i found all the parts needed 2 make functioning air trecks! all u need is a load cell, or u can make ur own using 4 strain gauges. the rest is simple. if u dont kno, a load cell gives an output of electricity in accordance to stress, that stress can be anything, including WEIGHT! HA! :D:D that accounts for the weight aspect of at's. i will have this done in a few months so plz dont steal my idea. i'll sell u some if u want then tho'. me so kewl!
