Another musical instrument created! Thanks to Buranelectrix for creating this great little project based on the Atmel ATmega328P chip. I’ll be making one on a proper fabricated PCB in the near future.

The design runs at 16 MHz, with six buttons, five potentiometers and eight LEDs. Four individually generated 1-bit sounds are mixed through a 3-bit resistor DAC into a wonderfully compact little noise machine. The next post lets this one make some noise.
