My project proposal on lab process in hacking and investigation on products that could be easily accessed in convenience stores, grocery stores and $1 stores is presented in Interactivos?’16.
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.
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.
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.
In Djerassi, Budi Prakosa and I made an experiment in synchronising audio to an old TV in Djerassi’s lounge. With Laura’s permission, we took the TV and play with it in our studio. I hook some analog synth to the TV signal, while Iyok made some codes for visualisation of the 8-bit mixtape. Some documentation of the experiment bellow.
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.
Several recording of glitches from interaction between external hardware such as flash drives and modems with a computer. The sound composition created from the interaction of these devices with a computer and also interaction of my usage browsing and opening files on the external hardwares.
During 2013 in Yogyakarta, lifepatch members have been continuously working in building the bio-electronic lab at our home base. We managed to convinced our landlord to use the room just beside the house for our lab. Earlier before patching the lab, we were making future plans (pic above) on what to do with the house. At first, we were thinking to use the room as a community store as an income to support the financial of lifepatch. But then we thought the ideal plan is to convert it as a lab, to support our projects and activities in Bio-Design for The Real World.
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.
