fridgepi : leftovers never sounded so good - touch screen refrigerator

I 've been playing music from iPhone to stereo in the basement for years, and the speakers are reconnected to the kitchen.
It works fine, but runs out of battery on my phone and limits content to my iTunes library or some webcasting streams that are a bit of a pain when selecting and playing. FridgePi, enter!
A touch screen Portal powered by Raspberry Pi with access to internet broadcasting and other areas! P. S.
As the fridge magnet fire dog Sparky said, don't forget to plan your escape plan and practice with your family! :)
Sure, I can stick the iPad or Android tablet next to the fridge, but where is the fun of this? ?
Also, it's priceless to see my wife turning her eyes over my other Pi project. :)
When we moved into our house 9 years ago, we had to cut down a small, dead, limbless maple tree, which was left by the builder and could make our lot
I saved some wood from that tree and knew that one day maybe I would have a Pi project to use it. . .
Here we are!
From our first family history, a nice piece of wood is made into a frame of touch screen and Pi.
I would like to give the frame a windcream wood board look to match a very nice coat hook project made by my wife.
I cut the length of the Maple board into two uniform boards, staggered a few inches so that the edges were uneven.
I created the opening for the touch screen by measuring the screen, including the position of the 4 screw tags, and drilled holes for my jigsaw blade, and then cut out the rectangle of the screen.
I drill holes in two pieces of wood and the screw label of the screen is aligned deep enough so that when installed, the glass of the screen is slightly recessed from the surface of the wood (
I want to put a wood edge frame on the edge of the screen).
I use my direct plug router to remove the maple leaf from the two boards where the Pi is located.
I set the depth so the Pi can flush with the back of the maple board so that the GPIO pins don't touch anything and still have enough maple on the front to be strong.
Since the removed Wood area will not be seen once the electronics are installed, I didn't spend much time or effort making the cut beautiful. Plus it was -
19c in my garage
So it was done soon. :)
The second step is to give the frame some characters.
My wife made a very nice hanger a few months ago (see photo)
So I thought I would copy her design and build the bracket in its image.
I love the windcream barn board, but I really don't want the diesel/feces saturated barn board to stick to the side of the kitchen fridge, so I chose to make a fake weathered frame for this project.
It's really easy.
1 Select wood for your frame.
Since the Pi itself would be very close to the surface of the board, I chose to use hardwood floors (maple).
Because we had a maple tree in our backyard, I used the wood of that tree.
So, give item 2 the paint of several colors selected from a personal perspective, and then brush the color onto the board.
Don't cover every inch of the board too crazy.
As shown in the photo, just brush it on the section. I found white(ish)
Good blue and gray.
Tip: Use the paint you already have, or buy a sample tank to save $.
3 Let the paint dry and then lightly polish on the paint layer to form a weathered/worn look.
Once the paint is polished off, the illusion of full Frost is created, and it is time to connect the two boards together.
I fixed the frame plate together with a pin screw at one end, and I used a wooden screw at the other end, which I couldn't see once installed on the fridge. Pre-
Drill the screw holes with a suitable size drill bit to avoid cracking of wood.
After the paint was dry, polished and drilled, I applied dark stains on both boards with cloth.
This gives the frame a classic look.
Again, this is completely open to your own aesthetics.
You can choose to get your frame dirty, dark or light. Once dried (24h plus).
I set the touch screen in the frame to check the depth and positioning. So far so good!
7 "the screen is located around 1mm, blowing the surface of the Maple plate.
The Pi itself is located inside the hollowed out rear of our motherboard, and the HDMI cable connection is well routed between the PI and the screen.
In the next steps, don't forget to peel off the protective film before connecting the edge frame! :)
After verifying the positioning of the screen and cable, I fixed the touch screen in place with 4 small screws.
I used a good ol' PL building adhesive and applied the oblique maple leaf edge frame around the screen with the same stains as wood.
Due to the large screw tag holes on the screen, I chose to place a wooden frame around the screen, covering the holes and any other defects placed on the screen.
The only thing to note is that two of the screw holes extend to the edge of the edge frame.
It's not a big deal because I just covered the two spots with a hard cork and got dirty as well.
In hindsight, I should place two more hard cork on the other side of the screen to produce symmetry. Live and learn. :)
Since FridgePi will live on the side of our kitchen fridge, I chose the magnet as a means to connect it to the fridge. Magnet is right
Destructive and (
If you collect enough old e-crap like me), free! Old 3.
