If you need a display for your next project you could probably use one from a defective Apple iPod however after looking at the iPod LCD Hack details I think purchasing a display that has a simple interface may be the ticket in this case. "Looking for a small, cheap LCD for a possibly large-scale project, I decided that the 2.5" QVGA TFT in the Ipod Video may be
A clever way to use a bicycle computer as a poor-man’s tachometer. While I’m not sure about installing it in my car, I’m sure it’ll come in handy down the road for another project. "Sometimes you just have to know how fast a wheel or shaft or motor is turning. The measuring device for rotational speed is a tachometer. But they are expensive and not easy to find. Its
Futz’s Microcontrollers & Robotics has a few balancing robots featured, the second version was built on the non functioning first attempt. It is still a work in progress but the build log is good and it will be interesting to see the progress of this project all the way to completion. Still seems that accelerometers are quite pricey, has anyone found a good deal on these anywhere? See a
Are you a WOW fan and want to get more immersed into the game? Stop running around using a joystick hop on a RunCraft and Race Across Azeroth! "We bought extremely cheap manual treadmills off of Amazon and decided to sense their speed with a mouse rather than trying to hook into the treadmill’s output with some sort of analog interface. I wrote a quick script in GlovePIE to
Wichit Sirichote has built a solar recorder that stores data to a compact flash memory card, there are full details including code and schematics available so that you can make your own. Even if you don’t need a solar recorder you can see how to store data to compact flash from a PIC microcontroller. "The EMF from pyranometer is 14uV/Wm-2. For 1000W/m-2, the output EMF will be .0014V. The
Miltron has made a cool Airsoft gun that can be manually or computer controlled. It is a good example of what can be done when you take some off the shelf items and mash them up with some electrical smarts. "The turret can be toggled between Manual Mode, where a Human interfaces with it using an Xbox 360 Controller, or Automatic Detect and Fire Mode, where the turret springs
The Wii sensor bar is nothing more than a few IR LEDs, this mod lets you convert an ordinary TV Remote Control into a Wii Sensor Bar. Simply open the old remote and drill a few holes for the IR LEDs. If the remote comes with two LEDs you are in luck, if not you may have to buy a few new IR LEDs. Disconnect the existing battery connection
