There is a bunch of spammers on the forums atm, do you have a member deleting them?

Re: NDrive for LED bulbs

And if you are curious, this is actually one of the proper ways to use PWM to drive high current devices... http://www.rainwulf.com/storage/project/pwm.gif Though you can ignore the two transistors there at the beginning, as the arduino and the n-drive mosfet dont need them if you use short enough w...

Re: NDrive for LED bulbs

Any other way will involve extra circuitry. Remember LED's are current devices, they can run on any voltage, as long as you limit their current, as they display whats called negative resistance. They also have negative temperature coefficient which means that as they heat up, they can take more curr...

Re: EtherTen running hot

You can also power them directly with a 5 volt regulator on the 5 volt line. Plenty of those kind of PSU's are around.

Re: Sorry for the silence

I kinda know how you feel jon, just went on my honeymoon and had both maxillary sinuses infected. It was bacterial, and ended up with a 10mg injection in my arm. It was shitty as hell.

Get on the mend. Oh and i found drinking a LOT of water helped a lot with the draining of my sinuses.

Re: NDrive for LED bulbs

even the rgb modules that freetronics sell have a range of 255 per LED, and even on 1, its very bright. LEDs are just so efficient now and producing light! If its working for you thats good. The only way to increase your range is to use a different PWM system, or introduce a resistor into your circu...

Re: NDrive for LED bulbs

You mentioned circuitry behind the LEDs, thats the constant current driver circuit. If you have removed that, you do run the risk of blowing up your LED. The reason that even at a PWM of 1 makes the LEDs bright is that they are super high efficiency LEDs, so even the remote bit of current at a pwm s...

Re: NDrive for LED bulbs

Does your LED bulb array have a driver? Like a circuit behind it? If it has its own driver, fading it will be fairly difficult. The drive circuit will have a capacitor that will be charged whenever the mosfet is turned on, largely negating your PWM drive. You have to actually drive the LEDs directly...
