Spin Stabilized Rocket

This Spin Stabilized Rocket looks really cool. The three 13mm rocket motor tubes are all angled to that it spins the rocket as it flies. You can see the rocket fly in the video below. Sure is a cool idea but I am not sure the result was optimal, but I am not sure if it is more predictable than motors installed straight in though.

How did this Nail Get in the Wood

at 1:19 am. Filed under Crazy Hacks, DIY Hacks

nail through wood

 

Before you watch the video below have a close look at the picture above and guess how this was done. There are 3 slots cut into a piece of wood, there is a real solid nail placed in the wood. Each section of wood including the outer sections are solid (just as it looks). You would not be able to remove the nail by sliding it. This was a real puzzler for me and I wouldn’t have guessed how it was done without watching the video…

Leave a guess in the comments if you think you have figured it out. You will probably need to try to not look at any other comments that may exist. I am curious how many people get it?

DIY Pop Bottle Airsoft Machine Gun

at 2:19 am. Filed under Crazy Hacks

 

This DIY Pop Bottle Airsoft Machine Gun should cost $10 to $15, doesn’t use any parts that can’t be found at your local hardware store and should take less then an hour to build. Best of all if you have a compressor handy you can shoot the thing to your hearts desire. You might run out of targets to shoot in a hurry though since it has a very impressive fire rate!

Titan Arm – Super Human Strength Arm

Titan Arm - Super Human Strength Arm 

If you would like to be a super hero for a day, this Titan Arm can make it happen! They have milled the exoskeleton system out of 6061-T6 aluminum. It hasn’t been all smooth sailing, check out this video of the mill crashing when some wrong coordinates were entered by accident. The technology and testing behind the arm is extensive. They have attempted to design it in such a way that it feels intuitive to use.

“One way of creating a natural user experience is to give a quick, smooth response to the user input.  This is no small feat; how can you tell when a user requires additional strength?  Electromyography is a potential solution.  Electromyography, or EMG, is a way of sensing muscle activity through electrical signals.  When muscles are activated by the brain, an electrical potential can be measured in the range of 50uV to 30 mV.  By amplifying and filtering the signals, it’s possible to read and decompose the signals.  When the muscles are inactive, the electrical potential is low; however, when lifting an object, the electrical potential rises.”

Laser Cutting 3D Objects

 Laser Cutting 3D Objects

 

When think of what a laser cutter can do you normally think of cutting things and etching surfaces. I never would have thought of making something 3D other than making notches that can link together. This video shows a technique that holds the material being worked over the main laser cutter bed using some stilts. Cuts are made in acrylic and since acrylic bends when heated the laser is used to slowly warm the material where it is needed to be bent. Since the work is sitting off the bed it can droop when heated. To see more information on this Laser Cutting 3D Objects method have a look here.

Pulse Jet Go Cart

Pulse Jet Go Cart_1

 

MrBen527 has been spending some time developing a cool looking Pulse Jet Go Cart, I am a bit surprised at how receptive his neighbors are. I think his creation would be a bit more annoying than a barking dog. Watch this video to see his creation in action. MrBen527 is also creating a new version of the engine that can be seen here, this one should put on a good show. I am thinking that if you wipe out all is fine as long as the red hot engine doesn’t land on top of you!

Not sure if this one is louder than the Pulse Jet Go Cart we saw back in 2008?

Mantis Hexapod Walking Machine by Matt Denton _7

 

We have featured Matt Denton’s hexapod designs in the past. He has been spending some time working on a project that is a bit bigger than the previous ones! His new design which has been 4 years in the making called Mantis is a Hexapod Walking Machine. He has taken lots of pictures in the Facebook page (a few can be seen below). This video done by Daily Planet talks about Matt and his machines.

“After four years intensive R&D, inspiration, design and build, Micromagic Systems is proud to unveil Mantis — the biggest, all-terrain operational hexapod robot in the world.

This 2.2-litre Turbo Diesel-powered, British-designed and -built walking machine can be piloted or remote WiFi-controlled, stands 2.8 metres high with a five meter working envelope and weighing in at just under two tonnes.”
