This reminds me of my own experiments with making #LED decorations powered wirelessly
From my #TwitterArchive
Inductor, diode, 1000 uF electrolytic capacitor, TL431A for voltage regulation and a meteor shower LED #decoration which draws all its power from a Qi #wireless charger

A salvaged Li-poly battery from a discarded vape pen I found on the ground outside now powers my enhanced "Noel" decoration from #Poundland that uses a meteor shower light for the internal electronics

And with people making all manner of macro keypads and controllers nowadays to accelerate and skip over long winded GUI interactions we seem to have come full circle back to "The Mother of All Demos" (1968)

SDF is a function with 2D or 3D input, so any resources on plotting contour maps of multivariable functions would be relevant

I have 10pcs of those modules too. Problem is I now have over 60 unprotected batteries and I keep finding more. Might have to parallel them up or make my own BMS

I've salvaged so many unprotected Li-poly batteries from the street that I've run out of over-discharge protection PCBs. So I'm testing this rudimentary protection circuit which should shut off the TIP32a power transistor when the battery voltage drops below 3.2V = forward voltage of a white LED (2.6V) + base-emitter voltage drop (0.6V)

The disposable vape pen litter problem is as bad, if not worse, in the streets around my brother's house (near Manchester) as it is in High Wycombe
This is what I was able to find just walking around between Christmas and New Years Day. I wonder how many of these 8 lithium polymer batteries are salvageable

[Atomic 14] shows how to power #LED #Christmas lights with those free rechargeable Li-poly batteries you can find discarded on the street and along footpaths. Experiments with making them charge wirelesslessly did not turn out as planned.

That mathematicians are adding infinite diverging series of positive numbers and coming up with finite negative numbers as the sum, but if I had written that down as an answer in my exams in secondary school, it would have been marked as wrong
