First of all, I apologize if this is the wrong group or if this question has been addressed in the FAQ.
I've been interested in circuitry for a while, and am now trying to design them. One thing in particular I want to do is create a setup where, after a given time, the circuit *breaks*. This is to trigger capacitors, which are connected to solenoids. I think you can guess (or is it guass?) where I'm trying to go with this.
The 555 timer seems to be popular, but from what I understand it rapidly flips between a low and high current. What would be a good way to do what I intend?
Thanks in advance, Bill
