Thor

Ok so I've been doing work on my Tron Disc Mod here (links to all important pages about it). My problem is, after I posted the first video, I went to making some more modifications to it, and in the process, somehow made the Mini unresponsive to my programming. I use the FTDI Basic board to communicate with the Mini. What I mean by it being unresponsive is that the TX light on the board flashes, but the RX light does not. So that tells me my system is trying to send commands, but the Mini isn't responding. What I think killed it was an incorrect measurement of current I did at one point. Basically, rather than putting the multimeter in line like you're supposed to do to measure current, I put it in parallel, shorting the circuit. That was stupid of me because I've measured current before, it's just been a while since the last time I did it (10+ years). I can't remember where I made that measurement, I just remember trying to make it.

Now here's the thing, I ordered a new Mini thinking that it was the problem, but the new mini reacts the same way, so either the new mini is DOA out of the box, or the FTDI Basic board isn't working properly. Any opinions?
