This is our first clock kit design, made with a retro Russian display tube!
- Cool glowing blue tube with 8 digits, PM dot and alarm on/off indicator
- Adjustable brightness
- Alarm with volume adjust
- Precision watch crystal keeps time with under 20ppm (0.0002%) error (< 2 seconds a day)
- Clear acrylic enclosure protects clock from you and you from clock
- Battery backup will let the clock keep the time for up to 2 weeks without power
- Selectable 12h or 24h display
- Displays day and date on button press
- 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.
