Fresh hacks every day
Wardriving started out as a search for unprotected WiFi access points before hot spots were prevalent. And so this ZigBee protocol wardriving hardware which [Travis Goodspeed] put together really gives us a sense of nostalgia for that time. Don’t get us wrong, we love our pervasive WiFi access and don’t wish to go back to simpler times. But if the … Read the rest
Here’s a bulky tutorial that will round-out your understanding of ZigBee wireless communications (translated). The protocol is great for hobby electronics projects because it uses low-power short range wireless devices to build a mesh network. The guide covers both hardware and software, but also takes the time to explain what that hardware is doing in the background.

The Zigroller is a Zigbee remote-controlled balance bot. Although balance bots have been featured on [HAD] before, the Zigroller appears to be well-built and the project is well documented. Besides a section on hardware, the software for this build is documented here. The theory behind a balancing bot like this is given in this [MIT] paper if you’d like … Read the rest
[Russell] sent in a neat home automation project he’s been working on. Even though the project only has two devices so far, we can already see the potential of his project.
Instead of the X10 standard that has been a staple of home automation for more than 30 years, [Russell] went with ZigBee modules. Aside from being much faster and … Read the rest
I’m sure most of us remember playing with blocks when we were kids, well now this age old children’s toy has been crammed full of electrical goodness by a team of Electrical Engineers from the University of Texas. The Blox, which are about the size of a standard Rubiks Cube each contain 16 IR sensors, 4 touch panels, a 3-axis … Read the rest
Huge, fully functional NES game pad replica
Students at Dutch TU Delft university recently built a huge replica of the original NES controller (Google Translation), which is fully functional and can be used to play games on a large display screen they also installed. How big is it, you ask? It’s about 6 meters wide – over 30 … Read the rest
[Travis Goodspeed] recently tore down the Freescale MC13224 wireless radio chip in an effort to demonstrate how the device’s firmware could be read, even when locked down in “secure” mode. While you might not recognize the Freescale MC13224 radio by name alone, you are certainly familiar with some of its practical applications. Found in the QuahogCon and Ninja Party … Read the rest
