[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.

[module/tutorial] Audio Amplifier

386amp layout

Board Layout

 

Often, we need an audio amplifier for low signal devices such as microphone or piezo transducer. This is a simple low power audio amplifier based on LM386, a relatively cheap IC that’s available in most electronic store. Schematic, Part List and PCB design available below.

Sinau Skema Sirkuit Sintesis Suara Sob [workshop]

Sinau Skema Sirkuit Sintesis Suara Sob 33

Hand drawn PCB design from Julian “togar” Abraham

After the Solder Synth Sense Sore Sore Sip workshop, Marc, Togar and I were in a workshopology discussion about creating an intense workshop sessions to get the participants get to know about DIY electronics. We agreed that the workshops on making simple electronic circuit such as Micronoise, Synth Sense, Atari Punk Console, are quite nice for the participants to have general idea on how electronic circuit works. However, we thought this workshop modules are not enough to really kick themselves in to creating or experimenting with electronics. Continue reading

Atari Punk Console [tutorial]

Atari Punk Console is one of my all time favorite synth. It’s a combination of two 555 timer chip (or IC 556) oscillator which produced 2 layers of square wave sounds. Atari Punk Console (APC) is a name given by Kaustic Machines crew because of the “low-fi” sound it produced is similar to the games from Atari Consoles in the 80’s, with square wave similar from Atari 2600. In this tutorial I’m giving schematic, EagleCad files and PCB design of APC using NE556 Integrated Circuit. Check out the video above to hear how it sounds :)

Hex Oscillator using 40106 [tutorial]

As we can see in Quad Oscillator using 4093, combining some oscillators is quite fun. It gives layers on our sounds and gives a sense of thickness on it. Besides Nand-Gate, we can also uses Schmitt-trigger (inverter) as oscillators using the same (more or less) logic. One of the most popular and easy to found chips out there is the 40106 hex-schmitt triggers which means it contain 6 inverters that each one of them can be easily turn as oscillators. There’s loads and loads of tutorials using these chip, I followed the flux monkey tutorials and modify it bellow. Check out the video to hear how it sound above. :D
