Hi Ian,

I have 2 questions:
1. is the position C4 with the 220uF and 10 Volt OK?

2. After which Flassch Gin did you have the idea with the milled out WS2812?
It takes a little bit of sensitivity to carry the WS2812 into the tube plate.:) :)

Hi Marvin

C4 is on the regulated side of the low voltage: 10V is fine, the regulated voltage is 5V.

The reason for putting them in the board is very simple. If you have a failure, the WS2812B can be replaced without destroying the tube.

The trick is to take a small square file and very slightly file out the square hole if necessary. The problem is that the square holes are routed out with a round bit, and it leaves the hole a little tight. Two or three strokes in each corner of the hole is enough.

I see the results you have are perfect, but perhaps you had to squeeze the WS2812B a bit. There should be some spares just in case.

Hi Ian,

this I will try again to rework the radii of the opening of the WS2812B.
Thanks for the information.

Best regards
Hartmut

Usually one or two light strokes is each corner is enough.

I did a little post-processing with the knife. Once the tube plate and the WS2812B.
Everything is fine and the first clock is already working.
