If you look back, you will notice that I found instructions on how to build an LED cube 9 full years ago (May 4th, 2011!). I ordered the parts in early September of that year and started building soon after. I finished the boards sometime around April of 2012 but wasn't confident enough in my work to try and turn it on. For the last 8 years it has been sitting on & under my desk.
This past week I decided it was time to actually try to make it work. I reviewed the boards and found a couple of broken wires to fix, found 2 solder traces that were wrong but over all everything looked good.
I hooked it up to the USBTiny programmer which was hooked to a Raspberry Pi (wanted Linux), sent the 'test' program to it and PRESTO it worked. I was floored. I did find a couple of columns didn't light appropriately which turned up a couple broken solder joints that I didn't notice. Got those fixed and it works perfect.
Next up is to get the main program working correctly... I suspect I have a solder trace wrong somewhere but not sure yet, haven't dug into it that much yet.
Here is a short video of the test program running.
