Ponghatduino: Play pong using your hat

Step 2 Velcro arduino and FSRs to hat

Once satisfied that the circuit works, get some velcro sticky tape. This is the stuff that has the fluffy and "hard" velcro parts on separate sticky tabs. Very useful stuff. I put two tabs under the arduino to stick it to the top of the hat and, after threading through the 30 gauge wire through the hats air holes, I velcroed each FSR to the inside of the hat band.
