connect raspberry pi to tft lcd quotation

Hello all, I am new to RPi and am working on a project where I want to use an LCD touch screen that I recovered from another device. I am struggling to figure out how to know which driver board I need to connect it to the RPi. I have the model number of the LCD which is LB080WV3-B1. I also was able to find the specifications of the panel from the manufacture which is located here: https://datasheetspdf.com/pdf/721772/LG/LB080WV3-B1/1

I don"t know what I am supposed to be looking for on the spec sheet to tell me which controller driver I can use. I have done a bunch of googling to try and figure it out but am more confused now than when I started. Can anyone offer any guidance or explain how to find the LCD controller that I need?

As it is an RGB interface you can directly connect it to the Raspberry DPI interface (https://www.raspberrypi.org/documentati ... /README.md) without "glue logic".So, what you will need is an adapter board which converts the 40pin GPIO (2.54mm pitch) interface to 0.5mm FFC. In addition you will need to input the timing (page 10) to let the RPI now how to drive the display.

This is what the above setup looks like "in action". That 5.6in display is 640x480pixels native resolution. I"m running KMS graphics driver which allows me to scale my desktop to 1024x768pixels which still has a good readability on the display (xrandr --output DPI-1 --primary --scale 1.6x1.6)

Thank you sooooo much for the detailed explanation!!!!! One follow up question, not sure what you mean by the "backlight inverter". The LCD has another two channel (red/black) wire sticking out of it that I am assuming is the power cable for the backlight. Is that what you are referring to? If yes, where is that supposed to be connected to on the RPI? or do I just need to connect it to an external power supply?

On 2-lane MIPI you can run 1280x800 pixels with ease, 3-lane is just enough (but tight) for 1920x1080pixels and 4-lane, well depends what you can get.

This is a 7in with 1280x800 pixels running happily (finally now) via MIPI interface from a CM4 (tested with 2- and 3-lane config, 4-lane would be nice for lowest EMI but fails)

Note: DSI to RGB chip used on the RPI display is EOL; so there is the chance that we will see a new official display in the future (but also a risk that RPi decided to make a last-time-buy with huge quantaties in orderto be able to ship longer).

this additional connector is the input to the CCFL backlight lamp. CCFL require high voltage to operate and the device which is used to drive them is usually called an inverter. Below is an example picture:

if you did not/been unable to salvage that component from your display donar device you need to find a new one (extra costs, different specs, ..). And..there is still the risk the backlight fails on first start attempt!

Simplest use of a DPI display is by adding the timing to `panel-simple.c", write an overlay which uses it, compile everything and then add the overlay to config.txt. No need to write any driver.

The TFT isn’t ‘plug & play’ with the Raspberry, a patch has to be applied to the kernel to be able to interface via SPI with the ST7735R controller chip on the TFT. Once working, the display will act as a framebuffer device.

As it takes over three hours to compile the kernel on the PI, I will show how to cross compile from another Linux PC. In my case, it is Ubuntu 12.10 running within VMWare on a Windows 7 Quad core PC. Kernel compile time is 15 mins.

-Copy config from the Raspberry Pi to the Ubuntu box using SCP. Replace ‘raspberrypi’ below with the IP address of your Raspberry Pi if hostname lookup fails.

If you are planning on displaying the console on the TFT, then enabling these options in .config will allow you to change the font size and rotate the display later on.

To enable parallel processing for a faster compile. If you have a dual core processor add -j 3 to the end of the command below. If you have quad core, add -j 6

The last step below is to SCP the files from from Ubuntu to the Raspberry Pi. If you have trouble SCPing into your Ubuntu box you may need to install open SSH on Ubuntu with sudo apt-get install openssh-server. This step also copies the files from my home folder ‘mark’… yours would be different.

If you build the st7735 driver pair as built-in, add these options to the end of the line in /boot/cmdline.txt. This will display the console on the TFT.

