations were lighting multiple LEDs and a couple didn't light at all. Turns out I (somehow) missed soldering the anodes between layers for an entire column! Once I took care of that, that fixed the three LEDs lighting up at a time, but I still had a couple of other LEDs ghosting when one or the other was turned on. I found one open LED and one shorted LED - luckily on the outside column! I guess that happened when I was soldering the layers together... I swear I tested each layer as I built it. After all of that, I powered it up and the only thing that happens is that the "status" LEDs flicker back and forth. The entire cube is off.

I was having trouble with the LEDs, some row-column combinations were lighting multiple LEDs and a couple didn't light at all. Turns out I (somehow) missed soldering the anodes between layers for an entire column! Once I took care of that, that fixed the three LEDs lighting up at a time, but I still had a couple of other LEDs ghosting when one or the other was turned on. I found one open LED and one shorted LED - luckily on the outside column! I guess that happened when I was soldering the layers together... I swear I tested each layer as I built it. After all of that, I powered it up and the only thing that happens is that the "status" LEDs flicker back and forth. The entire cube is off. If I hit either the "deubg" switch or the "status" switch, the "status" LEDs stop flickering and only one remains lit. The cube then begins going through it's test program. The problem is that four rows-columns are constant lit and a couple of LEDs only come on during certain cycles, but not others. Since the entire cube is off before the processor beings running, that would tend to tell me that nothing is shorted. Also, when I press either the "status" or "debug" switches after the program is running, nothing happens. When I first programmed the AVR, I used avrdude running under Ubuntu Linux and an AVRasp programmer. Every time I try to program the IC, it tells me that it expects a certain signature, but that the one returned by the IC is different and that I need to check my IC since it doesn't appear (to the programmer) to be an ATmega32. The IC I am using is ATMEGA32 16PU 1403. This is the same chip shown on the photos here, with the exception of the last line, which I didn't think should matter. I am able to program the IC anyway using the -F (force program) switch in avrdude, but I am wondering if this might be my problem rather than a hardware issue. Any thoughts, ideas, or help? I've been working on this freaking thing on and off for over a year now, so I am ready to see some final results! Thanks...
