Batterimaennen – Im a Doctor

Posted on May 11th, 2013

Have you ever wised you could dance to all the music in the universe at one single point in time? Guess what!? Now you can! This song has made all previously created music in the history of fucking forever totally obsolete.  Dont worry, im a doctor.

Electric Santana Band – Oväntat Sväng

Posted on April 18th, 2013

Let us start by telling you a short story about a young boy called Kevin. He lives with his family in southern Finland. One day he met a really old tree and they made a SOUD and started dancing!

SJS-One modular expander

Posted on April 8th, 2013


 
- Would it not be nice if the SJS-One could be controlled by and control your analog modular synthesizer?

- Yes, yes it would.
 
- Is it very difficult to do?

- No, it’s not.

Let me show you a couple of mods you can do with the SJS-One Synth!

 

This post covers the following mods:

  • * Trigger input
    Any short pulse above a few volts will trigger the SJS-One to play a note (selected by CV).
  • * Trigger output
    Fires a pulse every time a note is triggered via MIDI.
  • * CV inputs
    These to connect via schottky diodes and a voltage divider directly to pins A0 and A1 on the Arduino, and can be used to select note to be played when triggered (or you know, whatever).

Basically what needs to be done is to protect the Arduino from ESD and harmful modular voltages. It doesn’t take kindly to ~12V on its inputs (or outputs).
So, we have to add Schottky diodes for super fast clamping to 5V. And for the CV inputs we also have to add a voltage divider, so we don’t loose all those volts above 5V. To keep it simple, we just cut the volts in half, so from a 0-10V CV, we instead get 0-5V. For the trigger output we need to add two transistors to get extra juicy trigger pulses.

If we take a look at the schematics, we see that pins A0, A1, A3, D2, D12, D14 and D15 on the Arduino are unused. Any of these can be configured to do stuf.
But, for now we’ll use A0 and A1 for CV inputs, D2 for trig in, and D12 for trig out.

What I did was to put all the extra components on a stripboard, connect it to the jacks and pots on the front panel, and to the SJS-One. I just soldered wires to the headers between the SJS-One and the Arduino. Since the Arduino has an onboard 5V voltage regulator, I can power the whole thing with my modular PSU using the Vin pin on the Arduino.

Of course we also need to modify the source code for the SJS-One. For this experiment, we modified the Drumstix code. One of the CV inputs is used to select which sound is triggered by the trigger input. Second CV not implemented yet.

Download modified Drumstix code!

Now, to be clear. These mods are just an example. Your imagination and coding skills are the limit!

In a future post, I’ll show how to add external audio input to the MAX261-filter, so you can use the SJS-One as a voltage controlled filter…

DIYFFS – ARCADE

Posted on March 22nd, 2013

Welcome dear human!
Today im gonna show you how to build and arcade controller for making and playing games. The box has all the standard stufs like Joystick and buttons but it also has some bonus controllers. These are 3 Analog Sliders, 3 Analog knobs and 3 Flip switches. The idea behing the controller is that it should be a nice tool for developing games and testing new stufs. Maybe you want to change the players size, speed, jump height, or whatever with the sliders or maybe use a flip switch to invert all colors, turn off music, turn on autofire…

Shruthibox – Project complete

Posted on March 16th, 2013

Remember this post?

Short story: I wanted a nice wooden case for my Shruthi-1 Synth, so I designed a 3D-model and CNC-milled it out of a plank of wood.

That first case, as practical and water proof as it was, wasn’t very beautiful. And a synth as well-crafted as the Shruthi deserves a better fate than that.
So, I started designing a 3D-model, that would be possible to mill in the CNC-mill at STPLN.

It’s based on the original case, which was made of cardboard, woodglue and sticky tape.

Three layers of the planky substance was needed, milled from both sides.

Many things were learned, some mistakes were made, lots of corners filleted

Then it went through an aging process in one of these.
Which made it look like this:

It was a fun project.

Acid December 2012 Megamix Tape

Posted on January 8th, 2013

This is the outcome of the Acid December thingy for this year. Two Megamixes of all the tracks from the compilation. They are about 45 minutes each and will fit very well on a 90 minutes cassette! And as you probably have noticed the artwork for this release (if printed out) will fit nicely in the cassette cover.
The main plan for us now is to record this on to as many cassettes as we can muster and sneak them in to second hand stores, flea markets, just drop them with the other tapes  so that people can find then and think “wft is this!?!?” and then buy it and go home and listen. And we hope they will like it because it sounds awesome when blasted in to the tape! (you should make one for yourself to!)

Look at this thing!

This has been a great project and we are really happy to have been a part of it and we would like to thank everyone that has given their frequencies over to our care!
Enjoy!