Raspberry Pi is a Palm Size computer that comes in very handy when prototyping stuff that requires high computational power. It is being extensively used for IOT hardware development and robotics application and much more memory hunger applications. In most of the projects involving the Pi it would be extremely useful if the Pi had a display through which we can monitor the vitals of our project.

The pi itself has a HDMI output which can be directly connected to a Monitor, but in projects where space is a constrain we need smaller displays. So in this tutorial we will learn how we can interface the popular 3.5 inch Touch Screen TFT LCD screen from waveshare with Raspberry pi. At the end of this tutorial you will have a fully functional LCD display with touch screen on top of your Pi ready to be used for your future projects.

It is assumed that your Raspberry Pi is already flashed with an operating system and is able to connect to the internet. If not, follow the Getting started with Raspberry Pi tutorial before proceeding.

It is also assumed that you have access to the terminal window of your raspberry pi. In this tutorial we will be using Putty in SSH mode to connect to the Raspberry Pi. You can use any method but you should somehow be able to have access to your Pi’s terminal window.

Connecting your 3.5” TFT LCD screen with Raspberry pi is a cake walk. The LCD has a strip of female header pins which will fit snug into the male header pins. You just have to align the pins and press the LCD on top of the Pi to make the connection. Once fixed properly you Pi and LCD will look something like this below. Note that I have used a casing for my Pi so ignore the white box.

For people who are curious to know what these pins are! It is used to establish a SPI communication between the Raspberry Pi and LCD and also to power the LCD from the 5V and 3.3V pin of the raspberry Pi. Apart from that it also has some pins dedicated for the touch screen to work. Totally there are 26 pins, the symbol and description of the pins are shown below

Now, after connecting the LCD to PI, power the PI and you will see a blank white screen on the LCD. This is because there are no drivers installed on our PI to use the connected LCD. So let us open the terminal window of Pi and start making the necessary changes. Again, I am using putty to connect to my Pi you can use your convenient method.

Step 2: Navigate to Boot Options -> Desktop/CLI and select option B4 Desktop Autologin Desktop GUI, automatically logged in as ‘pi’ user as highlighted in below image. This will make the PI to login automatically from next boot without the user entering the password.

Step 3: Now again navigate to interfacing options and enable SPI as show in the image below. We have to enable the SPI interface because as we discussed the LCD and PI communicates through SPI protocol

Step 4: Click on this waveshare driver link to download the driver as a ZIP file. Then move the ZIP file to you PI OS. I used Filezilla to do this, but you can also use a pen drive and simple copy paste work.  Mine was placed in the path /home/pi.

Step 7: Now use the below command to restart your Pi. This will automatically end the terminal window. When the PI restarts you should notice the LCD display also showing the boot information and finally the desktop will appear as shown below.

You can also watch the video below to check how the LCD is connected and how it responds to touch. I am pretty much satisfied with its default accuracy so I am not going to do any calibration. But if you are interested you can view the official wiki page from waveshare where they discuss how to calibrate and enable camera view on the LCD screen.

Hope you understood the tutorial and were successful in interfacing your LCD with PI and got it working. If otherwise state your problem in the comment section below or use the forums for more technical quires.

Rather than plug your Raspberry Pi into a TV, or connect via SSH (or remote desktop connections via VNC or RDP), you might have opted to purchase a Raspberry Pi touchscreen display.

Straightforward to set up, the touchscreen display has so many possibilities. But if you"ve left yours gathering dust in a drawer, there"s no way you"re going to experience the full benefits of such a useful piece of kit.

The alternative is to get it out of the drawer, hook your touchscreen display to your Raspberry Pi, and reformat the microSD card. It"s time to work on a new project -- one of these ideas should pique your interest.

Let"s start with perhaps the most obvious option. The official Raspberry Pi touchscreen display is seven inches diagonal, making it an ideal size for a photo frame. For the best results, you"ll need a wireless connection (Ethernet cables look unsightly on a mantelpiece) as well as a Raspberry Pi-compatible battery pack.

