How To: Build a linear slide bearing for a CNC router

A CNC router machine is probably the most useful tool a hobbyist can own, but the price for a CNC machine on the market is way more than the average hobbyist is willing to spend. You can build your own CNC with very basic tools, little knowledge of machinery, mechanics, or electronics, but be warned, these machines are inherently dangerous, so wear the proper protection and use common sense. At the very least, read the instructions and precautions on every tool you use.

News: Touchpad Made with Paper and Pencil Scribbles

Who says nothing productive ever came out of doodling? Certainly not the hacker responsible for this fun (and at least somewhat functional) paper-and-pencil touchpad, which takes advantage of the natural conductivity of graphite: There isn’t much to explain here. It just uses pencil graphite on paper as a kind of two dimensional potentiometer. Four voltage dividers between 5v, 2M ohm resistors, the paper, and my grounded finger feeds signals from each corner into an Arduino. The Arduino does ...

How To: Wire a light with a 3 way switch

In this video, Mark Donovan teaches us how to wire a light with a 3 way switch. Before starting, make sure the power is turned off from the main circuit panel first, and you test to make sure it's off. You will have two switches for the same light fixture. For a 15 amp circuit, you can use 14-2 and 14-3 wire. These wires will have a black, white, and red wire. The 14-2 wire just has a lack and white wire with a copper ground. The power coming into the base should have all the wires that conne...

News: 3D LEGO LikeLight Shows You Facebook Likes in Real Time

How To: Hack iPhone jack to support headphones

As any informed PopSci reader will know, the iPhone is definitely a game-changing piece of hardware, but it's not without its problems. Chief among those nagging little imperfections, for me, was the recessed headphone hack that rejected any headphones but Apple's trademark gleaming white buds. Apple's 'phones aren't that bad, but my Shure in-ear pair is better for blocking out noise on the subway (and my Grado SR60s are better for listening at home). Thankfully, an easy solution to this prob...
