Not so good for your transistor or power supply. Try to stayĪway from arcing to any of the pins used for coils. Whichever one it arcs like mad to is the one yer looking for. Way to do it is to bring the high voltage line down to the pins and You will not beĪble to locate the high voltage return pin with a multimeter. The high voltage will come out of the fat wire from the top of theįlyback-usually connected to the CRT with a suction cup. Sure you've exhausted all possible combinations. In a potted flyback should work, so don't try new coils until you're Of them with two sets of coils) until it whines (Occasionally I'll find Some of them have a rectifier built in them. Flybacks can be very picky as to coil polarity because Polarity on the first one you switched again. The polarity (switch the leads) of ONE of the coils. If you turn on the power any you don't hear a whine or hum, try reversing Of coils on your flyback, hook them up to the circuit with any polarity. After you have located two independent sets Will need to try the different positions to see which configuration worksīetter for your application. Of coils on the horse-shoe-like configuredĪre more than two pins connected to a single coil in the transformer. Usually ANY two coils in the flyback primary will work. The turn ratio is really not that critical so The flyback circuit diagram calls for two sets of coils: a primaryĬoil and a feedback coil. I wouldĪctually prefer a flyback with the windings potted inside so they don't The flyback don't worry, cause that's where you want them too. If you don't have an old flyback and your windings are potted inside It would probably work evenīETTER than winding your own coils (I've never figured out why everyone If there are at least two sets of coils, you can use If you have an old flyback with removable windings, don't be in such a hurry to remove them and wind you own. I'm not sure why it has a green spot painted on it but it is a very distinguishing I have found two like this and bought another like it on ebay.
The flyback with the highest output voltage and longest arc that I haveĮver seen comes from large modern TV's. But, with a rectified output you can chargeĬapacitors. Although with an unrectified flyback you can drive a plasma globe, Removed the rectifier in a new flyback, the high voltage output will beĪnd will work for a plasma globe whereas a rectified output flyback will The high voltage output may be used for some applications and not others.įor example, if you have an old flyback without rectified output or have Today will have a rectified output (DC) and the primary windings will notīe removable as they are potted in with some kind of polymer.Īny flyback will work in this circuit, but depending on the flyback, Shaped secondarys, removable primarys, no rectification and look like Flyback transformers can be found in any equipment with aĬathode Ray Tube (CRT) like televisions or computer monitors. The main component of the system is the ferrite core flyback Parts, it takes only a few moments to get working. Working as quickly and painlessly as possible.Īs you can see this is a VERY simple circuit and when you have all This page is designed to help you get yours It will make a several thousand-degree continuous 2 cm plasma arc. This circuit uses a common flyback transformer (you probably have more than one in your house right now) to boost typical battery voltages up to the multi-kilovolt range.
