Jeff has a new clock that he shared with the world on the DWF.nu forum. It is a new design for a nixie watch based on Burroughs B4998 tubes. It will include a rechargeable lithium ion which should last about 3 months. The device is 41mm wide, 19mm tall, 32mm deep and weighs about 28 grams (not including enclosure). Lastly, it will include a changing cradle for the watch.
This device also has some other uncommon features. The watch is activated by a wrist snap-shake using a magnetized ball rolling in a steel barrel. Any unintended activations are kept to a minimum by an R/C timer circuit. Setting the time is done with a rod magnet which activates a micro reed switches placed on each end of the logic section. All of this is built using CMOS logic components; just like the original LED watches of the 70’s. “I didn’t cheat and use a microprocessor. Although I did use seven very small TSSOP packaged IC’s.”
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.
