I had a great time building the Edo-Style clock kit from Gakken, and was amazed at its accuracy over several months of use. The kit is well designed, durable, and fun. The included picture-based directions are easy to follow, even if you don’t know Japanese, but if you plan to make one, you can also refer […]

Nixie tubes, beautiful relics of early computing, display their numerals with a quivery orange glow. Peter J. Jensen makes Nixie tube clock kits, and it was a joy to put one of them together, thanks to the clear step-by-step instructions and parts envelopes labeled with corresponding numbers. Jensen designed the clock and circuit board himself, […]

Need to add a clock function to your next Arduino project? This Real Time Clock (RTC) breakout board kit is your answer. Based on a DS1307 RTC and equipped with an onboard battery and crystal, this kit is simple to solder together, works well, and is easy to use thanks to Adafruit’s online documentation. It’s […]

Old-fashioned Nixie tubes are beautiful, but driving them in a circuit can be complicated since they often require voltages as high as 250V DC. The ArduiNIX board for Arduino makes it easy to add standard clock functions to your next project. Just be sure to design an enclosure that will keep those high voltages safe. I […]

Alternative time-telling devices are compelling, but only if they’re easy to read. Building a kit can be satisfying, but only if it leaves room for creativity. The Chronulator clock kit fits the bill on both counts. Solder it together, and you’ve got a microcontroller-based clock that converts time to current, displaying hours and minutes on […]
