DIY 3D LED POV

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 know I would have a difficult time figuring out how to get power to the LEDs, let alone a program to control them all.  No, I will stick with old fashioned wood working thank you very much.

Compressed Water Rocket

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 empty 2 liter bottles half full of water in my back yard.  It was a process to see how much water would give us the greatest height.  I never put a parachute on it though, this was 20 years ago, kids had stronger bodies back then, it’s a scientific fact.

Fully Auto Snowball Machine Gun

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 like it.  Like I said though, hopefully this winter will get nice and snowy so that we can implement it.

DIY CNC

 

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 so sure how powerful the motors are in these drives though, they probably wouldn’t be able to handle actually cutting something.  That’s unfortunate.

DIY EMP

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 to make it as bomb like as possible so that you get on all the lists.  In reality though, it doesn’t look like it has any lasting effects on things.  Except that Android phone.  I don’t know if he should have cut that out because he obviously broke something, or if he kept it in to show that it really works.

Be careful, don’t do this at home, and I don’t know anything about anything.

Dangerous Woodworking

https://youtu.be/H3cXSICfMzM

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 it needs to be, but for the video, it should have been sped up.

Destroying things with Electricity

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:

capacitors

According to math, all of these wired up in parallel like this gives 2180J of potential, which if I remember, is quite alot.  Here you can see what happens when all of that energy is released at once into a pencil.  Hint, it’s not good.

After the click you can watch an extra awesome video.  Trust me.

DIY Nitrocellulose Cannon

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, everything this guy is doing looks professionally made.  I’m not sure I would have the wires as exposed as that, but hey, it’s not going on my desk.

Exploding Balloons

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 with this substance.  All in all it’s pretty standard stuff.  The best bit however is when they shoot it with a golf ball.  Oh, did I mention that they have a high speed camera set up filming this?  They do, that’s what makes this so fun.  And the golf ball shot, that’s awesome.

Epoxied Wire Art

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 bracelet, which is why I’ve embedded to that video instead of the bracelet.  Look at the distortion through the curved edges of the bowl.  Isn’t that cool looking?  I think so.  It’s not the most environmental friendly way to get rid of this type of stuff, but it is re-using it.
