Ok I need someone to tell me how to build this or what I can buy (for cheep ) that will do it.

what I want to do is use the magic box to alternate the 24Vac output between #1 and #2.
so when #1 is energized #2 is not. I have looked at some timer circuts using the LC555 timer and they might be able to do part of it as they have timing circuts that are adjustiable between 1 min and 60 min which would be perfect.

there are some good pages for ideas here

and

maby you guys who know whats going on will know if one of thease kits will work with a slight modification [img]images/smiles/icon_smile.gif[/img]

Hi,

What are the loading requirements on the 24VDC (load side) ? What is it driving ? Coil, motor, lights ?

it is driving a selanoid valve..
Electrical specification: 24 VAC, 50/60 Hz.; Inrush: .30 amps.;
Holding: .19 amp.

is that what you ment?

Hi,

Yupe. Thanks.

How flexible would you like your valves controlled ? An alternating pattern good enough or something more complex ?

I have a circuit in mind already...should cost about $10.

well at minamum alternat every 60 seconds.. time adjustible from 60 seconds to say 1 hour would be a bonus and randon between 1 and 20 min would bee the absolute bonus hehe [img]images/smiles/icon_biggrin.gif[/img] [img]images/smiles/icon_biggrin.gif[/img]

serioulsy though, alternating every 60 sec would be cool but if it isn't much harder the time being adjustable from 1 min to 1 hour would be cool

Hi,

Are you serious about the random part...it'll cost you an extra $5. (I am not joking).

- Victor.

hmmm why not, so you mean it will be fixed time(adjustiable) or randome mode?

Hi,

Random between 1 min to 20 min and it's minimum adjustable (i.e. 10 secs to 5 min adjustable).

ya that would be cool, but would the be a way to make sure it can't be cycled faster than 1 min?
I would hate for it to be on randome and start switching 15 seconds later...
