A very small chiptune synthesizer and player. Sound is made with an 8-bit microcontroller (Attiny85) and tries to mimic a classical sound chip used in video game consoles from the 80s.
Pretty much inspired by 1-bit symphony by Tristan Perich and lft/kryo's project.
- AVR ATtiny85
- CR2032 coin cell battery
- 1K resistor
- 0.1uf capacitor
- 3.5mm audio jack
- Push button
Note: This schematic is old and inaccurate (although similar). Please see this tutorial as the protoboard picture reflects more accurately the current design.
- Music written in an MML-like language
- HTML5 editor with sound emulator
- Change current parser for a standard MML parser
