I cut my teeth on 0402's I was trying to make a brushless ESC for quadcopters. I got to the software portion and my project died, I hate sitting in front of a computer typing
As far as I can tell, a lot of low-cost optical rotary encoders are made using two slot detectors (or a dual slot detector) and an interrupter wheel. The interrupter wheel is either solid IR-blocking plastic with holes, or printed on a disk of something like mylar
@W5VO Good old days there were mylar encoders with a shape printed such that each "bit" output 8 levels of current. You could detect on/off, or 8 levels of on
@The Photon Yeah, I got the same thing but in the other direction, "oh you use an 0603? Well we don't have any of those left, how about a 1210?" Do these guys ever look at what they sell?
I'm currently building an induction heater, and mainly interested how it works and why it works, my induction heater is coupled to the work coil which is an LC circuit.
Now, if i get near resonance frequency, the current draw suddenly goes up, why does it go up? As the capacitive reactance and in...
