Hey

Well good morning everyone. How is your Thursday going? I had to get up earlier this morning. Its probably normal for most people but getting up at 6 is early for us. Is that early for you? I have been stressing lately. I have a million things to do before we go see my sick Grandpa, and I feel like there isn’t enough time. Do you guys feel that? I noticed now that I am an adult that time is going by so fast. I remember as a kid time seemed to crawl by. Now it speeds by like the Crimson Comet.

On to tech thursday!!


Tech

As a kid of the 90s I got to see many cult classics. Of those wonderful movies my favorite has to be Back to the Future.

I remember watching the movie as a kid thinking how awesome all those flying cars and hover-boards and everything else were. Not much more thought went into them. They were just awesome and I wanted one.

Now here I am years later, and we are around a year away from the time Marty and Doc travel to in the future.

Our technology is way more advanced than it was even 20 years ago, but yet our present still is a ways off from some of the things envisioned in the movie. But how far off are we?

Maye only a year for one of the things.

 The Hoverboard

I love that Hendo’s goal is for it to be out next October 21, “in time for the arrival of Marty.”

The current prototype can hold up to 300 lbs. They are hoping for future versions to be able to hold 500 lbs.

It hovers around an half inch.

With 52 days left for their Kickstarter Campaign they have already reached their goal of $250,000.

Do you have a great idea for this invention? On their kickstarter page they state they are giving away 3 of the whitebox developer kits.

The magic behind the hoverboard lies in its four disc-shaped hover engines. These create a special magnetic field which literally pushes against itself, generating the lift which levitates our board off the ground.

While our hoverboard is primarily intended to be self-propelled, the actions which stabilize it can also be used to drive it forward by altering the projected force on the surface below.

Currently, this surface needs to be a non-ferromagnetic conductor.  Right now we use commonly available metals in simple sheets, but we are working on new compounds and new configurations to maximize our technology and minimize costs. “Hendo HoverBoards”

Levitation using magnets seems simple – just put one magnet over another, same poles facing, and the top one will float. Voila, right?  Sadly, as we all find out (usually as heartbroken little kids) this never works. Due to something called Earnshaw’s Theorem, a stable static equilibrium between two magnets is impossible. There have been a number of ways around this, but none have proven feasible enough for everyday applications. Until now.

Lenz’s law explains how eddy currents are created when magnets are moved relative to a conductive material.  These eddy currents in turn create an opposing magnetic field in the conductor.  Our core technology, which we call Magnetic Field Architecture (MFA™), focuses this field more efficiently. 

As with other Kickstarter campaigns  Hendo also offers many incentives, not sure if thats the term, for those that donate to their campaign. I have seen a few and I must say I think their incentives are the best I have seen.

$59.00 will get your name etched onto a plague for the skate park.

For $100.00 you can have a 5 minute ride on their hoverboard.

I couldn’t help but look at the backers there were 10 people at the time of me writting this that donated 10,000.00 which means they get their very own hoverboard.

Are you excited for the day we can ride these around?


Facts

How did they do the BTTF scene?

It was created by suspending actors from a rig on the back of a truck and driving them around Courthouse Square (a fixed shooting location in Universal’s back lot in Hollywood) on hoverboards that were nailed or glued to their feet to appear as if they were floating in the middle of nowhere. Scenes where the hoverboards seem to jump up and snap onto the riders’ feet were created with the help of rare earth magnets secreted in the actors’ shoes. Closeups were effected by posing hoverboard-riding actors in front of a blue screen, then afterwards melding these shots with footage of the background scene. Snopes

I want this technology.

Have a great day everyone. 🙂
