I made a high speed video when I solder my latest board
Made this for fun to see how it would look in high-speed when i am working (PCB CAD) on one of the PCB boards on my latest project.
Needed a simple inductance meter when my regular one was missing.
I had to make a prototype charger to test and check my theories about charging VRLA batteries.
So i made a light ring with adjustable light level /power.
