Fresh hacks every day
[Martijn] is showing off his new clock which he calls a Light Spectrum Clock. We like to look of it, using RGB LEDs in five squares that remind us of some of those LED coffee table builds. From left to right this shows the week, day, hour, minute, and second. Simple, right?
We had to smile a little bit … Read the rest
[Josh] and his lab partner [Eric] needed a final project for their Embedded Systems Design class, and thought that designing an Arduino shield would be a cool idea. They noticed that there are plenty of ways to get an Arduino to keep time, though none that they knew of utilized WWVB (Atomic Time) signals directly.
[Erik] wrote in letting us know that he just completed development of the Bobuino, a Arduino based on an ATmega1284. That chip is nice and beefy, most notably for having 16 KB of SRAM but it also boasts 4 KB of EEPROM, and 128 KB of program memory.
But the upgraded chip isn’t the only thing that it brings … Read the rest
[Giorgos Lazaridis] just finished building a simple clock on a breadboard. It uses a common real time clock chip, the DS1307. This is less expensive that its full-featured older brother, the DS3232. The difference between the two is that the 1307 requires an external 32.768 kHz crystal and it is not temperature compensated. This means it will not … Read the rest
[Mure] wrote in to let us know he has put the finishing touches on the second iteration of his Warm Tube Nixie clock. We featured his original creation here last year, and while many things remain the same, he has still found a few things that he was able to improve on.
The first notable feature is the … Read the rest
Like many electronics hobbyists, [Pete] found that he had an overwhelming desire to build a clock for himself. He didn’t want to stick a discrete real time clock IC into a box and call it a day, so he opted to construct his own around a microcontroller instead.
After researching the specs on a few RTC ICs, he defined some … Read the rest
[Jarek Lupinski] is at it again, this time building a clock using 15 Nixie tubes. Just look at the time…. wait, how do you read this now? It’s not seconds since the epoch, but an homage to a very expensive New York City art piece. [Jarek] took his inspiration from the Metronome art installation in Union Square.
We hadn’t … Read the rest
