The IR Miniature
Posted byHere's some information on the IR Miniature that I made to move the virtual mini's on the game map. It is a much better method of moving the mini's than the IR pen.
Parts List:
High-Output Infrared LED
SPST 0.5-Amp Momentary Switch
15 Ohm 1/2W Resistor
CR2032 Battery Holder
CR2032 Battery
Wooden Disk
Miniature Wooden Flower pot
5-Minute Epoxy
These are just the parts that I used, but you can always come up with your own design. One thing to note is that at the time I made these, I used a smaller battery and holder that has since been discontinued by Radio Shack (CR1220). If you are able to locate a CR1220 battery holder, then I would recommend using that since it's much smaller. If not, the CR2032 should work just fine since it's the same voltage, it's just larger and may not fit in the flower pot case that I used. Once I had everything wired together, I filled the pot with epoxy and then used a piece of cardboard to push the battery/battery holder into the epoxy. As the epoxy cures it gets VERY hot and so you'll want to use something other than your finger to hold the battery into the epoxy until it hardens.
Here's a picture of the inside of a finished IR Miniature.
