Basically, You'll need a small DC motor
(size really depends upon how big and powerful you want it to be!).
Also needed is a base to mount the motor
over it and an extending shaft
and some sort of a coupling mechanism
to couple the the motor's shaft and the extending shaft. A 5g pack of Sugru
should also come in handy.. Also needed would be a power supply
(I used a switch mode adaptor) And off course you'll need some sand papers
to diffuse the LEDs...
(Things Bold and Underlined are necessary! )
In case you happen to have a DIY Mechanix (meccino) set
as I did, you'll need the following:
RT-55 (The red base) - 01 pc.
BTB-5 (the L shaped brackets --- optional --- it might rattle a bit without them) - 02 pcs.
SH-3 (110mm shaft --- you can go with any other length for the shaft) - 01 pc.
R-8 (the red rims used for coupling) - 02 pcs.
Motor - 1 pc.MOTOR
A spanner and a screw driver for tightening the screws
