Please read! Capacitor bank charger. 2180uF 330v (max, I only charge to 310v to leave for some safety overhead). Diagram farm8.staticflickr.com I am rectifying the transformers AC output using 4x UF4007 diodes in a bridge rectifier configuration. I tried using a packaged bridge rectifier out of an old PSU but it did not work very well becuase of the high frequency's involved with this driver. The UF4007's are fast recovery and can take up-to 1kV before they breakdown. This 700MB video took me 12 hours to upload! Points of interest: Transformer testing 1:44 Some high current arcs 3:34 Capacitor bank charging 5:55 Timing the time it takes to charge the bank 7:12 Blowing a hole into a soda can 7:57 Review 8:27 I am sorry about the cracking audio whenever there is a loud point. This was caused by my attempt to make my voice sound louder, which it did but it also caused the peaks in the audio track to become too high. Combined with how youtube seems to boost audio too it ruins the audio. I guess all I can do now is learn from this mistake and not do it again!

Today we discharge 5.5kV 50uf into film capacitors, electrolytics, resistors, LEDs, surge protectors, 7805 regulator, power transistor, and a LED array from a dead flashlight. Nothing survives this kind of overload. The capacitors go off with quite a bang, they rip apart. The red LEDs disintegrate so quickly that there is nothing to show in slow motion. A small ferrite inductor had the coil blown clean off it with no harm to the core.

Afroman goes over some basic information about capacitors: Capacitance, voltage ratings and polarity. Once you know what you are doing, you can replace faulty caps on your circuit board and bring your electronics back to life! Don't forget to vote! Panasonic FM series capacitors are usually a good choice.

*** PLEASE READ: This is another way to measure the value of a capacitor. I have a beter method in another video, but this is one often mentioned due to that a signal generator (ie sine wave frequency) is not needed. For safety, discharge any capacitor before working with it. Use some resistance (lower than the resistance of air) value across its terminals. Some capacitors are "polarized" and can only be charged with the positive voltage connected to the (+) terminal, and the negative voltage connected to the (-) terminal, otherwise it will probably explode. This method here will work good for higher value capacitors, say 500uF up and up. Choose a resistor so that the capacitor can discharge reasonably slow, for greater accuracy in the results, hence a larger resistor, perhaps 1K to 10K. The smaller the capacitor being measured, the greater the resistance needed so that you can visually see the voltage levels and for accuracy since a small capacitor discharges very rapidly. The problem then will be that that the internal resistance of the meter starts to have greater effect on the overall (ie parallel) resistance in the test circuit. Here is a stopwatch timer on this webpage: www.online-stopwatch.com A good capacitor will hold its voltage for quite a time. A bad one has "leakage" (or current flow) through the dielectric material seperating the plates of the capacitor. It is possible to refurbish a capacitor a bit using a "voltage treatment"... bring the voltage up across ...

Little Bedini motor and BIG solar panel running indoors with just ambient light and no batteries. Light energy is being controlled by a "step down adjustable voltage regulator" which allows energy to build up in a large capacitor before it feeds the motor. Energy coming off the collasping magnetic field of the motor drive coil is recycled back into the motor.

A simple Circuit using 2X lm3914, a cheap transistor and a relay... and a few other bits. you can set the max charge voltage with a small preset potentiometer, when the set voltage has been reached the lm3914 Lights LED 18 (the first red one) and also sends a small base current to the transistor, which then powers the relay coil and turns the ZVS off. when the voltage drops below the set voltage or the capacitor is discharged the power to the relay coil stops and the charging begins again automatically :-D.The transformer is a core stripped from a flyback transformer, with a hand-wound primary and secondary, approx 4.5+4.5 primary turns and roughly 100 turns on the secondary) oh... and before anyone says anything.... (the ZVS is on the Normally Closed contact on the relay) the whole unit/ module/ circuit draws between 3-6A @ 12VDC. Thanks for watching!
