This Word Clock Has Dirty Alphanumeric Mouth

Clocks which use words to tell the time in place of numbers are an increasingly popular hacker project, but we have to admit that before seeing this gorgeous clock from [Mitch Feig], we didn’t realize how badly we wanted to see one that could curse like a sailor.

But don’t …read more

Stack Those Boards For An Extra-Special Backlit LED Effect

By now most of us should be used to backlit LEDs, in which a bare board with no copper or soldermask as an LED mounted on its reverse side to shine through as if with a diffuser. [Wim Van Gool] has created such an LED display with a twist, instead …read more

This LED Cube Is One Heck Of An ICEBreaker

Like the tastes of the makers that build them, LED cubes come in all shapes and sizes. From the simplest 3x3x3 microcontroller test, to fancier bespoke installations, they’re a great way to learn a bunch of useful embedded techniques and show off at the same time. [kbob] has done exactly …read more

Faux-Neon Sign Says What?, Auf Deutsch

To a speaker of English, a sign asking ‘Was?” may not make much sense. In German, however, the question is a more thought-provoking “What?” That’s exactly the point of this faux-neon sign created by [noniq]. The sign uses silicone-enclosed “neon-like” LED strips to spell out the question for all to …read more

Giant LED Display is 1200 Balls to the Wall

When you’re going to build something big, it’s often a good idea to start small and work out the bugs first. That’s what [bitluni] did with his massive 1200-pixel LED video wall, which he unveiled at Maker Faire Hanover recently.

We covered his prototype a while back, a mere 300 …read more

Fail Of The Week: How Not To Light Pipe

You’d think that something made out of glass and epoxy would transmit a decent amount of light. Unfortunately for [Jeremy Ruhland], it turns out that FR4 is not great light pipe material, at least in one dimension.

The backstory on this has to do with #badgelife, where it has become …read more

LED Driver Board Could Be Your Ticket To FPGA Development

Microcontrollers are a great way to learn about developing for embedded systems. However, once you outgrow their capabilities, FPGAs bring muscle that’s hard for even the fastest-clocked micros to match. If you’re doing anything with high-speed signals, loads of RAM, or something that requires lots of parallel calculation, you can’t …read more

A Farewell To YouTube Sub Counters Set To Break With API Change

Of all the things you never would have guessed you’d need just ten years ago, a YouTube subscriber counter would probably rank highly. You would have guessed that the little hits of dopamine accompanying each tick upward of a number would be so addictive?

As it turns out, lots of …read more

Driving P5 Panels With A Raspberry Pi

Building displays out of LEDs can be fun, but quickly becomes tedious as the pixel count increases. At this point, it’s worthwhile investing in off-the-shelf panels that have everything pre-soldered and ready to go. [Tom Hammond] wanted to run a P5 panel, and put a Raspberry Pi to work to …read more
