Now kids can play foam swords and know when they actually score a hit instead of saying "I got you!" "Nuh uh!" "yeah huh!" "Nuh unh!"
This was built during the Instructables.com build night on Saturday May 18, 2013 using the Bare Paint conductive paint they supplied us with. It basically uses the conductive paint to close the circuit on the "target" that is worn to turn on an LED light to show when they are hit. I wanted it to have a super simple latch circuit that would keep the light on until a reset button was pressed but ran out of time trying to figure it out. I didn't want to have to put an arduino or teensy on the target just turn a light on and off. If you can come up with an idea to make it work please let me know and I'll make a version 2!
Here's a link to the photos I took during every single step of the process: https://plus.google.com/photos/116575142518321294189/albums/5880145339468857201?authkey=CMqqk8Snwfa-6QE
Here's the instructable I made to show how to make one yourself: http://www.instructables.com/id/Foam-Sword-Tag-Game/
