R U looking for a mfgr? Parts available from many sources. My favorites are DigiKey, Alliedelec, or Newark.

We sell small quantities of these flashing LEDs that you are looking for. On checking we have three different reds in stock, E157, E158 and E158 are the part numbers. Check us out at intl-lighttech.com

Google "joule thief" for some simple low voltage circuits. Go to www.makezine.com and search on "solar powered" to find a bunch of simple solar power hacks of various devices, and then "motion detector" for some of those.

That will give you a decent idea of what is available technically. It's not clear from your post exactly what sort of help you are looking for.

G24 Innovations can provide compact, flexible photovoltaic material for your application & many others. See www.g24i.com.

Interesting stuff but not exactly what I'm after. Need a complete unit to place inside a small toy.

If it's a drink coaster.. Then you have shown your hand.

They have been done too..

Otherwise, the mechanism is usually a tiny spring with a wire in it. a real hair triger!

how did I get a score for being off topic? By giving an answer with a prediction?

Did not mean to insult you but this is not a guessing game. The actual shape of this item would give it away. It could be an elephant or a space ship.

I am just looking for the part.

Kelsy,

Have you considered contacting a printed circuit board company? They can probably help you pick your components, design the board, and make a limited quantity for a reasonable cost. Then if you have success with marketing (and that is the really hard part) you can look at getting your cost lower. Lots of good ideas die when it gets to marketing. If it is as obvious or as easy as you seem to imply, you will want to do all of your research for distribution right away. There are lots of hungry manufacturers who will copy your idea (patent or not) just when you get a few months out. So, you may want to consider a strategy of hitting the market long enough to verify the demand and then get out by selling your idea to one of these hungry manufacturers. It beats watching it get taken away by someone who has no ethics or morals or respect for the little guys.

So you gave me off topic for guessing... ? and then you insinuate that I'm insulted by your action..

I was just guessing as to why?... I guessed right!

cool

I should get a lot of that..

good luck

Score me up for another off topic...
