We move into the wild lands beyond the manual by figuring out servo motor control... which lies about 0 and 180 degrees... I’ll have to dig into this mysterious servo.h library.

Both these were fairly trivial. The hard one was DC motor control with a relay. On to speed and position control in next session.

Status: I’ve learned to use the following things from the kit. 31 of 54 components. Gonna have to design my own learning experiments for all the others.

Spent an hour looking up what seem to be really finicky beaglebone blue JST-SH and ZH connectors. Why couldn’t they use more standard ones?

Trying to use this single-board robotics-specific computer to simplify my life, but realizing there are downsides now. None of these headers are the usual sizes. Anyone used this BBBlue board for a project?

Setting up for soldering phase of learning curve. Made smol hack with ventilation tube and shoebox so fume extractor pumps solder fumes out instead of recirculating. Air quality got pretty bad the first couple of times so figured this was needed.

Though my tube is a bit tougher (plastic-coated aluminum), so that’s good. I was going to 3D print an adapter plate to bolt on but the 4 screws aren’t long enough. Future yak shave. PM2.5 *really* blows up around soldering and I’m a bit sensitive so all mitigation helps.

There is a desktop fume extractor .. sometimes I use additional flux to fix cold solder desktop fume extractor plus I use a mask that i use for woodworking .. but yeah diy fan extractor will work .. just need to pull the fume and vent it out ..
