How can I make a compartment that has a drawer that opens with a switch? I just need the basic idea of how this would be done. Thanks

Well, magnetism attracts things that are made of iron or steel. Electromagnets can be turned on or off with a switch. If you place a piece of steel in a way that stops the drawer from being opened, you can switch on an electromagnet which pulls the steel out of the slot so the drawer can be opened.
The electrical part is the easy part. It's the "hidden" part that is difficult.

That sounds good too, how would I make the retractable cable system and spring system? What type of parts would I need?
The drawer would open as slowly as the motor unspooled the line.
A small geared motor would be enough. Find a happy speed.
I agree, If I were doing this, I would do the CDRom tray idea.
I mean the idea...not the exact parts.
I was thinking along the lines of cutting an automotive V-belt and laying it down as the rack gear, affixing it to the bottom or side of the drawer, then using a geared motor, find a drive gear whos teeth fit the teeth on the v-belt. Wallah! 1 super sized cdrom tray![]()
Thats an awesome idea, nice and simple with minimal parts. So far this seems like it would work best. Now what do i use to time the motor so it only operate long enough for the drawer to open?
