Fresh hacks every day
[Martin Raynsford] figured out a way to sneak some learning into a fun package. He did such a good job the test subjects didn't even know they were teaching themselves just a tiny bit of CNC programming. The apparatus above is a marble maze, but instead of building walls [Martin] simply etched a pattern on the playing field. The marble is a ball bearing which moves through the maze using a … [Read more...]
For as many garage and workshop videos we feature here on Hackaday, we're surprised we haven't seen this sooner. [Todd] makes a bunch of videos in his garage shop, but using a tripod is a pain; he's always tripping over his camera setup and it is just generally in the way all the time. His solution was to mount his camera to an overhead gantry, using the unused tracks for his garage door to … [Read more...]
[Jerry] missed the laser cutters he had been using at the local TechShop. It closed down and after seeing some hardware in a surplus store he decided to build a laser cutter to call his own. You won't be disappointed by his build log. It's got a ton of hi-res images and plenty of explanation. Often, cost is the key consideration in these types of builds. [Jerry] spent a little more than … [Read more...]
The Harford Hackerspace in Baltimore, Maryland just went public with the zen garden they built for the Red Bull Creation contest. It's a CNC creation that will help ease your frustration with that DIY 3d printer that you just can't seem to get calibrated correctly. On the hardware side the base of the machine serves as a sandbox. Finding the correct grain size of the medium was one of the more … [Read more...]
[Patrick McCabe] enjoys the challenge of playing chess against the computer but he wasn't satisfied with the flat experience of on-screen gaming. No problem, he just built his own gantry-style chess robot that he can play against. Don't be confused, he still doesn't have to touch the pieces, but instead uses the dedicated control board seen on the left of the image above. The robotic arm that is … [Read more...]
Everyone's familiar with the quarter gobbling crane games. More often than not there's a child nearby begging a parent for more quarters so they can try their hand at the toy-snatching claw. [Marc.Cryan] put his quarters to a better use by building a home version of the crane game. [Marc] installed a gantry in an archway of his house. The crane trolley rides on this gantry and uses a spool to … [Read more...]
An exhibition just wrapping up at the Russian Frost Farmers Gallery in New Zealand presented an interactive artwork hack. Called the Radio Assisted Drawing Device (R.A.D.D), it is a plotter that mounts on the wall. It isn't computer controlled, but rather relies on a remote control with two sticks to move the plotter Etch-a-Sketch style. A clear gantry mounts vertically and travels along the … [Read more...]
