Fresh hacks every day
Electronics are undoubtedly the basis for our modern society. Leaving out transistor-based devices, and a mechanical clock would be one of the most intricate devices man has come up with. As a Mechanical Engineer, I thought it would be a fun challenge to design and build my own gear-driven clock.
Because clocks have obviously been invented, I wouldn’t be starting … Read the rest
Still trying to solidify that reputation as the office Grinch? This project will let everyone know you’re a complete jerk in no time. It’s called the 8-bit Annoying Person Remover. It detects when someone enters your office at which point it starts to play the Super Mario Bros. theme song while the display counts down 400 seconds. Just like … Read the rest
With the massive response and blog cred from his QR Code clock, [ch00f] felt it was time to step up his game and update his design to a proper commercial product. His new QR clock is bigger, brighter, cheaper, and in every way better than the old version, but these improvements came at a cost.
The LED matrices [ch00f] … Read the rest
The location clock found in the Harry Potter books makes for a really fun hack. Of course there’s no magic involved, just a set of hardware to monitor your phone’s GPS and a clock face to display it.
[Alastair Barber] finished building the clock at the end of last year as a Christmas gift. The display seen above uses … Read the rest
The motivation industry turns out these type of award trinkets by the millions. Here’s a way to actually put the thing to use. Instead of displaying time, the clock dial serves as the readout of a voltage meter.
When we first saw this post we assumed that the hack used some type of coil injection to drive the hands… Read the rest
An awful lot of microcontroller projects use timers to repeat an action every few minutes, hours, or days. While these timers can be as accurate as a cheap digital wrist watch, there are times when you need a microcontroller’s timer to measure exactly, losing no more than a few milliseconds a day. It’s not very hard to get a … Read the rest
Sure, it’s time to get the countdown clocks ready to ring in the new year, but why limit it to just one night? If you end up building a six-foot digital display you can count down trivial events; like the remaining seconds of freedom before you have to pimp yourself out in that drab cubicle.
This seven-segment display is homemade … Read the rest
