- how to build simple synths

Lab 01: Simple synths

Try and build an analog synth. Note, the chip in the photos and diagrams is the same as the one in the video, they just change numbers depending on who makes it. Yours is the CD40106BE.

If you have a real kit, build it, if not follow along on Tinkercad. Up to you!

To hook up the basic circuit folllow this simple video for basic instructions:

• There are several capacitors in your kit. Play with them and experiment with hooking up more than one oscillator. Have fun.

Here's what you are building in some variation:
