Radical22



The Radical22 is a voltage controlled digital noise module that goes from sharp clicks to glitchy fm to an mp3 wash to harsh noise to video game sawteeth, to silence. Feed it LFOs, envelopes, audio, slewed stuff, knob twiddles, or joystick rides for hours of fun. Plenty of frequencies to filter, or simply plug it straight into an amp and sequence the three inputs. More digital than a box of chocolate fingers.




Features

32 programs/algorithms
2 CVs (pots + CVs in) - program control
1 CV (pot + CV in) - program select

Description
The Radical22 is ongoing work by Dirty Electronics and Max Wainwright born out of the idea of Microcomputer Music: a music made from mini microprocessors and raw electronics that is always in-flux, noisy and may be overwritten.

This module has 32 programs/algorithms that can be selected by a control voltage. Each program has a unique characteristic and chaotic behaviour that can be selected and explored through control voltages.

The price is €180+VAT. You can buy it at noise.kitchen or in my shop, here. Or (especially if you are in the UK or hate the EU) from Dirty Electronics.

Spec
power consumption: +12V: <33mA, -12V: <26mA
10pin power connector (diode protected)
14HP
depth 40mm (including power connector)

Power
1. Disconnect the mains power
2. Connect the module's ribbon cable supplied. The red line on the cable (pin number one) should match the -12V rail both on the module and the power bus board.
3. Double-check the connector and pins are correctly aligned
We do not accept any responsibility for damages caused by the wrong power supply connection, or inputting voltages outside Eurorack power levels (+/-12V).

Customise the code
The code is available here: radical22.zip. or at GitHub The code (LINK) for the Radical22 is available on GitHub under the CC license Attribution-NonCommercial-ShareAlike 4.0 International (CC BY-NC-SA 4.0). It can also be download from the Dirty Electronics website.

Programming the PIC12F1822 or PIC12F1840
Use MPLAB X IDE and XC8 compiler, and Pickit 3 to program the chip.

Please note that dealing with MPLabX is a painful experience. Don't buy this as your first programming thing, get an Arduino or something. MPLab doesn't want to upload usually, and the code is not written with the intent of sharing - comments are few. Radical22 isn't a development platform. There is, however, memory left and the programs can easily be permutated by replacing numbers and signs. Have fun.
