Simple n Radical – SNR, PCBSNR, DIYPCBSNR (I had a thing with acronyms at the time) – is a series of small battery powered digital chaotic noise generators based on the Radical Chip.
Originally a stripboard DIY design for using the Radical Chip without a Mute Synth 4.0, the instructions turned into workshops in a UK tour with Dirty Electronics.
Go to the shop to buy one, or check our dealers.
Other additions in later versions were a power switch and a gradual growth of pins: to patch in voltages, to DC-couple the output and to send the output to ring for headphone use.
New code with 64 algorithims (instead of 45; 9 of the 45 were culled) was added in the summer of 2023.
• Two controls
• Random Algorithm select button
• 64 algorithms
• Mini jack output
• Patchable with optional adapters
• Mounting holes to screw onto e.g. a plank (PCB versions only)
Size: 61x46x16.6mm
Weight: ~20g
Power supply: 9V battery.
Power consumption: around 7mA for the PCBSNR with high-efficiency leds, stripboard versions have normal red leds and draw around 13mA (both at 9V)
