Fresh hacks every day
As you already know, we'll be attending CES this year. We're still looking for ideas on what you, our loyal readers, want to see. We've gotten some good feedback, and came up with some ideas of our own. Keep sending in your ideas. Remember, it doesn't even have to do with CES. Are there any hacker groups in Vegas that we could meet with? Any locations of interest? Let us know. So far, we have … [Read more...]
[Nophead] started the year off by successfully extruding acrylic using a RepRap machine. The problem when working with this material is that when the hot ooze hits the cold air the printed material tends to warp, badly. [Nophead] raised the ambient air temperature around the part being extruded by replacing the bed of the RepRap machine with a heated aluminum plate. We took at look at his build … [Read more...]
What you see above is a generator that converts heat to electricity. [Reukpower's] thermoelectric lamp is one of those hacks that makes you scratch your head even though you understand why it should work. The heart of the system uses a Peltier cool, just like the thermoelectric solar generator. When there is a temperature differential from one side of the Peltier to the other a small current is … [Read more...]
At first glance we thought this record player had been modified to serve as a persistence of vision device. The device looks very much like an unmodified turntable but it has four tracks worth of display space in it. The messages are actually glowing and don't depend on a POV effect. Instead, the table has been coated with phosphorescent paint that will glow after being exposed to bright light. … [Read more...]
[Atlantageek] sent in a missile launcher project that he threw together. For Christmas he received a Chumby One and a ThinkGeek USB Rocket Launcher as gifts (lucky dog). Neither of these toys are "played with" in the traditional sense as much as they become centerpieces of your next hack. In that spirit, [Atlantageek] immediately wrote a widget to control the launcher via the Chumby. The side … [Read more...]
[Rockwell] sent us an update on his traffic light hacking. Dedicated readers will remember seeing this legally attained traffic signal controlled through a parallel port from back in 2005. The new update swaps the old port for USB and adds several autonomous functions which are demonstrated in the clip after the break. The update includes a nice UI and some notifications for things like email, … [Read more...]
A couple of readers weren't too thrilled when the winners were announced a while back for the Nokia N900 competition. And to be honest, we even wondered on some ideas (like what does skateboarding have to do with hacking?) However, The teams have been hard at work and a picture video is starting to form for each. Check after the break for some video recaps. [Thanks Matt] … [Read more...]
