    led driver for 20v to 33v

    I am thinking of adding this to a power wheelchair. Does anyone know of an led driver which can operate in this voltage range? The power wheelchair uses 2 sealed deep cycle lead acid batteries in series.

    Sure, headlights are useful; but w/ a laser??

    I bought one for my girlfriend for christmas. She is disabled, her arms don't work, and her legs don't completely work. She does everything with her toes and mouth, neither of which is good at holding a flash light. Her wheelchair has a 30 watt incandecent light, but that isn't too good for...

    7w Lux 'Minimighty' Tasklight Update-Part 2

    Re: 7w Lux \'Minimighty\' Tasklight Update-Part 2 If the brightness levels are linear, then there is less that you can do, however if you can set the brightness levels to get exponentially brighter, that would be ideal. If I remember right, our eyes see 10 times as much power as twice as...

    7w Lux 'Minimighty' Tasklight Update-Part 2

    Re: 7w Lux \'Minimighty\' Tasklight Update-Part 2 Or even a brace, like a way to mount it on the bike, where the holder has contact points which in turn cause the light to be charged. Look at the bottom of most cordless phones for an example. Annother option here is to find the most common dc...

    7w Lux 'Minimighty' Tasklight Update-Part 2

    Re: 7w Lux \'Minimighty\' Tasklight Update-Part 2 May I suggest cell phone batteries and cell phone chargers? ie nokia cell phone batteries and nokia cell phone chargers? There is two reasons for this. First you could probably get aftermarket parts for cheap when building them. Second, in...

    LumaPro- Cheap Deal!-GreatLight

    ...and the construction is all very decent. It is up to Mag standards mostly but not yet to elektrolumens D Blaster series standards. If you did 3 * 3 to D you could do 13.5V alkaline, or 9 volts 10.8 V rechargeable. I don't know if there is enough wasted space to mount a HID, but it should be...

    how fast is ya cpu?

    amd athalon thunderbird 1400 (not xp) 1 min 41 seconds. But I get 44 fps in unreal 2004 using a good video card, and benchmarks are the only thing I can find which makes my computer seem sluggish. It doesn't hurt that I am using a Gforce FX 5700 with 256 megs, and I have 768 megs of DDR ECC ram.

    Re: single \"D\" or \"C\" led? I had a need for something similar. See my post here. It should run an hour a night for over a year before getting dim, I have already accidentally left it on all night by accident with no noticeable difference...

    Why not stainless steel?

    To me this doesn't look machined, it looks punched. like the way they make cheap spoons. or think of an aluminum soda can. The head may have been cast. There are other ways to make tools besides machining them. But there are also problems with those methods. Many of them have to do with heat...

    NX-01

    I like the NX-05, but for different reasons that most people like it. I like it because it is so inefficient and leaks light all over the place. Because of this "feature" I have it taped on the front of my motor bike as a day time running light, which usually works except at high speed as a...

    $1.99 3led 4cell Pr bulb with pics!

    Re: $1.99 3led 4cell Pr bulb! OK, I just compared it to the arc AAA and it blows it away. They must be overdriving the LED, but who cares, at 1.39 a bulb, if the bulb halves in brightness at the same time the batteries do (5 years) then tape an extra one inside and replace it when you replace...

    Re: $1.99 3led 4cell Pr bulb! I got 2 of each, and while is dubious if the multi LED lights are any brighter than the 1 LED bulbs, (I can't test side by side. ) The one LED is very nice in a dimmer than Arc AAA way. I am using the bulb in a rayovac lantern battery. My initial problem was...

    $1.99 3led 4cell Pr bulb with pics!

    Re: $1.99 3led 4cell Pr bulb! It seems like a nice complement to the rayovac lanterns which cost less than their batteries on the assumption that eventually you will buy another. This way it should last nearly forever on it's original battery.

    Glow Paint from Glow Inc.

    I use this in several places. I have it painted on my cell phone, so that when I loose it after the batteries have gone dead, I need only wait till night, and turn the lights off to recover it. I have several coats painted on my light switches, so that I can find them at night. I my kitchen...
