LEGO Bridge Girder Builder

0

It will never cease to amaze me with the ingenuity of people when it comes to LEGO contraptions. I’ve never seen one of these full size bridge girder movers, but watching this LEGO version makes me amazed at how humans have been able to make machines to make life easier. Especially since this machine is … Continued

Marbles!

0

A Crap ton of Marbles. 11,000 according to the video description to be sure.  I’m sure there are more there, that large trey at the end seemed like the markers were past the 10,000 point before it flipped.  There weren’t that many different paths for the marbles to go though.  I think it would have … Continued

I do Nothing

0

For a period of 15 years starting in 1948 Lawrence Wahlstrom, the retired clock maker and by all means armature engineer, added many gears to a old WW2 bomb sight.  The actual number of gears is unknown, he stopped counting, or lost count, or both.  It’s over 700 though. What do all these gears do?

Wooden Engineering Equipement

0

Japanese woodworker Kinohaguruma makes some of the the coolest works of wooded engineering I have ever seen. Here’s the first video that introduced me to him, a wooden excavator: See how the entire thing is made of wood.  There’s a bunch of different gears, and different transmissions and gear boxes that change what is actually being … Continued

Controllable Bubbles

0

Part of the fun of bubbles is not knowing what you’re going to get.  Not knowing how many, or how large, or how long the bubbles are going to be.  They are unpredictable.  Gordon Kirkwood decided to take the unpredictability out of them.  He made what he calls the CNC Bubble Iris.  The entire thing … Continued

Gears

Gear reduction is pretty basic mechanical engineering.  It’s used everywhere and in everything.  It’s a great way to give a person an introduction as how various machines work, and how to increase torque, or speed.  The above contraption, made by Oskar van Deventer, has an astonishing gear ratio of 11,373,076 to 1.  That means, the … Continued

Over-Engineered Door

0

How can you over-engineer a door you might ask?  Well, that’s a question answered by Matharoo Associates.  They’ve designed, and built this interesting door above.  It’s made of 40 individual sections of Teak, with 160 pulleys, 80 ball bearings, and a wire rope connected to a counterweight.  Opening the door happens with a wave of … Continued

How a Jet Engine Works

0

  I featured Animagraffs before, that time it was how a gun works.  Now we see how a Jet Engine works. The Afterburner is the important part.  It’s what allows the F-15 to be such an effective fighter.  Not just the F-15 though, all fighters use it, but the F-15 is the best fighter ever … Continued

Rings of Saturn Ride

1

I’m not one for amusement park rides, in fact, outside of Rollercoaster Tycoon, I hate amusement parks.  I wouldn’t even think of going near this ride, but I would love to see it in full sized action.  It honestly looks like the inventor, Thomas Casey, knows exactly what he’s doing, and is some strange cross … Continued

Pencil Balancing

0

I must say that is an impressive feat of engineering to achieve an almost useless thing.  But I’m pretty sure there are all sorts of different applications where it can be used to stabilize equipment, and things.  Actually, with some refinements, if he could get the Pencil to stay absolutely perfectly straight, this could have … Continued
