#Week 13 / Applications and Implications

Assignment and learning outcomes.

What is this week assignment?

We should propose a final project masterpiece that integrates the range of units covered.

  • Your project should incorporate 2D and 3D design
  • Additive and subtractive fabrication processes
  • Electronics design and production
  • Microcontroller interfacing and programming
  • System integration and packaging
  • Where possible, you should make rather than buy the parts of your project
  • Projects can be separate or joint, but need to show individual mastery of the skills, and be independently operable

  • What is learning outcomes for this week?

  • Define the scope of a project
  • Develop a project plan

  • For this week I need to answer this questions.

  • what will it do?
  • who has done what beforehand?
  • What will you design?
  • what materials and components will be used?
  • where will they come from?
  • how much will they cost?
  • what parts and systems will be made?
  • what processes will be used?
  • what questions need to be answered?
  • how will it be evaluated?
  • Assignment.

    Introduction

    My device is wireless charging desk it will charge quite a few devices at the same time using magnetic induction wireless charging method. This method has these advantages and key technology challenges. It will charge any device which has wireless charging capability. You can place your device anywhere on the surface of the desk and it will charge your device (phone, tablets, computers).I have done some research about wireless charging implementations, and I didn't find wireless charging desk which has fully wireless charging ability.

    For final project I will use following components and materials.

  • For 3D printing I have used white PLA material(Makerbot PLA)-100g
  • MDF - 500x300mm
  • Playwood-700x700mm
  • 2 layer boards-4 lists
  • Bluetooth module HC-05-1
  • Monochrome 0.96" 128x64 OLED graphic display-1
  • Atmega328P-1
  • Attiny44a-8
  • NE555 timer-8
  • N chanal MOSFET transistor(RFD16N05LSM)-8
  • Termistor-8
  • Voltage Regulator 5V 55TOL53B-8
  • 22uf electrolitic capasitor(SMD)-9
  • ACS712 current mesuring sensor-1
  • Copper wire -0.5mm- 10meter
  • Wiers and connectors
  • Crystal resonator, resistors , ceramic capasitors in SMD package

  • Steps to follow for final project

  • Step 1) Make wireless power transmiter board with his coil.
  • Step 2) Make Master board for data collection , Bluetooth communication and LCD status showing
  • Step 3) Make Power supply for desk
  • Step 4) Make Boxes for wireless power transmiter board
  • Step 5) Make Desk for Boxes.
  • Step 6) Wiring
  • Step 7) Programming and testing

  • Processes I will use

  • 2D and 3D design for Desk for Boxes(for wireless power transmiter board )
  • Additive fabrication processe -Boxes using 3D printer
  • Subtractive fabrication processe- Desk for boxes using Shopbot CNC
  • Electronics design and production- Master and slave , using KiCad as design tool and SRM-20 as milling machine
  • Microcontroller interfacing and programming- program for slave and master board
  • Assemble all parts
  • Test
