DIY Electronic Timer with LED Displays for under $100 ... This timer has the ability to display individual lane finishing order and times (four digits) and transmit these times to connected PC (with 0.0001 sec resolution, though I believe the tolerances in the placement of IR LED’s and phototansistros is probably the weak link at this point). I think a comparable kit from Microwizard would cost around $350. I believe you could also probably build ... Tutorial 2: Transistor Timer Circuit Starting Electronics This will switch the LED off and start the timer. After the timer has finished timing or "timed out", the LED will switch on again. Try using a different value capacitor in the circuit to see the time period change. Using a 100uF capacitor will result in a very short time period. Using a 1000uF capacitor will result in a longer time period.
