This one can actually be used for many other purposes other than sanding...
While it would have been nice to purchase a standard sander off the shelf, the issue of price as well as size proved prohibitive (as I needed it to sand just a few LEDs for my other project!)
I've added the pics of sanded and un-sanded LEDs for comparison...
I used LEDs with a wide viewing angle (120 degrees).
Step 1: What Do You Need?
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
