I've got about 6 varying from Model A to this. I also have many many Arduino's and Arduino minis.
How many PIs do you have?
Do I need it? - No! Did I order it? - Of course I did! (lol)
For people asking what they can be used for. This is what I use my various pi's for. VPN server. Access your home network securely from anywhere in the world. Do not need to open ports to the world if you are running CCTV IP cameras etc. Can access router and any devices in home network. Also when out and about using WiFi hotspots for example, you can connect to your home VPN for secure browsing and bypassing any geographical restrictions (watching iPlayer/Netflix UK or something abroad). Samsung smart TV controller. One of my pi's runs a small script which allows it to be linked to Amazon Alexa so I can control my TV. "Alexa turn off/on the TV" "Change channel/volume" etc etc. LED light controller. Infrared sensor connected to pi picks up movement and controls an LED strip with a script. Home security. Infrared sensor in porch detects movement and sends radio signal to pi which sends email to myself. (I already have CCTV which does this but hey I like making pointless stuff). Also have a pi zero connected to a camera running motion pi. Can stream the image wirelessly. Wake on LAN. One of my pi's has a wake on LAN script running as a web server which allows me to wake my pc up when I input the password. I do various other complicated things which I won't go into. They are great learning tools and we make stuff not because it's tremendously useful but because we can!
Thinking of getting this,is this a UK based company ( just thinking of postage time that's all) cheers
