Heavy Lifting Copters

at 11:39 pm. Filed under Funny Hacks, Insane Equipment, What Were They Thinking

 

Hobby King had a great plan to get people building big lifting copters. They call it the Beer Lift but water is used as a substitute although I am sure an equal weight of beer is weighting behind the scenes for enjoying after the competition. The last video isn’t a heavy lift but make sure you watch what happens at 2:20, that is some good flying!

Waterproof Electrical/Electronic Spray

at 9:42 am. Filed under What Were They Thinking

 

This Waterproof Electrical/Electronic Spray by Nano Protech looks amazing. Not exactly sure I understand how it works though. At first I thought it sealed the electronics but they demonstrate a socket and light bulb still operating after they are coated and then screwed together. Obviously the coating isn’t an insulator since the bulb is still making contact and it isn’t a conductor since it isn’t shorting out. I would be curious if they salted up that water well if the results would be the same since I am not certain that a light bulb socket would arc in distilled water? I wonder if the coating is simply being scratched through by the contacts on the bulb to make the contact.

“Based on a new kind of nano-zeolithe-technology with a slightly oily consistency, the coating crawls under rust,  oxidations  and humidity, forming a three dimensional multifunctional protective barrier network at the interface. Fills micro cavities (in circuit boards, micro circuitry, electric coils etc.). Powerful capillary effect allows the product to penetrate inside the blocks without dismantling. Excellent water repellent properties and low surface tension allow it to form a thin protective coating penetrating under the water layer. After spraying, a protective coating forms on the surface. NANO PROTECH provides a 100% water extrusion rate within 10 seconds.”

Calculator Powered by a Transistor Solar Cell

 Calculator Powered by a Transistor Solar Cell

 

Who knew you could use the guts of a power transistor as a solar cell! Steven fromRimStar even takes it a step further and chains five 2n3055 in a base to collector configuration to generate enough voltage to power a small calculator. Funny how some electronics form China are working fakes. The small calculator he got has a small solar cell in it already but once the case was cracked open it turned out that the calculator was simply powered by a small coin cell battery. I wonder if the solar cell was a fake or they were just too lazy to hook it up.

“To easily make a homemade/DIY solar cell, get a power transistor like the 2N3055 and carefully cut open the case. That exposes the semiconductor material inside to light. Hook up some wires and you’re done! Doing this I managed to get around 500 millivolts and 5.5 milliamps which is 2.7 milliwatts.”

How to 3D Print an Aston Martin

3D printers are all the rage. Not sure where things will be in 10 years but I can’t wait to see what it will be like when you can pick up a 3D printer in Walmart beside the Lexmark all in 1 printer for $150. Printing door knobs and clothes pins will be second nature, just like printing a garage sale sign is today. I am not sure we will see the day when cars are printed in huge printers in peoples back garages but check out this 3D Printed Aston Martin build! Is this the future of car building? You can see the CAD file design stage here. Nice starting point as opposed to lots of the prop builders who are working from pictures but don’t let that fool you, it is a huge undertaking!

450mph Land Speed Record Project

at 11:45 pm. Filed under Insane Equipment, What Were They Thinking

 

This project will get funded at $200,000. They are hoping to get it flying across the ground at 450mph! With dual 2000 horse power engines it has tons of power to get the job done. Good luck on Danny Thompson continuing what his father Mickey Thompson started.

More Details

Streamliner Facts:

  • The skin of the car is made-up entirely of 68 hand formed aluminum panels. They are connected to the subframe via simple Dzus buttons.
  • The streamliner has two engines, one on either side of the cockpit. The original 1960s setup delivered nearly 1800hp. Our new engines provide close to 4000hp.
  • The engines are dry blocks (waterless), which means all of the cooling is provided by the fuel. A single run will consume approximately 50 gallons of nitro blend fuel.
  • The car ends its runs nearly 500 pounds lighter due to fuel consumption.
  • The tires are a prototype nylon weave backed with banded steel. There is only 1/32 of an inch of rubber. Any more would spin off due to heat and expansion. They are custom made by Mickey Thompson Tires.
  • Primary stopping power is provided by dual parachutes that deploy four foot blossoms. We also have four carbon fiber disk brakes just in case.”

Fireworks Shot at RC Plane creates some Stunning Video

at 6:56 pm. Filed under What Were They Thinking

 

Not sure how many people would shoot fireworks at their expensive RC plane but the video it creates is great. The guys from Louisiana Hog Control do this every year as part of their 4th of July festivities. Thanks to Cy Brown for sending this in.

“It has become somewhat of a family tradition to try and shoot down Uncle Cy’s expensive little toy every 4th of July and New Years.

The airframe is a Skywalker 168cm, video is over a 2.4Ghz link using Range Video equipment.  The main camera is a HoryzonHD from Foxtech FPV.  It records in HD and feeds an SD signal to the video transmitter.”

Worms with Heads Cut Off grow New Head and Remember the Past

 Worms with Heads Cut Off grow New Head and Remember the Past

 

There are lots of crazy things in nature that are unbelievable. You have probably read about starfish being able to regenerate lost arms or how frogs can freeze solid for months with no heart beat and thaw out and be good as new in the summer. Many species of worms also have the ability to regrow chopped off sections of their body including internal organs, see the video below for some information on that. It turns out that when the brain regrows it also retains the memories of the brain that was chopped off. This was tested by training flatworms to travel across a rough surface to access food prior to chopping their heads off, when the new head grew back the work remembered how to get to it’s food.

In the 50s a scientist also demonstrated that you could teach these worms to travel through a maze just by feeding untrained worms the ground up bodies of worms that were trained in the maze. Just imagine what our world would be like if the human body also operated in the same way?
