TubeCube – a VFD tube MiniBadge add-on #BadgeLife #Tubes #Displays @Hamster @Hackaday

Hackaday highlights @Hamster’s TubeCube tube segment driver.

The TubeCube is built to fit the MiniBadge badge addon standard, which is primarily used to host modules on the SAINTCON conference badge. A single TubeCube hosts a VFD tube, hardware to provide a 70 V supply, and a microcontroller for communication and control. Each TubeCube is designed to accept ASCII characters via UART to display on it’s display, but they can also be chained together for even more excitement. We’re not sure how [hamster] would be able to physically wear the beast in the video above, but if he can find a way, they all work together. If you’re interested in seeing the dead simple UART communication scheme take a look at this file.

Hamster’s GitHub repository has a schematic and sources, which should be enough to build a small tube driver of your own.

8-6-2021 (August 6, 2021) is the Snakiest day of the year and it’s also this year’s CircuitPython Day! The day highlights all things CircuitPython and Python on Hardware. See you there!

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
