Tell us about yourself!
Dear Guido, how do you imagine the shape and placement of the coil? Something like in the picture?
The TCRT5000 consists a phototransistor and an IR LED. I've disassembled it and put the LED on to the transmitter board, and soldered the phototransistor to the arduino. During the operation they are opposite each other. The IR LED lights continuosly.
Of course, I take into consideration your suggestions. Absolutely agree with you, your idea can be better in case of higher current consumption because my little circuit has its boundaries in that field.
Yes, maybe I should make a new "Instructable" about this topic :)
There is a problem. The direction of movement of the magnets is parallel to the coil. Therefore the induced voltage would be zero. New coil design would be necessary.
Thank you, I am working on it and uploading more and more information.
Thank you. You are a real POV expert.
Thank you for your feedback, I really appreciate it. I will share much more information soon. Topics: how to gather parts, how to make coil, how to tune the coil pairs, how to solder SMD parts, how to programm arduino mini via Arduino UNO, how to set up the motor speed, how to balance the disc. Please tell me if I missed something.
Thank you for mentioning Tesla's name, actually I use Tesla pancake coil in this project. I have tried many types of coils. My experience is that size and the number of windings are not really important. Less turns - higher frequency, but same current and voltage. The point is the tuned L-C pair. So in my case the size was determined according to this project physical dimensions.
