Fresh hacks every day
If you own an oscilloscope, sooner or later the urge to see something other than signals on the screen will strike. Some people ignore the urge and go about their normal business while others give in, spending hours carefully crafting images, games, and more. The process is time consuming and tricky as our own [Kevin Dady] discovered, but rewards come in the form of geek cred and are hard to pass … [Read more...]
Dig out an old cell phone, hit the dollar store for some plastic recorders, and build this sound controlled snake game for your next party. The project will be a snap for those comfortable working with microcontrollers, and a great learning experience if you're looking to try your first Arduino project. [László] and his friend call the project the Snake Charmer. As shown in the clip after the … [Read more...]
Skills are all that's needed to solve a problem. Take this four-wheeled robot as an example. [Michal Zalewski] wanted it to be omnidirectional but wasn't very satisfied with the concept of mecanum wheels and the like. So he designed a chassis with wheels at each corner that can pivot as one to change orientation. The image may look like a rendering at first glance, but this is actually the … [Read more...]
[Unihopper] built this sliding camera mount to add some motion to his freestyle unicycle videos. It's extremely simple, but still pulls off a pretty nice effect as you can see in the clip after the break. The image above shows the mount without a camera attached. You can see the threaded peg on the block in the foreground which is used for that purpose. Felt has been wrapped around the base … [Read more...]
While we're reluctant to say it for fear of being misinterpreted, the new liquid fuel rocket engine being built by Copenhagen Suborbitals is one of the most impressive, daring, and nearly the sexiest machine we've ever seen. Although the engine hasn't been fired yet, [Peter Madsen], Chief launch vehicle designer at Copenhagen Suborbitals, gives an amazing 18-minute-long rundown of the function … [Read more...]
This Lego Tachikoma drives and walks just like in the TV program. You simply must take a peek at the video after the break. We've watched it several times and don't think there's any editing magic going on. But the movements are so intriguing part of us thinks there's something fishy about it. Each leg has a wheel that is connected to a motor via chain drive. But the little guy isn't … [Read more...]
It seems that more often than not, [Steffest] finds himself inspired to rock out on his guitar without a percussion section to back him up. Like any enterprising hacker/musician would be wont to do, he built a robotic drummer to join in when he got the urge to play. His DrummerBot is driven using an Arduino, which is tasked with controlling the 8 servo motors that the bot has at its disposal. … [Read more...]