Several options are available to create a Raspberry Pi photo frame, mostly using Python code. You might opt to script your own, pulling images from a pre-populated directory. Alternatively, take a look at our guide to making your own photo frame with beautiful images and inspiring quotes. It pulls content from two Reddit channels -- images from /r/EarthPorn and quotes from /r/ShowerThoughts -- and mixes them together.

Rather than wait for the 24th century, why not bring the slick user interface found in Star Trek: The Next Generation to your Raspberry Pi today? While you won"t be able to drive a dilithium crystal powered warp drive with it, you can certainly control your smart home.

In the example above, Belkin WeMo switches and a Nest thermostat are manipulated via the Raspberry Pi, touchscreen display, and the InControlHA system with Wemo and Nest plugins. ST:TNG magic comes from an implementation of the Library Computer Access and Retrieval System (LCARS) seen in 1980s/1990s Star Trek. Coder Toby Kurien has developed an LCARS user interface for the Pi that has uses beyond home automation.

Building a carputer has long been the holy grail of technology DIYers, and the Raspberry Pi makes it far more achievable than ever before. But for the carputer to really take shape, it needs a display -- and what better than a touchscreen interface?

Ideal for entertainment, as a satnav, monitoring your car"s performance via the OBD-II interface, and even for reverse parking, a carputer can considerably improve your driving experience. Often, though, the focus is on entertainment.

Setting up a Raspberry Pi carputer also requires a user interface, suitable power supply, as well as working connections to any additional hardware you employ. (This might include a mobile dongle and GPS for satnav, for instance.)

Now here is a unique use for the Pi and its touchscreen display. A compact, bench-based tool for controlling hardware on your bench (or kitchen or desk), this is a build with several purposes. It"s designed to help you get your home automation projects off the ground, but also includes support for a webcam to help you record your progress.

The idea here is simple. With just a Raspberry Pi, a webcam, and a touchscreen display -- plus a thermal printer -- you can build a versatile photo booth!

Various projects of this kind have sprung up. While the versions displayed above uses a thermal printer outputting a low-res image, you might prefer to employ a standard color photo printer. The wait will be longer, but the results better!

Projects along these lines can also benefit from better use of the touchscreen. Perhaps you could improve on this, and introduce some interesting photo effects that can be tweaked via the touchscreen prior to printing?

How about a smart mirror for your Raspberry Pi touchscreen display project? This is basically a mirror that not only shows your reflection, but also useful information. For instance, latest news and weather updates.

Naturally, a larger display would deliver the best results, but if you"re looking to get started with a smart mirror project, or develop your own from scratch, a Raspberry Pi combined with a touchscreen display is an excellent place to start.

Many existing projects are underway, and we took the time to compile six of them into a single list for your perusal. Use this as inspiration, a starting point, or just use someone else"s code to build your own information-serving smart mirror.

Want to pump some banging "toons" out of your Raspberry Pi? We"ve looked at some internet radio projects in the past, but adding in a touchscreen display changes things considerably. For a start, it"s a lot easier to find the station you want to listen to!

This example uses a much smaller Adafruit touchscreen display for the Raspberry Pi. You can get suitable results from any compatible touchscreen, however.

Alternatively, you might prefer the option to integrate your Raspberry Pi with your home audio setup. The build outlined below uses RuneAudio, a Bluetooth speaker, and your preferred audio HAT or shield.

Requiring the ProtoCentral HealthyPi HAT (a HAT is an expansion board for the Raspberry Pi) and the Windows-only Atmel software, this project results in a portable device to measure yours (or a patient"s) health.

With probes and electrodes attached, you"ll be able to observe and record thanks to visualization software on the Pi. Whether this is a system that can be adopted by the medical profession remains to be seen. We suspect it could turn out to be very useful in developing nations, or in the heart of infectious outbreaks.

