Next, you need to know the depth. Measure the thickest piece you have. For me, this was the inverter, which was just under 2cm. So my side pieces are 2cm deep.

You also need some way to hold the screen in place and keep it from moving. I didn"t want to attach anything permanent to the screen itself, so I designed 4 small triangle brackets. These should be the full depth of the inside of the case and the screen should be set back just enough so that it is held against the front panel of the case. The last page shows how I where the brackets would be positioned in the final product.

Finally, I made the back panel with a hinge so that I could get into the circuitry if I need to in the future. Just be aware of where the brackets will go if you chose to include this feature and make sure you have room.

You can "create" one for sure but that requires you to develop your own add-on (like the LVDS4Pi or LVDS4Pi EVO) or a full custom board (did it for the CM3L with the board named LVDS4CM3L).

My Dell Studio 1557 laptop died some time back in early 2014. It started conking out a few months earlier, but I managed to “heat-gun” the GPU into submission and it worked for a few more months. My wife had an identical machine, bought at the same time, which lasted a year longer.

The driver board I bought came from Ali Express. It’s no longer available, but I’m sure you could find one if you wanted to. In any case, your LCD will probably be a different part number.

Lots of people throw away dead laptops now, but often the screens are perfectly fine. If you want to bag yourself a gorgeous screen for your Raspberry Pi, DSLR, Video camera or any other computer I’d recommend you give it a shot. Do be aware that you are not guaranteed a result (that’s why I bought one driver board first, then another when I knew it worked).

This is something I did that brought me a lot of pleasure and I regularly use one of these in my workshop as a video monitor and with Raspberry Pi. So I thought I’d share it with the world. If it works out for you, you can really get an awful lot of screen for your money. Certainly more than any screen you can buy new.

Also, be aware that you will have to either sort out your own case or frame for it. For us hacker types that can often be a plus rather than a minus. I just kept the really useful mounting frame on the LCD and hung it from a shelf at the perfect height for my use.

When I first started with DIY audio, I had to use the desk in my garden shed/office for projects. This was never ideal as I frequently work from home for my job at this desk and had to keep packing equipment and components away. After Idiot Child No.2 left home, I moved my electronics to a desk in her old room. Whilst this is a considerable improvement, there is one aspect that is less than satisfactory, and that is a lack of space for my laptop. If I have the laptop out on the desk there is little room for anything else, but I find I often need to refer to material, e.g. datasheets, build information, component suppliers websites and so on, when I’m working on a project. I tried using my tablet but the screen size was a limitation and I prefer using a keyboard and mouse. I started thinking of a way round this and decided a small computer that I could put on my little HiFi rack with a monitor on the wall would be a good solution.

Thinking about my realistic use scenario, I wanted to spend as little as possible on this as I only really need a web browser, spreadsheet for BOMs and pdf viewer. This ruled out the Intel NUC form factor computers as the cost is too high. The recent launch of the Raspberry Pi 4 is timely and this new iteration seems like it should be more than capable. Whilst thespecs are a significant improvement over previous models, there appears to be a slight problem with heat. The provision of a fan appears to mitigate against thermal throttling and for the light use it will be getting, this most likely not an issue for me.

The next consideration was the screen. I didn’t want to buy a new one so started looking at used models on the usual sites until I remembered that I had some old laptops in the shed that I’d rescued from people who were about to dispose of them. I’d managed to construct one complete working laptop using parts from others but still had these lying around in the hope that I’d be able to salvage something else from them in the future. The screen from a Samsung looked quite good so I started searching online to see if I could utilise it. It seems this is quite common and relatively straightforward as long as you can get the screen model number. In essence, you need a way to connect the HDMI out (or other output) from your PC to the particular signal input connector that your screen uses (usually LVDS). You then need to find an LCD controller driver board that will work with your screen, although universal options are also available.

