=== An instant camera based on RaspberryPi and a Thermal Printer, in a 3D printed case
Video : https://www.youtube.com/watch?v=Hd7LKRB63qI
Parts needed:
RaspberryPi, Model B (not plus) - http://www.raspberrypi.org/products/model-b/
RaspberryPi camera module - http://www.raspberrypi.org/products/camera-module/
PiTFT - 2.8" TFT touch screen - http://www.adafruit.com/product/1601
Mini Thermal printer - http://www.adafruit.com/product/597
BPA-Free thermal paper (see warning below)
2 or 3 cell Lipo battery, somewhere between 1000 and 2000mah.
Switching power regulator, like the LM2596HV
Total cost is about $100
This project is a work-in-progress. Expect things to not fit perfectly and tinkering is required to get it going.
The code was based on Adafruit's camera example

Follow tutorial to install camera libraries.
And AdaFruit's thermal paper printer

Follow tutorial to intall printer libraries.
About the battery, I used a beefy 3 cell 2000mah bettery, and the camera would run for 3-4 hours off that. The design does not include any method to charge the battery, so you might want to add that or get a lipo charger.
WARNING - Regular Thermal paper contains insane amounts of Bisphenol-A, which is an Endocrine Disruptor. This is especially bad for young children. Please invest in some BPA-free thermal paper. They do exist.
Have fun !
