Hello everyone, I have fairly limited experience with circuits beyond simple stuff, but I need to set up a counter that will record the number of pulses that goes through another independent circuit and then displays the amount. Due to my limited experience and lack of proper equipment (little more than a soldering iron and a volt/amp meter) I was planning to simply modify something to suit my needs, but its not working. The circuit im trying to record from is releasing charges from a capacitor to activate a solenoid up to 15 times per second. I went and bough a cheap pedometer to try and use as much of that as possible since it has most everything i need (counter and display), and was planning on using a small relay in parrallel to the solonoid to complete the circuit that causes the pedometer to "count". I wired everything up in stages, the pedometer is functioning fine and counts if i manually touch the wires and complete the circut, and the relay is getting tripped when its in parrallel to the solenoid. But when i try it all together I get nothing; no counts are recorded at all. Im guessing the pulse from the external circut is just too quick to trip and relaese the relay for the pedometer circut to pick up... But maybe its something else? Anyways, im wondering if anyone on here has any idea of what I can do. Be it salvaging something from what I have, or compleatly designing something new, im all ears.
