Hack a Day
[Ajeromin] was asked to build something cool for a museum exhibit. He took the challenge, and with his facial capture device, we feel he delivered. The writeup is very short, most of the story is in the annotated images. After deciding he was going to do facial capture and convert it to 3d, he had [...]

If the kids have lost interest in that RC car or truck you bought them over the holidays, [Randy Sarafan] from Instructables has a few ideas that might help make the toys fun again, while teaching your kids a bit about electronics in the process. In his writeup, he shows how to swap out the [...]

The team at LeafLabs was looking for something cool to do with their new ARM development board. [AJ] asked if anyone had ever played around with Python, so [Dave] cooked up an implementation of PyMite and put it on a Maple board. While the writeup is only about blinking a LED with a microcontroller, they’re [...]

[Bertho]‘s submission for the 74xx logic contest is really impressive. He designed a capacitive sensing touchpad using only 74xx and 40xx logic chips. We’re impressed with the build and his writeup is one of the best resources we’ve ever seen for capacitive sensing. There are two ways to go about designing a capacitive touchpad. The [...]

[Fernando] is working on creating a game at home, with live scoring displayed on a large LCD TV. He’s keeping mum as to what the game entails, but he was more than happy to spill the details on how he planned to use the television as a wireless scoreboard. The writeup is the first part [...]

[Beth] had the idea for transmitting digital audio over S/PDIF on a Propeller a few years ago, but only just got around to a writeup. For that, we thank her. The writeup has a marvelous walkthrough of the S/PDIF protocol and the problems associated with with generating the signal. S/PDIF is a relatively resource-intensive protocol – [...]

[Alan] was commissioned to make some wearable, radio-controlled LED strips for the Travelling Light Circus. It has taken some time, but he has recently finished some prototypes, and thought it was a good time to do a writeup on the project. The system is managed by a single controller unit, which communicates with any number [...]

[Osgeld] takes on the classic VCR head jog wheel in this instructable. He has done a fantastic job not only in his build quality, but in the quality of the writeup. As he points out, the idea of using the head as a jog wheel isn’t new. His construction and build quality however have yielded [...]

[Rob] has made an astounding contribution in the effort to keep our libations chilled. Not content with merely refrigerating his cold ones, or even putting them in a cooler full of ice, he has built a beer caddy out of solid ice. Though it may look simple initially, you can see from his writeup that [...]

[Dustyn Roberts] takes us through the process of designing gears for a specific application. Using Inkscape and Ponoko.com [Dustyn] takes us from equation to physical gear. While there is a plugin for Inkscape that allows you to basically drag and drop gears, this writeup will take you through the math to get exactly what you [...]

This final project at MIT turned out quite nice. It is a CNC mill that cost under $100 to make. The tolerances are pretty tight as you can see in the pictures of the PCBs he has milled. He shows that he can even mill mild steel. It is a pretty brief writeup, but you [...]

[Howard] built his own replacement speedometer for his truck after the original speedometer cable broke. He’s using surface mount components and produced a two-board design that is quite nice. When he tipped us off he mentioned that this is Arduino powered and uses a hall effect sensor. There’s not talk of this in his writeup but we [...]

In this writeup, you can see how to build a cheap compound eye system for your robot. Using 4 IR LEDs and 4 phototransistors, [oddbot] gave “Mr General” the ability to follow movement in objects fairly well, assuming that they are within 200 mm. Being IR, it has the typical drawbacks such as sensitivity to [...]

We always enjoy a good performance monitor here. Especially when it includes some nice meters to watch jump and bounce as we thrash the system. This particular one is based on a PIC18f2550 pushing a regular old analog VU meter and an RGB LED. There’s a great writeup there, including schematics, PCBs, and massive amounts [...]
