Intro: Tazer Tag
A while ago I made this thing called Tazer Tag... "a tele-tactile game of submission and fun"... It worked by allowing users to wirelessly shock each other with varying amounts of electricity based on their distance to one another. The last person playing won.
I never documented it's creation completely. Initially I meant to go back and fill in the gaps and post how-to instructions online so that people could make their own. However, after realizing just how dangerous it actually was, I decided against it.
Any which way, I did take some pictures of the first step of the process which involved hacking an avalanche beacon. They aren't the best pictures, but you might get the idea. In terms of the technical features of the project, hacking the avalanche beacon was probably the most interesting and most useful aspect since it provides a reliable and accurate form of short-range telemetry.
Don't bother asking me about the electric shock components. I won't tell you.
