    Is there a IC for sale that contorols a RGB led ?

    Hi, i programmed a PIC12c508 to auto-cycle a RGB-combination of Luxeon 1W (red, green, royalblue). The actual programm allows to 'freeze' the changing-process and show the actual colour permanently. A 7Hz colourchanging strobe is also selectable. Schematics are available. Is this like what You...

    Potentiometer with switch

    Hi, if You use a standard 100k/lin-pot (with scwitch) to open and close the gate of a BUZ11 MOSFET you can use a cheap (and small) standard-pot and a cheap (and small) BUZ11 instead of an expensive (and big) power-pot. Just an idea.. Joachim

    Need Technical Assistance from the pros..

    Hi Zman, is this only the transformer (4V AC) or a powersupply (4V DC)? What colour is Your 1 watter (different Vf for different colours)? Vresistor = Vsupply - Vf R = Vresistor / I Presistor = Vresistor * I If it's AC You'll have to add a bridge-rectifier (and perhaps some 220 to 470µF to...

    CRYSTALITE by tonyb

    This is looking very good. My experiments were on bubbled glas with a colourchanging RGB-lightsource (Luxeon 1w red,green,royalblue) based on a PIC12c508 controller. It cycles through all the possible colours (>16mio) automatically with an optional 'freeze' and colourchanging strobe effect...

    LEDs can heal - Wired News

    Hi PhotonBoy, have a look at www.warnkeunited.de This is dealing with the fx of pulsed IR-light and pulsed electromagnetic fields. Dr. Warnke has been researching on this fx for years and i can tell you that it really works, even on horses where there is no need to tell them lies. unfortunately...
