Fresh hacks every day
The latest robot out of Nolebotic is Al.I.S.E, or Aluminum, Infrared Scanning Entity. Don't let the name fool you, its a pretty simple take on the classic hexapod walking platform using a crank arm and leavers made into the legs. The body of the robot is made out of aluminum which is pretty easy to work with at home, lightweight, and sturdy. Bolted to the body are a pair of beefy gear head … [Read more...]
I think we can all agree, there are few things that go better with hacking everything than beer. [Tom] has taken his love for beer and building things, fusing them together in a DIY kegerator. Using an off the shelf mini fridge and some easy to find beer serving components, he walks us through the conversion step by step. When everything is said and done, the kegerator should hold two 5-gallon … [Read more...]
We received several fantastic entries. We laughed, we cried, we stared at our monitors in confusion, it was fantastic. Now we're here to announce the winners of the Santa-Pede contest. If you recall, the rules were pretty simple. Aquire a dancing santa (or other holiday dancing annoying toy thingy in the same fashion), tear it apart, build something that walks out of the pieces. We were aware … [Read more...]
[Bob] has been busy lately putting the finishing touches on three different projects that he plans on entering into the 555 Design Contest. His first entry is a low-power H-bridge, which can be used to drive small servos. While he admits that it is a bit odd to build use a 555 timer to construct an H-bridge, they are cheap and plentiful enough to justify their use. Check out the video below to … [Read more...]
We were sent [Dr. Offset’s] most recent project, a kid’s toy that is half sculpture/half noisemaker, but 100% cool. The device uses several 555 Timers and is his entry into the 555 Design Contest, which wraps up in just a few days. To really enjoy his creation, you need to suspend disbelief for a moment, and indulge the space fantasy he creates. In other words, let yourself be a kid again, if … [Read more...]
This 2-bit adder was a lot of work to build. It uses a total of thirty-six 555 timers and it does have the option of adding or subtracting numbers. It's a rather unorthodox use of the part, depending more on the chip as an inverter and taking advantage of the fact that there's an NPN transistor built into it. [cpu86] did use some PNP transistors to give him the ability to turn off some of the … [Read more...]
All this talk about 555 timers is causing projects to pop out of the woodwork like this one that reverse engineers a shopping cart security mechanism. The wheel seen above listens for a particular magnetic signal and when encountered it locks down the yellow cowl, preventing the wheel from touching the ground and making the cart very hard to move. [Nolan Blender] acquired one of these wheels … [Read more...]
