A chiptune music player made from the Notacon 8 visitor badge in one day. Released for Pixel Jam 2011. 1st place Wild Demo Category.
The sound is produced by a SN76489 PSG sound chip. It has three square waves, one noise channel and built-in analog sound amplifier. The music is a VGM file which was emailed to me overnight.
I messed up the breadboard area by lining up IC sockets on one side leaving my no space (or time) to fit a 3.5Mhz oscillator and two banks of 32K EEPROMs. I worked around my error by having the microcontroller(arduino based) generate the PSG clock signal via PWM and moving the song data into flash memory (chopped to 25K). I think all the extra wires made it look cooler.
Somewhere in Ohio, there is a hotel alarm clock missing a speaker and capacitor.