You can buy standalone boards or kits that include various options such as all the cables, inverters if necessary, control keypads, remote controls, cases and so on. I managed to find a kit for my screen on Ebay that cost £17.99 including postage, with outputs for HDMI, DVI, VGA and also audio. It requires a 12V 3A power supply so if you still have the laptop charger (typically 19-20V) you could use a step-down converter. As I didn’t have a spare I had to purchase a 12V 3A AC-DC transformer.

The first thing to do is to find out what is the exact model of your LCD module and what interface it has. Take out the LCD module and check out the back side:

As we know, Raspberry Pi is known as the “Pocket Size PC”, but for debugging and project purposes it’s cumbersome to carry an additional display for it. Also, many of us don’t have access to an HDMI display, so, we figured out a way to easily connect a Raspberry Pi to a laptop display. So sit back and enjoy this simple tutorial!

To connect a Raspberry Pi to a laptop display, you can simply use an Ethernet cable. The Raspberry Pi’s desktop GUI (Graphical User Interface) can be viewed through the laptop display using a 100 Mbps Ethernet connection between the two. There are many software programs available that can establish a connection between a Raspberry Pi and your laptop. We used VNC server software to connect the Pi to our laptop. Installing the VNC server on your Pi allows you to see the Raspberry Pi’s desktop remotely, using the mouse and keyboard as if you were sitting right in front of your Pi. It also means that you can put your Pi anywhere else in your home and still control it. Also, the internet can be shared from your laptop’s WiFi over Ethernet. This also lets you access the internet on the Pi and connect it to your laptop display.

Before moving to connect your Raspberry Pi to your laptop display, you need an SD card with the OS preinstalled, or installRaspbianon a blank SD card. You will find lots of blogs and tutorials on preparing an SD card for the Raspberry Pi. If you are a beginner, you can simply clickand know more about this. This will show how to install the OS for the Raspberry Pi. You can also buy SD cards with theRaspbianandNOOBsoperating systems preinstalled.I would suggest you installthelatestfull Raspbian OS imagefrom the official Raspberry Pi website as it is having VNC Server in the OS package.

After setting up your SD Card, insert it into the Raspberry Pi. Next, connect your power adapter to the Raspberry Pi to power it. Also, connect your Raspberry Pi to the laptop via an Ethernet cable and connect a keyboard and mouse to it.Note:You need screen and a mouse after booting a new OS into Pi for the first time as by default, the SSH and VNC are disabled in Pi. Without SSH disabled, we cannot enable the PuTTY Configuration.

This step explains how you can share your laptop internet with the Raspberry Pi via Ethernet cable. In Windows: To share the internet with multiple users over Ethernet, go toNetwork and Sharing Center.Then click on the WiFi network:

Click on Properties (shown below), then go toSharingand click on“Allow other network users to connect”.Make sure that the networking connection is changed to the connection of the Raspberry Pi. In my case, it isEthernet:

As shown above, the IP assigned to my Pi is192.168.137.144. To check the IP assigned to the connected Ethernet device, do the following. Considering that the IP assigned to your Pi is192.168.137.144and the subnet mask is255.255.255.0:Open the command prompt.

Now, Raspberry is ready to connect using VNC. We just need to install the VNC server on the laptop.Downloadand install it. Now, download theand install it on the laptop.

As you hit enter and all the things are correct, the Raspberry Pi Desktop will load in a new window. You can go into a full-screen mode by clicking on the options available above on the window.

Connecting to your Raspberry Pi remotely with VNC is fine as long as your Pi does not reboot. If it does, then you either have to connect with SSH and restart the VNC Server or arrange for the VNC Server to run automatically after the Raspberry Pi reboots.

Now next time you reboot your Pi, vncserver will start automatically and will seamlessly connect your Raspberry Pi to a laptop display. Good job! Whenever you want to do something with your Pi, just connect it with an Ethernet cable to your laptop and power it. Then open the VNC Viewer, mention the IP address of your Pi, and you can use your laptop’s display as the Raspberry Pi’s monitor.

