A special jar made from borosilicate filled with uranium order is set in front of a Geiger counter which detects radiation events from the decaying ore. These events are mapped to a number of outputs including gates, triggers and CV allowing unique and random events to be created and sent around your patch. While it may seem like a novel idea, it is a unique way to generate random events and keep your ideas interesting and unpredictable.+
Here’s what Nervous Squirrel is saying:
Features and controls
There is a trigger output that creates a pulse whenever an event is detected, and also a group of six outputs that can be set as either triggers or gates. The group of six outputs are activated again depending on the activity from the ore. A relatively long pause followed by two clicks in quick succession will activate output number 1, for example.
There are three knobs for adjusting the CV output:
RANGE: Sets the range of the voltage from 0 to 10Vpp. Adjust this to create subtle variations or dramatic jumps.
OFFSET: Sets the area in which the control voltage operates. For example, if the range is set to max then the offset can be used to set the voltages to operate from -5V to +5V or from 0V to 10V.
GLIDE: Sets the amount of glide between the changes in voltage levels. Set to the max and remove the jar to create slowly drifting voltages triggered by background radiation.
The jar is removable, but pushes into place with a fairly tight fit, to prevent it from falling out of portable modular systems. The activity of the module changes when the jar is removed. Take care when removing or replacing the jar.
The lid of the jar has been glued shut. Please do not attempt to open the jar – handling/inhaling/swallowing dust or fragments of the ore must be avoided.
A switch has been provided to turn off the internal Geiger counter click.
How it works
The system initially waits for three clicks and then uses the position of the middle click to set the proportional level of the CV output. For example, if the central click occurs relatively close to the first, the voltage will be lower.
The system then waits for the next click to replace click 3, and re-assigns the previous 2 and 3 to the new 1 and 2.
