I have a Raspberry Pi Server and Want to conntect the display of an old laptop and a keyboard directly to the pi for offline controll. Is there also an adapter to use the keyboard of a laptop in usb?
@@seeking9145 sorry, not sure!
URL doesn’t work anymore on TH-cam shorts
the problem is the broken part of laptop is usually the screen itself
That is true - in my case I knew the monitor still worked because the liquid was spilled on the keyboard and inside.
Not always. With mine, I'm almost certain it's the video flex cable, which goes bad on many models due to friction depending on how they fasten the lid to the unit. Also the display inverter can go bad, but I've heard those tend to be more durable than the cables, provided they aren't exposed to frequent excess heat.
Laptops now though? With the typical build quality, it's usually the chassis itself or the hinge area that sets off a domino effect of destruction.
Did you know...if you sold that laptop display you can buy used pc monitor and even have some money left..decent ones go for about the 1/2 price you paid for the board you used and they come assembled.
Got me at "Did you know" 🤣 Are you saying that a decent pc monitor goes for $15?? Where do you find those? The board was only $30 - plus it was a fun project to do.
@@techfulgoodies I just had to say it😂 glad i got your attention🤣 Well, "decent" is a broad and subjective term, but since we are not talking premium display quality here becose we are reusing few years old laptop screen, and i don't know about the US, but here in Bosnia, yes, working used few years old 15-19 inch pc monitor can be bought for about 15-20$ at local relcyclers. Checked just now, Acer 19" wide screen was 18.5$. Used laptop screens in good condition are way more expensive and easily sold to repair shops for about 30-40$, plus if you want to use them as a external monitor you also need to build a case, wich is time consuming and probably gonna cost another 10-15$ at least. I have few dead laptops around the house and was looking to reuse screens as you did, but i didn't becose..well..math😀. But.. reusing laptop screens like that can be great thing if you need a monitor for a project to fit in certan dimensions and pc monitors don't come in that size, or they need 12v low power consuption monitor with hdmi input etc etc becose those can be very expensive. As a fellow tinkerer ,"Fun to do project" is a whole another matter, you can't put a price on that, i no way but "it's fun" i could justify putting 100s of $ in 30 year old Amiga🤣

@@aleksandarl6975 Ahh, the international difference - here in the states, monitors can be found a second hand stores and buy buying from other people but sometimes you get stuck with VGA or DVI and I wanted HDMI but your point is spot on. If you want to build this type of thing, you do have to deal with the home made results 🤣 Thanks for the sub! Look forward to seeing you around in the comments!
@@techfulgoodies You're welcome, it is the least i could do for felow tinkerer, i'm looking forward seeing more "hands on" content from you.
@@aleksandarl6975 ✋🤚🤣🤣
Scaler device is always more expensive then old monitor of corresponding resolution. Monitor below 4K costs $30 and a scaler for it costs $25, you also need a PSU for both. And 4K scaler is a rare item >€100 and the refreshment rate is not guaranteed.
Ironically I'm typing on that very laptop right now - the panel on these is a TN panel and the cost of the daughterboard makes it far from cost effective for anything but niche uses such as a custom installation or something.
If the system itself is still functional - it's got quite a useful life as a slave/workhorse machine. I had parts left over to assemble a Thinkpad T420 with no keyboard or screen, I use wake-on-lan (it's in a docking station) and use its Debian 11 installation to perform recompression, checksum production, etc. even on other machines. I can send it to standby, wake it with a WoL header packet. Even when it's on the power draw is minimal, it's useful well beyond the effort to get it going.
I would agree, this is more for people looking for a fun thing to do with a completely busted machine. You have more skill than I do when it comes to re-using the internals but also my laptop was used and abused by my young kids so it was DEAD. I use the monitor for an external camera hdmi monitor so I can see while filming so it works fine for $30
Definitely a good idea for a budget arcade build
Me after seeing this video:*stare at my old laptop and a new laptop*
What’s the name of the device
I'm also going to buy a controller board for my old laptop screen, i wonder what charger do you use for the controller board?
When you find the specific controller board for your monitor panel, it will say in the description what power solution you should use, i.e. 5v, 4v, 3v etc.
Should also grab a board like a Framework board and attach it. Maing a m9niter that has the computer built in. Kinda like what Apple did but better because of the satisfaction that you built it.
Diy perks also did this
I did this a while back but my screen keeps saying there is no signal. I can't find a solution for this problem anywhere
Is it possible to use also the keyboard of the laptop via usb with an adapter?
I'm pretty sure you can although I have not done it. I've seen many videos on TH-cam where people take a laptop and make a stand alone PC with it - perhaps check for some of those videos?
Cool. Is there a case for the device so it looks presentable? Or help with cable management?
I haven't done anything with that yet. Best bet would be to 3d print something because I don't think there would be any standard case you can buy.
scotch it behind the screen and make a tower of toilet paper cardboard and stick the screen on, paint it in color if you want
Are LED / LCD laptop monitor cable connectors universal? And what about monitor power rating, voltage, amperage, etc?
I've been looking into getting a screen replacement for my now rather ancient HP Pavilion dv4-12xx (I know I REALLY shouldn't invest in it, but it was the first and only computer I've bought at retail), but noticed there are several different screen options even per model. Still can't figure out which one is best or which ones are compatible with my particular model.
I want to replace the motherboard too to switch it from AMD to Intel, for an ever so slightly better CPU and GPU... But the only place I've found selling it as a complete mobo combo package hasn't replied and worried the company might be defunct now. Pinnacle Tech I think? If anyone has any info on them.
No they are not universal. If you look on the back of the monitor there is a model number (for me it was LTN140KT07) and that is the specific panel that I needed to buy an adapter for. You would potentially have to take out the old monitor to find out exactly what panel you need. Sorry, no info on mobo combos.
whats the device you say i have to connect it to
We did this couple months ago with my dad. It ignited...
🙀
Well... It did give you something to look at at least 😂
I’m pretty sure those ports are outputs not in. The lvds from the screen is the only input
So there is HDMI, DVI and VGA that should all be display in, the sound would be "sound in" if there were speakers attached and the power would be power in, right? Video comes out of the computer and into the monitor. Or are you saying it is meant to daisy chain somehow?
@@techfulgoodies I’m an idiot, your right. It’s backward from normal. Can you get that for any screen? I assume you have to know what connector you need for the output since there’s a bunch of different ones.
@@twitch54304 I'll let you in on a secret, I convinced myself that I said it wrong multiple time while either editing or watching the video so you're not alone! Always keep the questions coming in!!
@@twitch54304 Oh and yeah, from what I understand, you should be able to get them for most every screen - just match up that code on the back.
@@techfulgoodies Thank you! I’m going to have to check that out
How abou the power for LED backlight?
You have to provide a 3v or 4v power supply based on the board. Full video here: th-cam.com/video/WCWD4wzmpDU/w-d-xo.html
what is the name of the adapter Again?
For me, after connecting the controller, it flashes constantly on and off :(
What is that device called?, the one used for connection and I wanted to know that does it work for any screen? Or do I need to buy control board?

