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.”

WS2812B LED Driver Project

WS2812B LED Driver Project

 

JEELABS did a nice WS2812B LED Driver Project that uses an ARM LPC810 running at 30 MHz to get things done.

“Sending 12 bits @ 2.4 MHz takes 5 microseconds. If we were to set the LPC810 to run at its maximum 30 MHz clock, we could probably drive the SPI hardware entirely via interrupts, but for a simple timed example this is not really necessary. Instead, we can let the SysTick timer interrupt the polling loop used to drive the SPI bus – without losing track of time.”

The Useless Candle

at 1:02 pm. Filed under Funny Hacks

 

Remember the cool Usless Machine? Well now there is a Useless Candle. New idea but just as much useless fun. As soon as you light the candle the system detects that it is lit and blows it out. 🙂

“The control circuit for this project is built around a 555 timer IC. When light shines on the CdS photoresistor, the voltage at pin 2 drops below the trigger threshold. This sets the output at pin 3 HIGH and activates a power transistor. The power transistor then turns on the relay. After a short delay, the system resets itself and the output is turned off. The two capacitors are included to add a delay when turning the output on and off. The 100kohm resistor and the capacitor connected to pin 2 determine the delay in turning the output on. The fixed 10kohm resistor and the capacitor attached to pin 6 determine the delay in turning the output off. To increase either delay, you can increase the values of the resistors or the capacitors. To decrease the delays, you can decrease the values of the resistors or the capacitors. The power transistor is included so that you can activate relays that may exceed the power rating of the timer IC (200mA). The sensitivity of the sensor is set by adjusting the 10kohm variable resistor.”

Internet Controlled Robots

These Internet Controlled Robots are not available to play with all the time but if you keep an eye on the Twitter channel you will have a chance to have a look and give them a try when they are online next.

“I only put together one robot kit previously, then these two robots both started as Activity Bots.
I hooked up a Raspberry Pi with an HD camera, went through a few wifi options, and got the robot to stream video to twitch.tv and take commands from users via their chat. Later i added the Aruduino for using neopixels and some other future features. We’ve also been making dungeons around the house, made out of cardboard, making quests, and other things for people to do and explore.”

Numechron Digital Clock

 Numechron Digital Clock_1

 

built a very interesting clock called Numechron Digital Clock which is based around a very old clock. It uses an AC motor to keep time which keeps time based on the 60 Hz in the AC line.

“I really liked the Art Deco style of the Model 1364 case and chose to emulate it, although my clock is considerably larger than the prototype. While mimicking the original style, I employed considerable open space in the case design so that the clock’s internals would be visible. A Pennwood employee, F. Greenewalt, patented the mechanism for this type of clock in 1935. He developed an ingenious set of wheels, cams, and levers to flip the numerals and operate the clock. I consulted the original patent to design the mechanism for this clock.”

Power your House from an Old Washing Machine

at 3:55 am. Filed under DIY Hacks

 

Alternative energy is a hot topic. If you are looking to lessen your reliance on the grid you might want to look into a windmill or watermill. In this video Buddhanz shows us how a used Washing Machine can be turned into a power generator. Looks to be a cool weekend project. Most people would need to opt for the the windmill version but the water powered type is very interesting also.
