When I tested the PIR sensor for the first time it worked like a charm. Each of these contains simple tvservice command and everything would be easy-peasy if there wasn’t that HDMI/VGA babble. Now, this is an interesting part: monitor is turned on/off by calling a shell scripts monitor_on.sh and monitor_off.sh. The script basically reads the sensor state from the 7th GPIO pin and depending on its state and the time since the last activity it turns on or off the monitors. Subprocess.call(& amp quot sh /home/pi/Documents/PIR/monitor_off.sh& amp quot, shell=True) Subprocess.call(& amp quot sh /home/pi/Documents/PIR/monitor_on.sh& amp quot, shell=True) If not turned_off and time.time() & amp gt (last_motion_time + SHUTOFF_DELAY): Simple Python script can easily access those pins and read out the PIR sensor’s state. I connected mine to 26th pin of the header which corresponds to the 7th GPIO port. You can use R Pi’s general purpose input/output pins (GPIO) to connect the sensor. Adafruit has a pretty helpful tutorial on these thingies. It has only one output pin that is logic high (3.3V) when the motion is detected and low (0 V) otherwise. It usually comes on a board with a regulation circuitry, BISS0001 motion detector IC, and plastic cap that focuses the radiation. So it senses your body heat when you move around. There are many options of motion detection, and the most popular one is arguably a PIR sensor which is basically an IR sensitive JFET. Well done! Adding a motion detector HC-SR501 PIR motion detector I used If needed, you can rotate your screen (if you use it in vertical mode) by adding "DISPLAY_ROTATE=1" in /boot/config.txt (I didn’t need it).Īt this point you should have the R Pi running the Michael’s code with your private settings. ![]() You can also disable the cursor showing in the middle of your screen by installing unclutter ( sudo apt-get install unclutter). It will also disable the screen going off eventually. I used Midori as web-browser, and I edit /home/pi/.config/lxsession/LXDE-pi/autostart to include commands s s -e Fullscreen -a that will ensure that R Pi opens a Midori browser on your homepage in fullscreen mode right after it boots up. Set R Pi to boot to a fullscreen web-browser.var feed = '' to RSS feed of your choice.'q':'Baarn,Netherlands' to 'q':',' to city and country where you live.APPID to the open weather map api key of your choice.var lang = 'nl' to the language of your choice ( var langn = 'en' makes it english).open MagicMirror/js/config.js and change the following lines:.open MagicMirror/calendar.php and put a calendar of your choice (change the URL in 4th row to your own iCal address).Now adapt his code to match your private settings:.Download Michael’s code from github repository into /var/Looks neat, isn’t it?.Set up an apache2 server on your R Pi and install php5 (if any of these doesn’t go smoothly, try some.Set up a Raspbian (Jessie) on your R Pi, enable SSH, WiFi auto connect, and boot in Desktop mode (may the Google be with you).Here comes the fast run-through on how to set up Michael’s mirror. The Magic Mirror software is basically a web-browser displaying a delightfully designed php page on a local server running on R Pi. Two-way mirror and a wooden frame for it.Raspberry Pi (any version), accompanying SD card and a WiFi dongle.So, let’s get started! The things I needed: Perhaps the most useful tutorial for beginners is the one I found on reddit, by user The-Bent that shows an ultimate how-to guide on Michael’s mirror. Michael Teeuw also provided a step-by-step tutorial on how to set-up his Magic Mirror and gave his code for everybody to use. There are plenty of tutorials on how to set up a Raspberry Pi, install Linux a system and get it started. That’s why I decided to incorporate a simple motion detector to turn the mirror on and off, depending on whether there is somebody in the house. The only issue I had with it is that it is always on, even when there is noone around – which can be quite troublesome for your electricity bill. time, forecast, news etc.) in a very stylish-looking way and gives your home a classy appeal. What better way to learn it than by trying out some DIY project? One of the most popular ones I’ve found around is brilliant Magic Mirror by Michael Teeuw: it’s a mirror that displays some useful info (in.e. Time to configure the interface for your location and needs! cd ~/MagicMirrorĬhange both the "currentweather" and "weatherforecast" weather module settings to your location.I’ve had a desire to learn to work with Raspberry Pi since, like, forever. ![]()
