Lidl self powered jogging light teardown (with schematic)

I thought this was going to be a gimmick, but it's actually very good. Even the slightest movement will make the LEDs light.

The construction is strongly reminiscent of the first shake lights, but there are some unusual twists - notably the hollow core neodymium iron boron magnet. I don't know if that creates a stronger peripheral field.

The circuit boards are refreshingly simple, and yet the results are very good.
This is a three magnet system with the central floating magnet and the end magnets that hold it gently in a central position so it moves back and forth in the coil with very little disturbance.

This also keeps the channel independent of YouTube's advertising algorithms allowing it to be a bit more dangerous and naughty.
