Stretch it!

Yeah, big ass fans are absolutely awesome. Their biggest over head fan is 30ft (10m) across

Yes, you are right, but I meant the safety shutoff mechanism. Normally it just cuts the power to all dangerous stuff or brings it to a safe state. Here it’s not “cutting the power to the magnet”, it’s physically releasing the helium and damaging the superconductor in the process.

Yeah, I can imagine someone thinking it’s entirely electrical shitting their pants too a sound of Smaug roaring.

If it’s not baked that actually sounds delicious.

Gasoline X Savages in my ass!

While I agree that this would certainly be interesting I don’t really know how this could work. First of all: Real current sensing can only really be done with a constant current driver. Not saying that this would be accurate but this should indeed work for an estimation. But now the first problem arises: Most CC drivers also include a FET for turbo and/or the higher range of the ramp. The moment this switches on you’re out of luck. Another option would be to add a sense resistor. This - again - would surely work to measure current. But you now have the problem that you introduce an (unnessisary) resistance in the driver, limiting the output of the flashlight (if it includes a FET). And lastly I just think that while it surely sounds like a cool feature it’s just not something most flashlight enthusiasts would use regularly. Altering the flashlight circuit for a feature some people may use once or twice out of curiosity with a given flashlight does not seem reasonable and ToyKeeper IIRC has many things on her to do list that she wants to implement. Since this is such a nieche feature that (for what I know) would need hardware modifications on many flashlights out there, I don’t think that this will get implemented.
