Hi Guys (Posted this on alt.electronics but it seems like only spam
lives out there)

I need to use 70V to power a solenoid for about 1sec at a time. I
would like to controll it with a PIC microcontroller.

What would be the best to get the 5V of the pic to activate the 70V
circuit of the solenoid? Is there any super transistor or is the only
way to do it by using a relay? Can somebody give me some google
keywords to find the right component to use and the applicable
attributes that I need to look out for?

In addition to that, I don't know how to get 70V from anywhere.
Preferrably, I want to get it from the wall socket. The transformers I
can find is only betwen 3V and 24V. I'm in Europe. Where can I buy
something that I plug into the wall and get 70V out. Again a few
google keywords will be helpful.

Safety: The 24V doesn't seem to shock me at all. Will 70V give you a
shock?

Thanks!

So John Fields' responses were spam? Smells kind of turkey-ish to me.- Hide quoted text -

No not at all. I posted the spam comment before JF started assisting.
This forum looks more active so I though i'll try here as well.

Crosspost. :-)

What does that mean? You're withdrawing the only support I got with
this? PLEASE dont!

LOL, I haven't withdrawn support at all. :-)

All 'crosspost' means is not to make the same post first to one
group and then to another, but instead to include the names of both
newsgroups in the "Newsgroups:" line. (The line which determines
where your post is going, whatever it may be called)

That way whoever answers your post (whichever newsgroup they may be
in) will send copies to all the other newsgroups listed and won't
have to go to each individual group to post.

Posting to each group separately is called multi-posting, while
posting to them all at once is called crossposting, which is
generally preferred in most related groups.

I've crossposted this post to alt.electronics,
sci.electronics.basics, sci.electronics.design, and
sci.electronics.misc, so if anybody's interested they might also
join in.
