I cap up my participation in this design challenge by this final blog, which is basically a summary blog. I have written 12 blogs in total for this design challenge including this blog.
Theme
I had proposed to address two problems as per the theme : Save e-waste, Reuse, Repair, Recycle. I have used junk materials as can be seen(old, some had rusted connections), scrap servo motor, a scrap 4-wire motor, which only lacks filter to
I have designed an applet, which allows company owner to monitor see, Senior management can be allowed to see with username and login.
I have attempted to take the oximeter and ECG to medical grade, for which I will shortly submit my research papers to clinical experts along with my Novel ß-Bio Unified Theory/ß-Bio Propositions/ß- Bio Models
Problem 1 : Scrap Metal
Addressing Way : Solar based Power Supply
Problem 2 : Health CheckUp of Engineers/Technicians/Workers in this Recycle Enviroment
Addressing Way : Air Purifier, Oximeter and ECG
My Participation in this design challenge became a story!
Firstly, I proposed a recycling of scrap metals by a powersupply based on solar energy, which could not be designed in the time duration mentioned, then when got selected and started doing calculations, found the chosen Mikroe cannot help me in achieving that goal. So, I posted comment on the main page of this design challenge "Very Urgent", and also sent messages to Phil (e14phil) and Sean Rutledge, so they do not ship me the kit, and requested cancellation of my selection, or change the board with some other board.
Then, it even came to that the Phil, wrote me of removing my name from this contest as an official challenger and it was 13 Dec., when the contest buildup got started a month ago on 15 Nov. This, I had even mentioned in the forum 'Project Dates/Deadlines' but no clearance was given whether I m in this design challenge or not.
Then on 5th Jan, I got an email from UPS, that some parcel would be delivered on 6th Jan but didnt received and the shipping status was " labelled and delay(on the way" which looked like it was still in USA even on 13 Jan. Then again I wrote to Sean Rutledge, asking about the parcel and its contents whether IoT or somethng else.
Then, on 19th January, Sean said, parcel is moving now and wait. Then on 22 Jan., I received.
And, then on 23rd or 25th, Phil announced Official Deadline Extension - 2 Week Notice
Thanks to my earlier effort and also the ongoing work (which I was doing for personal R&D) even during the hung decision whether I would be the official challenger in this design challenge or not.
I have used e14 Equation Editor, to write equations with subscripts.
Note to Judges
Judges can see, I have stick to the theme of the challenge - recycle, IoT, scrap, monitoring, health care.
I do not know but even If I come in Top 2, the prizes are not usable to me as here in Delhi, India, AC Voltage is 230 VAC, 50 Hz, whereas the prizes have AC power of 110 VAC, 60Hz. So, in case Judges find my entry in top 2, pls replace it by other, except solar panel which can be used universally.
If my submission do not make it to top 2, no problem.
Blog 1
Blog 1 : Introduction- Recycle Metal & Taking Care of Employees Health in ReCycle Environment
In this blog, I have done unboxing and the introduction and described the two problems which I would like to address in my proposal application. I also mentioned story of how one click board got changed by other and I had requested for its cancellation of participation and/or change of the board.
Blog 2
Blog #2 : Understanding Architecture of Cortex M4F and SAM E51
In this blog, I dived into detail, architectures of RISC ARM Cortex M4F Architecture, ARMv7E-M architecture and 32-bit Microchip's ATSAME51J20A.
Blog 3
Blog #3 : Understanding Architecture of RTOS
In this blog, I dived into RTOS and SysTick; and why HardRTOS is needed for ICU and in modern vehicles.
Blog 4
Blog #4 : Understanding Microchip Curiosity Nano Kits and Set up
In this blog, I explained and explored in detail - Microchip Curiosity Nano Base Evaluation Kit, Microchip SAM E51 Curiosity Nano Evaluation Kit and did software set up.
Blog 5
Blog #5 : Taking Mikroe ECG Click from Prototyping to Medical Grade ECG Click
In this blog, I explained Mikroe Click boards ECG Click and mentioned manufactuer's disclaimer - It is a prototyping tool, not a medical grade device. Do not use it to diagnose patients.
I have also explained how I will take it from Prototyping to Medical Grade ECG Click.
Blog 6
Blog #6 : Moving Towards Clinical Grade Oximeter & Respiratory Diagnostics
This blog is basically all related to Air purification, air movement control and how it will be done.
I have explained Mikroe Click board - Oximeter 2 Click and mentioned manufactuer's disclaimer - It is a prototyping tool, not a medical grade device. Do not use it to diagnose patients.
I have explained four scrap motors, a scrap buzzer, a scrap accelerometer and a pressure sensor would be used.
I have also explained how I will take it from Prototyping to Clinical grade or ICU grade.
Blog 7
Blog #7 : Securing Recycling Factory Database and Medical IoT Cryptography
In this blog, I have tried to implement cryptography and showed a demo of a single user using SHA-256. I have also given 'self-test' code from datasheet. The codes are elementary and taught in so-called engg colleges, and once told to 17 yr or 20 yr, see intelligent, see iqx ; if not, its phd level. As far as coding is concerned, critics/hypocrites (might be universal) know it is available on the internet and just interfacing.

Very Important Feedback to Sponsor Microchip
Pls forward this to Microchip or if Microchip's Engineer's are reading
Firstly, I thank Microchip for being the sponsor and selecting me as an official challenger (along with e14 Judges and staff)
The board, PCB, the silkscreen, solder masks, PCB layout, labeling are all excellent and I appreciate the engineer who has made it but there are 2 extremely important corrections need to be done on Curiosity boards
1) On Curiosity Nano base, like I have placed LCD MiniClick on 'Click 2", as this LCD can work on 3.3 or 5VD. But when I give both 3.3 V and 5VDC power supllies to 'Curiosity Nano base', the power supply wire starts melting and burning.
If I remove one power supply like 5VDC, it works OK, and you can see despite 3 times or 4 times burning of the wire,the board and components are fine, and its rocking.
So, either switch selector or a small circuit can be incorporated in 'Curiosity Nano base', as connecting both 5V and 3.3 V power supplies and batteries to 'Curiosity Nano Base' causes burning and melting of wires.
2) There are three minor errors on silkscreen for pins PB10, PB5, PA5 on the PCB of 'SAM E51 Curiosity Nano'
Thanks Note and Suggestion
Lastly, I thank Organizers, Element14, Staff who has organized design challenge without restrictions on qualification, age, marks, country, only school or college, or only from recognised ... , mandatory professor, blog word limit or other kind limits on blog writing etc, a trend which they must continue because there are many and the level of performance cannot be same and shouldn't be expected. Because all do not get the chance. But there is fallout from selected contestants and better outcome can be obtained.
E14 may further incorporate lengthy design challenges or some compensatory (those who need, not on hire but as business or proper business), as there are design failures, personal problems ; these challenges may can extend to have 4-6 months, which will allow to develop prototypes properly. Definately one can do such lengthy projects in personal R&D without in connection with any design challenge because proper complex or industrial type project can take 1 yr or 2 yr. There would be some who wont like to go for lengthy design challenges, And even I m not certain of myself whether I will like to go or can go that time or not.
