Bluetooth protocolEverytime I search something in the opensource community, a quote from Isaac Newton comes into my mind "We are dwarfs on the shoulders of giants" It's unbelievable the health of information is available for you to give for...
Memory retentionAirMobile sensor is going to be switched off abruptly whenever the Peltier cell does not provide enough energy. I need to save application status to resume execution properly after a "black-out" The MSP430FR MCUs features an internal ...
This week I have been mostly busy around the design of the flow of data in the system. Working from the high-level architecture presented from this post, the diagram below presents how data flows within the different component of the system.Fro...
The AirMobile caseWhile struggling to find a cheap 3D printing service to print the sensor case, (this challenge is actually costing me more than I planned!), I saw just in front of me a nice case from Wurth Elektronik I noted down t...
Hi everyone!! This is Chrystal writing this post on our progress. Sorry about the delay in getting the update posted, the holidays distracted us a bit, but now that Christmas is over and everything has slowed down (except school) we have got a f...
Representing data on the mapIn this post I will talk about the representation of data collected by AirMobile on a map. Representing data o the map is the easiest way to understand the locations to avoid when doing outdoor activities. The solution I w...
Low-power delayThe CCS ULP Advisor tool is a great tool because it provides useful hints to squeeze microampers out of an application.One of the suggestions was to get rid of delay loops. So I investigated how to implement a delay using timers. Imple...
There are a lot of resources available online to setup the Beagle Bone Black and connect it with AirVantage. This post will be a quick start guide to get your BBB talk to AirVantage in under an hour (assuming all things going well). A Bit ...
RAM ExecutionWhile building the AirMobile application, a noticed some warnings from the ULP Advisor tool. In particular, the warning was about floating point operations, which are said to be processor intensive and consume many instruction cycles, wh...
Bluetooth moduleThe AirMobile sensor will communicate with the smartphone using a Bluetooth module. The obvious choice for an application that harvest energy from wasted heat should be to use a module that supports Bluetooth LE technology. However, b...
Merry Christmas everyone! We're all busy during this festive weeks and it could never be better as I've received my proto boards on Christmas eve. This is all for now, and will be posting more updates as the boards get populated an...
Update:Waiting for parts and working with the Launchpad CC3200. No major progress. Merry Christmas (see Figure 1). I modified the year in the picture. Figure 1: Closed for Christmas (Source: Holiday Closure | Fowler Museum at UCLA)
Sending sensor readings to airvantage : For this i connected airvantage to the beaglebone black and after its connected go to http://192.168.7.2:3000/This is the cloud9 workspace.Now in the cloud9 workspace go to terminal and in the defaul...
Setting up Airvantage In this post i am going to connect beaglebone black to airvantage. For this connect beaglebone to the pc and update it. Then following the steps below i was able to connect it to airvantage and update readings a...
So many sensors, so little time!Have been studying sensor datasheets all this time to make up my mind on what sensors to use. Found it very hard come up with a meaningful, doable and useful selection. I was tempted to go for a full blown list of thes...
Sorry for the delay in updates. Been sick with the flu and only just on the mend. A week behind schedule here so I'll be playing catch up. Here are the parts that I will be ordering today through Newark: Designator Newark Order CodeManufacturer ...