You can now easily build your Raspberry Pi projects without any need to buy an additional display. There are numerous projects based on RasPi which you can build and assemble on PCB boards for connecting extra peripherals like sensors, power supply, extensions, relays, actuators, etc. You can design your PCB and submit your Gerber files on. They give you instant quotesand provides a wide variety of specifications and additional services.

Laptops don"t last forever, but the screens inside them usually do. Even if the main computer is broken, you can extract the display panel, and reuse it. In today"s project, we"ll be turning an old laptop and a Raspberry Pi into a magic mirror.

Before you start, I should note that counterintuitively, it"s not always cost-effective to try and rescue a panel from a laptop, since you need to find a suitable driver board and power supply. Unlike a ready-made monitor which just plugs into HDMI, the LCD or LED panel inside your laptop will have had a signal directly from the laptop"s motherboard.

In order to use that panel, you need a controller board made by a third party, which converts a standard HDMI signal into one suitable for that display. Annoyingly, the controller board must also be precisely matched to your panel. Once you factor in the additional $30-$40 for extra parts, it may be cheaper just to buy a fully functional old monitor at auction. A cursory glance through the "ending soonest" listings of eBay shows some 17-inch ex-office monitors going for less than $15.

Still want to go on? If you can"t find an iFixit tear down guide for your laptop, just grab a flathead screwdriver or craft knife and begin ripping the screen bezel off. From there, you should able to find the screws that secure the display to the hinges. Take extra care around any existing ribbon cables, as you may need to re-use them later.

Here"s the money shot. The sticker describes the panel and allows you to search for a suitable driver board. Type the model number into eBay (in this case B126XW02) plus "controller".

Expect to pay around $20-$30 for a suitable driver board, the top end being boards with a HDMI connector, the cheaper end being just VGA. If in doubt, take a picture of the label and send it to the seller, most will be happy to advise if you"re buying the right item, or point you in the direction of the correct board if not. You"ll also need a power supply for the driver board: 12v 4a is recommended, which should set you back around $10.

When your board arrives, you won"t find a single controller board: likely you"ll have a separate inverter (for LCDs, which require a high voltage), a board with buttons on for input control, and possibly a remote control receiver board (optional). This is the main controller board:

Since this is an LED, there no need for a separate inverter board. The ports should be obvious, and there"s only a few separate ribbon cable connectors. You"ll find some pins labelled LVDS: this is where the delicate flat cable that connects to the LCD screen will go, but don"t plug that in yet.

The last step was to fit the mirror sheet -- 3mm mirrored plexiglass -- with the screen behind it. It was a tight fit anyway, so no additional fixings were required. I used some double-sided sticky tape to secure the Raspberry Pi and other bits.

At this point, I booted up the Raspberry Pi to find that in the couple of months I"d left this project unfinished in the garage, the screen had been cracked on one side. Half the screen was still functional however, so I slid a piece of black card into the frame too, sandwiched between the display and the plexiglass. It hides the broken area perfectly!

and let it work its magic. If this fails, you"re likely not using a Raspberry Pi 2 or 3. While it"s possible to use a Pi Zero or Zero W, it"s considerably more work.

Your first step should be to configure the default weather module. To make use of the OpenWeatherMap data, you"ll need to sign up for a (free) API key. For our simple needs, the free account is perfectly adequate.

The hardest part of this project was probably building the frame, and I think I could have done better. If I were to repeat the project, I"d likely build a separate front panel with greater depth behind it, and allow space for a back panel to cover up the backlight, which currently bleeds out, as well as hide the cables away. It would also be a good idea to make room for a motion sensor that could turn the display on and off, though the panel itself doesn"t draw that much power.

If this project is not what you"re looking for, or you want something simpler, why not take a look at our guide to Raspberry Pi projects for beginners.
