[Grenadier] has a thing for the high voltage and, as you can see, he’s found multiple ways to build the icon of HV toys - a Jacob’s Ladder.
The three look similar, but they use different means of generation the voltages necessary to get a spark to jump through the air. The exhibit on the left uses a neon sign transformer, the one in the middle is based on a transformer from an X-ray machine, and the example to the right uses a microwave oven transformer. [Grenadier] discusses the pros and cons of each method, then links to his in-depth posts about working with each one them. There are also videos for all three. We’ve embedded the video for the microwave oven transformer after the break. That version of the Jacob’s Ladder requires some way to start the spark and in the video he’s doing it manually. There is always the option to add a solenoid to do the job but he does mention that you can’t just let it run because that cheap transformer will burn out before long.
If you like what you see here, perhaps you’ll be entertained when he runs HV through some soda cans.
