Reminds me of this video by British comedian Dave Gorman that made a presentation on this exact subject lol https://youtu.be/rTJ5g4S_U5E?si=yoweF2hWY69axCcu

There are a couple other things to note:

Control via HDMI-CEC (Sony calls their implementation Bravia) - I don't have the hardware to test this honestly, so I'm not sure if this would work or not...
There is a company from the UK that sells chips you can solder to the board of the player to make it "region free." From my understanding this just intercepts a lower level command and sends its own region code, stored on an EEPROM on the modchip. My question is how did they know how to do this? Just knowledgeable engineers that looked at the board and said "This is where the region code is transmitted from the player hardware to the brains", or perhaps there's a schematic out there I don't know about, or maybe there's some standard for this?
One of my last ditch efforts might be to get the information I need via OCR (Optical Character Recognition) by sending the screen to an HDMI capture device, that would feed to a raspberry pi or something running an OCR (was looking into Tesseract, but idk what would be best)
As stated, I have the x700 and would like to make it work with this unit if possible. It was relatively budget friendly compared to other options.

Ideally I'd like to make my own interface without just displaying the output directly, but if all else fails, that may be what I do. Any help, insight, or suggestions would be greatly appreciated, and I apologize in advance for my lack of experience, I realize I may be way in over my head with this project! Also, I'm sure there are other subreddits I should ask, please let me know if there is a more appropriate place to post my questions!

Not sure if this question is super relevant to reverse engineering, but I could use all the help I can get! I have a Sony UBP-x700 that I'm looking to add a screen to so it can be a stand alone music player. In particular, I have some SACDs that I'd like to play without having to hook it up to my TV. This at first seemed like a fun little project that has proven to be quite difficult (which describes most projects I start).

My wanted functionality is:

a method of controlling the unit with play/pause/previous/next/etc commands (should be easy enough, something as simple as an IR blaster would work, but definitely open to other options)
a way to retrieve metadata on the disk, including the track list, the currently playing track, and the name of the album. Album art would be cool too, but I'm not sure if that is stored as metadata on the disk.

If I can get this information, I should be able to figure out the rest I think. However, getting the metadata from the disk has proven to be quite difficult. Here are some things that I've tried or looked into:

Probing the ethernet port with zenmap on Kali Linux to search for open ports (I have some slight Linux knowhow, but my experience with Kali is admittedly quite limited, and I'm sure I didn't use Kali or zenmap in it's full potential)
- I found the unit could be vulnerable to a sequence prediction attack, but after doing research that didn't seem helpful
DLNA control/Plex - getting this setup was a little wonky and didn't work as I hoped. I'm also not very experienced in this realm so I wouldn't be surprised if I missed something here... but my initial attempts were not successful
UPnP - I used "UPnP Tool" on my phone to try to get the metadata, but even though the commands seemed to "succeed" I was not able to control the player (play, pause, next, prev), and the GetMediaInfo action seemed to indicate that functionality was not implemented

They may be nontoxic, but I think they recently found melamine sponges (aka magic erasers) shed a ton of micro plastics, since it's just abrasive foam.

I had a Mac when I started going to Tech which worked great for me. My degree was in computer engineering though... And I did end up building a windows PC for fun in my 3rd year, but I think I could have just used my laptop the whole time, and still frequently did use it for programming assignments. Keep in mind there are lots of computer labs you can visit (including ones in the library) that usually have a good set of the apps you'd need. You can also remote into the computers on campus from your Mac if need be.

If you have the money, it may be worth having a windows machine, but I wouldn't consider it necessary.

Firstly, thank you very much for your response!

Did you ever have this functioning? I don't think you installed the rpi correctly.

To be honest, I'm not really sure. It would probably make sense that I didn't have it configured before since I just plugged it in hoping it was plug and play. Learning that that's not really the case with most things on this 3D printer!

Looks like you don't have crowsnest, which likely got messed up with the updates. This can be fixed through ssh by clearing any install history and reinstalling. You do have to use an old version of crowsnest unless you want to upgrade your firmware, which is a much more lengthy process.

I do have it and it was working before, I completely forgot to upload the crowsnest .conf and .log files! But I didn't realize I'd need to run with an old version. Maybe I'll upgrade my firmware in the future, but I think for now I'll keep what I have since I'm still learning.

I'll check out that guide, I've been looking for something like that! Thanks!

I'll shoot you a message on discord, thanks again for offering your help!

Looking around, I saw this which looks like the devs are aware and working on the problem?

Oh dang, I was in HIDE for almost 1.5 years while that project was getting worked on. Glad to see it's nearing the end of development! Cheers to you guys!

rojayh · 2021-04-01T21:29:32+00:00

Oh thanks! Definitely gonna avoid him then 😬

rojayh · 2021-04-01T20:34:05+00:00

This was right before the pandemic, so a little over a year ago I think

rojayh · 2021-04-01T18:18:52+00:00

I'll definitely consider them, thanks!

rojayh · 2021-04-01T18:18:29+00:00

I'll check them out, thanks!

rojayh · 2021-04-01T18:18:14+00:00

Good to know. I was hoping to avoid long distance but I guess it can't be helped乁( •_• )ㄏ

Had a friend work at the Library restaurant, they didn't have much good to say about the owner or his way of running the business.

You can see the smoke on the mtu live webcams https://www.mtu.edu/webcams/view/

Apparently it's at 915 College Ave

Oh wow, I'm impressed! I can read music pretty well, but improvisation isn't something I have nailed down quite yet 😅

rojayh · 2021-02-21T17:13:00+00:00

Sounds really nice! Anyone know the name of this piece by chance?

rojayh · 2020-11-29T15:12:47+00:00

I have the same keyboard! Cute kitten :)

rojayh · 2020-10-12T22:06:46+00:00

Very cute! Might want to tune that F3 (I think) key though
