# Mini Raspberry Pi Handheld Notebook
## Overview
https://www.youtube.com/watch?v=9uJA_YbKfn8
This is a Raspberry Pi notebook. Our 3D Printed enclosure turns the Pi and a 3.5” PiTFT into a sweet retro mini laptop. The mini chiclet keyboard is both adorable and wireless. It features a trackpad, but you can also use the Touch screen on the PiTFT.
Rechargable through the PowerBoost 1000C, the 2000mAh battery fits between the screen and the Raspberry Pi. 3D Printed hinges attach to the enclosure, making this a tiny portable computer!
Warning:
## Usage
The best use case for this project is for monitoring and controling prints, checking up on webcams or even streaming music. You can even play text adventures games like Zork!

## Software
The PiTFT requires kernel support and a couple other things to make it a nice stand-alone display. We have a detailed step-by-step setup for hackers who want to tweak, customize or understand the PiTFT setup. If you just want to get going, check out the following for easy-install instructions!
# Ready to go image

## 3D Printing

## 3D Printed Parts
All you need are these seven parts to get started:
- Case
- 4 hinges
- Keyboard case
- Back cover
## Slicer Settings
You can use the settings below as a reference. The parts are oriented in the center of the bed and ready to print "as is". They do not require any support material.
## Materials
These parts have been printed in PLA but should print without any problems in ABS or other materials like bamboo and metal filaments.
## Hinge Assembly
The hinges print with no support material and are held together with a machine screw, nut and friction. You can adjust the tolerance by fastening the machine screw.
## Hinge Connections
The hinges connect like legos. Snap fit each to the screen and keyboard case. The hinge is modular, so you can use these on other projects.

## Circuit Diagram
Take a moment to review the components in the circuit diagram. This illustration is meant for referencing wired connections - The length of wire, position and size of components are not exact.
The PAM8302 amplifier connects to the **+** and **-** sides of the mini speaker. Route power by connecting **VIN** to **5V** on the PowerBoost 1000C and then **Gnd** to **G**.
PowerBoost 1000C hooks up to pins ** #2** (5V) and **#6** (ground) on the Pi.
The slide switch will need to connect to **Ground** and **Enable**.
Battery connects to the JST port next to the USB port on the Powerboost 1000C.
# Mini Raspberry Pi Handheld Notebook
## Assembly
## Making the battery fit
To fit the battey in between the screen and the Pi 2, we'll need to make room by bending the header pins on the PiTFT display.
Use a pair of flat pliers to carefully bend each header pin down, so they're parted like in the photo.
## Prepare battery
Wrap a layer of gaffers tape around the battery to proect it. This will also give it a nice cushion agaisnt any of the pins.
## Battery Sandwich
Carefully mount the PiTFT on top of the Pi. Make sure to positon the battery wire on the opposite side of the USB ports.
## Wire Power
Use two short jumper cables to easily conncet power and ground to the Pi. Power is **GPIO2**. Ground is **GPIO6.**
## Route wires
Neatly nest each wire for the speaker, amp and PowerBoost between the screen and Pi.
## Insert Pi and PiTFT
Place the Pi 2 and 3.5" PiTFT into the enclosure. The ports should line up with the cut outs on the enclosure. The mounting tabs on the display should line up with the standoffs in the enclosure.
## Add Speaker
Insert the mini metal speaker into the enclosure. The speaker fits into the area with sound cutouts and a circular cavity. The speaker will have tight fit, so just press it down to snap it into place.
## Measure each wire
With each wire nested, measure how long you'll need for all of the componets. Make sure to leave a little bit of slack, this will make it easy to open.
## Mount Powerboost 1000C
Secure the Powerboost 1000c to the back cover with two #4-40 3/8 flat phillips machine screws.
## PAM8302 amp
Mount the PAM8302 amp to the side of the enclosure using #4-40 screws. You can solder wires to each pin using a tweezer or solder before mounting.
## PowerBoost 1000C
Solder the PAM8302 amp pins to the PowerBoost 1000C according to the circuit diagram. Positive to **5V** , negative to **ground**.
## Pi Power
If the jumper cables are not long enough, use silicon wires to extend them to the Pi. Leave a bit of slack like before.
Solder the jumper cables to the ground and postive pins on PowerBoost 1000C like shown in the circuit diagram.
## Slide Switch
Mount the slide switch and then take measurements for the length of wires we'll need.
Solder wires to the slide switch and use heat shrink tubing to insulate the connections.
Danger:
Solder these wires to the **enable** and **ground** pins on the Powerboost 1000C.
Almost there! Now we'll just need to route audio to the speaker.
## Pi Audio Input
We can route audio from the headphone jack by directly soldering to the pins on the bottom of the Pi 2. Use a small amont of solder to tin each pin.
## Audio wires
Nest the wiring along the side of the case to avoid covering up the USB ports.
## Battery JST
Connect the 2000mAh lipo battery to the JST port on the PowerBoost 1000C. Turn on the slide switch to check power.
## Mount PiTFT
Use four #4-40 screws to mount the Pi and PiTFT to the case. You may need to bend the side of the case (with the port openings) to allow the Pi to fit into the case.
## Back Cover
Lay the back cover over the enclosure and fasten four #2-56 screws to mount the back cover to the enclousre.
The USB ports are tucked inside the enclosure, so your USB dongles are nicely hidden and out of the away.
The mini chiclet keyboard is both adorable and wireless. It features a trackpad, but you can also use the Touch screen on the PiTFT.
So now you can monitor your printers and remotely kick off a printer or check up on your baby and make sure they’re OK.
You can even jam out for your favorite steam on soundcloud.
**And if you’re looking to play some games, you can easily turn this into a Z Machine and play your favorite retro text adventure games!**
