Grenadier's guide to High Voltage

Grenadier's guide to High Voltage

by grenadier

This instructable is a guide to galvanic (not electrostatic) High Voltage sources. I have made sure to cover just about every one of them.

I'm going to be honest with you guys, I wrote this instructable for the laser cutter. However I have deeper motivations than "lolz im gunna cut some stuff"
It's a sad fact to face (well at least for me it is), but the electronics hobby is in decline in America, and there are nowhere near as many hobbyists as there used to be. Many kids wanted to make a crystal radio in the 20th century and a lot of them did. Many of them left it at that, but some kids went further and bought a transformer a couple triodes and components at the local store, then made a vacuum tube radio.  Often of those kids became electronics hobbyists, and a some of them even became electrical engineers.

That was truly the golden age of hobby electronics, but now most kids don't even know how a radio works let alone how to make one or any other circuit for that matter. Out of the 2500 people at my school, I'm the only one that even knows how a mosfet works (seriously!). I don't like that ratio, so I have made it my personal mission to get the electronics hobby booming again. Hopefully to the point where radioshack can actually start selling components again and not just phones and cameras. I intend to do this by getting kids and young adults interested in electronics again, and I have chosen to do this using 3 methods:

Method one will be to make electronics interesting again. Sure the electronic dice and radio kits are alright I suppose, but they sure didn't get me excited and they sure won't get the average x-box playing kid excited either. So I plan on selling interesting kits such as induction heaters and the like, and selling them as cheap as I can so the average kid can actually afford them! I'll need PCBs for these kits and I looked at a couple boardhouses; the prices are ridiculous! The only way to make the kits affordable to a kid is to make my own PCBs, and to make a whole bunch of them easily. The epilog will allow me to do that.

Method two is to provide tools to these kids at low prices. Sure they can always go and get one of those crapshack irons for $10, but honestly anyone who has used them knows they suck big time. I intend to sell tools such as temp controlled weller tipped irons at reasonable prices, hopefully in the range of $20. It can be done, but I'll need cases to house the electronics and the zing will allow me to make them.

Method three is to provide services to these new hobbyists such as case and PCB fabrication, and to do it at a low cost. We all know that PCB and part fab is rather pricey, but I intend to change that. I'll make it cheap enough that a child could afford it and make their projects look nice, and the zing will allow me to do both. My only power tool at the moment is a dremel, and although some may disagree with me I don't think that is good enough.

I don't intend to make much profit on this endeavor and any profit that's had will be used to develop new kits, and to buy a new laser tube when the one in the zing dies, because CO2 lasers do die. It's going to take a lot of effort on my part to accomplish this task, but I know that I can do it. I just need the the tools to do so...

Although if this contest is like the last one where voting is partially based on views, looking at the other entries I feel as if I might be on a fool's errand. We all know that the laws of physics state that something featuring titteez is going to get a lot more views than anything scientific...

Well I ask of you, please vote for me in this contest. You can even login with facebook if you don't have an instructables account. Please post this instructable on your blog or website, tumblr, twitter or facebook page, and please help me start my mission!
