Custom rotor balancing manchie

This rotor balancing machine is easy to make and not expensive. It is very accurate and you can cusomize to any rotor you need. It cost only 12 usd in parts if you already have the osciloscope and the spin motor.
I`m using two accelerometer and a reflection sensor. They are very cheap can be found on ebay.
Based on the amplitude and the timing between the refference point I can determine how many degree I need to add extra weight to balance it.
