glitch unground [sound]

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.

square[noise~] DIY synth making [workshop] for Carp2Dragon [residency]

workshop squarenoise 05

Next day after the performance I did at I’m Yours Cafe, I gave a workshop to make simple pocket-size DIY synthesizer. This is my first own module which I created for lifepatch and I called it square[noise~]. The module are using CD4093 quad nand gate which produce a square wave sound signals.

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

Senja Art Exhibition closing [performance]

After the opening performance, the organizer asked us to do another performance for the closing ceremony, 2 days after the opening. Since everyone said yes, we did another performance with (almost) the same set. With Marc Dusjagr also joining us :). We all sat in the center of the exhibition room and sets our instruments there. Dusjagr and me playing some noise and jamming while enjoying the visuals made by JoanPrahara Bumi and manticore (Iyok).

Senja Art Exhibition opening [performance]

lifepatch + dusjagr opening performance for Senja Art Exhibition

lifepatch + dusjagr opening performance for Senja Art Exhibition

In end of January, lifepatch are invited to participate in Senja Art Exhibition. The organizer asked us to do a workshop and performance for this event. From lifepatch, manticore (Iyok), Joan Prahara Bumi and me did a little jamming session for the session, with Dusjagr joining us for the fun with his DIY instruments :D

Quad Oscillator using 4093 [tutorial]

After SITS oscillator, let’s try making combining some oscillators into one sound output. There’s many ways for us to build a lo-fi instruments from cheap electronics part that we can easily find in the nearest electronic store on our town. For an example is the Quad 2-input NAND gate CD4093 (Integrated Circuit / IC) which is only about Rp. 2000,-. Like the name, this IC have 4 nand gate which each of the gate can be easily transform as an oscillator. The oscillator will produce square wave sound as Nandgate produce binary signals as the output. There are many tutorials about using this IC, my personal favorite is micro-noise from Swiss Mechatronic Art Society (SGMK) and this simple 4 block Quad Oscillator from Flux monkey which I highly recommend for those of you would like to learn basic understanding on oscillators. In this post, I’m sharing the Quad osc that I modified from flux monkey along with schematics, PCB layout and print in EagleCAD files. Check the video above to see how it sounds. :)

Simple White Noise Oscillator [tutorial]

I always wanted to make a white noise oscillator that is simple and powerful using easily found components in Indonesia. I received a schematic from a friend of mine Lintang Kenalirangkaipakai (he didn’t create it, he found it from the internet) and give it a try to see how it sounds. I have seen this schematic when I’m surfing the internet, however I never give it a try or maybe I was too lazy :P. The schematic is very simple, only using several part that in total cost you less than Rp.10.000,- and you can get it in any electronic store in your city. Since I like it, I thought I share it along with a PCB design, EagleCAD board and schematic files and layout so anyone can use it. Or you could just prepare your breadboard (like I did) if you’re not convinced with the sound on the video and want to check it out on yourself. :)

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.

lifepatch AV performance in DYE 2012 by manticore, squaresolid and antirender [performance]

On the 15 December 2012, we did an audiovisual performance for Dance Your Eyes Festival 2012 in Gedung Indonesia Menggugat, Bandung Indonesia. Three members of lifepatch that was doing the performance are: manticore (visual), antirender (sound) and me (sound – using squaresolid as a nickname). Yeah, squaresolid was actually my blog on animal documentation and also my troll name in internet forums, but the organizer insisted we use nicknames for the performance and so we did. I have small objection to that but I threw it away on the end. Besides, the name is started to sticks on my personality anyway :D
