Hi I have never used this site before, so I am sort of new too it, stuff I used to make 360 degree laser Spirograph, I found the link on YouTube, my constitution contains old DVD laser diode, scooter wheel and bearings, cardboard tube, two motors, cogs two sizes, wires, hollow metal tube, led any colour you like, old laptop hard drives because the platter are made out of glass, and some old Lego, and two speed controls what I have brought on eBay, I have got a video, but in the middle of editing
i used my children scooter wheels and bearings, and two metal hair grips to get the best tension and solder some wires to them and heat shrink, and used hot glue. lego i used to hold the laser diode in place
also used an old unbrella metal rods for the frame work and meccano, and driled a hole 8 mm hollow tube and solder it together, then with the cardboard tube i started to boar holes and incision to houses the motor on the side.
