Description

The PCBSNR (printed circuit board simple n radical) is a simple and low power portable noise device based on the Radical Chip, which is a collaboration between Max Wainwright and John Richards (Dirty Electronics). This is a fairly simple build, and suitable for beginners or anyone who wants to make digital noise!

The design is based on the original stripboard version (seen in the video above), and is therefore very easy to modify and hack. All traces are visible, and cuts and front-side traces are labelled on the back of the PCB. This choice is inspired by dernulleffekt’s pop-neuron, which is itself a straight PCB adaptation of a protoboard circuit, with traces visible etc: take a look here.

The PCBSNR has some basic patch-ability, with pins for output, the two inputs, and ground (for patching in pull down sensors or other stuff). There is no protection on the inputs other than the built-in diodes in the PIC12F1840. So take care, try and keep it between 0-5V.

For patching with jumper cables it is recommended to use male pins on the board with female jumper wires, as pins are more durable. If you want to patch with e.g. a Bastl Kastl, just use male to female adapter cables.
