DIY 3D LED POV

0

Is that enough acronyms in the title?  No, I think I can get a few more, don’t you?  I find the rotating LED signs interesting, though useless.  I can’t think of a reason to make one, and as such, I don’t really want to spend too much of my already valuable time making one.  I … Continued

Compressed Water Rocket

0

Often called a Pop bottle rocket, or something similar.  This is something else entirely.  This is a true multi-stage rocket powered by water and air that reaches up to 800 feet in altitude.  I particularly like the Red, White, and Blue “exhaust” I remember spending Saturday afternoons with the car compressor and a cork launching … Continued

Fully Auto Snowball Machine Gun

0

Hopefully this coming winter will be better then last and something like a the above video.  Hopefully… The system itself is pretty simple, take a back mounted leaf blower attach some cut PVC with a plunger on it to a Y on the hose.  Then push some pre-made snowballs in and watch the carnage.  I … Continued

DIY CNC

0

  Technically this is a computer numerical controlled machine, though it’s not the same thing that most people think of when they hear CNC Machine.  It looks pretty easy to build.  There’s not much to it.  Anyone remotely interested in computers has a plethora of old unused optical drives that they can re-purpose.  I’m not … Continued

DIY EMP

0

Have you ever wanted to make your own Electromagnetic Pulse?  I have, unfortunately the most reliable way to produce an efficient one is via a nuclear explosion.  Or, maybe I just want to see a nuclear explosion for myself.  Either way, you can create your own EMP generator by following the above video.  Be sure … Continued

Dangerous Woodworking

0

There’s some pretty neat machines in here that mill wood, work with wood, and do all sorts of things to wood.  I like the bread cutting device 3 or 4 minutes in, that thing looks inefficient, but cool.  Cutting that giant cedar log down just off center though took forever.  It makes sense how slow … Continued

Destroying things with Electricity

0

Electricity is dangerous.  If lightning wasn’t proof enough of that, here you can watch as someone for reasons unknown (otherwise known as because I can), decided to connect 16 high capacity capacitors together.  For serious, look at the size of these things: According to math, all of these wired up in parallel like this gives 2180J … Continued

DIY Nitrocellulose Cannon

0

Nitrocellulose is just a fancy word for flash paper.  But Youtuber NightHawkInLight has created a pretty simple cannon that he used to fire this flash paper.  It’s all bark and no bite, but that show is pretty impressive, as is the video below.  The entire cannon is very well made, especially the curved hinge.  Actually, … Continued

Exploding Balloons

0

TheBackyardScientist has set up some backyard experiments with balloons filled with cornstarch and water. This mixture forms what is called a non-newtonian fluid.  It’s liquid when at rest, but hit it with a sharp, quick force and it turns into a solid.  In the video above they compare balloons filled with water to those filled … Continued

Epoxied Wire Art

0

Epoxy is a magical substance.  You can make all sorts of cool things with it if you’re willing to experiment.  Using some old wires, cat-5, telephone, and plain copper.  They actually look pretty good, especially with the randomness of the wires as they are placed within the epoxy. I like the Bowl better then the … Continued
