Neutron Orgone accumulator

[defex]

Here is my new euro module programmed in arduino IDE. there are a few soundcloud examples on the page linked below.

It runs on a teensy 3.1 and has real time v/oct expo converter. There are 11 simultaneous oscillators, an 88khz output sample rate.

There is a 4 pole 19khz output filter and 4 attenuverting control voltage inputs.

The code is available on github, so you could program it to do whatever you like.

Oh wow, very nice!

And amazing performance out of such a small board.

For a long time i was working on something called "neutron shield modulator" which was an arduino based one, this can do a lot of the same things, in some cases actually more.

It is sold as an oscillator but if you wanted to make it do anything else:

open source

arduino IDE compatible (with teensyduino)

96 MHZ ARM cpu (fast enough to real time calculate exponential conversion from 1v/oct to frequency in floating point, without bothering your program. no lookup tables and bend input cheating!)

10 programmable knobs

8 programmable switches

4 attenuverted CV inputs

gate input

trimmed/buffered ADC input (usually for 1V/oct)

12 bit DAC output (88khz in this case)

level shifted unfiltered 1/0 output.

7 extra GPIO pins left on teensy for hacking. 4 are ADC in, one is PWM out.

external voltage reference. with buffer for pots.

teensy is on its own regulator, nothing else uses its power (less noise)

MOTM or euro power, works at +-12 or +-15v

optional 5v onboard regulator.

I am thinking of making blank cards (or a template, at least) you can put over the controls to write your own control names on.

And I plan to do my own MOTM format panel, will share the artwork at least.

It sounds great, and I want to play with the code

Well i did add a couple of holes so you can attach it to brackets, but you will be doing a lot of wiring.

Something i did not think of is showing which of the switch pads you need to connect your toggle switches to, there are 6 for each switch, but you actually only need to connect 2 wires to your toggle switches.

Ill put it on my list and make a diagram on the web page for 5U wiring.

I've wired the MOTM version of Dustin's Dual Mirror Core/Complex VCO, and a MFOS Soundlab Plus. Nothing scares me.

Perfect for experimental coding and learning DSP.
I'll take one soon!
