Vinyl LP under an Electron Microscope

at 9:53 am. Filed under Complex Hacks, Insane Equipment

 

Have a look at the great video of this Vinyl LP under an Electron Microscope. Using an Electron Microscope isn’t as easy to use as a normal microscope, in this case the vinyl needed to be metal coated to be viewed. The scanned data was captured with a DSO and processed into a short video. It looks amazing, I didn’t realize how Vinyl Records LPs encoded the 2 stereo channels. The CD also looks very interesting up close.

Virtual Mouse

at 7:43 pm. Filed under Complex Hacks

 

This Virtual Mouse project by r5rejeet shows us how OpenCV can be used to interface the camera image and process it into a HMI device. You can move the mouse pointer around the screen by moving your open hand around, you can click by simply closing your hand. This allow for a surprisingly good looking gesture interface.

Google’s Project Wing Delivery Drone Prototype

at 11:29 am. Filed under Complex Hacks, Cool Gadgets, Insane Equipment

 

Can’t wait till this style of delivery method is available. Tested had a first hand look at the Google Project Wing Delivery Drone Prototype. Not that it will have a direct replacement for things such as pizza delivery since the payload needs to currently be quite small but the flight and delivery method is great. Scaling these up to handle larger packages would make it great for package delivery directly into your secure back yard in minutes. I guess the only concern people will have is what happens when something goes wrong and it falls from the sky and knocks someone in the head.

Gesture Control iphone Dock

 Gesture Control iphone Dock

 

Zhiyuan Teo and Mohit Yogesh Modi made this iPhone Gesture Control for their ECE 5760 Final Project. Their system uses a camera to look for certain gestures to control the docked iPhone.  The current version uses a green square as the item that is being tracked and there are 4 video regions that are being watched. With a bit more work a hand could be tracked instead of the marker cap.

“A video camera captures gestures that are then translated into commands to be issued to the iPod/iPhone (which for simplicity we will subsequently refer to generically as ‘iPhone’). For our project, we used the Altera DE2 FPGA board to process the video and communicate with the iPhone. There are three principal components in our design: an iPhone controller module, a VGA controller and a camera input system. The iPhone controller is responsible for the I/O with the iPhone via a TTL serial interface. The VGA controller outputs a video containing a composite of the input camera image, iPhone metadata and gesture tracking information. “

Shrink Paper Money

at 11:51 pm. Filed under Complex Hacks

 

We have seen methods of shrinking coins before. In the video above Ben Krasnow shows us how to shrink paper money using liquid anhydrous ammonia. Ben dips the money into the ammonia, lets it dry and repeats the process. Each time this process is repeated the bill shrinks slightly. Sure makes for an interesting looking bill but be prepared to have a conversation piece that you won’t be able to spend.
