First off, I apologize if this is the wrong forum. Given that this is a personal project of mine I decided here would be appropriate. Second, I'm a mechanical engineer so these will probably be simplistic questions for you experts (my school wouldn't let me take electronic classes).
I have a basic design in my head for circuit that uses a battery source to power a solenoid valve and is activated/closed by a reed switch. Its a 12v solenoid, but I would like to avoid the added weight of 8 AA batteries. I was hoping to use 1 or 2 batteries at most to charge a 12V capacitor(s) that would dump into the solenoid when a reed switch is tripped.
I'm pretty sure that I can't just connect them together because in my mind the battery wouldn't be able to get the capacitor to, let alone above, 1.4/1.5V. So I'm looking for a way to step up the voltage with minimal complexity/space/weight--no ICs, microprocessors and stuff along those lines.
