Hi.
I have picked up a old cash register thats broken, i pulled off the main bit to leave the draw. the draw opens with a solenoid and voltage is tested to open 9v+.
I would like to incorporate in some software im using to print a receipt that i could get it to call a software .exe then that sends a single signal to a port which in turn triggers the solenoid. I know i will have to put a relay in between as im guessing a std com port wont have enough umph to trigger it. I will test it soon and see the ampage i pulls, if i could get away without a relay and power supply that would be great.
Any ideas / schematics/ links appreciated.
Cheers
Stuart