We were impressed by this project over at Hackster.io, but note that there are many alternatives. Often these rely on compact LCD displays rather than the touchscreen solution.

Many home automation systems have been developed for, or ported to, the Raspberry Pi -- enough for their own list. Not all of these feature a touchscreen display, however.

One that does is the Makezine project below, that hooks up a Raspberry Pi running OpenHAB, an open source home automation system that can interface with hundreds of smart home products. Our own guide shows how you can use it to control some smart lighting. OpenHAB comes with several user interfaces. However, if they"re not your cup of tea, an LCARS UI theme is available.

Another great build, and the one we"re finishing on, is a Raspberry Pi-powered tablet computer. The idea is simple: place the Pi, the touchscreen display, and a rechargeable battery pack into a suitable case (more than likely 3D printed). You might opt to change the operating system; Raspbian Jessie with PIXEL (nor the previous desktop) isn"t really suitable as a touch-friendly interface. Happily, there are versions of Android available for the Raspberry Pi.

※Price Increase NotificationThe TFT glass cell makers such as Tianma,Hanstar,BOE,Innolux has reduced or stopped the production of small and medium-sized tft glass cell from August-2020 due to the low profit and focus on the size of LCD TV,Tablet PC and Smart Phone .It results the glass cell price in the market is extremely high,and the same situation happens in IC industry.We deeply regret that rapidly rising costs for glass cell and controller IC necessitate our raising the price of tft display.We have made every attempt to avoid the increase, we could accept no profit from the beginning,but the price is going up frequently ,we"re now losing a lot of money. We have no choice if we want to survive. There is no certain answer for when the price would go back to the normal.We guess it will take at least 6 months until these glass cell and semiconductor manufacturing companies recover the production schedule. (Mar-03-2021)

All the accessories listed below tier pricing need to pay.We won"t deliver until you select. Power adaptor should be 5V/2000mA in output and center pin for positive voltage and the outer shield for negative voltage .The temperature for controller RTD2660 would increase during working.That"s normal phenomenon,not quality problem.

ER-TFTV050A1-1 is 480x272 dots 5" color tft lcd module display with small HDMI signal driver board,optional capacitive touch panel with USB controller board and cable and 4-wire resistive touch panel with USB driver board and cable, optional remote control,superior display quality,super wide view angle.It can be used in any embedded systems,car,industrial device,security and hand-held equipment which requires display in high quality and colorful video. It"s also ideal for Raspberry PI by HDMI.

This project uses the SPIFFS (ESP32 flash memory) to store images used as background. You"ll need to upload these to the ESP32 before you upload the sketch to the ESP32. For this you"ll need the ESP32 Sketch Data Upload tool.

You can download this from Github: "https://github.com/me-no-dev/arduino-esp32fs-plugin". Follow the instructions on the Github to install the tool:Download the tool archive from releases page.

Before you upload the data folder to the ESP32, you"ll first have to select the right partitioning scheme.Go to Tools -> Board and select ESP32 Dev Module.

On Github you can find the full source code for this project. Go to the Bluetooth-System-Monitor Github repository and click "Code" and "Download .ZIP": https://github.com/DustinWatts/Bluetooth-System-M...

Extract and rename the extracted folder to "Bluetooth-System-Monitor". This is so the Arduino IDE does not complain that the folder and the sketch do not have the same name. If this happens, you will get a popup asking you if it should move the sketch. The dangerous thing here is, that it will only move the sketch and not the Data folder. This will result in errors when uploading!

Firstly, depending on the board you are using (with resistive touch, capacitive touch, or no touch) you will have to uncomment the correct one. For example, if you are using the ESP32 TouchDown uncomment: "#define ENABLE_CAP_TOUCH". If you are using a DevKitC with separate TFT, uncomment "#define ENABLE_RES_TOUCH".

