Yeah I do toner-transfer but this atmega1284P arduino shield-compatible board I'm playing with was created by Iteadstudios I think (by one of the folks on arduino.cc)... Beautiful board, having rolled a number of single-sided toner transfer boards I drool over the detail.
I'd heard about PIC years and years ago, they were practically a gold standard in MCUs for a lot of applications were they? My thoughts is that I should stick with AVR since I know it well enough now, and dabble in ARM Cortex when I need to move up... Although I did just get my hands on that $4.30 TI LaunchPad thingamajig. Too many toys, not enough time!
Another near-future project I intend to complete is a MIDI postprocessor for some Yamaha toy digital drumset I bought years ago... it has a firmware bug where the hi-hat pad only sends an open-hihat MIDI instrument regardless of whether the pedal is depressed or not. Was going to pass the pedal signal through an AVR and passthru back to the drumset, then clean that bug out of the MIDI stream, and also add the ability to inject play-along MIDI programs triggered/initiated by a drum hit or whatever... haven't thought the last part out too much, but I am receiving a couple ATmega32U4 processors and I'm going to build that project as not just a MIDI postprocessor but an actual MIDI-USB adapter (I've seen a project where someone did that with the ATmega8U2 shipping with newer Arduino Uno and Megas, so I'll try to adapt that code for my uses)
