Titan (the car) saw it's first tornado! The base is a 99 SC2 weighing in at 3,000 pounds. On our first chase we easily got to 75mph and got around 30mpg. Still not complete of course.

There was a fist sized hole in the warehouse floor.

People kept tripping in the hole so I fixed it with what was laying around.

Couch foot broke off, fixed it with what I had lying around

More specifically the wood block connecting the foot to the couch split off. Duct tape was to hold it in place while I put in screws on each side, screws made the wood split, which is why the zip ties are there. Leaving the duct tape for aesthetic reasons.

Somehow it holds, tried it with me + my roommates on there (some 580 lbs total) and it didn’t budge

Battery spot welder from reclaimed power tool cells

Had one of those temu spot "welders", utterly useless stock il-po pouch cell cant deliver enough current to make an acceptable weld. Had several reclaimed high current rated 18650s from recycling power tool batteries, not internally shorted but with greatly diminished capacity so effectively useless.

Wanted to use a spot welder for building a pack with food cells, so decided to parallel up my junk cells to make a nice fire hasard / high current pack and use the control logic and drive section from the temu welder.

Results speak for themselves, not sure if crappy welder or just crap at welding.

Yes mom, asbestos underpants and full face shield were worn throughout.

Does an infrared sauna with app control actually make a difference or is it just a gimmick?

0 Upvotes

Looking at a few different units and some have infrared sauna with app control and some don't. The price gap between app connected and non connected models isn't huge but can save some money, and I'm wondering if it's a feature I'll actually use or something that sounds cool and gets ignored. Anyone using app control regularly?
