Of course, the easiest method would be a couple of springs.  One for each door.  Use the magnets, which are normally on, push against the spring to close.  Press magnet release button and the spring will open the door.  Easy and cheap! :)  Getting the spring right is the only tough bit.

This goes back to the mail I put on this list a few months back - I want to put doors on the side but with no handles - so the doors are as flush as possible - with a surround (so they cant be pushed inwards)

So I STILL need a system where I have a button, that actuates a release mechanism to push the door out - it can be held when closed with magnets - ANYONE got any ideas ? What I need is a good electrical personage (!)  

 

Talking about DIY motorised curtains and old wiper motors recently has suggested an idea on this one.  Why not hold the door closed with magnetic catches as you suggest, and use a salvaged central locking solenoid to push open the door from inside at the flick of a button/switch/macro.  These things require a 12v DC supply (quite a high current I believe, but only for a short time.  Something out of a Vauxhall Cavalier (A-F reg) or Astra (C-H reg) should do the trick.  Of course, you could go posh and use a Rover one :)

 

I have a (new) relay that has 'open' and 'closed' terminals which connect to the driver's door locking switch.  When the state is reversed, the relay momentarily switches the required polarity current through the solenoids.  Something like HomeVision could provide the switching signal for the relay I'm sure.  Sod's law reigns supreme in that until recently (3-4 months ago) I had a couple of nearly new solenoids laying about.  I think I gave them to a mechanic friend on the offchance that he might actually need one a some time in the future - I didn't need them as I stopped driving the Cavalier they fitted back in 1993!!!  If you're interested, I'll see if he can find one when I'm next round there.
