ThinBot Progress: To cap it all off -- Add a dome!

We observed last year that it was important to elevate one's power supply above the wet components of a barbot, lest leaks or condensation find their way into the wiring (one bot was offline for a while until its power supply could be replaced).

I'd already mounted my power supply and control relays on a shelf above all the other components of ThinBot, but wanted a little more protection from spilled drinks. Besides, a dome would just sort of finish the look.

After a bit of shopping (we considerd the outer bowl from a salad spinner, and another from a microwave popcorn popper, but they were both translucent rather than transparent) I found a polycarbonate serving bowl that I could repurpose as a dome:

Turn it over, it's a dome!
Turn it over, it's a dome! The bowl has an interesting shape -- a circular rim that morphs into 4 faces to become a square base; I've opted to orient the dome so that the sides of the square are parallel to those of the base of the entire 'bot (which orients as a diamond to the user)
Dome on top!

I wear a dome now. Domes are cool

I then reassembled everything so bovil could use a better camera for a final shot of the assembled ThinBot; I'll put that in a separate post.

    Ah, the best laid schemes... We dined betwixt earth and sky enfolded by clouds. No overlord's view informs the next sandbox city plan.

    Less rain this morning, so I pore over our maps plotting our sortie into the blustery day with grand engineering plans.

    Rain pelts my city and the towering spires melt into island mounds. Tomorrow I shall simply launch my fleet of motorboats! Tonka Marine Hauler
