Fresh hacks every day
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
We stumbled onto [Staci's] videos a while ago when we posted this big tesla gun. While it wasn’t the first portable coil we had seen, it was certainly an impressive implementation. In the comments we found [Staci] had already been making these for a while. Hers were big and small, had awesome modulation, and looked freaking cool too.
It … 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
Despite the obvious use of a lot of wire, this project is actually a wireless charging system. [Jared] built it as a way to explore the concepts behind transferring power inductively. Alternating current on one of the white coils induces current on the other. This is then rectified, and regulated for use as a 5V charger. In this case … Read the rest
Transformers certainly have a tendency to increase the cost of any project, especially if you need a large transformer to get the job done. Microwave ovens are great sources of free transformers, though they are not always in the shape required for your next build.
[Matt] put together three great tutorial videos covering the basics of salvaging Microwave Oven Transformers … Read the rest
Here’s a couple of clocks that use Arduino boards to control inexpensive clockworks. The concept is quite simple, and perhaps best outlined by [Matt Mets'] article on the subject. As it turns out, these clockworks are driven by a coil, forming a device that is quite similar to a stepper motor. If you solder a wire onto each end … Read the rest
Be sure to check out Part 1 of the KC Maker Faire photo series. In this post, we explore some of the big hitters of the show, including crowd favorites ArcAttack, as well as battling robots. Read on to see the wonders!… Read the rest
