This is based on my design and requirements as in a previous post. Here it is:
|My (admittedly poor) design|
So here you can see one set of yellow LED's in a ring arrangement, the other left free for now. Then they are connected to a gold press button which I plan to install in the circular greeblie in the back of the head. (Not movie accurate. I KNOW).
After that is the CR2032 battery, which is slim enough to mount into the head 'bump'. Also seen is a 9V connector which I can use if there's room for a square 9V battery. I'm assured that ether power source will be good, but the 9V will be brighter and longer as one would expect.
All I need now is a head to wear!
