Flyback Transformer High Voltage Fun! Posted by: sparkie21
Video duration: 575 seconds This is my first flyback experiments. The video shows the first arc I made from a flyback transformer, my 'prototype', then it built into a box, and me frying anything I can find! The flyback is from an old black and white portable television. Im hoping to find a better flyback soon, and build a better driver circit. Enjoy! Thanks to the helpers at 4hv.org !!

M0UKD/P QRP with MFJ-9420 and dipole 2m above ground! Posted by: sparkie21
Video duration: 472 seconds Here, we set up a real small station, using the MFJ-9420 20m monoband tranciever, and a dipole antenna at head height in some small trees. Managed to contact a few stations in about half an hour, including PD7X, RU3VV and J5MS. Located in Hornchurch, East London. JO01CM. Hard work sometimes, but its great what you can do with such a simple setup! 73.

First simple hydrogen & oxygen electrolyzer Posted by: sparkie21
Video duration: 105 seconds Here is a very simple cell to produce Hydrogen (66%) and Oxygen (33%) gas, which is highly explosive! Its just made of two 4" stainless steel screws and some salt water. Power is 12v at low current. The last one is a loud bang, doesn't sound loud on the camera :( Related: cell, electrolysis, electrolyzer, explosion, explosive, fuel, gas, h2, h2o, hydrogen, ignite, ignition, oxygen |

MFJ-949E Arcing! Posted by: sparkie21
Video duration: 66 seconds A clip of my MFJ-949E arcing with 70w into a bad antenna at 1850KHz. It flashes on and off because when the radio detects a high vswr, it cuts the power, so the flashes are not continuous. This tuner is fine with normal tuning, but this antenna is way too small for 160m :) Related: amatuer, antenna, arc, arcing, atu, doublet, flashover, ham, m0ukd, matching, mfj, mfj-949e, radio, topband, tuner, unit |
