Hummm. Seems odd. I would have expected $00 to $FF as output. So I'll have to install this box, and actually hook it up to see what I get.
I've found some old vfets I used as charge pump detectors, and bought enough to make a dozen of them. But the ink on the epoxy to220 bodies has gone away so they are now unidentifiable. I am able to determine the gate leg, but can't tell src from drain. Those two legs read 2+ megs to each other, either polarity. Those I have, the tip-120's are a week away. I wondered if the 3d printer state was such that I could make pcb's on it but some online checking convinced me its not quite a daily driver tech yet. So back to learning pcb-rnd and exporting gcode. I was familiar with eagle, a decade ago, but it was sold and destroyed. For vfets in plastic to220 cases, whats the pin order with the gate on the left? Anybody know which is src and which is drain?
