Making a High Voltage Generator which runs off a 9V battery

 This device is easily capable on sending hot arcs over 1cm, and is completely wireless. It runs on a normal 9V battery and is incredibly reliable, and waterproof. This post will show you the methods of making it.


To begin, you will need to heart of the system - a module that converts the 9v into a high voltage, low current output. The High Voltage Generator (HVG) can be bought from Amazon, thus saving the need for any complicated electronics.




The next item that's needed is a switch, or in my case, two switches. I used a toggle switch to arm the device for safety, and a press switch to momentarily send power to the HVG. Finally, as a personal touch, I used a 9v to wire adaptor to make battery changes easier - but this is purely optional.

To begin the build, you want to wire everything together. I like to use wire connector blocks, as they insulate all the connections. Below is the diagram, and below that is the schematic.




In real life, this wiring looks like this:

Then use a hot nail to make 4 holes in the top of a container


The larger holes accommodate the switches; the screws are tightened to secure the switches to the lid.


Next, you can insert the screws into the smaller holes. Wrap a bit of foil around the electrode output of the HVG and tighten the nut onto them to provide a firm connection, like so:


The contraption should now look like this:


To finish, simply close the lid of the container. To stop any rattling, I hot glued the battery and HVG to the floor of the container. The final product looks like this. The two metal sticks coming out the end are the electrodes to the 40kV output. To prevent burning out, I placed them close enough to arc between them. When a sparkplug is connected, this arcing will stop.

Making an oil siphoned rocket-based burner

This essay explores the concept of using siphoning as a fuel pump system, examining its efficiency, practicality, and potential benefits. Below is the initial sketch for the burner. Fuel, in this case vegetable oil, is stored in a reservoir. It is then siphoned down a tube into an atomiser, which is then held in front of a stream of low speed, high pressure air. This mixes thoroughly with he oxygen and makes a mixture suitable for combustion. This is then lit by hot gases expelled from the mouth of the rocket, and then exits, creating thrust and massive amounts of heat. The Siphoning Principle Siphoning is a natural phenomenon that occurs when a liquid flows between two containers at different elevations due to the force of gravity. It involves a tube through which the liquid moves, creating a vacuum that draws the liquid upward and overcomes the force of gravity. In the context of fuel burners, this principle can be harnessed to transport fuel from a storage tank to the burner unit wi

Making Iron Oxide through cheap electrolysis

Iron oxide (Fe2O3) can easily be made through electrolysis. The basic idea is to pass a current through water with iron electrodes. The water splits into hydrogen and oxygen. The oxygen then binds to the iron electrode, turning the Fe2+ into the iron oxide. This method produces very red iron oxide, with an oxidation state of 3+. Firstly, you will need a power supply, which is the most inaccessible aspect of this project. I used an old laptop power supply, with the ends connected a large clip and a piece of old pipe. This produced 19V at 3 amps, which is more than enough. The next issue is that water is not conductive. To combat this, I used table salt, though some people do not like to use this as a by-product of the reaction is chlorine. Because of this, I only ran this experiment in a well ventilated attic. I used a large plastic bucket to perform this experiment. It is important that the bucket itself is not conductive, or it will short out the current, and no power will actually go