How to make my sony non smart tv into computer display without hdmi??
Now make a video explaining how to make the controller because here in my country it's hella expensive.
So without controls then it’s just brightness = 💯?
No, the adapter has the same buttons and menu just like a normal monitor so you can adjust all the stuff. Check my channel for the full step by step video
So nobody knows what the device his using is?
Thankful ❤

Is it possible for microsoft 4 pro screen.? Coz my laptop is dead and screen is good
what do you call that external connector?
What is that small thing called??
I've yet to see someone do it with a MacBook Pro. That'd be a great external display.
Very true, I've been considering trying it with an old iPad that I have but don't have the heart to gut it yet.
Whats the name of the board
That laptop is just like mine
How about a tablet LCD, can we also turn it ext monitor like this?
Good question,I have a few tablet lcd at home
can we use the old macbook screen as a monitor? 🧐
Yes, that should work just fine.
@@techfulgoodies cool, but I'm worried the screen won't work as well as the direct connection to the motherboard of Macbook, or maybe the color is wrong or it's not retina standard anymore
@@tuphan95 The controller board is made specifically for your display model number and should have all the features that your monitor has. You can check out the full video here: th-cam.com/video/WCWD4wzmpDU/w-d-xo.html
How to buy extra device
Any idea if you can do this with an old garmin gps?
Sir can you tell me which panel used in this Led serial number LP140WH4 (TL)(N1) which board i can buy
If you search on Amazon or on Ebay for the model number and the TL N1 you should find them. I found this one but I cannot guarantee it will work. www.amazon.com/LP140WH4-1366768-HDMI-Compatible-Screen-Control/dp/B097L7YSL4
@@techfulgoodies thank you for your response sir but this item is not delivered in India yet
Can it be done with even older, smaller, crappy laptops?
Should work with anything that has a flat LED panel. Just may be difficult to find the adapter for your specific panel.
What’s the name of the adapter you used?
I put a link in the description. They don't have brand names, they are custom boards for the display panel. Look up the LTN number for your specific panel and you should find it.
What if that doesn't help? Or if you can't find that number?
What's the general rule for #of pins, display type(OLED,vs LCD etc) and general specifications?
@@petevenuti7355 My full video shows you where to find the number: th-cam.com/video/WCWD4wzmpDU/w-d-xo.html but if you don't find one, then you wouldn't be able to get a controller board for it but almost all panels should have it. As far as the pins/display type, etc. you would have to ask the maker of the board.
How do i know which type of adapters do my screen needs?

Does it have sound
My monitor does not have built in speakers so no sound for me.
Device buy link pls
What brand or code is put on a remote control?

Cost of parts?
The controller board was about $24 and the DC plug was $4

Only laptop monitors?
No, actually most display devices can be converted, even tablets and ipads
Well here I am typing on a Chromebook display using this thing!
Awesome! Love it!
@@techfulgoodies did you use a latitude E6220?
@@user-brokeandroid Close, E6430 is what I used.
Stare i już dawno zapomniane... 😂

yeah but the board is worth more than the display
Is there such a board for a touch screen?
I believe there is. I’ve seen them for iPad screens but I haven’t tested them yet.

No need to buy a gaming monitor
The $30 parts make no sense for this project. A used portable monitor (1080) at eBay only $40.
Some people like doing DIY projects just for fun - but if you have not technical skill I guess it makes no sense
Or buy a few year old used 21" monitor from a crackhead on Facebook marketplace for $30
😂😂
