Laser Pointers are great entertainment for cats, but those pesky LR44 batteries don't last long. After my cats revolted because I forgot to buy batteries, I decided there had to be a better way! A bit of time tinkering, and I came up with this fairly easy way to use AAA (triple A) batteries instead of the LR44s. This probably only works for pointers that use the LR44.
Parts and pieces. (Bits and bobs)
