Fresh hacks every day
Even though it’s a bit late for April Fool’s jokes, [Ameres] wrote in to share a project guaranteed to catch your friends (or enemies) by surprise. Like us, he had some old CD-ROM drives sitting around and thought that there must be some way to put them to good use. He gutted one, saving the laser’s carrier unit for use as his mechanical trigger. He placed the unit above a doorway, … [Read more...]
[Norman] put together a rather impressive 22,500 uF capacitor bank. In addition to find things to torture with the strong magnetic field generated by a sudden discharge, he'd like to measure the current pushed from the device. He's found a way to do this using a digital storage oscilloscope. To protect the oscilloscope [Norman] built his own interface box that includes a 50x voltage divider, and … [Read more...]
[Scott] was looking to source some LCD screens for an upcoming project, and was considering buying them from SparkFun. While the Nokia panels they sell are not expensive, they aren't necessarily the cheapest option either - especially when building in volume. He searched around for something he could use instead, and settled on Blackberry screens. Old Blackberry models were even more durable … [Read more...]
[John W. Linville] wrote a digital video player for the Tandy Color Computer (aka TRS-80). The decades-old hardware performs quite well considering the limited resource he had to work with. This is the second iteration of his player, and can be seen after the break playing a promo video for CoCoFEST 2011 where he'll show it off in person. In the most recent thread post (at the time of writing) … [Read more...]
While the Kinect is great at tracking gross body movements and discerning what part of a person's skeleton is moving in front of the camera, the device most definitely has its shortfalls. For instance, facial recognition is quite limited, and we're guessing that it couldn't easily track an individual's eye throughout the room. No, for tracking like that, you would need something far more … [Read more...]
[Trav] was pondering virtual reality and decided it was no longer all that it was cracked up to be, so he created an experience in what he calls "Remote Reality". While we have seen many installations over the years that allow people to remotely interact with objects across the globe, his Orbduino project consists of more than simply toggling lights on and off (though he'll let you do that … [Read more...]
Spring is upon us and Instructables user [Mischka] decided it was a good idea to combine two flavors we never considered putting together: The Easter Bunny and the A-Team. He decided to build the egg as an Easter gift for his brother, who is a huge fan of the A-Team. He found a slightly larger than normal plastic egg, and proceeded to paint the shell white, adding a printed picture of Mr. T … [Read more...]
