  • Um...Hello?
Crystal Chamber LED question.
« on: January 06, 2019, 08:49:43 PM »
I am currently working on a MPP 2.0 build. I will be installing it with a Nano Biscotte v4 and a Goth3D Sith Master chassis. I have never installed a crystal chamber before with working LEDs. I will be putting 2 5mm Red LEDs that I bought from KR Sabers. I have a few questions in regards to the LEDs in the crystal chamber...

Do I need to wire the individual LEDs with their own resistor?
Where do I need to connect the LEDs to the NBv4?
Does adding the smaller LEDs have any effect on the main blade LED or overall battery life?

I see nobody has responded so Iíll do my best.

All LEDís  should have their own resistor.

If your running a led for a crystal I ran mine in parallel to the main blade.

I believe the Nano has one accent pad you can use for an accent LED but Iíve never used it. I jumped straight to higher end boards after doing a basic Nano so Iíve never looked into it.

I believe as long as the LEDíS have their own resistor brightness shouldnít be effective. If you donít put a resistor on each  LED I believe it will. As in if your running a RRW and you run one resistor ( one 1.2 ohm 3 watt ) to both red LEDís it will diminish brightness,  but it you give each LED itís own resistor it shouldnít.

The more LEDís involved Iím sure battery life is drained because more juice is required.

This is the best I can give you.  Hope it helps.

If you want the crystal to mirror the blade you need to wire it to the blade LED pads.  Best practice is to use a separate resistor for each LED. 

Anything you connect to the battery will affect battery life, but the 5mm LEDs will be a drop in the bucket compared to the board and the main LEDs.

The manual shows various wiring configurations and details, I suggest reading giving the manual a careful read.
