Hi all,

I made some investigations about the temperature of my PI…

without any cooling - around 52 degrees Celsius with a heatsink from an old PC stuck with cable ties - around 42 degrees Celsius with heatsink and a fan, also from my old PC - around 30 degrees Celsius

May be this is interesting for someone who use a PI in a close frame.

@rikko14 said in which monitor to choose ?:

which monitor to choose?
a PC screen or a TV?

Well you want a display screen and confuse which screen I buy Tv or Pc monitor. The choice is yours but I can help you to take a decision.
Usually monitors have higher refresh rate, faster response time then TV and low input lag. On the other side TVs have large screen and they are fantastic for watching movies and playing games. TVs are less expansive than monitors.

Hi, I saw your post and I m exactly in the same position.
I already bought a 24” touch foil. I tested with a transparent glass and it s working 100%. But when I put above the two way mirror glass…the touch foil doesn t work.
Can you please tell me what kind of glass do I have to use? I need to buil an oval magic mirror.

Thanks
Andrei

@madscientist io games said in What controller board do i need?:

@besiece Your panel uses an eDP interface. You can find universal eDP controller boards with the usual suspects, such as Aliexpress or Ebay. I don’t know how the touch interface is controlled. The datasheet for that panel doesn’t mention touch at all. If it is via a second 4- or 5-pin connector it’s possibly USB.

I have not yet dealt with eDP displays. My experience is with LVDS panels only.

Thank you so much! It’s very helpful!

Hello EoF,

I am trying to build a two way mirror that’ll work with touch screen. Were you able to find any non-metallic mirror films? I have been looking but can’t find any?
Would appreciate any guidance. Thanks 🙂

@mann “Does the PI 4 support turning USB power off and on in software at all? If it does, how to do it?” : I don’t understand what you are telling me, so what should I do?

Hi! I’m building a smart mirror, and got the below specs from a local glass shop. Does anyone know if that glass will be suitable for a smart mirror, or is there anything that could be better? Will this be too dark or too light? Thanks in advance!

Cross post from Reddit sorry.

Hi, Did a quick search, didn’t find a related post. I have a old HP all in one PC that is also a touchscreen. The screen has no external inputs but was thinking I could somehow directly interface the video and touchscreen with a pie. Is this a viable solution? Appreciate any info links or posts I missed. Love the project!

Cracked the case open. Some txt on the back of the panel.

Took apart a VN247H monitor from ASUS, and to my surprise the LCD driver was actually thin enough to fit inside the picture frame I got. Nice. However, the 230v circuit board is NOT that thin, because it has a few large capacitors and a large heatsink.

I got about 18mm of clearance, so I need to be able to power the monitor within those limits. How do I do that? I was hoping externally powering it would be an option, but I see how that’s a problem, as I guess it takes a lot of voltage to power the backlight. Here is a picture of the 9 pins going into the LCD driver, and here is a picture of the LCD driver.

Should I just get a new LCD driver and power supply combo? If so, which one should I pick? The monitor is 1920x1080.

@billycarlson what is a skywriter?

Hello everyone,

after using the search function and reading through different posts, I was not able to find any useful information.

I happen to have an old Dell XPS 9343 with a QHD display (3200x1800), which I would like to reuse. I was able to disassemble the notebook just fine, but have hit a snag:

The LCD is glues to the body, of the lid.

So I do wonder if I really have to remove it, given that Dell seems to be using a 40 pin eDP connector. Is there a way to use that one, instead of having to open up everything?
The screen supports touch, but I don’t really care nor need it. So just getting the display running would be great.

Also it, seems that the driver boards will usually just support FHD resolutions and do not go beyond that resolution?

Any pointers as to what I could to to be able to recycle that display would be much appreciated.

@farhad said in Unsure of which LCD controller board to buy:

SU6C12H10AS01X

Can you post pictures from the backside of the LCD panel. Make sure all labels are readable.
If I google for SU6C12H10AS01X I only get info about the Toughbook, nothing about the LCD panel.

@joern this sounds like a corrupt SD card.

the memory technology is write once. when writing again the prior bits are marked as used.
problem, the file system does not know, and there is no signal of full…

so then it ‘thinks’ it wrote out data but it didn’t.
the only fix is a new card. maybe you can read some older stuff off.

@sdetweil
indeed, I thought about a take out of the backsite of the frame, too. Or two layers of frame with a slimmer one on behind the first layer. So that the mirror cannot fall out tonthe front.
The lips have the same function and thats a good idea.

Have to build a new frame, because the current/old one is exactly sized for the 24".

Regards.

@laurafox08 yes, those should be fine. no real cpu hogs there. still shorter on memory, so make a bigger swap file

like pi3.
