10 minute snooze
Integrated boost converter so it can run off of standard DC wall adapters, works in any country regardless of mains power
Great for desk or night table use, the clock measures 4.9″ x 2.9″ x 1.3″ (12.5cm x 7.4cm x 3.3cm)
Completely open source hardware and software, ready to be hacked and modded!
Complete kit comes with a 110/220V 9VDC power supply (a $1 plug adapter from your local hardware store will allow it to be used worldwide), all components including PCB, vacuum fluorescent tube, backup battery and a clear acrylic enclosure. Assembly is required! This kit is made of through-hole components but is best built by someone with previous soldering experience as there are many parts and steps.
For assembly instructions, user manual, code, schematics, and more, please visit the Ice Tube Clock webpage!
**Note: This kit is super popular, and the supply of tubes is harder to get. Thus the price is going to increase slowly but surely until the tubes are unavailable & the kit is discontinued. Thanks for your understanding!

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.

Wonderful kit! It is every bit as good as the Heathkits that I use to build years ago! Excellent instructions and very nice design. I did have an issue with the one bolt that fastens to the VFD tube side of the PCB. The bolt is too large and could possibly short R3 to the push button frame and a couple VFD pins. I used a small nylon spacer in place of the bolt on this end for safe measure. Super fun kit and would recommend this project for anyone interested in electronics!
