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 … Read the rest
We agree with [Mário Saleiro] that the motors from a car’s power windows make for a fantastic high-torque solution to your next project. If you have a you-pick junkyard in your town they’ll be dirt cheap after you put in a bit of time to find and removing the parts from the yard. But you’ll probably want to add a … Read the rest

The thirty-five minute video walks through every part of the process which we originally learned about … Read the rest

It does an amazing job of automating the hardest parts of hand assembly, while relying on human dexterity to achieve the hardest parts of automation. It’s a semiautomatic pick and place machine driven by an Arduino and controlled by an Android tablet.
The machine is built in … Read the rest

The build is delightful, and you can’t move on to the next feature until you watch it play a game in the clip after the break. The game … Read the rest
We just got an ergonomic keyboard for the first time and absolutely love it. But the look of this keyboard hack has us second guessing ourselves. [Will Pretend] pulled off an absolutely stunning wooden retrofit for his USB keyboard. Be warned, his project log includes 175 photos, and most of them have captions.
He started off by taking apart … Read the rest
