Forums member @VitalSparks has been talking with me about an idea he has for his upcoming scanner design. He is going to try using the concept of “constant power” to drive his motors. I did not know what that is and he was kind and patient enough to walk me through it over a series of texts and phone calls.
I’ve made a video that outlines the idea and how it might apply to Kinograph: - YouTube
Know anyone who could help us prototype this circuit? I’m out of my depth.
Here are some other links/resources that might be useful for further digging:
Possible chip for accomplishing this
YouTube video on varying load with practical application
