2. 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.

4. 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.
6. 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
7. • 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
8. 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
10. Assembly Process
• Slider 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
11. • 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
12. 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
