Pursuant to the flight test dud, I have been redesigning the innards of the probe to fit on a single PCB for reliability so that (a) I don't have to pack a bunch of barewired parts with foam to try to get them to stop rattling, which as we've seen makes them fail; and (b) I don't have a bunch of parts rattling around with a LiPo battery in the probe body.
The new probe looks like this:
The forward support and rear cap for the PCB are being 3D printed. This is how they look, below. Note how the rear cap supports the PCB yet includes a generous cutout for access to the board edge connector and switch, and to expose the on-board temperature sensor chip.
