Matrix of Resistors Forms the Hot Hands Behind This Thermochromic Analog Clock

If you’re going to ditch work, you might as well go big. A 1,024-pixel thermochromic analog clock is probably on the high side of what most people would try, but apparently [Daniel Valuch] really didn’t want to go to work that day.

The idea here is simple: heat up a …read more

Is that an ESP32 on Your Wrist?

What could you do with a dual-core 240 MHz ESP32 that supports Arduino-style programming, with 16 MB of flash, 8 MB of PSRAM, and 520 k of RAM? Oh, let’s throw in a touchscreen, an accelerometer, Wifi, and Bluetooth. Besides that, it fits on your wrist and can show the …read more

LED Matrix Takes You Down To Nixieland

It’s said that imitation is the sincerest form of flattery. Sure, there are some who might simply sugarcoat blatant plagiarism with fancy quotes, but there are still cases that come from well-intended, genuine admiration. The Nixie tube with its ember-like glow is a component that definitely gets a lot of …read more

Clear Some Space and Build a Cosmo Clock

Like many of us, [Artistikk] is inspired by astronauts and space travel in general. To keep the inspiration coming, he made the Cosmo Clock — a sleek little clock that changes color whenever an astronaut is launched into space.

As awesome as space is, we’re inspired by the amount of …read more

Beautiful Free-Form LED Clock Recreates 20-Year-Old Weekend Project

Here at Hackaday, we love a good clock project. And if it’s an artistically executed freeform sculpture, even better. But tell us that it’s also a new spin on a classic project from two decades ago, and we’re over the moon for it. Case in point: [Paul Gallagher’s] beautiful recreation …read more

LED Clock Strips Time Down to Pulses of Light

Nietzsche said (essentially) that time is a flat circle — we are doomed to repeat history whether we remember it or not. This is a stark and sobering thought for sure, but it’s bound to dissipate the longer you look at [andrei.erdei]’s literal realization of time as a flat circle. …read more

Planetary Gears Tell Time In This Ornamental Clock

A clock is perhaps one of the the most popular projects among makers. Most designs we see are purely electronic and do not bother with the often more complicated mechanical part. Instructables user [Looman_projects] though was not afraid of calculating gear ratios and tooth counts for his planetary gear clock. …read more

Seven-Segment Single-Steps Through the Time

Have you ever looked at the time, and then had to look again because it just didn’t register? This phenomenon seems more prevalent with phone timepieces, but it’s been known to happen with standard wall clocks, too. This latest offering in a stream of unusual clocks fashioned by [mircemk] solves …read more

Tell Time like It’s 1960 With This All-Transistor Digital Clock

When you’ve got time on your hands, doing something the hard way can be therapeutic. Not that the present situation and the abundance of free time that many are experiencing has anything to do with [Leo Fernekes] all-transistor digital clock build, which he started a year ago with his students. …read more
