Various electrochemical reactions requires that anodes do not degrade when used. Carbon is cheap, but degrades easily and platinum is extremely expensive. In a previous video, you learned "How to make cobalt and manganese nitrates", and you saw that titanium could be used as a cathode, but not as an anode due to an effect called passivation.
In order to remove car dents with reusable electrode, you will need to remove all of the paint first. For this project, you will need a sander, an electrode, and a hammer or mallet.
Hi Guys! I am Sara...I got run over by a truck (drunk driver, not on purpose) and one of my physical therapy tools is a TENS Unit- it sends electric shocks, level and type to be decided by user, to body parts via electrodes. When I first got it, I was using it and accidentally turned it WAY UP instead of off! I sends a crazy intense shock. My first thought, after I stopped laughing my electrified ass off, was of you Jackass guys :) SO...
In order to properly strike an arc with a welding electrode, the idea is to make contact between the metal of the arc being welded and the electrode that is doing the welding. While practice is the best way to learn how to weld, some tips can give a solid beginning. Watch this video welding tutorial and learn how to strike an arc with a welding electrode.
Watch this science video tutorial from Nurd Rage on how to make copper sulfate from copper and sulfuric acid in three ways. They show you how to make copper sulfate from copper and sulfuric acid using two chemical methods and one electrochemical method.
You already know how to make sulfuric acid with the metabisulfite and oxidizer method and you saw how to make copper sulfate from copper and sulfuric acid, so now try making sulfuric acid with these two in mind… with sulfuric acid by electrolysis of copper using an inert anode.
Arc welding is a type of welding that uses a power supply to create an electric arch between an electrode (electric conductor) and a base material to melt the metals at the welding point. While you can certainly purchase a welder for your car shop or jewelry making business, you can actually save some money in that department by making your own.
If you want to know the best way to get an accurate pH measurement, this shows the lab equipment needed and the processes used. When doing chemical reactions, sometimes the acidity or the basicity is important. This is usually defined as pH and measuring it can be very useful for getting the reaction right. There are a few ways to measure pH, and the simplest, cheapest, most reliable method is paper. But that's not all. See a whole lot of ways in this two-part video.
Watch this science video tutorial from Nurd Rage on how to restore silver with electrochemistry. You can restore old silver with aluminum foil or a battery by simple electrochemistry.
This video shows you the proper way to clean your spark plug to ensure it is working efficiently. A step by step written guide.
Last time, I showed how to start putting together an AC arc welder from scavenged microwave parts, focusing on the transformer modifications. Now, I'll show you how to finish up your DIY stick welding machine by fixing up the electrical system and performing the finishing touches.
In this soldering tip video brought to you by BEST, Inc. Norman Mier demonstrates Metal Electrode Leadless Face Diodes removal using the tweezer method with tin-lead solder.
A typical resistance spot welder can range in price from about $200-$800, but with a little resourcefulness and a bit of free time, you can make one like this for about $10 or less.
Sony Corp. is working on new battery technology that the company says would have a 40% longer life than a lithium-ion battery of the same size. Sony is planning to have the higher-capacity batteries on the market around 2020.
Some bacteria can already do it—generate electric current, that is—and those microbes are called "electrogenic." Now, thanks to the work of a research group from the University of California, Santa Barbara, we know how to easily turn non-electrogenic bacteria into electricity producers.
Who's ready to let future Facebook augmented reality smartglasses read their brain? Well, ready or not, the tech giant is making progress in the area of brain control interfaces (BCI) by funding research.
About a third of the methane released into the environment comes from the production and transport of natural gas. The gas leaks as it moves along the transport chain from gas wellheads to market.
A deck of cards may be a magician's best way to demonstrate his or her's sleight of hand, but for the prankster, it's the perfect way to deliver a shocking 300 volts of electricity! And that's exactly what I'm going to show you how to do today. Stuart Edge used it in his "Electric Shock Kissing Prank" to show the ladies how a man can really put the sparks in a kiss.
Here is an educational video for ART (Advanced Robotic Technology) Plasma customers. The HDP Plasma SX Profile Cutter is designed for heavy duty manufacturing environments where power, precision, speed, quality low cost, productivity, and durability are demanded by business owners. See in these sixteen videos how it works, from the inside out, and another video on what it actually is.
In the perpetual search for a renewable and convenient energy source, our bacterial friends have once again stolen the limelight.
In a previous project, I showed how to build an electrical Jacob's ladder using an old microwave oven transformer (MOT). In this project, I modified the secondary coil on the MOT, which converts it from a high voltage/low current device into a low voltage/high current metal melter!
Valentine's Day is almost here, and if you're like me, you're scurrying to do something special for your mate. The standard chocolates and flowers just isn't cutting it anymore, and you can only make so many homemade cards before it becomes banal and meaningless. So, what can you do that shows you put some work into it, while not breaking the bank?
I was in college, and my 15-inch Sony Vaio laptop was my prized possession. It was my first PC and probably the most important thing I brought with me to my dorm — it was both how I completed my assignments and my primary source of entertainment. How could it turn its back on me in my time of need?
As promised earlier this year, Neurable has introduced limited beta of a Unity-compatible software developer's kit (SDK) for its brain control interface (BCI) for augmented and virtual reality.

Science-fiction writer Jules Verne predicted many scientific breakthroughs, including the moon landing, tasers, and nuclear submarines. In his 1874 book The Mysterious Island, Verne writes:
This highly educational video geared towards scientists will show you how to generate AC electrokinetic phenomena by microelectrode structures.
Relax PETA, it's not as evil as it looks (although those neural electrode implants do look painful).
The newest fuel alternative on the horizon? Pee. U.S. researchers have been experimenting with using urine as a method of producing hydrogen. Not only could this virtually free and readily available resource possibly power automobiles, but it could also aid in the clean up of municipal wastewater.
As some of you Mad Science readers will remember, we recently covered the separation of water into hydrogen and oxygen using electrolysis. Passing a current through water can rend it apart, but we can also recombine that oxygen and hydrogen to make electricity! This is the principle behind those vehicles run by hydrogen fuel cell engines.
Lying is awesome. From a very young age, children learn that flat out denying the truth gets you out of trouble and helps keep you calm in the face of horror. But what happens when you just have to know if someone, say, used your toothbrush? You could ask them to take an expensive and arduous polygraph test.
