GIANT Flip-Dot Display

at 7:54 am. Filed under Insane Equipment

 

Check out this GIANT Flip-Dot Display that is certainly not coming to a store near you. The ooVoo isn’t selling displays, rather they wanted something in their booth to set them apart from the other high pixel count displays. Sometimes going mono color and low res pays off! The resolution is only 588×126 but when you consider that these are 74,088 mechanical pixels that make up the display that is pretty amazing.

“Each module has a built-in controller which are commanded via serial. To gang 189 of them into a single display, [Pat] sourced some serial to Ethernet hardware from Grid Connect. These adapters report back to a single computer via 64 Ethernet cables. That box plays back a video file, adapting it on the fly using Adobe Air to send packets to the IP addresses of the Ethernet controllers.

All of this is supplied by a trio of 56A, 24V power supplies. At a refresh rate of 30fps, when flipping all the dots at once this is a max current draw of 189 panels * 0.680 Amps = 128.52A @ 24VDC (Same power as 28 Amps @ 110VAC = 3085W).”

Beer Pong Robot

at 6:36 pm. Filed under Insane Equipment

 

When you have a look at this Beer Pong Robot video by Empire Robotics you can see that some cool engineering went into making this robot very accurate (or a ton of takes were taken). The green thing on the end of the arm is what Empire makes, it is an ingenious mechanism for gripping items.

“The core principle behind VERSABALL is the jamming phase transition of granular materials. The green ball is filled with a sand like material. When air is pumped into the ball, the ball softens. The ball is then pushed against the target object. Pulling air out of the ball jams the sand like material together, causing the ball to harden. This transition from soft to hard creates the gripping forces.”

ABB Robotic Barista

at 4:51 pm. Filed under Insane Equipment

 

We have seen how impressive the ABB Robotic systems are, have a look at the latest example. Here we have a ABB Robotic Barista from Automatica 2014 Munich. The robot opens the coffee brewer, selects and inserts the coffee grounds container, positions the coffee cup, places a plate and puts the coffee cup on the plate. Finally a conveyor brings the coffee out of the protective robot enclosure to the customer. What a great demonstration.

Double Prosthetic Arm with Mind Control

Double Prosthetic Arm with Mind Control

 

What a great job the team at Johns Hopkins University Applied Physics Laboratory did. They built this Double Prosthetic Arm with Mind Control to allow Les Baugh to once again have arms and hands. He lost them in an electrical accident over 0 years ago. I can’t imagine the feeling Les has after so many years living without arms and now finally have some high tech versions to work with. They are controlled using nerve signals so Les will learn to control them with his mind. Surely this will be a challenging task but the reward is outstanding!

”We use pattern recognition algorithms to identify individual muscles that are contracting, how well they communicate with each other, and their amplitude and frequency,” Chi explained. “We take that information and translate that into actual movements within a prosthetic.”

Then Baugh was fitted for a custom socket for his torso and shoulders that supports the prosthetic limbs and also makes the neurological connections with the reinnervated nerves. While the socket got its finishing touches, the team had him work with the limb system through a Virtual Integration Environment (VIE), a virtual-reality version of the MPL.”

MagneBike - Magnetic Wheeled Robot

 

The MagneBike is an interesting magnetic robot that is surprisingly flexible and can maneuver some crazy metal geometries.

“Locomotion Concept and Robot Design

  • Two wheels in a motorbike arrangement: better adaptation to the surface (flat or curved).
  • Magnetic wheel unit including lateral lifter/stabilizer arms. The lifter functionality helps to pass over step obstacles. The stabilizer functionality allows to drive sideway.
  • Five active DoF: front/rear wheel, front/rear lifter, steering unit.”

Electron Microscope Image Capture with an Oscilloscope

at 2:06 pm. Filed under Computer Hacks, Insane Equipment

 

What to do after you get your hands on a discarded scanning electron microscope. Ben Krasnow from Applied Science took the signal directly out of the device and fed it into a DSO. He was then able to capture it at a much higher resolution than is displayed on the original CRT that came with the unit. The results are incredible.
