We are surrounded by data

November | 2011 | Sensors Everywhere
https://sensorseverywhere.wordpress.com/2011/11
We are surrounded by data. Archive November, 2011. We want to process the electromagnetic field (EMF) data in real time to determine if it’s 60 Hz or maybe in another frequency range. Wow, having different colors to indicate the type of EMF around an appliance, that would be very interesting! But before getting carried away, there is some number crunching to do. Goertzel algorithm from mstarlabs. Still a lot of number crunching. Would a result every two seconds be too slow for us? Robot, Feed Thyself.
Battereyes are watching you | Sensors Everywhere
https://sensorseverywhere.wordpress.com/2011/12/19/battereyes-are-watching-you
We are surrounded by data. Battereyes are watching you. Even a battery can be a sensor. I measured the current in a remote control battery while pressing various buttons. The typical remote control dumps a LOT of current through an infrared LED (up to 1A momentarily). The better to reach a TV or DVD player in a far corner of the room. This activity shows up clearly in the battery current. Whose sensor kit will be available in January) and Twine. Battery current when remote control button 5 pressed. For g...
Visualizing 2.4 GHz with long exposure photography | Sensors Everywhere
https://sensorseverywhere.wordpress.com/2011/12/14/visualizing-2-4-ghz-waves-using-leds-and-long-exposure-photography
We are surrounded by data. Visualizing 2.4 GHz with long exposure photography. Here’s a nice visualization from Greg Charvat at MIT using a LED-equipped sensor to map out 2.4 GHz waves. The sensor detects the direction as well as magnitude, so you get two different colors. The 2.4 GHz frequency is used for Bluetooth, wireless sensors (especially ZigBee), Wi-Fi and almost every other gadget. If you’re in the US. 60 Hz EMF filter implemented on Arduino.

60 Hz EMF filter implemented on Arduino | Sensors Everywhere
https://sensorseverywhere.wordpress.com/2011/12/11/60-hz-emf-filter-implemented-on-arduino
We are surrounded by data. 60 Hz EMF filter implemented on Arduino. Raw and filtered 60 Hz signal sampled at 500 Hz and sent over serial link. It’s very sensitive to whether the antenna is being touched–higher values are when it is touched, then it drops off when not touched as shown about halfway through the graph. But if the user is also touching ground while touching the antenna, the values drop to nearly zero. Int inPin = 5; / analog 5. Volatile int val; / where to store info from analog 5. Long late...
60 Hz digital Arduino filter does the job! | Sensors Everywhere
https://sensorseverywhere.wordpress.com/2012/01/10/60-hz-filter-works
We are surrounded by data. 60 Hz digital Arduino filter does the job! 60 Hz filter performance measured using function generator. To test the digital filter, I removed the EMF sensing resistor and antenna, and then plugged in a 1V peak-to-peak signal from a sine wave generator at different frequencies, up to the maximum frequency of 250 Hz (half the 500 Hz sampling frequency). It gets a little bumpy at low frequency, probably because we’re averaging over a small number of cycles (less than 3). Long lates...

At the University of Louisville J. B. Speed School of Engineering. PhD Fellowship Contact Info. Pop up 3D structures printed on stretched fabric. Posted by cindy.harnett@louisville.edu. July 6, 2015. But why would you want to do this? Since 3D printing time scales with volume, it can be much faster to produce a pop-up structure from a thin sheet than to 3D print it directly. Their brains are still made from brittle silicon-based computer chips. Fabrics have diverse properties: they’re flexible and ...
