Build Your Own Quantum Entropy Engine What's Included: Pre-programmed and tested PCBAs (main control board, nixie display board) Authentic IN-14 nixie tubes 44-pin display driver IC 2x Rotary encoder with knob LED and current-limiting components Laser-cut enclosure panels (choice of basswood or clear acrylic) Hardware and fasteners 2x rechargeable 18650 lithium-ion batteries Detailed assembly guide with photos and troubleshooting tips What You'll Need: Soldering iron and intermediate soldering skills Wire cutters and PCB holder recommended ~2-3 hours assembly time Glue/adhesive Your Build Experience: This is a semi-assembled kit designed for intermediate builders. The complex SMD components are (mostly) pre-soldered and tested. You'll install and solder the through-hole components including the vintage nixie tubes, rotary encoder(s), and LED. The HV IC driver necessary to drive the nixie tubes is a 44-pin surface mounted component.ESD sensitive components shipped in ESD bags for precaution. Features: True Quantum Randomness: Custom cryptographic circuit harvesting entropy from quantum tunneling events Die Selection: Rotary knob for D3, D4, D6, D8, D10, D12, D20, and D100 Die Selection: Second rotary knob for 1D, 2D, 3D, 4D, 5D, 6D, 8D, 10D Auditory Haptics: Geiger counter-style clicks during rolls USB-C Rechargeable: 25-30+ hour battery life Educational: Learn about nixie tube circuits and quantum random number generation Choose Your Enclosure: Laser-Cut Basswood - Warm, natural wood grain with steampunk aesthetic Clear Acrylic - Crystal-clear enclosure that reveals your quantum circuit, nixie tubes, and components. Laser cut components shipped with protective paper, but that is removed prior to final assembly.
