Project History & More Info:

To all the MythBusters fans out there .. No offense to MythBusters is intended. I realize they busted the HouseholdHacker project that claimed using aluminum foil and a penny would work. However, I was motivated on this project mainly by the statement that “a paper plate speaker for less than a dollar, really is just too good to be true”.

This video is meant to be a fun way to show it can be done under $1. If copper wire is an issue, the TV hacking, and wire from the sump pump motor is to demonstrate that copper wire is everywhere, not just in stores.

The idea of making a speaker out of a paper plate is intriguing, and to do it for under a buck is even better. But first, we’ll have to understand how a speaker works.

It’s lack of a few more modern tech features will show it’s age, but the 2013 updates significantly refresh the car and for those of you who want a stylish sedan like this, but find an Audi A7 or BMW 640i Gran Coupe out of your price range. Head over to your local VW dealer and drive this model.

High amperage electricity can easily melt metal! In this video you’ll learn step by step how to modify a microwave oven transformer into a high-current device that can pump out 800 amps of electrical current. This is how to build The Metal Melter!

WARNING:

Burning galvanized metal may release toxic Zinc Oxide fumes. This project is extremely dangerous and should not be attempted without adult supervision and adequate training. Misuse, or careless use, of tools or projects may result in severe electric shock, cardiac arrest, serious injury, permanent damage to equipment and property, and/or death.

Project History & More Info:

By modifying the secondary coil on a MOT, the transformer is converted from a high voltage/low current device into a low voltage/high current metal melter. The first MOT in the video produces just over 500 amps, and the second one is capable of nearly 800 amps.

Any metal that can conduct such low voltage electricity acts as a resistor between the electrode wires, and heats up due to the extreme electrical friction.

A practical application of this modified transformer is shown in another video on how to make a spot welder. This way, the high current can be directed to one focused location to fuse sheets of metal together on contact.

Meet Acura’s previous best selling model, the TL. Hit with the ugly stick for the 2009 model year, it severely hampered sales of Acura once best selling luxury sedan in the segment. The 2012 refreshed helped to bring buyers back into showrooms however, with a next generation due for 2014. Acura really needs another home run, similar to what it got in 2004 with the new TL and TSX at the time.

Light a survival fire with your pee. If you’re into survival skills and fire-making techniques, this is a great trick to know if urine trouble.

Dual Survival – Urine Ignition http://youtu.be/SwW5hwX47MY

WARNING:

Use of this video content is at your own risk.

Project History & More Info:

This is a great trick to know if urine trouble.

If clear liquids can be conformed to the shape of a sphere, sunlight can be refracted through the fluid and the energy can be focused to a point.

Clear water is one of the best choices because it doesn’t absorb any of the suns energy, so more heat is transferred to the tinder. Colored liquids, or liquids in colored bottles can still work, but energy is lost, and that could be the difference between getting tinder ignition or not.

After making fires with various water bottles, and posting my first video on it in 2010, someone commented and said they saw a guy on Dual Survival do it with his urine. That sounded pretty amazing to me, so I looked up the link on YouTube and saw the clip.

It seemed like he had quite a bit of trouble actually getting his fire going, and I thought that if I were ever in a survival situation like that, the last thing I would want to be doing is trying for hours how to figure out how it works. It’s better to be prepared beforehand.

This video comes after many experiments of playing with various techniques. I found that using plastic wrap and urine made a combination that gave great success, and within a minute or two I could have a flame! When done correctly, it works just the same as a magnifying glass.

Practicing with the amount of pressure is key, because too little and you won’t have a good lens. Too much, and the plastic bursts and you’re soaking wet.

FAQ’s:

Q: Why did I wrap an apple in plastic wrap?

A: Of course the video is fictional, however the survival techniques portrayed are real. I wrapped my apple with plastic wrap because I’ve seen it done before at hotels, and I wanted to give an example of how random resources can be used as tools. If you don’t wrap your apples in plastic wrap, perhaps you wrap your sandwich, or various other food items? The plastic baggie holding the celery can also be used in a very similar manner.

Q: Why did I use a page from the map for tinder instead of grass or leaves?

A: This liquid lens technique will light any tinder that could be lit with a magnifying glass, since that’s what it is in essence. I used a piece of paper as an example because most people have access to that as a material they could practice with. I chose paper because it’s easily duplicatable by anyone wanting to try.

Q: Why does the urine change color just before I light the tinder? Did I cheat?

A: The urine changes color mid video, and that’s because when I went to re-set my camera for a different angled shot, I dropped the first sack of urine. Awkward to hold the sack, and adjust the camera on rocky terrain at the same time. I lost my urine and had to wait for another round .. which, by that point was more hydrated because of all the water I’d drank earlier, and therefore more clear in color. In either case, I have the same success igniting tinder with either liquid lens so the difference made by the color is negligible.

Did you know there’s a way to start a fire by squishing air? In this project we’re building a tool that does exactly that, and with a little bit of resourcefulness, we can make this for under $1.00. This tool is completely see through, so you can witness the ignition first hand!

Project History & More Info:

A fire piston, or a “slam rod fire starter” as I sometimes call it, is a device used centuries ago to kindle fire. It works because rapid compression heats the air in the chamber to the ignition point of tinders, such as char cloth. The tinder can then be used to ignite kindling, and develop a flame.

It’s thought that the fire piston may have inspired Rudolf Diesel in his creation of the diesel engine around 1892.

I had a fire piston I made out of copper tubing, but I wanted to make one out of clear acrylic so I could actually see the ignition of the tinder. It seemed it mystery how, or when, it actually lit, and I wanted to see.

FINDING ACRYLIC: I used google.com to find different plastics companies in my area, and called around until I found one that sold acrylic tubing and rods to the public. I went for a visit, and luckily they had some lengths of scrap tubing they couldn’t sell. I asked them if I could use it for a science project, and they gave it to me for free.

The tubing I used was 1/2″ inside diameter, and the rod was 1/2″ outside diameter – clear acrylic.

This piston was given to a subscriber, as part of a contest I held in celebration of 10,000 subscribers on my YouTube channel.

See more information on the fire piston on Wikipedia; http://en.wikipedia.org/wiki/Fire_piston

Today, it remains the companies best seller and most known model. Personally, we think the first generation has better driving dynamics but the second generation has a much more luxury car feeling interior. Hopefully, Infiniti will figure out how to blend the two with the upcoming third generation.

For this project I used items from around the house to create a pyrotechnic time-delay. Here’s how to make a simple form of a slow burning fuse, because when experimenting with homemade pyrotechnics, you don’t want to be too close if your composition explodes.

Ignition of an incendiary or explosive material may not be legal in your area, so check local laws before attempting. Use of this video content is at your own risk.

Project History & More Info:

Similar to the recipes I tried for rocket fuel and smoke flares in previous videos, I’m using a 60/40 mix of KNO3 and white table sugar by weight. This time I’m making a 60 gram batch, adding it to boiling water, and stirring it in until it all dissolves.

Fuses were homemade by soaking 12 feet of 100% cotton yarn in the solution as the rest of the water evaporated out, then placed on a cookie sheet and baked in an oven at 300ºF for 20 minutes.

These types of devices may not be legal to make or use in your area, so check local laws before attempting to duplicate this project, and as always, be safe and aware of your environment before igniting anything flammable!
