Arduino control using a Google Glass

As a fun test of glass gdk development alongside communication with an arduino webserver I wrote a small glass app that communicates with a previous project. The previous project consists of an arduino webstation that tracks temperature and humidity and provided the data on it's webserver. This was back in Pittsburgh, where it was pretty cold, and I thought it'd be fun to be able to tell the measured temperature outside handsfree.

Usage: Say Hello Home via google glass and you can communicate with an arduino webserver, asking for the temperature or turning on/off the lights (a little LED in this case).
Question
Calling up the app using a voice command
Say Okay Glass, hello home and then you can say:
  • Any variation of what's the temperature? - It will display the indoor and outdoor temperatures in the apartment
  • Any variation of turn the lights on - It will enable a switch (in this case turning on the LED)
  • Any variation of turn the lights off - It will disable a switch (in this case turning on the LED)

The arduino webserver consists of an arduino with an ethernet shield, connected to a DHT11 temperature/humidity sensor and a barometer sensor.

Visualizing TLE Orbital Elements with Python and matplotlib

Image
A Two-Line Element Set (TLE) is a way of encoding orbital elements of Earth-orbiting objects at a given time. This is the format NORAD provides data on many satellites in space right now. It'd be nice to see that as a 3d visualization. We use python to parse text files pulled from NORAD, and plot with matplotlib . Military satellite orbits For example the TLE for SpaceX's Dragon spacecraft during the CRS-2 mission was dragon = """DRAGON CRS-2 1 39115U 13010A 13062.62492353 .00008823 00000-0 14845-3 0 188 2 39115 51.6441 272.5899 0012056 334.2535 68.5574 15.52501943 306""" orbit.py  contains the code to parse the TLE into components as well as call graphics to draw it. print "Satellite Name = %s " % title print "Satellite number = %g ( %s )" % (satellite_number, "Unclassified" if classification =

Strawberry DNA extraction and viewing with a cheap USB Microscope

Image
I had recently bought a cheap USB microscope  (10/60/200x magnification) and thought a fun use for it was to try and see DNA! DNA is really small though, so we can't expect to see the components of it with a cheap microscope, however it is very long, and it turns out strawberry DNA is the easiest to see and extract. Microscope with DNA on a slide I followed this DNA extraction lab by Steve Spangler , which was very easy and fun to understand. I took an album of videos and photos during the process. We can clearly see strands  10x Magnification - DNA strands clearly visible within slide As we zoom in further, we can see the clumps of DNA strands start to show up. 60x Magnification - we can see some foreign debris in the slide, the strands look like spiderwebs. One thing to note, the microscope puts out color images and default camera settings, which with a backlight makes it pretty hard to see anything. I added a light source to the side as well as pushed

Relearning web development by writing a clicking game using React, Npm and Browserify

Image
I had some free time this vacation, and came across this interesting little sandbox game called  Pokemon or BigData by pixelastic . The aesthetics of the code are clean and simple. It uses React , which seems to be used for real-time web UIs. It also uses  npm  as a package manager. My previous forays into async calls in web dev were not nearly as pretty, so this seems like a good opportunity to learn something new. I decided a fun first start would be a simple game, and the simplest game I could think of was clicking a button to make a count go up. To give it some real-time feedback, I added some upgrade buttons that automatically click for you, a common incremental game technique. The buttons don't show up until there are enough clicks, and are grayed out if there's not enough to further upgrade. I set it to run at 50Hz to feel responsive. The heart of the code is basically a state machine that contains the current number of clicks and the number of upgrades
