It is a Geiger counter powered trigger and gate randomizer. The Geiger-Müller tube can be accessed through an alcove in the upper section of the module, allowing a radioactive sample to be placed, but module produces decent clicks even with just background radiation. An LED inside the alcove illuminates the tube for added effect.\u003c\/p\u003e\n\u003cp\u003eOn each Geiger counter click, the module generates a trigger output, which is available on the corresponding jack connector. The length of the trigger can be adjusted from 0.2ms to 27ms using a trimmer on the back PCB, to make the module better suited for each modular system.\u003c\/p\u003e\n\u003cp\u003eTriggers also stimulate the gate output, setting it to high after a trigger has happened. The length of the gate can be adjusted using the large knob in the center: from a very short duration, up to around 5 seconds. Each subsequent trigger will prolong the duration of the gate. An inverted gate output is available as well, providing a high signal when the gate is low.\u003c\/p\u003e\n\u003cp\u003eAll outputs can be completely disabled by flipping the switch. This keeps the Geiger counter running but disables all outputs. If there is any ongoing gate, it will not be immediately interrupted by flipping the switch.\u003c\/p\u003e\n\u003cp\u003eLastly, there is an LED on the input next to the tube alcove, signifying Geiger counter clicks. Two more LEDs are placed above the trigger output and gate output to allow for monitoring of the outputs.\u003c\/p\u003e\n\u003cp\u003eWebsite Page: \u003ca href=\"https:\/\/avalon-harmonics.com\/module\/Nucleus\/\" target=\"_blank\" title=\"https:\/\/avalon-harmonics.com\/module\/Nucleus\/\" rel=\"noopener\"\u003ehttps:\/\/avalon-harmonics.com\/module\/Nucleus\/\u003c\/a\u003e\u003cbr\u003eModularGrid Page: \u003ca href=\"https:\/\/modulargrid.net\/e\/avalon-harmonics-nucleus\" target=\"_blank\" title=\"https:\/\/modulargrid.net\/e\/avalon-harmonics-nucleus\" rel=\"noopener\"\u003ehttps:\/\/modulargrid.net\/e\/avalon-harmonics-nucleus\u003c\/a\u003e\u003cbr\u003eGitHub BOM \u0026amp; Source: \u003ca href=\"https:\/\/github.com\/Thorinair\/Avalon-Harmonics\/tree\/master\/Modules\/Nucleus\" target=\"_blank\" title=\"https:\/\/github.com\/Thorinair\/Avalon-Harmonics\/tree\/master\/Modules\/Nucleus\" rel=\"noopener\"\u003ehttps:\/\/github.com\/Thorinair\/Avalon-Harmonics\/tree\/master\/Modules\/Nucleus\u003c\/a\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003cbr\u003e- Geiger counter randomizer\u003cbr\u003e- Accessible Geiger-Müller tube\u003cbr\u003e- Randomized trigger output\u003cbr\u003e- Randomized gate output\u003cbr\u003e- Gate duration knob\u003cbr\u003e- Inverted gate output\u003cbr\u003e- Wrong polarity protection\u003cbr\u003e- Size: 8HP\u003cbr\u003e- Depth: 56mm\u003cbr\u003e- Power: +12V: 11mA, -12V: 0mA\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDISCLAIMER: Geiger-Müller tube is charged to around 400V on its anode. For your protection, these high voltage parts of the circuit are hidden inside a 3D printed enclosure and are not easily accessible. Opening the enclosure could expose you to these voltages even when the module is turned off due to a charge in the capacitors.
