Prelude In my last post here ([Firecracker Analyzer] Creating a Wireless Sensor Node using TI's stuff.) I built up a wireless sensor node using the Anaren Air Booster Pack. They are cheap and I think I will be using these quite a lot in future projects. I wanted to use my solar harvester to power the FR5969 board but have run into issu ...
All Previous Posts http://www.element14.com/community/tags#/?tags=iot_firecracker&ICID=intheair-15grid Prelude I had initially planned to make an evergy harvester circuit around the BQ25504 which was one of the parts from Texas Instruments for this challenge. I managed to assemble one board partially since the size was so small that I managed to destroy three chips before getting one to work. Once I got it to work, I posted some information about my results. Related posts are [Firec ...
My Question to TI Does the VSTOR Pin provide output voltage in the absence of the VIN BUT in the presence of a Storage element.? NOT! Introduction I finally got around to testing the BQ25504 and it was not what I expected but I am stupid so its all good.. I assembled the required circuitry and connected my solar panel and super cap and expected the output to be reasonably 5V. Unfortunately it was not. I am going to do a flashback on what I designed and then a little on what I got. ...
Not a very complicated post just a few pics of the assembly. I use some flux and copper wire strands and used it to sweep the extra solder out... The above is the result and I check with the DMM to see if any pins were bridged. They weren't . I then moved on to solder the rest of the parts and... Viola! All I need to do is mount the coil and connect the inputs and outputs. This should be fun... ...
Setting things up
Introduction In my previous posts here and here, I made a small circuit with the prescribed parts from Texas Instruments and made a PCB for it. I recently received the passives and went on the assemble the board. This is the story of how I failed! Setting things up I started very enthusiastically and the video below is me setting up for the assembly...

Introduction The objective of this post to completely describe the creation of a wireless sensor node which can be used for IoT Applications. Texas Instruments was kind enough to sponsor the parts for this build hence the entire demo is TI BOM. Additionally, ...

PreludeThe challenge is to create a system for air quality sensing which can operate without human intervention. My idea is to create a system that can measure air quality indoors and outdoors and log this data to the Sierra Wireless System. For the indoor unit, I have a CC3200 power unit which can measure temperature and an MIC ...
Step 1: UnBox it and Get started
Step 2: Connect to our router.
Step 3: Install the Dev IDE
Step 4: Start Coding
Step 5: Understanding MQTT
Step 6: MQTT on CC3200
Step 7: Reading a Frequency and sending it via MQTT
a> Adding to main
b> Add the handellers
c> Add our task
d> Add the task to the OS
Step 8: Making things permanent
Step 9: Experiment!

Prelude I have been busy with the IoT HOliday Lights project but after its completion, I have jumped right back here. I had the boards manufactured from Seeed and they look good. I will post a progress blog separately, but right now, I need to post about my experiments with the HDC I soldered. I2C Testing with the Buspirate This mini article is part of a larger project an I will link to it at the end. For this project, I was required to use the TI HDC1000 and instead of buying a mod ...

The bus pirate.
On to the bus!
I got one of these (The LCD!) LCDs from the budget and the motive is to use them to display air quality. Low and behold I got them and these things are tiny... I mean more than I thought. BUT they should get the job done. This post is a little one where I try and get it to work and experiment with I2C. Lets go! The LCD itself To be honest the features of this LCD are great but the cost is ...
Its been a hectic couple of weeks and progress has been slow. I will be posting a series of smaller posts to cover work done and my "evil plans". One of the factors that contributed to my slow progress was sensor selection and I am still a bit stuck on that- the reasons I will explain. I also received the basic kits from E14 so thanks for the support. Lets jump in to the progress part direcly. The Sensor Problem I had planned on building a sensor system for open air and in order to ...
I had already proposed a design but it was a bit rough and after talking to some sensor vendors, I found that not only are gas sensors expensive but most of them might not be suitable for outdoor use at all. Hence I have cut down on the sensors and added expansion connectors in my design for later use. The current design is shown in the figure below. It has been a slow week due to personal reasons but I have come up with the above diagram and there are a few pieces still missing which I will ad ...
