Quadrature encoder is moved while power off
And an 8" floppy.disk was what, 360KB? The typical ARM controller might have more RAM than that.

Quadrature encoder is moved while power off
You know, in 50 years of working on and around machine movement, I can only think of one application where position was required thru a power cycle. A quadrature encoder based...

Quadrature encoder is moved while power off
There is something called an "Absolute Position" Encoder.   A quadrature encoder is specifically three outputs, an 'A' output, a 'B' output and a "Marker" output.   The...

Seeking suggestions for terminals for quick-swap battery
I use Anderson Power Pole connectors in my solar generator.  The Forklift industry also uses Anderson Power Pole connectors to connect the 1000Ah batteries to the forklifts...

MOSFET - AVR output isolation from drain/source volts ???
Actually, no.  But I'm relatively new to Fritzing and was not able to simply set 5V to Vx, or something.   Fritzing has limited voltage supply selection 0V, 1.7V, 3.3V,...

MOSFET - AVR output isolation from drain/source volts ???
One possible solution.  Crude, but workable as a starting point.   If you want full isolation, stick an Opt-Coupler in the gate circuit, as shown.   EDIT TO ADD:...
