At first glance you would think this is the real thing, but [Kevin] built this railroad crossing signal from parts you can find at the home store. We keep seeing traffic lights used as web-connected signaling devices. This would be right at home for that type of setup, but [Kevin] built it with railroad enthusiasts [...]

For his senior design project at Swarthmore College, [Julian] decided to build a metalworking equivalent to the RepRap. [Julian]‘s final project is a self-replicating milling machine, and hopefully giving some serious metalworking power to all the makers with CNC routers and RepRaps out there. At first glance, [Julian]‘s mill doesn’t look like something you would find [...]

Here’s a floppy drive which is being used as an audio sampler. At first glance we thought this was another offering which drives the stepper motor at a specific frequency to generate that characteristic sound at a target pitch. But that’s not what’s happening at all. The floppy is actually being used as a storage [...]

[Rajendra] got tired of building the same basic circuits time and again on the breadboard. He decided to build some simple, modular circuits on protoboard and make them easy to interface with the breadboard. As you can see, he ended up with seven modules that make prototyping faster and easier. At first glance some might [...]

[Eric] and the crew over at The Tech Junkies, just put the finishing touches on a pretty powerful robot that they call “Mantis”. The six wheel, chain-driven robot is pretty impressive at first glance. The robot is centered around a Netduino, which controls four 60 amp speed controllers. The speed controllers are tasked with driving [...]

[Niklas Roy] sent in a project he just completed called PING! Augmented Pixel. At first glance the entire build is just a plain jane retro video game stuffed into an ATmega8 but looks can be deceiving. The video game is actually an augmented reality device that inserts a pixel into a video feed. The bouncing [...]

We’re always fascinated by flying drones around here, and this latest creation by Japan’s Ministry of Defense is no exception. The spherical drone, which looks far simpler than this drone we saw several months back, looks pretty benign at first glance. Once it starts moving however, you can see just how slick it is. Reports [...]

The IEE clock looks somewhat un remarkable at first glance. Upon closer inspection though, you’ll find out that there are 12 light bulbs crammed in there for each digit. The bulbs sit behind a curved lens with the numerals on it. When the appropriate one is lit, it projects the number on the front of [...]
