At least as done as I need it to be.
Used a piece of scrap 2×4, resawn to a little over 3/8″.
Planed cut smooth after each slice.
Then smoothed the rough side of each slab. My bench hook was a little too tall, so I had to shim them up with a bit of 1/4″ plywood so the plane would clear.
I held the LHSWBBT next to one of the slabs at what felt like a good angle, and ran a pencil line. Then stuck the two sides together with some double sided tape and cut on the band saw.
I needed rabbets and dados for the top and PCB. Started out cutting free-hand with a utility knife (they’re only about 1/8″ deep), but realized it would be a lot easier with the Dremel plus router base and a straight edge.
There is no pretty joinery here, or even any attempt at it. The side which supports the hand is one of the slabs laid flat and planed to the same angle as the sides. The dados hold the PCB in place and everything is held together with three screws on each side.
The bottom has been left open (easy to rewire/add things if I choose). Undo the four top screws and the cover lifts off. Nothing fancy, but this thing is fully functional.
How’s It Hooked Up?
The software is here. Just a simple little hack. The final version is almost the same as what’s posted. All that’s changed is some extraneous junk has been removed, and the thumb button now acts like the left-control key on the keyboard.
And here’s a fancy hand-drawn schematic.
