Test of differential bar for my yak rover build. Two 90-degree ball joints, two turnbuckle linkages, 3d printed bar and side brackets, nice red box from iPhone case for chassis. We make progress.
Making this my rover thread. First test of selected motor. A tiny compact N20 reduction motor geared down 298:1 with integrated quadrature sensor. Rover motor test. It’s noisier than I expected.
Bought a pair of these tiny turnbuckle rods with spherical joints for the 3-link differential mechanism on my rover design. They’re used in RC monster trucks for something. Found via a video of a rover build by a random hobbyist. Internet+capitalism = answer for everything.
Next challenge: assembling a wire harness for these tiny components and thin 24 awg wires is gonna be a bitch. Anyone have tips? Will need to crimp in tiny connectors that connect to a cable attached to board at other end (the pin count is off by 1 here but ignore that)
ngl this project is like 100x beyond my starting practical engineering skill level. It’s truly full-stack engineering from mechanical design to Python embedded control code. But I’ve already at least 3xed, so only another 33x to go. Goal is autonomous drive test by year-end.
While I didn't have to build a mechanical component . recent automation of garden irrigation comes little close..
ML model predicting when to water, iot devices gathering data, custom PCB n case n generic solenoid valve to control the drip lines plus usual frontend backend stuff
I haven't shared any..
I love frugal engineering readily available components n opensource tools for experiments .. all of this done in a rickety old thrown away desktop from work .. for PCB boards I utilized jlcpcb they r pretty cheap n fast