You can also set the scale of the y-axis of the graphs. This is done under "// The scale of the Y-axis per graph". If these are to big or to small, the data will not be displayed correctly on the graph. You might have to experiment with these.

Go ahead and upload the Bluetooth-System-Monitor.ino sketch to the ESP32. The settings under tools besides the Partition Scheme can be left to the default (see image). Go to "Sketch" and select "Upload". This may take a while because it is a large sketch.

One of the most awaited plugins for Volumio is finall here: the touchscreen plugin. With it you can easily show the gorgeous Volumio UI on any display, included the official Raspberry PI Display, available on our Shop. Let’s see how to easily achieve a fantastic touchscreen for your favourite music player in less than 10 minutes. This tutorial will explain how to connect the Raspberry PI display and enable the Volumio UI with the plugin.

Assuming you’ve already downloaded and flashed Volumio to your Raspberry PI (we suggest to use the newest  Raspberry PI 3), the first step is the wiring:First, let’s attach the ribbon cable going from the Raspberry PI Display to the PI itself. On the Raspberry PI Side, make sure the blue part of the ribbon cable is facing outwards. Your final goal should look like this:

You’ll have 4 coloured cables to connect too. They are 5v, GND, SDA and SCL. You can look at the below image to identify the proper pin on the Pi itself.

Notoriously, feeding your PI with an adequate Power Supply is mandatory to have a reliable system. That’s especially true when we connect a power-hungry device like the Raspberry PI Display. Luckily, there’s a way to understand if your PSU is good enough: just power on your pi and observe the screen, if you see a coloured square on the top-right side of the screen, it means that power to your PI is not enough. Don’t you see it? Then all is good.

That’s the easy one. Just connect to Volumio’s WebUi as you would usually do, and navigate to the Plugins page from the settings menu. In Miscellanea category, you’ll find the Touchscreen plugin. Just click install, nothing more. PLEASE NOTE: The touchscreen plugin is compatible with volumio version from 2.001 onwards

The installation will last about 7 minutes, so wait patiently until you see “Installation Complete”. Now you can enable or disable the Display output to your likings.

I must admit that altough this display is not particularly brilliant when it comes to resolution and colour accuracy, it looks indeed very nice with Volumio’s UI. Also, usability is very good on the Raspberry PI 3 and the UI runs smoothly also with big libraries… So, folks, enjoy!

If you don’t have a Raspberry PI, or you’re simply looking for alternatives to the Official Raspberry PI Display, there are at least two extra options for you:

The Odroid display is not only a viable alternative, it also have several advantages over its PI counterpart:Since it takes power from USB and video signal from HDMI, it can be used virtually with any Computer with an HDMI output, not just the Odroid or the Raspberry PI.

UPDATE: Lot of time since I published the original article. The Odroid 7” does not seem to work properly with Raspberry PI (not tested with the Odroid). So, if you’re looking for a display for the Raspberry PI, get the official one.

The Waveshare 7” display has become rapidly a widely adopted display, thanks to its cheap price. However this particular touchscreen has shown several reliability issues (altough this seems fixed in latest models, thanks to a firmware update), it requires a particular touchscreen driver which is not always included in major distros and its colour reproduction is not the best.

Here we are folks! Hope you found this article helpful, you can share via comment below how you use your Volumio’s touchscreen setup and if there are other display alternatives!

In the previous article, I described the steps needed to install an LCD touchscreen on the Raspberry Pi. In this article, I will show you how to adjust the screen rotation of the LCD to landscape mode, and will show you how to calibrate the touchscreen pointer for optimal accuracy. Just follow the steps below to compete the process of setting up your Raspberry Pi LCD touchscreen:

1. First we need to change the setting for screen rotation in the /boot/cmdline.txt file. This setting is called fbtft_device.rotate=X. By default, this is set to X=0, which results in a portrait mode screen orientation. In order to switch the orientation to landscape mode, change fbtft_device.rotate=0 to fbtft_device.rotate=90. Enter sudo nano /boot/cmdline.txt at the command prompt. There should only be one line in this file. Go to the end of it and you will find the fbtft_device.rotate=X setting. Change the value from 0 to 90:

However, if you try to touch the screen now, you will find that the pointer movement does not correspond to your finger movement. This is because the LCD screen driver and the touchscreen controller driver have separate settings for screen rotation. We need to change the rotation of the touchscreen controller driver to match the rotation of the LCD screen driver.

