This was my first try developing my own pcb with the toner transfer method. I did this project many years back but it works perfectly to this day.

It filters an audio signal and drives led strips so they pulsate to the beat of a song.

    Nicely done. I have given up on toner transfer and instead use a laser attached to a 3D printer to burn away spraypaint.

    Alignment on double sided boards is difficult though.
