With Ethernet and two USB ports, the Model B is usually easier to set up. The Model A saves a few bucks and uses less power…but with only one USB port and no Ethernet, it requires some added skill and/or shenanigans to get all the software fully loaded.
- PiTFT Mini Kit — TFT+Touchscreen for Raspberry Pi
- Raspberry Pi Camera Board. For general work you’ll want the regular version. For special projects like security or nighttime nature photography, you can experiment with the infrared version.
- SD memory card, 4GB or larger. To make the camera slimmer and more portable, you can optionally use a microSD card with either our low-profile or Shortening adapters.
The following parts are optional:
- A WiFi adapter allows the camera to upload photos to Dropbox (requires account, free).
- A USB battery pack makes the whole camera portable. If using WiFi and/or a Model B Pi, you’ll want a robust battery pack that can provide 1 Amp (some are limited to 500 mA max).
- In some situations a USB to TTL Serial Cable may be the preferred way to log in and configure the Raspberry Pi, if a spare keyboard and monitor are unavailable.
Some additional parts, tools and skills are also required: soldering iron and solder for connecting the header to the PiTFT display; some means of holding all the pieces together — could be as simple as a few rubber bands, to a drilled-out plastic electronics enclosure, to an elaborate custom 3D-printed case. This all depends on your available resources. Read through to see what’s involved in the project and come up with ideas along the way.
Other Raspberry Pi – Point & Shoot Cameras!
James Wolf made a Raspberry Pi - Point & Shoot Camera all inside the original case (except battery). He made a little board attached to a cut down ribbon cable, just for the pull up resistors and the button - instructions, pictures and a link to the simple Python file are located on his site.
