Some time ago I'd made various shipping containers, conexes, whatever you call 'em, for my
M1074 HEMTT/PLS. It was always my intent to make a regular semi-truck and trailer for them, and life got in the way, but eventually I made the Frobe and now I need a trailer for the conexes. (Conexi? What IS the plural? =))
This one was a pretty quick and simple build, as they go. Still had to redo some bits, either due to design error, or changing my mind as I went, but took, I donno, a week or two.
Originally it was gonna telescope for two container sizes, but that didn't work well in practice, so I punted for a single trailer with multiple sets of posts.
Short container
Long one
Same Arduino + DRV8833 in there, less hidden since it's an open frame design. Same code as the flatbed, so same adjustable landing gear, lighting, etc. (The lighting varies from one trailer to the next, so I use an indicator in the EEPROM to determine type. Way easier than having a different codebase for each trailer.)
And has a Neopixel LED on each of the six posts for side turns
Nothing exotic, but a handy way to move the containers about in addition to the flatracks on the HEMTT (PLS, whatever Frank is.)
