[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.

[instrument/installation] 8-bit Woodtape Analog

8-bit Woodtape

8-bit Woodtape Analog, built using local wood material in Djerassi

On my first week in Djerassi Residency, I found out that lumbers is abundant in the area. The lumbers are going to be used as the material for fireplace during the winter. As someone from the tropical country, I’m unfamiliar with the use of woods for heating inside the house since it’s already hot in Indonesia. Since Laura Amador, the project manager of Djerassi said that we can pretty much use anything in the area, I decided to take one of the lumber to made an instrument.

[instrument] Dji Sam Soe Synth with Chaos Looper from SGMK

Dji Sam Soe Synth 100

Dji Sam Soe Synth 100, using the Dji Sam Soe box 100 year edition

An analog synthesizer I made using the Noise Looper circuit from SGMK (http://www.mechatronicart.ch/). I built two of this synth with different cans of Dji Sam Soe special editions. The circuit is using PT2399, a digital delay chip which you could get from the local electronic store in your city. Many information about PT2399 can be found here. Video, documentations and instructions are bellow.

[instrument] Naniwa So Shi (Story From Osaka) Synthesizer

naniwaSOSHI

Naniwa So Shi mini sythesizer

A week ago, my good friend Geger gave me a tin box when we were cleaning his house. The box is a packaging for some sweets from Osaka Japan. My friend Sachiko translate the writing on the box. It says “Naniwa So Shi”, which means Story/Journey from Osaka. I really like the design, and how light the box is. So I decided to use it as the case for my mini analog synth.

555 Simple Oscillator [tutorial]

The easiest and cheapest way to make an oscillator is using the famous 555 timer chip, which in Indonesia it cost roughly about Rp. 800,-. It’s a simple oscillator which produced a square wave  signals. You can also call it as “Poor man’s oscillator” :P. Even as simple as it is, or as cheap as it is, this oscillator is still a powerful instrument. I build this oscillator based on “Laser Ray” Schematic from “50 555 Circuits” E-book by Collin Mitchel. I also made the EagleCAD schematic and board file bellow.
