Hi people,
I need to have some stuff turn on for 30 minutes then off for 30
minutes all day and night.
I plan on a simple cam and a micro switch, but I need a 1-RPH motor to
drive it. I have searched the surplus places I know and drawn a blank.
Anyone know where I might get a 1-Rev Per HOUR small asynchronous gear
motor?
Thanks in advance.
Dave

Grab an old AC electric clock and slap the cam on the minute hand shaft?

In the UK we can get the likes of this
http://www.maplin.co.uk/Module.aspx?ModuleNo=32996&doy=4m7&C=SO&U=strat15
some as cheap as £4, electronic programmable versions are available as
well for a bit more. I would have though these would be available in the
US as well to suit US mains plugs. Are they not suitable.

Please log in for more thread options Hi all,
Thanks to Jeff, Jerry, Michale and David.
All good suggestions and as Micheal from the UK indicated, I found a
timer with 48 on-offs per 24 hours.
Appreciate the help.
And Jeff, thanks but no thanks with the ebay. Been there done that and
did not like the experiences at all, it seems impossible to contact
anyone there in a timely fashion.

I am a powerseller on Ebay with 100% feedback and take my customers
seriously. Selling equipment mainly, I recently tried to purchase NEW
car speakers on the site and got the runaround from seller for two
weeks only to find out they were on back order. Makes me sad when I
hear people don't like the site because I try so hard to do a good job
while some sellers are terrible. Anyways good luck with timer, best
regards, Jim.
