How cool is this? This is an Arduino project dubbed The Worduino, from the excellent WyoInnovations blog.
LEDs positioned behind the platter will shine through the cut out numbers in the platter, with a custom controller circuit automatically coordinating the blinking LEDs, to illuminate the appropriate number window in the platter when it is lined up.
Yes, he could stretch to put on his glasses and then clock the time (waking himself up in the process) or he could – as an ingenious inventor – create a device for displaying on the ceiling how many hours and minutes remain for sleep, using a Lego-housed Arduino-based laser device.
Long term readers of this blog know we have featured Nixie tube clocks a couple of times (see here and here), but this is the first one for a wrist watch. And worn by Apple co-founder Steve Wozniak, no less.
Wow! What a strange but clever idea: a “Bulbdial clock” – applying the principles of a sundial to (adjustable) electric light.
Browsing through the Gadget Freak archives, I noticed how often clcoks and time reoccur. How about this sample of seven, in reverse chronologal order?
Based around LED cluster modules and a microcontroller, the circuit drives F1-style gantry race start lights. Who wouldn’t want to be the race controller, with their finger on the starting switch?
Back in the days of the Berlin Wall, these Nixie tubes were manufactured by a now long-forgotten company. Fast forward to the twenty-first century, and Hans Summers found them stocked by an antique electronics part company.
