Warning, this may be a duplicate post. We all agree we’ve seen this before, but can’t find it in our archive. If it is, sorry. If it isn’t enjoy one of the most awesome projects we’ve seen in a long time. Meet [Jaimie Mantzel] an eccentric, and very hyper, individual. He’s done many projects, but …

Upgrading a digital multimeter to tell the temperature
[Rajendra] tipped us off to this really slick hack he’s done to allow his multimeter to tell the ambient temperature. He’s basically measuring the output of an LM35 temp sensor that he has mounted in the case. The circuit is extremely simple and only requires the sensor, a couple resistors, and a switch so that …
Arduino Uno BIOS flasher
We’ve seen the Arduino used to flash BIOS chips several times now. But these hacks are almost always the result of a bad flash. This time around [GNUtoo] is interested in putting a tool in your hands which can be used to flash Coreboot to your motherboard. His offering uses the Arduino Uno, but there …
Sign and speak glove
This wire covered glove is capable of turning your hand gestures to speech, and it does so wirelessly. The wide range of sensors include nine flex sensors, four contact sensors, and an accelerometer. The flex sensors do most of the work, monitoring the alignment of the wearer’s finger joints. The contact sensors augment the flex sensor data, …
Chocolate extrusion printer is halfway to making s’mores
Chocolate has got to be one of the worst choices as a printing medium. It’s extremely fussy when it comes to melting point, and even in the right state the flow of the material is not going to play nicely with high-resolution designs. With this in mind, we applaud the progress the student team from …
Huge water and light VU meter plus more
This is the senior design project for a group at the University of Vermont. It’s a wet, bubbly, blinky, interactive thing. Each column is a clear tube filled with water, with a string of fully addressable RGB LEDs suspended in the center. In idle mode, the lights scroll through a series of interesting patterns while …
Automatic airplane tracking; what radar-systems engineers do for kicks
[G. Eric Rogers] is a radar-systems engineer who just happens to live within sight of the aircraft approach path for the local airport. We wonder if that was one of the criteria when looking for a home? Naturally, he wanted his own home-based system for tracking the airplanes. He ended up repurposing a motorized telescope …
DIWire Bender makes nearly any shape imaginable
The people over at Pensa posted an awesome CNC wire bender on their blog. Robotic wire benders are common industrial machine that are very fun to watch. These machines can turn out custom wire-bent parts or sculptures in a matter of seconds. The Pensa team’s “DIWire Bender” might not be as fast as the big boys, …
Reaching out to a touch screen with a microcontroller
We love capacitive touch screens. They’re much more robust than resistive touch screens and if the UI is programmed well they produce a great user experience. But getting your electronics project to interact with one is a bit tough. [RobB] has been experimenting in that area, and managed to build a simple touchscreen actuator for microcontroller …
Creating a multimedia elevator ride
[Ben Peoples] works in theatrical electronics. Sounds like fun, and here’s an example of the kind of stuff he does. We’re not sure what event this installation was used for, but if the elevator ride needed something flashy just think of what the party room must have looked like. These HDTV screens on the ceiling …
