I have called this circuit the 'Oscilifier' as it is an oscillating circuit that seems to magnify the output of light from a light emitting diode. It uses a bifilar wound air coil in a very simple transistor circuit resembling a joule thief.
Magnesium graphite homemade battery. The human race has come a long way with technology, and in some ways we rely far too much on that technology. This is evident during a power loss when habit kicks in and we still reach for a light
Disposable cameras contain very powerful circuitry that convert 1.5 volts to 300 volts in order to set off the flash. This log shows how to modify the circuit in order to use a double a battery to light up a 10 watt fluorescent bulb.
This is a variation on the Baghdad Battery using only tap water as an electrolyte. Can you run a light, or recharge a small electronic device using only water? Sure!. While copper and zinc have a very good potential voltage difference
A simple explanation of how a plate array in a HHO electrolysis device also acts as a capacitor. When the unit is switched off the plates hold a slowly dissipating charge, and the plates still produce small amounts of gas.
Creating light from earth, air, metal and an acidic solution is not such a major task. Oxidation and reduction can be used create a potential difference between two metals placed into an electrolytic solution. These free electrons can be used
This is an example of a battery with a difference. I wouldn't exactly call it cheap power, in fact you could probably run a jet engine for less with the price of cheese around here being so high ... and i live right in the middle of farming country!
I've put together a very small series of voltaic piles to produce about 5 volts in order to run a small LED light. Through experimenting i found that the voltage does not vary much no matter the volume of electrolyte ... so why not go small.
The aim of this is to show how a battery works. You can link a few of these lemon in series to run a small LED light, calculator or clock. The lemon battery works because of the process of oxidation and reduction on metals.
The generation of power is about to evolve here on earth.Alternative power has been in the forefront of our minds for some time now and finally technologies are being developed to generate more efficient
This log deals with creating a portable USB iPod charger that should provide around three hours of video time once the lithium battery has gone flat. Working in a photograph development lab i see hundreds of AA batteries going to waste
