This instructable explains how I setup a Raspberry Pi to open my garage door using a smarthphone. While this has been done before, I thought I'd post my solution. This was my first hardware project and instructable ever and I'm sure I made some mistakes. So, when you find one let me know! Project Overview: What we will be doing is turning the Raspberry Pi into a small web server. When you access the webserver from your browser of choice, you will have a big button that triggers the garage door via a relay. We will wire a very basic circuit to the Pi's GPIO pins and upload a website that triggers the circuit. When the relay is triggered, it closes the circuit hooked up to the garage motor and opens the garage.Why would anyone want to do this? Well, my garage door opener was broke and this was cheaper than replacing the other system. As an added plus though, you could wire up additional sensors and be able to make sure your garage is closed remotely if your were so inclined.Shopping List: I consider myself pretty cheap, and I tried to keep the costs minimal.
All of the items are available on prime. 1.) Raspberry Pi - Model A - $32 2.) Wifi Adapter - $10 3.) PSU - $5 4.) 5v Relay - $6Total: $53.00 You will also need an sdcard >= 2GB and some wires, but I had extra of each.Step 1: Install and Optimize Rasbian (for our purposes)Show All Items This first step is to install an operating system to your rpi. I'm a bit of a debian fanboy, and had an extra 2GB sdcard, so I went with a shrunk version of Wheezy. On Ubuntu, I used gparted to format to fat32, and dd to write the img. After you install the OS, plug in a usb keyboard and hook up the raspberry pi to a monitor. Assuming you are using Wheezy, on the first boot rasp-config will automatically run. You should use this tool to stretch the parition and enable ssh (under the advanced menu on newer versions I believe). After I installed my img, I also removed the GUI to free up some space. (If you have a large SD, you can skip this.) To do this type these commands:$ sudo apt-get remove --purge x11-common$ sudo apt-get autoremove This removes all packages that depend on X11 which is pretty much all of the GUI.

Latching Relay Module “In electronics, a device is said to be a latching device if it maintains any particular fixed state even after removal of the input signal.
The same also applies for electronic/electromechanical relays. Basically the electromechanical relays that are used today are of two types: 1. Non-Latching Relay : These relays are most widely used where energy consumption is basically not … more ... Pool House Heater Controller “This project started as a way to prevent my pool pump/filter outdoor cupboard from freezing in the winter. I already realized that a 60w lightbulb should be enough heat in such a small volume (2 cubic metres approx), but I wanted a way to control the heating so nothing would melt either ! This is an easy job for an … more ...