2. You probably noticed that dragging your finger to the right moves the pointer up, not to the right. This indicates that the x and y axes of the touchscreen are swapped. To correct this, we need to swap the x axis for the y axis. This can be done by changing the swap_xy=X parameter in /etc/modules.

Enter sudo nano /etc/modules at the command prompt to edit the file. Go to the line for the ads7846_device parameters and move the cursor to the right to find it:

Now if you drag your finger around the screen, you will notice that the y axis (up and down) is correctly aligned with the motion of your finger. However, the x axis (left and right) is still inverted. To fix this, we need to install two more kernel modules, xinput and evtest. xinput is a Linux utility that will allow us to configure input device settings for the touchscreen controller, and evtest is an input device event monitor and query tool.

After the Pi finishes rebooting, you should notice that when you move your finger across the touch screen, the pointer should follow correctly in both axes. If you are using the Raspberry Pi 2 Model B, you will need to complete the calibration steps below before the pointer follows your finger correctly (and make sure that you have enabled startx to load automatically – see step 6 in this article).

You can rotate the screen 90 degrees (as we did in this tutorial) and the power connector will be at the bottom of the screen, but you can also rotate it 270 degrees so that the power connector is at the top of the screen. To do this, simply enter fbtft_device.rotate=270 in the /boot/cmdline.txt file. Then change the DISPLAY=:0 xinput --set-prop "ADS7846 Touchscreen" "Evdev Axis Inversion" 0 1 line in the /etc/X11/xinit/xinitrc file to DISPLAY=:0 xinput --set-prop "ADS7846 Touchscreen" "Evdev Axis Inversion" 1 0. All you need to do is switch the values of the 0 and 1 at the end of this line.

Now that we have our LCD touchscreen up and running, the final step in the installation is the calibration of touch control. This will make the pointer much more accurate and easier to use.

2. Now we need to install the calibration tool we will be using, xinput_calibrator; and other filters for controlling the touchscreen response. Install the tslib library by entering aptitude install libts-bin:

This will create a configuration file called /etc/ts.conf, which contains settings for variance and jitter that can be changed to optimize pointer response. See here for information about configuring ts.conf.

3. The calibration tool we will use is called ts_calibrate. We will also be using a program to check the results of the calibration called ts_test. In order to use ts_calibrate and ts_test, we must first set proper environmental variables. Enter export TSLIB_TSDEVICE=/dev/input/event0 into the command prompt, then enter export TSLIB_FBDEVICE=/dev/fb1:

4. Now we can use ts_calibrate. Enter ts_calibrate at the command prompt (make sure you are still in root mode) to run the ts_calibrate program. The program will consecutively display five crosses on different parts of the screen, which you need to touch with as much precision as possible:

This calibration data will be written to a calibration file called /etc/pointercal. To view the contents of this file, enter cat /etc/pointercal at the root command prompt.

Drag the cross around the screen and observe how closely it follows your finger or stylus to test the accuracy of the calibration. Now press the “Draw” button to enter the drawing mode:

This is kind of a long process, but it is well worth it if you want to get the LCD touchscreen set up properly. So if you have any trouble setting this up or have anything to say, please leave a comment below. Also, if you found this article useful, please share it with your friends!

