back to controller post

It all started at July 23, 2011, 02:29:40 PM. I posted a question on Wiring Forum to get assistance for my 16 rotary encoder MIDI controller project.

I used a Wiring v. 1.0 board, Processing and the madecau/QuadEncoder library.

The coolest part was to get get help by Mr. Hernando Barragán himself, who initiated the Wiring project. Arduino is a descendant of Wiring, so I got help from an open-source celebrity!

Putting the code together was pretty straight forward, the tricky part was building the whole thing and getting it into an enclosure.

I used jumper cables and a breadboard. No soldering. Why? Because I wanted a prototype that I could use in the studio and see in which ways it could be improved.

I did not wanted to wait long, so going out and getting an enclosure didn’t seem very attractive. I chose the SparkFun box, yes, the one you get your parts in.

Now Pammela Rojas did the magic, she put out a pretty sturdy enclosure and montage with just this cardboard box, more cardboard, masking tape and double-sided tape.The opening for the USB cable was improved with a piece of protective foam that came with the Wiring board.

That seemed so ecologic to me, that I decided to name the device “œkontroll”.

I write about this old stuff, because the moment has come for the œkontroll to evolve! I am planning on making a dedicated controller for Logic’s Ultrabeat. I think I’ll add a bit more functionality and I hope I can get a beautiful enclosure by Hard Mod electronics (who, by the way, is modding my Monotribe).

See you around!
