This document summarizes an MSc thesis that prototypes a pocket-sized portable computer using a Raspberry Pi single board computer and 3D printing technology. The objectives were to create a portable design that is less expensive and uses less energy than traditional computers. The thesis describes the Raspberry Pi 2 specifications, outlines problems with non-portable designs, and details the electrical components, 3D printed enclosure, assembly process, testing results, and potential future improvements and applications.

MSc Thesis Diploma Portable computer based on single board computer Raspberry PI Author: Yash Sawarkar 232524 Promoter: Dr hab. in甜. Artur Wymysowski
INTRODUCTION The raspberry is a well known as a credit card sized single-board computer that can be plug with a monitor and keyboard. It is based on a SOC (system on a chip) technology processor The main objective of the thesis was to prototype a pocket sized computer using 3D printing technology and avaiable electronic modules, based on Raspberry PI version 2. =
RASPBERRY PI 2 SPECIFICATION
PROBLEM STATEMENT Not portable because of its heavy structure and design, Need of the dedicated platform, Because of its design and hardware requirements it is more costly and consume more electric energy, Repairing and maintaining the traditional computers are costly as comparing to the mini computers, There is no customization of operating systems according to the task; in portable computer we can design an operating system according to the dedicated task, e.g. embedded system.
Electrical part Circuit diagram of the system
POWER BOOST 1000C It contains load sharing circuit that is able to power the circuit and at the same time the recharging It can only be used with rechargeable Li-Po batteries Micro USB input jack is available Low battery indicator LED Battery charging indicator LED : yellow and green
Lithium Polymer Battery was selected Advantages: security and a slim structure Light weight The hardware uses 3.7V & 550 mAh power ratting Li-Po battery POWER SUPPLIES
3D PRINTING It's a method for fast mechanical prototyping. It's a type of computerized manufacture, which is utilizing a PC controlled device to make a physical object. We can make a physical duplicate of our ideas in hours, rather than weeks or days The filament based technique to print our 3D model was used: Ultimaker V3 The print grows from bottom to top, layer by layer until the print is finished
Mechanical Part 3D view of the enclosure (Base case) 3D view of the enclosure (Top case)
Assembly Process 際際滷r switch with the pins that are EN and GND were soldered on the power boost 1000 C. Li-Po battery with power boost 1000 C was connected through JST connector Battery connected to the power boost 1000 C
The system takes 1 hour 30 minutes to charge fully work continuously up to 51 minutes. connecting the peripherals devices e.g. mouse, keyboard, WI-FI drivers and USB it worked continuously up to 44 minutes Comparing size of minicomputer with the traditional Testing and validation
FUTURE SCOPE Customizing Li-Po battery design Development based on Raspberry PI zero W Compact and handy design with increased processing speed Using 1000 mAh Li-Po battery
SPACE APPLICATION Sensing elements: Pressure / Temperature Humidity / Temperature Acceleration/Gyroscope/Magnetic field Finding directions
