    RBG LED how to?

    madthug, if u want to use RGB or RBG leds remember that if u want white colour from them, u need to have equal intensities for each of the 3 colours. Keep in mind that different colour leds have different forward voltages which is minimum for red and maximum for blue. if to reduce the voltage u...

    Timer circuit using CD4060

    hi guys, i just opened up a uniross photosprint battery charger which has 2 timer settings of 6 & 9  hrs. i found that they used a CD4060 for the timing. The CD4060 is a 14 stage ripple counter. Can any one suggest any circuit for a timer using this IC. I'm planning to make my own battery...

    Some ideas for a 24VAC dimmer?

    i agree with audioguru that the heater element can work out with both AC or DC. use any simple dc dimmer or motor controller circuit as suggested by audioguru. u can use a PWM based curcuit for it.

    Ceiling fan remote control regulator

    Hi Nura, nice circuit, even i came up with the same idea but i discarded it because the circuit elements (the relays and wire wound resistors made it quite bulky). The circuit if i'm right switches resistors in the circuit thereby reducing the voltage and contolling the fan speed. i would surly...

    Need Schematic for Technics SA-370S Deck & Receiver

    Thanks for the datasheet. I already had it with me, but thx anyway. i seem to have solved the problem, it seems that the technics guys had put a .01mfd cap across each contact of the main power switch for contact suppression. one side of the switch was not functioning which caused the cap to...
