[tutorial] Simple Bio-Synth [instrument]

Tiger Biosynth - Squaresolid

Tiger Biosynth produced in Dutch Design Week 2014

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.

[module | tutorial] squaresynth

Squaresynth is a module of a costumized simple synthesizer based on quad oscillator on my earlier post here. It uses the same chip, 4093 and modified it as a touch/moist sensor. I developed Squaresynth for workshop purpose, to invite the participants learning the basic electronics through introductions of electronics logis such as oscillator, introduction in reading schematics, and also introduction on electronic components. The demo showed how it sound above. Documentation, schematic, PCB  design bellow.

[tutorial] Synth Sense: Touch and Moist Synthesizer using CD4093-Quad 2-input NAND Schmitt Trigger

In this post I’m sharing a tutorial on how to make a simple synthesizer which react to moisture and touch from human body. Originally, this synthesizer is based on quad oscillator using 4093, squarenoise~ module which I used for a workshop on Ho Chi Minh City, Vietnam.  This module is quite simple and only using several electronic components which makes it suitable for beginners or as an introduction to DIY electronics. See the video above to see how it sounds and interacts.
