MagicShine MJ-872 PWM filter mod

Backround: 

- Dimming the Magc shine cause a strobing effect especially while skiing in snow.
- Filming with a Gopro or phone camera cause interference in the video/pictures.


Here are some pictures talken from a Google Pixel XL phone. 

 

100% (no dimming)

Dimming 1

Dimming 2

So during the exposure it seems the light is stopping compleetly 3-4 times.
 

 Opening up

That yellow there is the filter capacitor about 470uF if i recall.

Adding 3000uF in parallel with the original.

Result:

100% ( no change, there is no noise to begin with)

Dim 1

Dim2

Dim3

Some stripes can be seen on the dimming but it is not by far as annoying as the original.
I guess this will address the most of the flicker and interference i see when using in combination with Gopro.
Isolated the capacitors and managed to cram them into the case. But it was a tight squeeze.
