I need to build fifteen coin-op timer mechanisms for my internet cafe. I have the mechanical part just about ready, but eletronics always stump me. Logic comes easy but the sizing of resistors and capcitors is really beyond me. I have specs and part numbers for parts below. I could also attempt a drawing . Help me if you can or put me in the right directions please.
supply voltage is usb 5v
2 - slotted infrared optical switches (transistor type, normally on) HY860N
1 - JFET transistor ( to reverse on state of the first slot switch) no idea what to buy
1 - clock 1.2v (to remove the first coin in line and trip second slot switch to turn off timer)
clock has a disk instead of hour hand with projections to push coins or trip slot switch.
1 - voltage regulator (to provide power to the clock) LM317T adjustable regulator
1 - 5v relay ( to turn on/off computers and playstations)
resistors for voltage regulator and transistors
capcitor to protect against the coil in relay
The circuit works as follows:
coin enters first slot switch, with the aid of the JFET turns on the clock and the relay
clock turns and pushes first coin in line off the track, second coin advances (if any)
clock continues to turn, when it trips second slot switch, the mechanism goes off
Thank You for your help.
