Atari Punk Junk Console

Using two of the most basic oscillators you can DIY, this particular circuit works great to modulate our main LFSR circuit. It also sounds pretty cool on its own. The main noise generator for our circuit. The basic circuit at play here is a Linear Feedback Shift Register (LFSR), a test circuit widely used in electrical engineering.

The power supply is a standard way of offering two different power sources (battery and AC Adapter) and then regulating them to a nice, steady, low-noise 5V. The switch is the master on/off for the circuit. If you`re dealing with oscillators and AC Adapters, it behooves you to filter the power supply. You don`t want excess noise to interfere with your sounds, especially when sampling/recording!
