Blog 1 : Introduction- Recycle Metal & Taking Care of Employees Health in ReCycle Environment

Hello Everyone

This is my 4th design challenge with e14. Thanks for choosing me among 15 challengers as an official challenger in this design challenge 'Upcycle IoT Design Challenge'.

The main theme of this design challenge is : Save e-waste, Reuse, Repair, Recycle.

In my submitted proposal, I had submitted following  2 problems.

Problem 1 : Scrap Metal

Addressing Way : Solar based Power Supply

The thin border strips from LCD laptop computer screens are of aluminium, the connector plug pins are of metal, aluminium wires (not insulation), batteries connecting ends are of metal. So, I want to address problem of scrap metals from PCB, computer, LCD screen, plugs and other metal scraps into useful.

My proposed addressing way is to melt metal from these scraps using electricity and turn this waste into something beneficial to humanity from Solar based Power Supply to melt metal.

But to melt such metals in kilos/tonnes and converting to useful shapes needs many other costly items. As this is a home based developed, my objective is not to develop such hug setup requiring apparatus. So, the development on this scale wont be addressed and wont be developed.

Such melting of wires using electricity generated from solar panel, not from mains grid, and later turing into another shape, will reduce and recycle scrap and the metal need not be pure aluminium, these may be and probably would be of some alloy too; in both the cases, the melting will produce toxic fumes.

So, along the power supply, I proposed health care for employees working in this enviroment.

For this, I had chosen  PWM 2 click Mikroe Click board.

Then when I started writing this introductory blog in Nov. 2023

Mikroe Click board - PWM 2 click (Initially Selected but Exchanged by other board ECG)

I initially selected this Mikroe Click Board, thinking of using it to switch at 1 MHz.  The main page of the specification do not mention anything about output switching frequency.

But when I started writing blog and started calculations from datasheet, I found the frequency is only upto 6.1 kHz and when I wanted to implement 1 MHz.

So, i requested cancellation of my selection.

PWM 2 Click Board is a 48 channel, independently controlled PWM channels board. Each channel has PWM width resolution of 12-bits and PWM correction of 6-bits. This 6-bit correction register is also known as the dot correction register. PWM 2 is able to detect both synchronization errors and open LED errors. It uses 56-Pin (6mm × 6mm × 0.78mm) TLA QFN Package, LT8500.

Remark  : Not Selected and Requested exchange by other board ECG

Problem 2 : Health CheckUp of Engineers/Technicians/Workers in this Recycle Enviroment

Addressing Way : Air Purifier, Oximeter and ECG
