|Raspberry Pi (mine is the 1Gb Quad core 2015 model.)|
|Power Supply with mini USB connector (5V, 2A)|
|One or more, 8 Gb SD cards (you install the operating system on these). Yes, 8 Gb is adequate space.|
|Wifi dongle or ethernet connection (connecting to the internet is essential to install some software).|
|USB Keyboard and Mouse (Essential for the first few weeks, until you learn how to use VNC)|
An HDMI monitor (in most homes; a television). A twee ornament helps the electronic pixies feel more relaxed, thus
improves efficiency and reliability.
A monitor is only needed until you learn how to use VNC. VNC allows you to see the Raspberry Pi screen from your existing computer.
|40 pin GPIO extension board (if you intend to plug things into the GPIO pins). The GPIO pins on the Pi are not labelled, and you do not want to start counting "On the left, seventh pin down from the top, oh hang on, it's upside down"|
|The Pi Camera module is optional of course, but I bought one and I'm surprised at the high quality of the picture. I intend to set up a webpage so that I can record my house and monitor my budgies in real time when I'm away.|
|The plastic case to enclose it; although considered optional, I would strongly recommend it.|
|Breadboard and a variety of other electronic sensors. You can buy a bundled kit of 35 or so sensors (eg on EBay). These are from my arduino; all will work with Pi. Shown: breadboard, 16x2 LCD, 7 Segment LED, sonic distance, GPS tracker, Infra red PIR and a servo motor.|
