Ok, i Will fix solders on data1 and batt+. until today I used termal wrap to block the component inside case and isolate the board from allumininu hilt.
I thought that termal wrap was a non-conductive material.
you say that it is not?
I donât know.
I do know that kapton tape is safe and doesnât stick too much, cause overheating, or damage Proffie boards. You can see through it too.
I noticed in your video the tape seemed a little thick. Up to you 
Itâs right next to where it says âV3.9â. Itâs made up of these three components:

https://fredrik.hubbe.net/lightsaber/v6/partmap.html#c7
https://fredrik.hubbe.net/lightsaber/v6/partmap.html#c8
Touching these components can cause problems, even with things that are only slightly conductive. Most plastics should be fine, but sometimes you get some oil or flux in there, which can cause a problem.
I reassembled the sword using the kaption type, I found it very convenient and the sword works properly.
However I used a kaption type bought on Amazon for about 7 euros per roll. I have seen others that cost up to 50/60 euros per roll.
What is the difference between these tapes?
Capton tape can be a bit expensive.
However, unless they are different in length or width, that is a very large difference.
The sword works fine but a strange thing happens to me. I connected a single blade built with a ws2812B led strip with 107 5050 smd leds. (originally 144 leds per meter but I only used 107).
I placed two led strips in parallel, so in total there are 214 leds.
When I connect the ammeter in series on the negative pole wire that carries the current to the blade, the ammeter never reads more than 1.2/1.3A.
I also tried to create a style with a completely white blade and without flicker but the absorption never exceeds 1.3A.
On the proffieboard manual there are different specifications and I expected a much higher absorption.
I also tried to power with the voltage generator which confirmed the same absorption.
Is this normal or is it a problem?
Or am I doing something wrong in the measurement?
1.3 A sounds low for 214 5050 leds. But current draw does vary, depending on where the LEDs came from. I would expect something in the 5-7 A range.
Is this a RGB or RGBW blade?
What was the voltage of the battery at the time?
Is the blade hooked up using 2 (or more) FETs on the proffieboard?
There was problem with my multimeter.
I removed battery end I used a generator to power the board and strip led, now the ammeter on the gereator read 2,65A for a single led strip of 107 leds.
Son 2 led streps absorb 5,2/5,3A.
I treyd to Power the circuit at 5v (only for test), so the single strip led of 107 leds absorb 3,5/3,6A acording to the strip led specifics.
Now I Will connect battery agan and assbley the sword agan.
