Does anyone have any tips on how to make a drawer that would open at the push of a button?


I was thinking about making a drawer that I could just push a button and it would open.  I have access to multiple disc drives, dvd players, printers, and scanners that I can take motors from.  I am relatively new to this type of thing, so I would appreciate any help.

You don.t need a motor, just a big spring on the backside of the drawer. Cash register drawers are spring operated. You just need to make sure the glides are close to friction free, such as rollers in a rail. When you push the drawer closed it loads the spring for the next time.

My dad had an old roll top desk with a hidden drawer with a small leaf type spring attached to the back and a well disguised release lever. Lift the release lever and the drawer be pushed out about halfway by the spring decompressing.
Push the drawer back in to compress the spring and lower the lever to secure it in place. It was a rather clever design.
That's probably a better approach -- spring or weight to open, so all you need to do electrically is release a latch.

Probably safer too -- things that close under motor power risk pinching someone.

The idea is sound, but the motors contained in the devices you outline are probably insufficient to the task, since none were ever meant to move the kind of force loads a drawer (or more importantly, its contents) represents.
