  1. No, the LEDs are not bright.

    While operating them at 2.9V, 2.8 V or 3 leds in row with the transistor?

     

    In my view, the input signal must be amplified anyway because the base current will be too low. I's suggest to solve it with an operational amplifier.

    If one led isn't bright enough at 2.8V, I would replace the transistor by a Mosfet.

     

    But there are certainly also other ways than my suggestion.

     

    *datasheet: Collector-Emitter Saturation Voltage = 1.2

    sry, i didn't read that earlier. (7.8V remaining->) 2 in row with a resistor :(

  2. ok a 2-channel light organ.

    I have found a circuit diagram of a 3-channel light organ with one LED per channel which can be modified well.

    Do you have the datasheet of the LEDs?

    A 9V battery may only last a few hours (depends on the power of the LEDs)

  3. When cloudflare is enabled, the visitor connects trough cloudflare to the server and the server doesn't see the visitor's ip. Cloudflare added the headerCF-Connecting-IP including the real ip.

    Strange that it works with other hosters, maybe they are able to detect when someone connects via Cloudflare and then they select the IP transmitted in CF-Connecting-IP for such proposes....
