[instrument] 8-bit Mixtape – Classic

8-bit Mixtape Classic Compilation Detail

Continuing in developing the 8-bit Mixtape, here’s the new development of 8-bit Mixtape, I give it as “Classic” edition. It added some new features especially the rechargeable battery. The full features are:

– 8 algorithms of 1 line C music
– 2 potentiometer controlling variables
– 2 button for next and previous algorithms
– volume control on the side
– 1 LED (yellow) on/off indicator
– 1 LED (pink) signal indicator
– 1 Li on 3.7V rechargeable battery with up to 8 hours playing time
– micro USB connector for battery charger or AC to DC converter
– battery protection
– 3.5mm mono audio connector
– ON/OFF switch
– programming connector (working on progress/not tested)
– attachable potentiometer and knobs to make cassette fits in the case
– destroyed classic cassette records with case and cover bought for 2,000 IDR from second hand market

I met John Yingling of The World Underground as he was documenting the underground scene of Yogyakarta. He really liked 8-bit Mixtape that initiated by Marc Dusseiller – Dusjagr, Budi Prakosa/Iyok – Manticore, and myself (Andreas Siagian/Ucok) and wanted to have one of it for himself. Documentation of 8-bit Mixtape >>[[here]]<<. I decided to build a custom 8-bit Mixtape using a NES cartridge as a token how I was impressed by his dedication on his work. Documentation of his travel in Indonesia can be seen >>[[here]]<<, I managed to made a small video documentation of the 8-bit Mixtape NES bellow.

8-bit Mixtape v0.4

8-bit Mixtape v0.4

8-bit Mixtape is a project started on the early foundation of Lifepatch back in 2012. It was initiated by Marc Dusseiller – Dusjagr, Budi Prakosa/Iyok – Manticore, and Andreas Siagian/Ucok – Squaresolid (myself). The idea was to make a simple synthesizer that could play the 1 line algorithmic symphony. We were working using Attinny 85 chip with Processing and tried to develop a synthesizer with 2 potentiometer and 2 buttons. We keep it minimal. The project then developed with many other individuals.

Squaresynth kit di IBP Squaresynth - DIY Electronic Workshop Medialab Melbourne

Squaresynth module kit for DIY electronic workshop in MediaLab Melbourne

As part of the public program of The Instrument Builders Project in Melbourne Australia, I conducted a workshop on DIY electronic synthesizer making. The workshop was using Squaresynth module and I gave it along with Benjamin Kolaitis and Lintang Raditya. The workshop is hosted by MediaLab Melbourne. Photo documentation bellow.

[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.
