Introduction: How to Build a Simple 555 Synth
This instructable shows how to build a simple synth using a 555 timer.
Step 1: Parts Needed
1 270k ohm potentiometer ( I used two. 1 250k ohm for major pitch changes and a 30k ohm slide potentiometer for finer adjustment
1. 10ohm resistor
1. 220 ohm resistor
1. 1k ohm resistor
1. .1uf capacitor
1. 555 timer
1. Audio jack
Step 2: The Case
Find a case and drill out the holes needed for the switch, potentiometer, and audio jack. ( I added extra switches for possible additions I plan on doing)
Step 3: The Circuit
Solder the circuit together and then attach the switch, potentiometer, and jack to the case.
