Assignment:
In this week I have to propose my final project that integrates the range of units covered, answering what will it do? who's done what beforehand? what materials and components will be required? where will they come from? how much will it cost? what parts and systems will be made? what processes will be used? what tasks need to be completed? what questions need to be answered? what is the schedule? how will it be evaluated?
1)what will it do?
I am planning to make U-FMI ie Ultimaker Filament Measurement Instrument .U-FMI is a device used to measure the length of filament used by the ultimaker during 3D-printing
2)who's done what beforehand?
I got the idea from instructables ,for more details click here.
3)what materials and components will be required?
1)Rotary Encoder
2)Atmega328 board
3)LCD module -LCM S01602DTR/M
4)Push button switch
4)where will they come from?
Atmega328 and LCD display is being obtained from FAB LAB itself. Rotary Encoder was purchaced from makerhive
5)how much will it cost?
| Sl.No | materials | quantity | cost in rupees |
|---|---|---|---|
| 1 | Rotary encoder | 1 | 150 |
| 2 | atmega 328 | 1 | 130 |
| 3 | LCD display | 1 | 440 |
| 4 | resonator | 1 | 60 |
| 5 | 10 k potentiometer | 1 | 10 |
| 6 | Capacitor | 3 | 2 |
| 7 | voltage regulator | 1 | 20 |
| 8 | Tactile switch | 1 | 65 |
| 9 | slide switch | 1 | 54 |
| 10 | Push button | 3 | 30 |
| 11 | jumper wires | 10 | 20 |
| 12 | resistor | 3 | 36 |
| 13 | 9v battery | 2 | 40 |
| 13 | battery clip | 1 | 10 |
| 14 | header pins | 1 strip male and 1 strip female | 30 |
| Total | 1100 |
6) what parts and systems will be made?
pcb board for U-FMI, Box for placing pcb and lcd display and pinion for shaft of the rotary encoder and small case for it
7)what processes will be used?
Machines used for making U-FMI include
Ultimaker 3D printer
Modela CNC
Laser cutter
Vinyl cutter
8)what tasks need to be completed?
The U-FMI is made completely for more details about U-FMI click here
9)what questions need to be answered?
The gear system which I made in my project is only able to give accurate measurement for PLA with grip ,so It is necessary to change the gear system. I think it is better to have a rubber cast over the gear .
10)what is the schedule?
| Sl.No | Activity | Sheduled date | Status |
|---|---|---|---|
| 1 | Components collection | 31 may 2017 | completed |
| 2 | PCB designing | 1 june 2017 | completed |
| 3 | PCB Milling and soldering | 02 June 2017 | Completed |
| 4 | Programming and Testing | 05 June 2017 | Completed | 5 | Case Design and 3D printing | 07 June 2017 | completed | 6 | Integration | 09 June 2017 | completed | 7 | Upadtions or Modifications | 10 June 2017 | completed | 8 | Documentation and poster making | 12 June 2017 | completed |
11)how will it be evaluated?
The U-FMI is being made ,callibrated and integrated with the ultimaker.During callibration 30 cm PLA is pulled through the gap of the gear system and I got accurate reading in the U-FMI.
