Fresh hacks every day
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 this one in particular stands out as being quite ambitious. [Jaimie] is building a giant hexapodal … [Read more...]
[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 you can return to normal function. When finished, you'll have a multimeter that will … [Read more...]
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 are several other hardware options covered as well. The firmware makes use of the serprog-duino … [Read more...]
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, helping to differentiate between letters that have … [Read more...]
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 Carnegie Mellon University has made with WonkaBot, their chocolate extrusion printer. Unlike … [Read 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 the water is filled with bubbles to add some depth to the presentation. There is … [Read more...]
[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 for this purpose. The system does not actually use Radar for tracking. … [Read more...]
