    Supercap D cells

    I think that it would make more sense on installations which you DO NOT want to maintain. One example is solar cells put out a pre-defines maximum voltage. Add a few more volts onto it, you wouldn't have to worry about damaging the capacitor. For certain there is no worry about over amping the...

    Driver for a Luxeon III 3 Watt LED?

    I belive that the Elektrolumens driver will do close what you want, at 750 ma for 2 cells or 1.5 A for 3 cells. Another thing you may want to consider is a mikropuck. They put out 350 ma, and they can be added to one another, so that 2 are 700 ma and 3 are 1050 ma. Elektrolumens also sells...

    Where are you guys getting Satellite Phone? I am talking about a Satellite Radio. A Satellite radio has $7-$10 a month subscription several hundred channels commercial free. It recieves, but doesn't broadcast. Africa shares a geocyncronus satalite with europe. The US version of this is the...

    High Current v. High Capacity Cells - Updated

    Re: Head to Head: High Current v. High Capacity Ce High Current nimh cells can usually charge and discharge at about 25C. C is Capacity. This means that a 10AH D cell can supply 250 amps of current for about 1-2 min before going dead. I belive that the honda insite uses 96 D cells in series for...

    peace core and solar battery chargers

    While looking around I found an old solar charger sitting in a drawer. It was doing no good there, so i gave that to her along with a 1 watt 3AA flashlight that elektrolumens used to sell. The elektrolumens light will go along with the other lights which people have given her, but when she...

    peace core and solar battery chargers

    I have a friend who is going into the peace core in Africa and the people she will be living with will probably not have electricity. She hopes to bring a radio and a light to read by, but will probably not be returning to the states for 2 years. I would just get her a head lamp, and one of...

    Capacitor question

    abit had a bad batch of capacitors. Their cap supplier used a cheaper vendor who had stolen the method of how to make the caps from their largest competitor, however there was a step missing. Due to that the caps fail after 1-3 years. I would reccommend calling abit. I belive that they had a...

    Luxeon area lighting

    look at this one: http://www.advancetransformer.com/xitanium/advance/products-led120a0350c33f.html It does 1-8 leds in series at 350mw The only limitation I see is that you would need to run this off of 120 volts.

    Did You see this rechargeable ?

    If you like those, check this company out. They make fairly small sized capacitors at up to 2.6KF. http://www.maxwell.com/ultracapacitors/products/large_cell.html I think that this could be fun either coupled with a battery, or you could have a base with a battery and charging circuitry...
