This blog will focus on establishing the wireless link between the glasses and the base unit.In order to not make it too long, I've decided to split into two parts: The server part and the client part. This post will describe the server part.&nbs...
This is another example of the Audio Circuit for my Hearing Guard System using the MSP-EXP432P401RMSP-EXP432P401R with the 430BOOST-SHARP96430BOOST-SHARP96 LCD showing the audio input I'm using TI Energia MT for MSP432 to prototype the di...
Hello everyone, this post is about carbon fiber tape and how it will be used. The carbon fiber tape has arrived!! This update is showing how well the carbon fiber works as a heating element. Below are pictures of the carbon fiber. In them you ca...
Hello guys, I'll be receiving the kits in a day or two, so excited about it, this weeks write-up is a short video describing our game plan. What we have actually planned to do. We actually made a small change, We replaced the Rpi with I...
This update covers my first attempt to fire up the MSP-EXP432P401RMSP-EXP432P401R I am using Energia at this point since they claim to support this platform and the Sharp display.I modified the 430BOOST-SHARP96430BOOST-SHARP96 to be alway...
Getting started with TI RTOS and CC1310
What is an RTOS
The CC1310 sub GHz launchpad
Getting back to TI RTOS
What is POSIX
What next?
Getting started with TI RTOS and CC1310 The CC1310 is a sub Ghz single chip solution that run...
I received a box from element14 today - so here is the unboxing video....lots of great modules.....players.brightcove.net/.../index.htmlMy next blog should be on RF radiation, but I also want to power up the MCU module, so we will see what is ready f...
Hearing Guard System - Noise One of the main requirements of the Hearing Guard system is to be able to detect noise levels at pre-selected thresholds. This will be performed by the use of an audio input circuit as well as software to provi...
The next topic in this series on invisible hazardous substances is radioactive materials.We don't usually think of ourselves as being in danger from radioactive particle radiation, but we are all exposed to radon every day.What is Radon, why is Radon...
Hi everyone!! Today there was a delightful surprise waiting for me when I got home!! The Safe and Sound Texas Instruments kit arrived. Attached are pictures of the opening and everything that arrived. Waiting to be opened!!  ...
My safety helmet design can be divided into three categories. The first category is data acquisition from sensors and processing them to predict the potential explosion. The second is tracking the miners and determine their current or immediately pre...
Short recap of introduction blogThe idea: Power tool safety glasses that will not allow the tool to be switched on unless the operator is actually wearing them.The problem: What type of sensing should be used by the glasses to achieve a reliable read...
This blog details the circuitry and PCB layout of my custom Booster Pack to monitor 8 hazardous gasses and ultraviolet light. I added some active circuitry to filter the CO2 sensor PWM output since my last blog. This is a 4-pole low-pass Butterworth ...
Hello guys, hope you all are doing good. Seems there is some delay in shipping the kits,so I was wonder what to post for the blog, I thought of posting the Video streaming and Cloud part, but i'll be too vague without the T-*** part,so decided to wr...
How to make an MSP432 LaunchPad talk i2c to a DAC.This TI-RTOS program tells the DAC to output a sine wave. It could be something else but I reused an existing Arduino sketch. In my previous i2c example, the focus was on reading data from a sens...
So with the hardware delayed and my office space being reduced to a small box, I am working with a number of things. I installed the Code Composer Studio Software and it turns out I have some Anaren CC110L Booster packs in my inventory. So I decided ...
In an attempt to keep this project organized and on track, I am going to implement some Agile Methodologies where it makes sense. My first attempt it to create User and Technical Stories for the Requirements that I have at this time. The reason...
This blog discusses air quality and how it can be monitored, especially odorless and colorless gasses like carbon monoxide and carbon dioxide. Air QualityThe list of common items that off-gas nasty chemicals into the air is depressingly long and...
In this posting I will show how the heating will work. I haven't received the Carbon Fiber (It has been shipped from Russia) so this will be my backup. I have taken apart a 12v heated seat cushion for the element wire. Below are photos of ho...
Hello everyone! Welcome to my (late) introduction blog. I'm very excited to be a part of this challenge and wish good luck to all participants! Why safety glasses? According to Prevent Blindness America, more than 700,000 Americans inju...
Hazardous environmental factors are really not anyone's idea of a fun topic, so I want to keep all the gory depressing medical details to a minimum and focus more on the technical challenges of monitoring and measuring these invisible quantities. The...
This week I decided to take time to sort out some of the software resources that I will need to complete my project. The main one was deciding whether or to use Code Composer Studio v7 or v6 as well as MSPWare v2.x or 3.x. I plan to use a BOOST...
