A few months ago, we covered Radio Shack's efforts to suck less, and the Radio Shack DIY team has now come back with the top ten suggestions submitted. Of course Arduinos make the list at number 1, which we somewhat expected for beginner projects. Here's the entire list in order: Arduino More kits and project suggestions More introduction/instructional books Larger LED … [Read more...]

Adding video out to the Open Pandora
July 22, 2011 By 29 Comments
There's very few users out there who actually have their hands on an Open Pandora Console. But the ones who do might find this hack useful for getting TV out up and running. It's actually not hard at all, but if you don't want to alter the hardware on the device you'll first have to find a cable plug that will fit the EXT jack. This proved more difficult than it needed to be, since TI carries the … [Read more...]
Using Binary Code Modulation to control LED brightness
July 22, 2011 By 14 Comments
Pulse Width Modulation is definitely the preferred method of dimming an LED with a microcontroller, but we were interested in hearing about a different method called Binary Code Modulation. BCM does the same thing as PWM, it turns the LED on and off very rapidly so that your eye cannot detect a flicker. The brightness level is a result of the average amount of time the LED is on versus when it is … [Read more...]
Resistor substitution box
July 22, 2011 By 15 Comments
[Vincent] on the EEVblog forums had an idea for an inexpensive resistor substitution decade box. The build uses cheap decimal thumbwheel switches he bought on eBay. Each switch is wired up with resistors for each digit, and each switch is wired up in series. The result is a small, easy to read resistor box with a range of 1 Ω to 10 MΩ. … [Read more...]
Beefy rover looks like tons of fun
July 22, 2011 By 11 Comments
[Eric] and the crew over at The Tech Junkies, just put the finishing touches on a pretty powerful robot that they call “Mantis”. The six wheel, chain-driven robot is pretty impressive at first glance. The robot is centered around a Netduino, which controls four 60 amp speed controllers. The speed controllers are tasked with driving four beefy CIM motors, which propel the robot along at a … [Read more...]
Modded Wall-E becomes a real robot
July 22, 2011 By 20 Comments
[DJ Sures] got his hands on a plastic Wall-E toy and decided to build a robot that includes a camera, voice recognition, and object tracking. The result is adorable so we're putting this video before the break: … [Read more...]
Hack a Day visits LVL1 hackerspace in Louisville
July 22, 2011 By 15 Comments
We recently had the pleasure of visiting the LVL1 hackerspace in Louisville, Kentucky. Any hackers in the Louisville area who haven't visited yet are doing themselves a big disservice. The space recently had its one year anniversary in July, but it's hard to tell. The space features many of the things you'd only expect in older spaces such as a laser cutter (added while we were visiting), … [Read more...]
