use more care with that knife. slow down Dave!  :palm: also your camera autofocus is BS , get a better camera, or mod it.
why all the autofocus out of focus.  :-// two setting are needed you at 2 meters and 30cm from the camera.

your an electronics engineer,  Let's work the problem. will two intersecting red 45 degree laser beams give you precise focus at 30cm?

Great points about the PCB layout, maybe it's even worth making an entire video about it, because I see so many people doing it wrong.

The binding posts in Array DC Loads (at least 372X series) are the best I've seen so far. Just saying.

For those annoyed that Dave (from Dickheads Anonymous) only showed the finished Smart Supply on screen for 1 second, and forgot to post the link in the description.

The Pictures section has all the photos of the finished device.

I couldn't find a source for those exact binding post adapters but here is something similar it. Never bought one so can't vouch for it.

Got one of the above adapters.  Fits my Maynuo load ok.  Cannot have the banana jacks below the input terminals as the board sticks below the unit.  Turned the other way there is just enough clearance for the adjustment knob.  Had to space it off the load with some washers because it wouldn't sit flush.  Banana jack studs on the back side are a bit long and hit the face of the unit without spacing it off.  The PCB is pretty thick so it doesn't flex much when connecting leads.

Not as nice as the unit Dave had, but its still better than dicking around connecting leads up for small current stuff and its cheap enough.
