Yep you read it right YELLOW DUCKS. For fun and to keep my niece and nephew busy I got them too making Solar Powered Yellow Rubber Ducks. All you need is few tools a soldering iron solder a large yellow duck, I got theses from Smythe the Toy shop about £4.00 with some baby ducks, they escaped. Some cheap and nasty Solar Lights I got 4 for £1 and a Pound Saver Shop. A drinking straw and a plastic spray tube of a WD40 can. A lump or metal about 200grm. Hot glue gun and sticks. In version 1 I used a old cassette players 3V motor and a cheap AA 1.2V Nickel Hydride battery. In version 2 I used again a old cassette playes 3V motor and a 10F 2.5V super cap from a old PC. I am about to do version 3 which will be the best so far and will paste up how you can do it for your kids etc. The above toy is version 2 see the Red PCB used as a prop. This is version 1 note the plastic Blue prop from a toy a broken windmill. This one only powered up in the dark as I use the original solar light PCB so in the morning it was in a new position on the London Docks. Version 2 only worked when it was sunny and bright but it could splash a lot so it looked funny. So now go build you own, my version 2 will be up soon as I get a new prop. HAVE FUN yes I am quackers honest Ballast glued to the ducks bum hot with melt glue.

They gave the kids hours of building time with no TV or PC games and then kept them out of trouble chasing the things around a pond trying to get them back, brain and body work out. And funny to watch I enjoyed it , but I was the mug that had to go into the pond bar foot walking stick in hand to get them out of the weeds, but worth every wet and soaking step.

What's the forward voltage of the BAT54 schottky? About 0.4V?
The reference voltage is about 0.2V.

Hey Colin, could you design me a SECA one, where the duck comes out of the pond cooked à l'Orange?

Well I set them free so if you find them they are marked with the Number 10 times the square root of 2 to one deci place, the big one is marked Danger Solar Duck Electric Shocks a Option. It is followed by lots of dead fish odd that oh well.