The touch screen LCD is ready with 320×480 resolution, 50 FPS (Frame per second). Resistive touch control is being supported by the Raspberry Pi OS or Raspbian (directly-pluggable). However, we will still need to install the driver for graphic display :)

However, there is a dedicated case/enclosure and a low-profile heatsink with a fan for this LCD to fit perfectly on the Raspberry Pi 4 Model B. The case has an opening for the LCD, and the low-profile heatsink with a fan keeps the Raspberry Pi 4 Model B protected and cool! You get a perfect console :) Don"t forget to remove the top lid/cover of the enclosure for the 3.5-inch LCD.

Note: The Raspberry Pi 4 Model B, 3.5-inch Enclosure, and the Low-Profile Heatsink with a fan are NOT INCLUDED in this product, please get them separately.

As we understand, Raspberry Pi 4 Model B delivers great performance and of course, more power will generate more heat as of all CPU :) So we need a way to install an additional heatsink to dissipate the extra heat. It will be better if we can have the option to add a cooling fan for active cooling. Well, this 3.5-inch touch screen LCD comes ready with the heatsink and cooling fan for you to use with the Raspberry Pi 4 Model B. it solves all the concerns.

The 3.5-inch touch screen uses the GPIO on the Raspberry Pi board, so it stretches out 2 pins as the power to supply the cooling fan on the low profile heatsink, and keep the Raspberry Pi board cool!

Note: The Raspberry Pi 4 Model B, 3.5-inch Enclosure, and the Low-Profile Heatsink with a fan are NOT INCLUDED in this product, please get them separately.

The Graphic driver is provided and can be downloaded for Raspberry Pi OS/Raspbian. It also supports Ubuntu and Kali Linux. Do follow the steps here: http://www.lcdwiki.com/MHS-3.5inch_RPi_Display

Note: Please use the recommended system for the touch screen. If another system is used, it may not have the touch function or may not work. You need to configure it yourself. Because there are many systems that the Raspberry Pi can use, we can’t make every system compatible with the touch screen.

Its touchscreen and resistive overlay, as well as its TFT display module, come already assembled, ready to be connected and programmed via your Pi – there is no welding at all, it’s a bona fide plug and play device!

The module uses your Raspberry Pi"s SPI interface, your screen and the SPI (SCK, MOSI, MISO, CE0, CE1) and GPIO 24 and 25 pins. The GPIO 18, 21, 22 and 23 pins are left free, so if you wish you can use them to install four slim tactile switches to increase the number of ways of interacting with your module!

This small, colour touchscreen for Raspberry Pi can be used in many different ways, for example as a console or video screen, a DIY GPS or smartphone screen, or even in a small point-and-shoot camera. It can also be used to create a mini arcade game or a mini computer.

Editors" note, Aug. 14, 2018: Originally published July 2, 2017, this article has since been updated to include new DAKboard features and an open-source alternative to DAKboard, MagicMirror.

For instance, a Raspberry Pi 3 Model B has a higher power requirement (2.5A) and, thus, necessitates a specific power brick. It will definitely still work, but a Raspberry Pi 2 Model B

The ideal board for the job is the £9.30 or AU$14.96) for the board. To set up and connect the Raspberry Pi, you will need a short HDMI cable and a microSD card of at least 8GB.

The most important thing you need is an old monitor -- preferably a slim model with HDMI. Some computer monitors will work better than others. Specifically, those that have the connection ports facing downward instead of straight out from the back work much better.

You will also need an extension cable with at least two plugs at the end. Take note of whether your monitor"s power supply needs a two- or three-pronged plug and buy the appropriate extension cord.

Finally, you will need supplies to mount the Raspberry Pi, the monitor"s power supply, all the cables and the female end of the extension cord on the back of the monitor. I used two-sided mounting tape. And I used duct tape to keep the excess cord attached as tightly to the back of the monitor as possible.

Typically, there isn"t enough room to install a Raspberry Pi inside the original backplate -- unless you"re using a Pi Zero W. Even then, the excess cords and the power supply for the monitor won"t fit. The monitor will sit closer to the wall without the back cover, so it"s best to discard it.

