DIY Hacks
Map Bot – Floor Mapping Robot
Have a look at Map Bot over at GlacialWanderer, this robot is in the early stages but when it’s done it will be able to map out a floor. The main sensor it uses is an ultrasound sensor, one that most of us have seen many times before. But it also uses an interesting bend sensor that I have never seen before. Here are some details of the bend sensor
Popcorn Popper made from a Tin Can
Here is a cool popcorn popper that could be handy next time you are out camping. It is quite small so it may not be of much use if you have a big family but it is sure to be fun for the kids to pop some of their own popcorn in a can that they just used to quench their thirst with. 🙂 "Learn how you
Sewing Machine turned into a Jigsaw

Card Reader Project
Looking to try your hand at reading some mag stripe cards? This Card Reader Project has some great information and some code to get you started. "The Magstripe (Track 2) Reader project can be used to view numerics stored a magnetic data card. Although there is no writeback ability, the device is very useful as a card debugger. The treatise will use an LCD character display to relay
IR LEDs used to defeat Security Cameras
I have seen lasers used to "dazzle" security cameras before but they normally use visible light and need pinpoint accuracy to be effective. I had never thought about using an array of IR LEDs (infrared light emitting diodes) to create a permanent result that would not be noticeable to anyone else around. Original Version, Translated version "IR.ASC is an infrared light – to the device before Divining infrared surveillance cameras.
Gun Robot – PIC Microcontroller and VB.NET based
This Gun Robot project can monitor the entrance to your fortress and ward away any enemy attacks! The servo action seems nice and smooth, next step would be to make it IP based so that you could have the unit at work and control it from home. 🙂 "The bot is totally controlled by an external joysitck or joypad. The app uses DirectX DirectInput to get the data from
