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

@W5VO I was not. (Funny though. I would've known what a detent is without my background in lockpicking.)

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
 
4:21 PM
@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

I'll look into it. Although, I guess I should first figure out why that encoder is needed with the stepper motor...

Each vacation the same thing. I ask something and the wife just gives me the stare. I am just unsure about how many multimeters to take with me
 
@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 reading a datasheet and it has a pin labeled G with a bar overtop of the G.
what does that mean?
my first thought was "not-ground", but that really doesn't make any sense, so.
 
7:05 PM
Negated/inverted
 
inverted G...hmm
 
7:23 PM
or active low :)
 
7:43 PM
@heather G probably stands for "gate"
On the other hand, in the diagram on page 3, they label those pins as "Data Enable".
 
@ThePhoton ok, that makes a little more sense. thank you!

Q: tank circuit drawing current at no load when in resonance (induction heater)

Eric B AhapaidI'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...

@Marla This may be in your area of expertise.
