    Control ANY Light With Philips Hue

    Hi,sorry - time is a bit rare these days...On first look I'm not 100% sure about that dimmer-module - could work...you need some Optocoupler which is on that board. The output is 3.3V but very weak and inverted... so probably you will also need some extra transistor to invert the pwm and get some more power.

    Control ANY Light With Philips Hue

    Hi CaiusTitus,I tried to run the daughterboard powered by motherboard without the LEDs ...without success. I didn't manage to run it that way.... lost connection to the controller .... voltages and signals went crazy in the moment I disconnected the LEDs... to run AC voltage lamps n-chnnel mosfet will not work! you could try some "solid state relais" --> there are other ways but this could be quick & dirty solution!Have a look at switching times (pwm signal is 1KHz) but should be no problem.The PWM signal directly on the board has not much power - if you connect an additional transistor or mosfet or solid state relais this will not work! Thats why you have to replace the onboard l transistor or modify the circuits on the daughterboard.

    Hi everyone,sorry for the long delay .. I'm very busy these days...BINGO - The NPN is BC107 and the mosfet FDH5500 - as tekkfreakk already mentioned! (good job) a Vishay IRFP064PBF is fine too.The 3.3V PWM is very weak! even joust connecting the BC107 parallel makes a ugly wave out of the nice square-signal!And its probably possible to find other solutions - but I have not the time to do more reverse-engineering - so my solution is quick and dirty ;-)I bought the bulbs ad Conrad.de (here in Germany) - important ist the latest revision! Her in Germany are big electronic markets - selling the old versions of the hue bulbs! But in some online-shops like conrad.de they tell you that it is the latest version they sell! The latest version is labeled silver on white background - see pictures!O...

(the PWM is about 1kHz) So always use a PSU with lot more power then needed to avoid this!
