The Nand Synth is a great project to begin with, simple and super fun.  The Nand synth offers 4 square wave outputs that modulate each other.  Full kits coming soon, but check out the BOM for now if you care to buy your own components.  The PCB has a detailed screen print that shows you exactly where and how to place even polarized components.  Enjoy!

Check out this NAND SYNTH VIDEO (that we did not make) that shows the functionality of the Nand Synth!
