Parts finally showed up.

Spent most of this one wiring. First time using a Raspberry Pi Zero so it took me way longer than it should have. Counting header pins with no labels
on the board is its own kind of pain. Had to keep going back to a pinout diagram to make sure I wasn’t about to put 5V somewhere it shouldn’t go ( i did two times loll).

Got the PCA9685 hooked up to the Pi, sorted out the power side with two separate regulators, one for the servos and one for the Pi so the servos
can’t brown it out mid step.

Also messed around with the software side. Getting the Pi connected to WiFi was more annoying than expected, ended up fighting that for a bit. Once it was on the network I could SSH in and start installing everything I need.

Did some more tolerance testing with the legs too. Printed a couple of test pieces to check the servo pockets and joint fits before committing to printing the whole thing. Came out pretty good, everything sits where it
should.

So this one was mostly wiring and Pi setup, with a bit of CAD and assembly mixed in. Not the most exciting to look at but it’s the stuff that has to work before anything else does.
