umbrella light

Step 2 Disassemble LED flashlight

This particular LED flashlight style separated into the housing and clicker half, and the light assembly half. You're going to need everything except for the housing from both halves.

back half: battery pack on/off clicker (-) lead from clicker to negative terminal battery housing and handle

light assembly half: LED array (+ terminals) reflector housing

Cool idea with the flashlight, but yikes, why would you throw away what looks like a perfectly good 3 cell battery holder, when you could use it for another project if you needed to power something with 4.5 volts?

I guess not every prop builder is a pack rat like me.  ; )

It is said that many tribes the world over consume and use all parts of the animal which they hunt, the flesh, skin, even the bones! I envy anyone with enough space to keep the carcasses from made projects to use in future projects, but I'm just one man!
I try.

What is not shown in the pictures is the endless sea of crates filled with half-baked ideas, tools, and downright nonsense scratched on paper that should never see the light of day.

However, despite the lack of space, every time I start a new project my workbench is littered from the previous project. Pieces left over that I didn't have the heart to throw away. Somehow I always manage to keep more than I'm supposed to.

Hey, I was wondering if you could possible add a small linear electric generator in the handle of the umbrella so that as you walk the linear motion(up down motion that the handle experiences as you walk) would light the LED's without the need for batteries, or it recharges the batteries as you walk, whichever.

and maybe while the umbrella is not in use a small coil of nichrome wire is heated by the generator so that the handle of the umbrella is always warm when you take it out of your bag/handbag. or indeed a means of  trickle charging your Cell phone with the small amount of juice the generator would be producing while in your briefcase etc.
So what do you think? want to go into business? hey if you use this info in a commercial capacity I demand a E0.42 cent royalty on all umbrellas with this design...Please.
But in all seriousness, it's doable right?
