Calling all electronic geeks :)
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 http://www.cyberreefguru.com/fish/electronic/index.html and http://www.hobbytron.net/timers.html 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] Steve [ 07 February 2002: Message edited by: StirCrazy ]</p>

Hi,
What are the loading requirements on the 24VDC (load side) ? What is it driving ? Coil, motor, lights ? - Victor. [ 01 February 2002: Message edited by: reefburnaby ]</p>

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. - Victor.

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 Steve [ 01 February 2002: Message edited by: StirCrazy ]</p>

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

Hi,
Random between 1 min to 20 min and it's minimum adjustable (i.e. 10 secs to 5 min adjustable). - Victor. [ 01 February 2002: Message edited by: reefburnaby ]</p>

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... Steve
