  • Waiting for exposure film

    After having barbecued the µC by 12V supply voltage, I decided to etch new pcbs instead of wiring everything on breadboard.

    At the moment I'm waiting for exposure film I ordered for etching. I tried laser printing on conventional transparency film, but the result was not that good.

    Today I got the milled mounting adapter for the 43mm mount. Special thanks to my collegue Oliver for this! Unfortunately I couldn't do it on my own because milling wood is too loud for my neighbors... Special thanks to my neighbors for this! :( )

    Now it's time for some coding...
