Let's Make Robots!

Solarised Baby Mobile (aka Rainbow-Fish)

What better way to celebrate the birth of a new family member.

I jumped at the chance to make a solarised baby mobile to pacify our new arrival.

So here is "Something Fishy" for you.......

Solar Rainbow-Fish ..... (non stream version) (thats a joke by the way)

No these are not super bright Leds - this is simply crystal refracting rainbow light from the sun.






The idea was to make a simple fish that would rotate when it had stored up enough sunlight.

The resulting spinning effect throws amazing colours and rainbow patterns onto the walls,

thus providing some visual stimulus for the baby-

The cool thing too is it makes a very gentle purring sound when it "Swims".

Basic system :-

1x recycled solar torch.

1x recycled geared diskdrive motor.

1x Solar Miller Engine (with 1x3300µF "OB1 competion win capacitor" :-)

Solar Cell is inset into a hollowed out polystyrene ball (not an easy job to do)

Gold-Leaf details added...............fishy theme

Finishing touches ..........

Fish-Eye lens...........
