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. :)
