Progress Milestones
26 to 31 May
- 26 May - Consulted local trainer on my final project
- 26-27 May - Project Timeline Planning
- 27 May
- Decide on what materials I need and created a Bill of Materials (BOM) for the electronics & mechanical components required
- Collected electronic components from Fab supplies
- 27-31 May - Answered questions for Exercise 17
30 May to 3 June
- 30 May - 1 June
- Researched on stepper motors and how to design the circuitry
- Worked on EAGLE on the stepper motor circuitry
- Researched on 4-bar mechanism, namely the Grashof Crank-rocker model
- 30 May - 3 June - PCB Milling machine was out of service. Unable to make any progress on electronics fabrication.
- 1 June
- Designed and lasercut the flipping prototype - version 1, for my project
- Designed version 2 of the flipping mechansim on Corel draw, yet to lasercut
- 2 June - Researched on the housing for my stepper motor - planning to try 3D printing or lasercutting
- 3 June - Researched on the design of my bookstand
6 to 10 June
- 6-8 June - Work retreat out of the country and therefore unable to work on my project
- 9 June
- The PCB milling machine has been repaired and I am planning to mill my board
- Milled my PCB board and stuff the components onto the board
- Uploaded Neil's c code for bipolar stepper motor onto the board using AVRDUDE
- Connected the stepper motor to the board and successfully tested the movement of the stepper motor powered by a DC power supply available in the lab
- Lasercutted version 2 of the flipping mechanism and attached it with the stepper motor.
13 to 17 June
- 13 June
- Borrowed a music stand from a friend to test my prototype
- Programming and testing - making the stepper motor turn in one direction infinitely
- Reading up on AVR programming using C
- 14 June
- 3D printed the housing for the circuitry board
- 14 June - 3D printed the housing for the foot switch
- 15 June - reading up on AVR programming to understand how to add a pushbutton to the programme
- 16 June
- Troubleshoot of C programming with the help of my local instructor; started by just ensuring button was working. Then check that LED is working. Then check the if-else conditions and what was wrong with the codes. We discovered that the input parameters for the function bit_is_clear is incorrect and rectified.
- remade the housing of the PCB circuitry due to warped edges caused by too long a length. Found out the problem could be resolved by adding a brim base structure.
- 3D-printed the round plate of the flipping mechanism
- Explored options to design the end effector to lift the page
- 17 June
- Lasercut version 2 of bookstand design (shifted everything 10cm towards the centre)
- Installation of end effector (blue tac)
- Soldered connecting wires of foot switch
- Inserted foot switch into 3d printed housing
- Assembly of all parts together
- Testing of prototype with a music score
- Troubleshoot stepper motor and end effector issues
- Documentation of project
18 to 22 June
- Documentation of project and update of webpage
- Design of presentation.png page
- Putting a video together of final project
22 June
- Presentation of final project to Neil during class time
27 June - 8 July
- Troubleshoot jittery revolution of the stepper motor
- Troubleshoot end effector
- Refine website and documentation according to course requirements
