idea for a holo emitter?

I need a hologram emitter for a prop. It needs to be something fairly small and needs swithces and leds anyone have any ideas on things I could use or convert to work?

 

Do you mean holoprojector?

I saw some different ideas over at The Jedi Assembly, like making one out of a bubble gum tape dispenser.

Check out these threads for some ideas:

Honestly, if you want to convert something, you'll be hard pressed. I just made one out of some metal snapple lids and an old breadboard. Blinking LED's and a switch and vola! There's your holoprojector. I out an old solar panel on top to make it look good. Takes one button battery, but since I welded it shut...
