This design has been around for a few years, but it looks like a good introduction to ultrasonic sensors. The design is surprisingly simple with a low parts count. Of course, if you prefer PIC controllers, you might like this version.… Read the rest

Tinmith Augmented Reality Backpack
February 22, 2007 By 8 Comments
I haven’t seen an augmented reality setup in a while. The Tinmith backpack consists of a VR helmet, with helmet mounted GPS tracking, firewire video camera, orientation tracking, glove based user interface and a belt back that contains the mobile computer and batteries. These systems have very interesting applications. From navigation to correcting information in real time to work around … Read the rest
printer networked light control
February 21, 2007 By 9 Comments
[Andy] sent in his ‘Network Something‘ hack. For his proof of concept, he used a parallel port printer network adapter to create a set of network controllable LEDs. The virtual printer was implemented with a set of shift registers and a set of nand gates. (and a power regulator). Old print servers can be had pretty cheap – … Read the rest
DIY Wireless NES controllers for Wii/Gamecube
February 20, 2007 By 11 Comments
[Mark] sent in his wireless classic nintendo controller project. He built a wireless NES and SNES controller to use with his Wii via the Gamecube port. He used off the shelf TX/RX hardware and used some PIC controllers to glue everything together. iPod batteries keep em powered and keep the weight down. He provides all the schematics and a … Read the rest
DIY RF remote control
February 19, 2007 By 7 Comments
I was plotting one of my future projects and found this diy RF remote control. I was struck by how simple the circuits are thanks to the micro-controller and RF modules. This is an older write up, and I know you can get newer modules from Spark Fun electronics, but when I was younger, RF controls always seemed to be … Read the rest
Keybot – serial controllable keyboard interface
February 18, 2007 By 13 Comments
[john] sent in his uncles Keybot project. The device accepts input (a parallel port in this case) and generates standard keyboard output. It allows a computer to create its keyboard input for itself or another machine. Personally, I go for serial consoles, but it’s a good study of our old friend the keyboard. (If legos are more your thing, you … Read the rest
Micron laser beam analyser
February 17, 2007 By 4 Comments
[David] sent in his laser beam analyzer project. It’s a complete analysis system built from off the shelf hardware. Even if you’re not into lasers, the project combines several technologies that are useful for the hardware hacker. A laser beam is focused to shine onto a spinning reflector. Beam signal is attenuated by adjusting the distance with a stepper actuated … Read the rest
