Looking for ideas to move status indication 2 meters from battery charger.
Do not want to break seal.
10 leds- red, yellow, and green.

First thought is 10 photo transistors and 11 or 12 conductors. Only a couple meters and low current.

Can it be done with no amplification? ie. will I be able to find a PT with enough gain and sharp enough trigger point, to drive led directly?

If yes, I'm done. Only need to source parts.

If no. How about cmos schmitt trigger gates? CD40106

Also thinking about wired or wireless remote module if it's simple enough to code and decode data. Might be over my head!
