First on the list, updating the speed controller on droid #2. I updated droid #1 with a Sabertooth 2x32 speed controller back in April 2018, and now it's droid #2's turn. In both cases, the speed controller being replaced is the Vantec RDFR23. With any luck, maybe I'll be able to make the wiring a bit neater while I'm at it...
Out with the old.
Before bringing in the new, I need to cut a mounting piece of flat PVC. Dimension Engineering recommedns leaving some room for air flow for ventillation, so I plan to mount the speed controller to the PVC, and use some nylon standoffs to mount to the electronics board.
First I need to cut the PVC to size. I want this to be wide enough that the mount points for the screws don't run into the center leg, which leads up into the body and on which the electronics board rests. So I want to cut the PVC to be wider than the center leg outline on the electronics board. That's the idea, at least...
With the PVC cut to size and drilling points marked, it was time to drill the mounting holes.
And with the holes drilled, I can use this piece as a template for drilling matching holes in the electroncs board.
Next, I can use the speed controller mounting holes to drill matching holes in the PVC.
With that done, I can do a test-fit on the electronics board. In go the standoffs.
And the test fit on the board.
Still lots to do, but it's a start.