The hard drive is a very powerful gold mine for large area flat magnets.
The fields in the picture are so strong that they can be attached to the other side of my hand.
They may also have additional benefits including screw mounting holes.
So now Interface (FridgePi)
On the side of Project id completion, I installed a Pi with Volumio as the actual music streaming server.
You can view the free Volumio software here: set up Pi 3 with 16 mb SanDisk micro SD card and install the Volumio image into.
I used a hixibunry DAC Plus connected to the GPIO and RCA to connect to my 1994 JVC stereo receiver connected to the speakers of our entire house.
Our music is stored on synoology 1515 and Volumio allows AirPlay as well as thousands of webcasts, which is good because I like to listen to the radio station of the Tao De moscenescenemusic.
My wife does not. . . :)
I set JVC amp to the right max volume and then configure the Pi running Volumio to access my network share iTunes and (
More importantly
Synology NAS for the music folder of DemoScene.
I give Volumio Pi a static IP address and then let it sit headless and connect to my basement network switch.
After configuring the Volumio Pi server, I set up the Pi, which will be the main interface and stuck on the side of the fridge.
The first thing I did was install the latest Raspbian (Stretch)
From the raspberry pie website.
On the first launch, you will notice that the screen image quality looks like garbage. No worries!
All we need to do is manually define the best resolution of 800x400 (
Note that the best resolution of your touch screen may vary).
Do this by editing your configuration.
Txt file in/Boot directory: sudo nano/boot/config.
TxtAdd is as follows: hdmi _ group = 2 hdmi _ mode = 87 hdmi _ cvt = 800 480 60 6 0 hdmi _ drive = 1 save and restart the Pi.
It should look better. :)
Auto-start ChromiumThen, I have to set it to auto-start x and log in with the default user "pi.
After the system automatically logs in and starts the GUI, I set it to automatically load the Chrome web browser
Screen mode at startup and boot it to the Volumio Pi server.
I did the following for this (
Remember, this is stretched)
: Sudo nano/home/pi /.
Configuration/lxsession/LXDE-
Add folliwing line to Pi/autostart: @ lx terminal-e chromium-browser --start-fullscreen --incognito 10. 0. 1. 27Where 10. 0. 1.
Of course, 27 is your own volumio server address.
Removing the mouse cursor on the screen is always annoying, so to remove it we used a small utility called unclutter.
Install unclutter using Terminal: sudo apt-
Install unclutterThen and if it doesn't do this by itself, just edit your autostart file again: sudo nano/home/pi /.
Configuration/lxsession/LXDE-
Pi/autostart and add: @ unclutter-
Now when you actually touch the screen, you only see one cursor.
Please flip the touch screen coordinates if you need to reverse the display (
For example, move it from one side of the refrigerator to the other)
Like me, not only do you need to flip the HDMI image, but you also need touch screen coordinates.
Note: I believe that the actual Raspberry Foundation official 7 "touch screen does not require these steps, which is more important for 3rd party screens.
Like the one I used. :)
Step 1: Flip the HDMI video to edit your configuration.
Txt file located in/boot: sudo nano/boot/config.
TxtAdd the following lines: display _ rotate = 2 180 degreesStep 2: Flip the touch screen coordinate edit File 40-libinput.
Located in conf in/usr/share/X11/xorg. conf.
Dsudo nano/usr/share/X11/xorg. conf. d/40-libinput.
Confuse the existing whole section that references "input class" with an identifier of "libinput touch screen catchall" to make sure it is a touch screen, not the touch pad or tablet section you annotate.
Now, add the following: section "MatchDevicePath" of "MatchIsTouchscreen" of the section "InputClass" identification "libinput touch screen is/dev/input/activity *" driver "evdav" option "transformionmatrix "--1 0 1 0 -
End saving and restart.
This "should" flip the touch screen coordinates. --------------------------------------------------------------------------------------
I hope you enjoyed the instructions!
I was happy making it, and when I printed it out, I listened to it!
I have said to modify this item to include an LED lighting button that will turn the backlight on/off for the screen, and the second button, it allows me to run multiple programs in a loop across a variety of desktops, so FridgePi can be used not only to display Volumio, but also weather reports, refrigerator content tracking databases, family activity calendars, etc. . .
Please keep an eye on more of these new features. . .
Same bat time, same Bat channel!
