    Hi

    I am an absolute beginner to electronics, what I need is construction
    details of a 12volt solenoid (how do I make it myself, and what
    strength pull can I expect, I was hoping to be able to lift up to an
    8oz weight)and a circuit that will switch it on and off between 1 and
    10 times per second, is this possible using a 555 timer, and variable
    resistors?


    Thanks in advance for any replies
     
  2. The force a solenoid produces is a big function of how long a distance
    that force acts over. Making one that provides a half pound of force
    with a lift distance of 1/16th inch is easy. Making one that pulls 8
    oz. through an inch is much harder (larger, and more power hungry. In
    either case, it is quite likely that you will have to add a transistor
    to the 555 to switch enough current to operate the solenoid. Is there
    some particular reason you need to make the solenoid, yourself,
    instead of recycling one from a relay or some other device?
