Title: Connecting a solenoid?
Post by roy_pardi on 05/17/06 at 22:18:59
So I need to control a 12v solenoid through the wiring board. Do I need to isolate or protect the board in some way or can I just connect it to a pin + 12v+

I'm running wiring off an external power supply but it probably makes sense to use some sort of simple circuit to isolate the board. That's about as far as I've gotten. any tips?

here there is a diagram for a coil or solenoid: http://wiring.org.co/reference/electronics/coil.html

the MOSFET switch will handle the large voltage used for the coil.
here is one that I have used before: http://wiring.org.co/reference/electronics/symbols.html#150

i'm making a solenoid,
but i might need something like 160 Volt.
I worked on something with a compacitor.
Would this work with compacitor?

I donīt understand your question very well. Could you explain a little more? :)

the question from roy was about a 12v solenoid

Im making this:
1,5 battery to a flash circuit from a throw away cam(http://images.google.nl/url?q=http://www.delftintegraal.tudelft.nl/info/images/130503011055020.jpg&usg=AFQjCNH3V6izXjkGbzXWe3d9JFLEA7JWqQ)
which has a capacitor to about 330 V
I need only 160 V

Is that possible with wiring, or to dangerous?
and how would the scematic look like:
this is the scematic from the thing i read it the first time


"laadcircuit uit de wegwerpcamera" means "loading circuit from the throwaway cam"



a Thyristor TIC 126D
and
LDR as the trigger,

i hope i explained it well enough for you

Thanks,

Titus
