Cool rainbow spinning wheel!

It did not take long until I found the problem, the flexible wire that is making an electrical contact on the outer aluminum tape ring is causing way to much friction and it is preventing the motor from spinning! So I had done some adjustments on the flexible wire and it is now causing less friction and the motor can now spin, but one set of LED’s are not glowing! I had kept making adjustments on the flexible wire that is making an electrical contact on the outer aluminum tape ring for more than 20 minutes, but I can never get it perfect. I wish I had some giant washers… So I simply gave up and remove the flexible wire that is causing trouble and connect the outer aluminum foil tape ring to the inner aluminum foil tape ring with a small piece of bare wire and aluminum foil tape. I have also modified the the 555 timer oscillator circuit, so now both sets of LED’s can be controlled from one negative output.
