Hello everyone,   I have received the runner-up prize and I am so excited!! I can't wait to get out and give it a try. Below are pictures of my new toy.   I want to thank everyone involved with the Safe and Sound design challenge especially our great sponsors!!   Dale Winhold   p.s. I will upload video of the first flight ...
Safe and Sound – Winter Survival Suit Summary – Blog #14 (Final post)   This has been a great challenge that I have enjoyed immensely.  Since the start to completion there have been many challenges and accomplishments. I have to say the biggest challenge was getting the temperature sensors to work and the biggest accomplishment was water proofing the electronics. The idea of the suit has been on my mind for years, basically every time I went outside in winter time. I alwa ...
So where did we leave off, oh yes, finish up the survival suit. In the past week I got a lot accomplished, below is my "to do" list of things to complete from Blog #11. The list has gotten short, the project is almost complete, so little left. Here is my update:     Things to complete: (Blog #11) So, what is left to do? Here is my list: Solder the sensors to the leads Attach everything to the suit Add in the carbon fiber power quick disconnects Heater manual over ride Case for c ...
Hi Everyone,   This will be a short update on how things are coming along. In the past week I have been fighting a bad flu bug so I didn't get as far as I thought.   So, I have been wiring the power that goes to the heat elements complete with disconnects. Where the power runs into the 8 switch relay is where I put in the by pass switches. Now there is the ability for the user to heat the suit in case of computer malfunction. Due to the importance of this suit we can't rely 100% on t ...
In this post, I will show how everything is coming together and works. After a frustrating 2 ½ weeks with my code not working with the temperature sensors I got that issue solved. I did post the solution but here it is again. There was an error with Energia compiling the code for the MSP432 Red. Before I knew this, an error showed up while compiling saying “analogRead” was not declared. This was odd but I declared it in my code and everything compiled but wouldn’t read the ...
I'm not sure how much of an update this is considered. I am having issues with the temperature sensors (DS18B20 Temperature Sensors) which are OneWire. Now the issue is that they don't work on the MSP432P401R. I have tried everything in the past 2 weeks and a lot of different coding to no avail. I copied and pasted code and even used the code in Energia for the OneWire temperature sensors and nothing worked. I found some information on line saying all the coding for the sensor works on the MSP43 ...
This update is about water proofing my project. Everything done here is the first time I ever worked with this product and it was done live, so if it fails we will all see it go wrong. There are 3 videos attached, the first is showing the product, second is applying it to the board and third is putting the powered board under running water.   I use an Arduino Uno as a test so if this doesn't work I don't wreck the MSP432.   So, what do you think? Will it work? Fail? Here is the chall ...
This week’s update is about the temperature sensors and dealing with the possibility of moisture issues.   First is the temperature sensors:   I finally received the temperature sensors yesterday!! I have been working most of today with Energia to get them working. At the time of writing this blog I am still working on the script. I will post an update blog when it’s up and running. The sensors are the DS18B20 Temperature Sensors. OneWire requires a single 4.7K pullup r ...
Safe and Sound Post#7 (Let there be power)   Unfortunately I still haven't received my temperature sensors, so I am unable to fully assemble the suit. I have the carbon fiber sewn into the suit and ready to be tested. This past week I have wired the computer to the power switch and ran all the wires required to power the suit. I used alligator clips to connect the wires to the carbon fiber, this will also act as a quick connect/disconnect. It will also act as a safety if something should g ...
For this weeks update I will be discussing the power requirements to heat the suit. I have finished sewing in the carbon fiber heating tape into the suit. I used 750mm lengths of tape to keep my power consumption consistent (It also worked out that way). For each leg I used 2 lengths, for the arms I used 1 length each and for the torso I used 4 lengths. If I would have thought this out when I ordered the carbon fiber I would have ordered more, I bought just enough for my suit but the wife and ki ...
Safe and Sound – Winter Survival Suit Post 5   Here is where I am at so far. I am waiting for my temperature sensors to arrive (Taking a lot longer then expected). I do have everything else required to complete the project. For the past week, I have been working on sewing the carbon fiber into the suit as well as programming the  MSP-EXP432P401R to regulate the suits temperature I will be using an 8 Relay Module to control the power going to the carbon fiber   For those o ...
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 can see that it is like fabric, it feels like silk. I am using 18650 3.7v 2600mAH batteries, I have purchased 8 of them hoping that will be enough for the entire suit to operate; they are rechargeable!!   Here is some interesting fact about c ...
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!!     Look what is inside...     Out of the box, really nice!! Thank you Texas Instruments & Element14. Now the fun begins             The main part of the project!!     ...
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 how I set it up and used 4 C-cell batteries to supply the power (C-cell batteries are bulky so they won't be used in the suit. I used 12 feet of heating element (A lot longer then what I will be using in the suit). From the start temperature to full tem ...
Safe and Sound – Cold Weather Survival Suit Post #1   Reason why: This is a news report from January 11th, 2017:   On Tuesday, the warnings covered northeastern Alberta, almost all of Saskatchewan and much of western Manitoba. All people in those regions are being warned of extreme conditions into Wednesday morning that feel like -45 to -52 with the wind.   Attached is another Alberta winter weather report from 2 weeks ago.     As you can see, we get sever ...
