I picked up a couple of resin cast generators
at our club exhibition last November. Finally I got around to utilising one on
my layout. Previously I bought 4 micro motors intended for mobile phone
vibrators carefully removing the eccentric weight to expose the shaft; the motors
measure 4x8 mm ideal for this type of project.
Some tarting up of the basic casting
adding a radiator and exhaust mounting it on a redundant Hornby chassis, the
project was held up by some reed switches from eBay which were supposed to be
in London but were in fact in China! A 3volt
CR 2032 battery holder epoxy glued underneath.
A small magnet is hidden in the red toolbox to activate the motor.
Brilliant....
