  • It gives the amperage limit for resistive loads. Inductive and capacitive loads have a different power factor which changes the amperage limit, so maybe 8 amps for an inductive load like a motor. The instructions state “Current capacity should be derated for inductive and capacitive loads.” It’s why there’s a difference between watts and volt-amps.

  • It’ll still provide galvanic isolation. Sure you might lose a few thousand volts of protection compared to some optical isolators, but odds are you have a surge protector anyway which should keep it down to below your isolation limit. I would still throw in a 1n4148 snubber on the control circuit though.
    Plus an SSR would not be ideal. It would only conduct in one direction which is bad for ac motors, uses half the power for heaters, and probably double your peak current for an SMPS if it’ll work at all. You’d want a triac which would still involve a voltage drop where the mechanical relay would have milliohm resistance which can be ignored.

  • How soon for other colors? And how is the lens supposed to be retained?

  • A feature to add would be a diode test. My multimeter will tell the voltage drop which is good for LEDs. But I think it’s be nice to also test caps, inductors, and transistor pinouts too(the voltage drop from BE compared to BC is different by about a millivolt from my tests).

  • Next step, the video rubik’s cube, can only solve it by paying attention to a ball bouncing around.

  • It is an RCA connector, even comes with an RCA plug for making your own cable to use to hook up to the scope. And the BNC kit comes with an BNC to RCA adapter so all’s well with the combo.
    Time for me to get soldering.

No public wish lists :(
