An Answer To My Past From My Future

An Answer To My Past From My Future

This is an email that I had written to Parallax when I was trying to redirect readings from a WattsUp Meter to a data logger.  I had just started out with basic stamp programing a year before this.  It’s suppose to be humor, but it sure would be helpful if this actually could work, especially come Lotto day!

Bluetooth – Taking a bite at phone and micro control links

Bluetooth – Taking a bite at phone and micro control links

The most direct route between a smart phone and the micro controller world of sensor appears to be bluetooth.  This wireless technology has been around for some time now.  The hard work has been done and the road has been laid out. Control your Arduino board from your Android device over Bluetooth, here’s a demo.  How easy is that! The adapters are simple and inexpensive.  The smart phones have bluetooth support.  It just makes sense.  I was able to find…

GSM, Iridium, and other wireless communication options.

GSM, Iridium, and other wireless communication options.

The connections subject spanned at least 8 percent of the entire material covered.  Most of it pertained to wired connections and physical connector types.  There was little mention of wireless options.  Those that were included RF, Sound, and Light.  None of these were demonstrated with code or some working example. Since the next quarter will involve cloud data processing, this data will need to be uploaded wirelessly.  This will introduce new methods like WiFi and GSM.  I would like to…

The Internet Of Things

The Internet Of Things

The next quarter I’ll be covering 4 P’s, these are Processing, Pi, Phones, and Presentation. Processing is an application that will do some interesting tasks.  The development platform is similar to Arduino and was first demonstrated to me from Jeremy Blum’s tutorial blog.  I’ve seen it used in other uses and find it useful to know for future projects. Pi is a reference to the Raspberry Pi platform.  This extremely small and powerful computer is being used in ways I…

The End of Winter Quarter 2014

The End of Winter Quarter 2014

The subject mater covered this quarter was done in a strange and different way than I had traditionally.  The daily blog entries and micro projects didn’t give me the same sense of purpose that term papers had in the past.  The scattered nature of the material made me aware that the blog entries were key in gathering it together.  It was by this that my sense of purpose and accomplishment became clear.  Unlike the term papers, the blog still has…

Silly or Serious?

Silly or Serious?

This last post for the quarter started out with me looking for someone that put it all together.  Turns out I found this instead and it got my attention. Measuring Pollution and Health – Wearable Project Wins Prize.  It was dated July 11th, 2013.  What was the prize?  A sum of $15,000.  Here’s one of the winners with a project demo. I’ve seen some impressive work done by folks and to think this sort of work doesn’t have rewards is…

Arduino Geiger Logger

Arduino Geiger Logger

This idea came late in the design phase of the sensor helmet.  As it turns out, commercial sensors for detecting radiation aren’t as tiny as sensors for detecting light, sound, motion, etc.  Also, they are 10 times the cost of other conventional sensors.  The cost and size would prohibit the sensor being integrated with the sensor helmet, but it could still be used for specific mapping purposes. I was able to initially source detectors online from resellers like Sparkfun and…

Dust In The Wind

Dust In The Wind

The 3 GP2Y1010AU0F Compact Optical Dust Sensors arrived in the mail the other day.  These are air quality sensors that use IR to detect fine particles and smoke in the air.  I’ll be using them with my sensor helmet to detect air pollution and plot the results on a map or overlay the readings on my action camera video.  They are smaller than I envisioned.                 Sparkfun sells them but they were out of…

Smart Helmet Connectors

Smart Helmet Connectors

The method of interconnecting the sensors, micro controller, cameras, data storage, and power together will be simplified for a couple of reasons. I will need to be able to move sound sensors around during testing. Also, I’ll need to be able to install all of the devices easily once I’m ready to finalize the helmet.             The BLS female housing are perfect for this purpose.  First, they are small and compact.  This makes it easier…

Capturing Display Data

Capturing Display Data

What would (fill in name here) do!? This has been a lingering problem I’ve been chipping away at for the past 4 years.  It’s the reason I choose to restudy electronics.  It all started when I purchased a watt meter for my ebike setup.  It displayed information about my battery voltage level, watts used, and amp hours used. The watt meter has large guage pigtails to patch into the power source and load.  The problem was these wires were too…
