My first jet pack experience was some what underwhelming.

Transformer.....
Try a steel bolt with the coils next to one another rather than inside one another.... I'm curious if the power factor will be increased. Hmmmmm.Comment

Hot rotors, this is from a 2010 Subaru that had a brake caliper that was hanging up. While this rotor was hotter than the rest it's the heat distributuion on the rotor that caused me to stop and think. What's going on here ? You would think that the hottest part of the rotor would be the friction surface but the camera show the heat to be concentrated on the hub and the fins. Two thoughts come to mind. First, this is the way the rotors are supposed to work, drawing the heat away from the friction surface. Or, it's the nature of thermo cameras. The friction surface has a more reflective surface and the camera has a harder time measuring the true temperature. ???? More experimentation is in order I think.Comment

A 2010 Subaru is not a Chrysler product. It just sounds too new to have a problem with a stuck caliper. Did you crack the bleeder to see if it releases the drag on the rotor?
I love the Big Picture view of the temperature ranges of the thermal imager, but somehow still getting by with my $25 Port Cargo Thingy that 10 years ago introduced as new hi tech might have set one back several Hundred bucks on the truck in The Blue Dildo Line. In 5 years Thermal Imagers will be getting dumped at Port cargo for sixty nine ninety five.Attached FilesLast edited by Witsend; 05-06-2017, 08:28 AM.Comment

I've got one of them $25 thingy heat sensor measuring devices, well its not $25 over here LOL, it's a bit more £££ but same thing. I'm impressed with the thermal images from the new toy, my dealer keeps trying to sell me one, but not sure how I would make any money back from it.
I have a full computerised roller brake tester so no need for it there, don't do much if anything with heated seats, mirrors etc at the moment, nobody ever complains about that sort of stuff at our place.Comment

Initially when the pad is pressing against the rotor, that would be the hottest area, That flat exposed area may dissipate the surface heat pretty quickly. (watch a NASCAR rotor going into the corners at short tracks)
Definitely worth some more observations Bob.Comment

So I saw the Engineering Guys Video on the drinking bird (link below). The one remember from when I was a kid in the early seventies. The explanation on how it works is as follows. The bird head is covered in a felt type material. When dipped in the water this creates evaporation which cools the head which then causes a pressure differential in the gasses inside the bird which then causes the liquid to rise to the birds head which then tips again into the water which allows the liquid to return to the base and the process repeats. Closest thing to perpetual motion as you will get. So I thought I would check the theory with my thermal imager. It seems correct. you can see the temp difference even after the bird and the water have been sitting at room temperature all day. https://www.youtube.com/watch?v=UCKC-QVcVn0&t=331sComment

I've been playing with these addressable L.E.D. light strips. Pretty cool. Each LED has a red, green ,blue LED and it's own chip so each led is controlled individually. Just three wires for the strip, 5V, ground and a communication wire. I control it with an Arduino which can be programmed from a laptop. You can make all kinds of cascading patterns. It uses a NRZ communication which is incredibly fast as seen in the scope shots. I even hacked one of my Snap ON 5volt USB chargers for a power supply.Comment
