Tracking cicadas with Radiolab and an Arduino

Cicadia

Once every 17 years, a population of cicadas ranging from Connecticut to the Appalachian highlands of North Carolina emerges to annoy everyone within earshot. The last time east coasters saw this brood was in 1996, making 2013 yet another year of annoying insect pests. The only question is, when will we start to see this year’s cicada brood?

Radiolab, the … Read the rest

Vine app hack on iPhone makes time-lapse movies

time-lapse-with-smashed-iphone

The Vine app is all the rage these days. It lets you shoot six-second videos on your iPhone and easily post them on the Internet. The problem is that [Sean Hodgins] doesn’t find the time limit to be useful for traditional video. But you can cram a lot more info into a half-dozen seconds if you make it a time-lapse … Read the rest

Scooterputer, the all-in-one scooter computer

ScootDisplay-2

We’ve seen a fair share of carputer builds involving a Raspberry Pi in the last few months, but even the power of a Raspi can’t compete with the awesomeness of this Arduino-powered scooterputer.

Like all awesome projects, this build is the product of a massive case of feature creep. Initially, [Kurt] only wanted a voltage monitor for his battery. … Read the rest

North Street Labs try to spice up a game of Tic-Tac-Toe

The team at North Street Labs really went all out with this Tic-Tack-Toe stomp box. At its most basic it’s a blinky version of the simple two-player game. But there’s always some added appeal when you make large manifestations of normally small items; the 10x Arduino is a good example of this. The project is NSL’s […]

[Martin Raynsford] figured out a way to sneak some learning into a fun package. He did such a good job the test subjects didn’t even know they were teaching themselves just a tiny bit of CNC programming. The apparatus above is a marble maze, but instead of building walls [Martin] simply etched a pattern on […]

Everything you need to know to make a Laser engraver from scrap

Check out the Einstein head which [Sebastian Müller] etched on the cover of his calculator using a laser engraver he made from scratch. We think he did a great job with the build, but we’re even more impressed with the work he put into sharing the techniques he used to salvage and repurpose all the components. […]

AM tube radio restored and given MP3 playback too

This AM radio looks a bit like it did coming out of the factory. But there are a lot of changes under the hood and that faceplate is a completely new addition. The project really is a restoration with some augmentation and [Michael Ross] did a great job of documenting the project. The Kenyon radio …

Scratch-built 3D printer shows rock-solid performance

These days it’s super-easy (not super-cheap) to go out and buy a 3D printer. But if you’ve got the mad skills like [Mario Lukas] maybe you can build a 3D print using a bunch of scavenged parts (translated). He’s published six posts on the build, and put together an overview video which you can watch after the …

Glowing Easter eggs more fun than a dye job

This is a project to keep in mind for the kids next Easter. It uses electronics to light up your eggs instead of dying them (translated). The project still has one foot in the old tradition as it starts by blowing out the eggs. The larger hole on the bottom, which was used to evacuate the …