Connect the Raspberry Pi to the HDMI port on the monitor and -- without plugging in the extension cord -- connect the power cables to both the Raspberry Pi and the monitor. Use this to figure out the best layout of all the parts to keep everything as slim as possible.

As for the picture-hanging wire, there were no decent places to connect on the Dell monitor I used, so I drilled one hole on either side of the rear bezel that held the back cover on. This is where you might have to get creative, since no two monitors are the same.

Surprisingly, this project doesn"t require any special code for the Raspberry Pi. In fact, it will be running on Raspbian OS, a Linux distribution specifically for the Raspberry Pi.

DAKboard is the web interface used to display all the information on the monitor. It can be set up from the Raspberry Pi or from a computer, phone or tablet.

Just go to dakboard.com and create an account. Then begin configuring the layout to your liking. There are five different screen configurations to choose from:Top/Bottom

Next, you must configure DAKboard to suit your needs. For instance, start by choosing your time zone, selecting either an analog or a digital clock. Select a date-and-time format.

For background options, you can choose between a host of different sources, such as Instagram, Google Photos, Dropbox, OneDrive, Bing, Flickr, etc. After that, you can connect up to two ICAL calendars for free, select between Yahoo and AccuWeather for the forecast source, add a single RSS feed for rotating headlines, and connect Todoist, Wunderlist or Microsoft To-Do as a task manager to display and add a custom message to the DAKboard.

By upgrading to DAKboard Premium, which starts at $4.95 per month (no specific info about international pricing and availability), you can unlock the ability to add additional calendars, set a Vimeo, YouTube video or website as the background, select

The idea is that, when powered on, the Raspberry Pi will automatically boot to your DAKboard. If you want to hang the monitor vertically instead of horizontally, you will also need to rotate the display.

First, power on the Raspberry Pi, open Terminal and type in sudo raspi-config. Once in the configuration tool:Go to Boot Options > Desktop Autologin Desktop GUI and press Enter.

Next, you will want to edit the config.txt file to rotate the screen 90 degrees. In Terminal, type sudo nano /boot/config.txt and press Enter. This opens the config file in the nano text editor. Add these lines to the end of the file (without the bullet points):# Display orientation. Landscape = 0, Portrait = 1

Finally, to force the screen to stay on and automatically boot with dakboard.com loaded in Chromium, type sudo nano ~/.config/lxsession/LXDE-pi/autostart and press Enter. Inside nano, add these four lines (without the bullet points):@xset s off

Once the Raspberry Pi has fully rebooted, use a connected mouse and keyboard to log in to DAKboard. Click Login and enter your credentials. Your DAKboard should load with your previously configured settings. If you want to change anything, click the settings cog in the upper right corner of the display (move the cursor to make it appear).

Hang the monitor on the wall and you"ll have yourself a digital clock and calendar, the week"s forecast, important headlines and beautiful pictures on display all day.

If you would prefer the monitor to turn on and off at different times to save power, DAKboard includes instructions on how to set that up with a script.

DAKboard is a great way to set up a Raspberry Pi display in a hurry. It"s easy and user-friendly and it looks great. However, it has its limitations and encourages users to upgrade to Premium to unlock the best features.

That"s why MagicMirror is a fantastic alternative for those willing to get their hands dirty and spend a little more time and effort setting it up. MagicMirror is open-source and entirely free. It"s also installed with a single command and you can install modules for clock, calendar, weather, news, alerts and tons of third-party modules that include smart home integrations. You can even make your own modules if you"re so inclined.

After execution, the driver will be installed. The system will automatically restart, and the display screen will rotate 90 degrees to display and touch normally.

( " XXX-show " can be changed to the corresponding driver, and " 90 " can be changed to 0, 90, 180 and 270, respectively representing rotation angles of 0 degrees, 90 degrees, 180 degrees, 270 degrees)
