It said it was open for 5 minutes as a warning to let me know that I might have forgotten to close it. Actually I had purposefully left it open to test a device I built based on a couple blog entries from Richard L. Lynch. Now I don’t know Richard, but I found his postings when searching for a solution to absent mindedly leaving the garage door open. Since we have smart phones on us at all times, a simple e-mail from the garage door would be great if it was open for too long. Richard came up with an elegant solution using a Raspberry Pi and a small Python program hooked up to a garage door sensor. The posts could use some updates for the current Raspberry Pi model B+ but they work. Here are the 2 posts by Richard.
You won’t need to USB hub with the B+ model since it has plenty of USB ports. I used CAT 5 cable to connect the sensor to the Pi in the basement. I chose the basement to mount the Pi since it will be out of the elements and kept cool for the most part.
I’m planning on getting another Pi so I can load Mono on it and write the code in C# which is what I’m used to.
Something I’m bad about is rotating canned goods. After looking around I found a company that sells some cardboard ones here: http://canorganizer.com/ I also found some made of plastic and full blown metal ones here: http://www.thrivelife.com/food-rotation-systems I wanted something strong but didn’t want to spend a ton of money either so I came up with my own plan.
I still have a couple more to make. For anyone else who has some woodworking skills and wants to make some the plans I used are all included below with lots of pictures.
