How to make a high voltage DC generator/power supply using a flyback transformer and a Cockcroft-Walton voltage multiplier or 30kV tripler. This one generates up to 30 kilovolts with milliamps of current. I demonstrate it using sparking and by powering a lifter or ionocraft.\r<br>\r<br>It uses:\r<br>- 220 ohm, 3 watt resistor\r<br>- 27 ohm, 2 watt resistor\r<br>- 4700 microfarad, 35 volt electrolytic capacitor\r<br>- two 2N3055 power transistors\r<br>- flyback transformer with no additional electronics attached to it\r<br>- 30kV Cockcroft-Walton voltage multiplier, also known as a 30kV tripler\r<br>\r<br>I show how to power it using my homemade 24 volt power supply, a simple wall adapter and a laptop power supply.\r<br>\r<br>For a video showing how I fixed this power supply when it broke, watch this:\r<br>\r<br>\r<br>For details about my homemade 24 volt power supply, go to:\r<br>\r<br>\r<br>For my webpage about this high voltage power supply, go to:\r<br>\r<br>\r<br>If you want to make your own tripler/Cockcroft Walton voltage multiplier, see my webpage here as a starting point:\r<br>\r<br>\r<br>For a flyback transformer without a built-in diode (the one for this power supply must not have a built-in diode) see here:\r<br>\r<br>The Sanyo F 0241 listed there might be a good one, but I cant say for sure.\r<br>\r<br>WARNING: This power supply delivers a lethal amount of current, in the milliamps. It is not like a small homemade Van de Graaff generator whose current is in the microamps. Notice the precaution of using a grounded discharge stick in this video. Do not make this one unless you understand how to use it safely.\r<br>\r<br>Also watch:\r<br>\r<br>How to mount/attach transistor to heatsink (2N3055)\r<br>\r<br>\r<br>Lifter Voltage/Current and Smoke/Aiflow Test Measurements\r<br>\r<br>\r<br>How to Make High Voltage Capacitors - Homemade/DIY Capacitors\r<br>\r<br>\r<br>Follow behind-the-scenes on:\r<br>\r<br>Twitter \r<br>\r<br>Google+ \r<br>\r<br>Facebook \r<br>\r<br>\r<br>\r<br>Music used throughout:\r<br>Bicycle Kevin MacLeod (incompetech.com)\r<br>Licensed under Creative Commons: By Attribution 3.0\r<br>\r<br>ISRC: USUAN1100870
