AVR

Today, I decided to perform some tests on the Toner Transfer method for etching your own PCBs. I took the basic idea from Thomas Pfeifer's site. I gathered all the required materials, and started with a simple, ATtiny 2313 based circuit (done in Inkscape %-) that some day shall end in a midi mapper, allowing me to play drums in Blofeld's multi-mode with my channel-restricted MPD18 (one channel per bank).

In an attempt to keep the dust of what I've learned back in school, I once again started a couple electronics projects. Mainly microcontroller and LED based, tho. A 7-Segment-Display here, an ATtiny13-based 6-LED bargraph replacement for my harddisc LED there, and there are still a couple stepper motors I have lying around that would like to get my attention. And last but not least, there's the 12-LED binary clock that I want to build for a buddy of mine.
