Fresh hacks every day
We’ve got to say it… these tubular bells sound awful! They don’t really have a tight pitch center so they sound really out of tune to us. But we think that’s the failing of the instrument itself and not the work which [Tolaemon] did to automate the instrument.
There are three main parts to his project. The first, which … Read the rest
We admit that this project doesn’t have very many details available, but it was just too neat for us to pass up. It’s a small linear motor which [ligonapProduktion] built after seeing a very brief description of a commercially available version.
The video after the break shows him testing the motor. In this screenshot he’s holding the center shaft while … Read the rest
[Paul Mandel] just finished building this knock box project. It’s a familiar concept that uses a solenoid to tap on the side of the box. The Arduino driven setup monitors vibrations on the lid. When you knock on the box, it records the pattern and plays it back using the solenoid.
He was inspired by a knock-detecting door lock… Read the rest

Unfortunately you can’t play both instruments at once so he set out to automate the keyboard. What you see here is a fully working version, but he … Read the rest
[Lou's] latest tutorial details the process of turning an electric stapler into a coil gun. The stapler is the expensive part, but the rest is pretty simple. He used PVC pipe and a handful of fittings along with a few supplies you probably have kicking around your shop.
It’s surprising how perfect the Bostitch stapler (from which the parts … Read the rest
The vegetables will be alive when [Dillon Nichols] returns from vacation thanks to this automatic watering controller that he built. This is the second iteration of the project, and deals mainly with replacing the electronics and UI of the controller itself. He detailed the hardware used for watering in a previous post. He plumbed in a solenoid valve with a … Read the rest
[Sage Spate] wasn’t happy with the boring flavors of orange, blue, or red sports drinks. He decided to mix it up by building this flavor-mixing drink dispenser.
He modified the caps for each bottle to work with an air-pressure system. This way the bottles themselves serve as the reservoir and can easily be replaced when empty. Each cap has … Read the rest
