Fizzle Loop Synth - 555 Timer Project

This is trhe 4th iteration of a little noise maker that I call the Fizzle Loop Synth. It's based around a couple of 555 timers, one that flases and LED and the other that makes a tone. A few passive componets are added to control the sound. Also incluided in this build is a 4040 binary counter IC and a 40106 Hex Schmitt trigger IC are also included in this version. This gives the synth the ability to create melodies and rythums wehich are controlled via 6 latching switches. The gerber files, schematic and board can be found in the Google drive link below along with the front panel design Google Drive https://drive.google.com/drive/folder... I've also published a step by step guide on my Instructables page which can be found below: https://www.instructables.com/555-Fiz...
