My Raspberry Pi Powered Garage Monitor

Update #1: Garage Monitor Memory Leak: Part 1. Update #2: I should point out that the arm on the switch I ended up using bent so it stopped working after about a month of use. I really need to figure out a way to mount the magnetic switch instead. I added a rough parts list to the end of this article. This project uses a switch and temperature sensor connected to a Raspberry Pi (revision 2 board) to provide ...

Switching mains electricity with a Raspberry Pi and a remote control

Home electronics can open up a new dimension in home automation especially when used with an Arduino or Raspberry Pi. There is however a very real danger when using mains electricity, including risk of electricution and danger of electrical fires if the components are not rated correctly. See this guide on risks when working with electricity. This design greatly reduces any risk by avoiding the mains electr ...

Tweeting coffee machine using Raspbery Pi

Observing that LED will give us knowledge if it is being used or not. I am using a Light Dependent Resistor (LDR) as eyes for the Raspberry Pi. The LDRs change their resistance as per the intensity of light falling upon them. Our goal is to register the LED being lit by driving a GPIO pin on the Raspberry Pi LOW. Below is the schematic of my setup: It is a voltage divider, with a weak pull up provided by a ...

Raspberry Pi Fridge Minder: receive an email when the door is opened

The kit comes with project cards and a link to download the accompanying Python scripts. And projects already include a light meter and email notifier, so I decided to combine these two projects into one and make something that will send an email whenever the fridge door is opened. This is particularly timely as the MonkMakes team are trying to loose some weight at the moment. The paper template on the Rasp ...

Arduino watches for a kitchen catastrophe

I guess I should start by admitting that this article was inspired by my own stupidity. When I was a kid, I left a frying pan on a lit stove. I was probably confused by the tactile controls on the vitroceramic hob. Unfortunately, I unwittingly turned the stove up to maximum. Thinking I had actually turned it off, I went to watch TV. Some minutes later, the living room started filling with smoke. To make a l ...
