I've had this idea for years, but finally decided to make it. One thing that's always bugged me about the Next Generation tricorders is that they can't be displayed in the open position without opening them up and disconnecting the battery (since they automatically turn on via a reed switch when the door is open).
So I installed a second reed switch (well technically 3rd since there's one in the bottom to control the closing ratchet sound) in the back of the tricorder that would cut the power when it came into contact with a magnet. I then built a stand and imbedded a magnet in the front. So when the tricorder is in the stand, it automatically turns off. When it's off the stand, it turns back on, but the same opening and closing power feature remains intact.
Here's a video of how it works:
