Steampunk Vacuum Tube Display (USB)

USB Steampunk Tube Display This project brings together electronics, programming, 3D printing, and artistic painting to create something unique you can display on your desk. The device detects sound and turns on an LED that illuminates the vacuum tube temporarily. Colors shift over time. Place it next to a music speaker for a cool light effect as the tube dances to music. Check it out in action on YouTube: https://youtu.be/V9su3MfrOe0 Bill of Materials: Qty 1 ($1-$33) Vacuum Tube 8 Pin (does not need to be operational) I used this burned-out tube from a tube amplifier, but any 8 pin vacuum tube should work after removing the plastic center pin. Note: You can also find old/used tubes for sale on eBay.
