I wonder if you were to use two or three separate coils along the length and wire them in parallel to the Bridge Rectifier, would that help build charge more quickly? I haven't tried it, so I am just wondering your thoughts.
could I use the capacitor in a disposable camera?
Probably but you want more Farads for longer term discharge. Most disposable camera capacitors are a special aluminum electrolytic capacitor, usually rated around 300V to 450V, capacitance in the 120uF to 330uF range. I would choose a supercapacitor like:3.0v 20F http://www.mouser.com/ProductDetail/Taiyo-Yuden/PA...
3.0v 50F http://www.mouser.com/ProductDetail/Taiyo-Yuden/PA...
Or whatever voltage you needed.
Yes, but it would be unnecessary. The capacitor is usually 50uF or less, and is 300V. You will only be generating around 3-5V, so the camera capacitor is pointless. I recommend scrapping circuit boards from AC adapters, and taking out the capacitor. They are usually 2200uF, and rated up to 10V. This will give you extra capacitance to store more charge, and go ahead and hook a bunch of capacitors up in parallel to get more capacitance! I did this and got over 8000uF from old capacitors I got from scrapping electronics!
thanks. because i have cameras in larger supply, i will just use a camera capacitor
Try not to go to Radio Shack, as far as I know, 3$ for an LED is bloody nonsense. I order online or go to a local hardware store, like www.taydaelectronics.com (I get LED's for 5 cents or less). I have a local hardware store "Harbor Freight", and they sell tons of rare earth magnets of all shapes and sizes for dirt cheap. I use these in my projects, and can pick about 20 small ones for 2 dollars. I recommend looking on Amazon or going to a local hardware store.
