This is hands-down the easiest way to make a Jacob’s Ladder, period. All you need is an old TV and a death wish.

The actual tutorial in the video is quite subtle, so here’s a written explanation of exactly what we did:

Instructions:

1. Take apart a CRT TV. Be careful! They can implode if you crack the glass.
2. Rip the circuit board out. This will probably require cutting a few wires.
3. Plug it into the wall, and turn it on. You should hear a high-pitched noise. This is the part where you be EXTREMELY careful.
4. Two of the biggest (usually red) wires will arc up to a few centimeters. These are the wires you want. Don’t get your bare skin near them. Keep your left hand behind your back at all times.
5. Hook the two arcing wires up to a pair of metal rods that are in a long V-shape. Voila! That’s all there is to it.

You might have to initiate the spark by putting something metal between the two wires at the bottom.

DO NOT TRY THIS AT HOME. A SINGLE MISTAKE WILL KILL YOU. The electricity is powerful enough to instantly kill you. Would not recommend.

In this modern world, many aspiring budget DIY enthusiasts will run into a problem: finding used disposable cameras is almost impossible. There are a ton of DIY projects that require disposable cameras. There’s no substitute for them: they contain a specific part that’s almost impossible to find elsewhere.

The Flash Capacitor

The prize inside every disposable camera is the flash circuit. Flash circuits contain two useful parts: a capacitor and its charging circuit. The capacitor is usually between 100-200 µF at around 300-400 Volts. In other words, this thing packs some serious juice. Common uses include tasers and coilguns, both of which you can expect to see on this site at some point. The problem is, disposable cameras are getting harder and harder to come across.

In the old days, one could walk into a local photo development center and simply ask to take all of their used disposable cameras off their hands. In most cases, the store would happily give them away for free. Nowadays it’s not so simple. Few places still develop film on-site. Every single store I’ve tried so far, Walgreens, Walmart, etc., ship the cameras off to be developed somewhere else. Getting free cameras just doesn’t work anymore.

Is there a solution?

There’s no way to solve this problem for everyone. Some people may still have access to film development centers. However, it’s a safe bet to assume that many people have no local access to old disposable cameras in bulk. This is because local stores send the film off to be developed elsewhere. Purchasing new disposable cameras is still possible in many stores, but what idiot would spend upwards of four bucks for something they should be able to get for free? Spending money, obviously, is not an option. The solution? Find out where all of the cameras get sent.

Where do they get sent?

I have no idea. But I’m going to find out. As editor-in-chief and hottest member of Blasted Science, I consider it my duty to solve this mystery. I’ve spent weeks crawling the darkest corners of the internet and contacting companies, gathering all the information I can. Blasted Science will be updated in real time with all the information I find.
