At this post I’m gonna share a simple bio-synthesizer using the all time favourite CD4093 Integrated Circuits. This circuit is very simple it will take you about less than 10 minutes to solder. I always use this bio-synthesizer as an introduction to electronics, like the workshops series in Lab in a Lab – Age of Wonderland as an example. Bellow you will find the PCB design and layout.
The idea in making this simple biosynthesizer started after the Solder Synth Sense Sore Sore Sip workshop. There are many version of this bio-synth and we keep designing new design to make more people interested in electronics. Bellow is a video sample of Kangaroo version I developed in May 2014.
You might give it a try, the sensor area basically response to human touch, humidity, and organic matters. You can also put LDR or other sensor on that area. Have fun!
