Led stays on!

[don_gt69]

so I'm new to the forum so sorry if i don't have proper forum skill set. but I'm not new to wiring or soldering at all its actually part of my everyday job..So my problem I'm having is with my saber is when i press the switch to retract the blade the led only dims and doesn't shut off completely. everything else works and functions great! I followed the custom saber shops build tutorial and you tube to exact details i even watch part one and part 2 3 times before i started and i was building along with it. used all the same parts as well.. ( this is the videos i followed) https://www.youtube.com/watch?v=pOpUSCsXXhk (and this one) https://www.youtube.com/watch?v=sApB7J5JdZ4. and here is a quick video i just uploaded to you tube to show everyone what its doing.. hopefully i can get this resolved. thank you every one for you suport on this and cant wait till i get to use my saber!!! https://www.youtube.com/watch?v=cEjJG97WLHk


update: if i take the battery out for about an hour then put it back in it wont do that right away but after about 30 sec the lights will not shut off. im so lost on why its doing this. im going to get a new/different battery and see if that fixes my issue.

Looks like you have a short somewhere. We'd need some good shots of your wiring and solder joints. Something is allowing power to go around the board.

Yep, Check everything first. Especially if you're pack is custom made- sometimes there might be a unwanted connection there- learned that the hard way myself!

What are you using for the soundcard? Sorry if I missed it in the description or video. I had a similar issue when I was finishing up my sons Ezra inspired build using a soundboard out of an ezra toy. My issue was I mounted the transistors for the leds to a heatsink...not realizing that they bleed a little bit of current through the heatsinks. Once I removed them from the heatsink and put each in its own heat shrink sleeve the blade would fully shut off, and the FoC would work.

edit: Sorry I saw the NB in the video the 2nd time though.

thats what im thinking as well. i have a crap camera. ill try and get photos up soon . but is there a amp limit to the nb sound board. cuz on first power up everyhting seems to work fine then about 1 min into use the light will not go out. .. im going to keep looking it over and over again., and if i can get photos i will. most my solder joints are heat sink though. thank you for the reply hopefully i can figure this out.

what was your issue you were having? and i might just have to spend a day and try and re wire everything,.

yeah the nb v2. yeah something has to be leaking somewere. .... hmmmmmmmmmm....

[don_gt69]

Do you guys think it could be the battery? What's the max amperage the nbv2 is rated at?

[Cire Yeldarb]

NB has a 5V limit from the battery.

And I believe if the LEDs are trying to draw more that 2A through the NB there will be problems as well.

i know of the voltage limit. its running a single 18650 got the trussfires from there site on the way. i was wondering if it had an amp limit to the chip.
also im using the rebel star royal blue led with a 3-5watt 1.5 ohm resistor. and the veriable resistor they sujest for the switch lighting. im hoping that the issue is with the batteries if not im going to tear everyhting bown and start from the beggining. i just really hope its not a bad chip.

thank you for the reply.
