Those planning to get married take note: real hackers print their own invitations on a press which they built. [Jenny] and [Charles] actually did this for printing the cover pages of their ceremony programs. They built their press using a chest of drawers from Ikea. If you look closely you’ll see the printing plate is [...]

This one might be an oldie, but it’s certainly a goodie. Way back in 2005, [David] and [Charles] needed a project for one of their engineering courses. With so many loose resistors scattered over the lab, they decided to build an automated resistor sorter (PDF warning) to separate these resistors and put resistors of the same value [...]

Here’s some very, very sad news from [Charles] over at The Maker’s Workbench: on July 16th, his house was hit by lightning causing his workshop to catch fire. His family is safe, but unfortunately thousands of dollars in gear has gone up in smoke. [Charles] lost a Reprap, a ton of dev boards, a huge [...]

If you want to improve the reliability of your electronics, just cover them in silicone or epoxy. Potting, as this technique is called, protects your project from impact and loose wires, but most of the time ends up as a gloppy mess. [Charles] figured out an awesome way to make pro-looking potted electronics using silicone and [...]

[Charles Gantt] and a few others were having trouble burning the Sanguino bootloader to an ATmega644 chip. With some help from the [Nils Vogil] via the RepRap IRC [Charles] got it worked out and wrote a guide for burning the bootloader using an Arduino as an ISP programmer. We’re not familiar with the specifics of [...]

[Charles] wanted to put some LEDs in his guitar. He also wanted individual notes to output certain colors, but he couldn’t find any projects with tone-based algorithms to convert sound into colors. After about a year of work, his ColorChord guitar was born. Unlike every other color organ build we’ve seen, the color of a note [...]

We believe that some of the best things in life are built from half-assed ideas and held together with duct tape. Take this fan-powered Razor scooter [Charles Guan] built, for example – it’s chock full of both. Having built a ducted fan-powered shopping cart in the past [Charles] is no stranger to ridiculous ideas. After a [...]

The Segfault is a balancing transport similar to a Segway, but it uses analog comparators instead of digital circuitry. On board you’ll find no less than twelve LMC6484 op amps. They take signals from the gyroscope and the accelerometer, balance and filter them, then drive the motor h-bridges accordingly. [Charles], the guy behind the Segfault, is [...]
