$20 mini-dvd player LCD hacking


[Jeff] sent in this nice how-to on gutting the 2.5″ LCD from a $20 mini dvd player. After removing the player hardware, he shows where you’ll need to tap the circuit to feed it composite video. Looks like just the thing for those portable console projects.

    This is a straightforward, economical, and practical hardware hack. Well done.

    This hack looks really sweet. I’m going to have to do it. just because it’s cool. A question I have is that chip that you pried up, were you able to get the datasheet for it? I’m thinking about trying it myself but seeing if I can make switches for the Audio/Video IN vs the DVD player. It’s going to be some tiny switches, but I’ve got $20 to blow in case I screw it up.. :P

    If I complete the hack, can I reference your website?

    Any idea what LCD controller is being used or what the pinout on the LCD side is?

    I’ve just ordered two units. Will report if I can figure it out.

  4. I have 4 mini composite ready LCDs laying around and no idea what to do with them… I really don’t care about making stuff portable anyone have any idea what I could do with them?

  5. what is the resolution of the lcd? anything decent?
    sounds like the perfect thing for a mini lcd projector

    any response appreciated.

  6. @twistedsymphony – Get one of those NES Connect to TV Controller things. Tear that apart and you have a fancy Gameboy.

    Also can you recover the Laser Diode for a neat (if not powerful) laser pointer?

    Those are some pretty terrible pictures, but it is fairly straight forward. Seems a waste to toss the whole thing just for the LCD though. Anyone know if the discs it plays are real DVDs (just on 1.4 GB discs) or some proprietary format?

    The first thing I thought of looking at the screen and case was to combine it with the C64 on a chip Radio Shack sells…

    Just the other day I was hooking a couple of those little TV games through our portable DVD player.

    Even if the DVD part has failed, it still means there are a ton of potential composite video monitors/amplified speakers out there with their own rechargeable batteries attached!!
    Hacking wise it’s very cool for folks using video cameras and transmitters, although many of these things probably aren’t that great for gaming based on size/resolution.

    Not sure I could think of what to do with this. If I want to play a movie on the go, I can either burn it to a mini-DVD or rip it so it plays on my PSP. If I want to play a game, I have a PSP or a DS. If I want to play a console on the go, I need a power supply for the console, and a 2.5″ screen would mean I’d have to somehow get the unit within a foot or two of my eyes while using both hands to hold the controller. And maybe there are a bunch of project kits that let you output composite video from an embedded system, but I’m not familiar with any of them…

    Still, it’s a clever hack, and I’m glad it got posted. I guess inspiration could strike somebody for a really useful thing to do with this.

    Hey! Here’s one: have a composite output from your video card that you’re not using, and you’re running Vista? Maybe you can run Sideshow on this monitor? I don’t know, but it would be worth investigating.

  11. Eyuras says:

    Hmm, mini photo frame anyone?
    Just needs a frame and then link the composite to your camera and that would be a nice gift for someone!

  12. Jeff Ledger says:

    Here’s the forum thread (Parallax Propeller Forum) where this all started.. A lot of information is there.

  13. BigD145 says:

    This would make for a cheap carputer install if you add in a trackball.

  14. srilyk says:

    If you were able to provide the power, etc. in a smaller form factor, put in an SD card reader, this does have the making for a sweet pocket photo album.

    My other thought – this has potential for use in a HUD system for your car…

    /me may have to mirror for personal use…

  15. Jeff Ledger says:

    Actually this is only step one of this project. I’ll be dropping in a Parallax Propeller with an SD adapter to create a portable microcomputer out of this.

  16. tom61 says:

    MS3FGX, I thought Radio Shack long ago stopped selling “C64 on a chip” systems. Is there yet another one they sell, or the actual chip available by itself now?

  17. Orv says:

    It’s probably an infrared diode, so it wouldn’t make much of a pointer. At least, not for humans. ;)

  18. Auken says:

    Does the DVD player itself run a slideshow of JPEGs? that would make photoframe projects as simple as making a frame case for it.

  19. Mycroft says:

    @twistedsymphony

    If you can separate the mini-comopsite monitors from their backlights and cases, you could try your hand at making small projectors.

    I would suggest checking http://www.lumenlab.com/forums/index.php out. It’s the major DIY projector forum out there and will have most of the information on how to design and build projectors cheaply. If you want to garner a little fame for yourself, figure out how to make a good projector using those annoying while automotive “projector” headlamps. The ballasts should be drivable from a PC power supply. Make a couple little projectors, take pictures, put google ads on your website, and submit it here! Oh, yeah. Step 4. PROFIT!!!

    lovin the Propeller…

    @15, 17:

    The diode is usually invisible to humans; I’m thinking it’s ultraviolet, but I could be wrong. I believe it could be dangerous if shined in someone’s eyes (unlike your typical red pointer).

  22. guzziman says:

    Skyler…ANY laser is potentially damaging to the eyes if shined directly in…even the red ones. NEVER shine a laser into someones eyes. The diode is infrared, not ultraviolet.

  23. Jay says:

    Running dual lcd’s with channels for side-by-side broadcast from a stereopair camera system would be sweet. DIY cheapo hmd, with the right chipset you could add ntsc3d switch for dvd play. Or hack it up from ipod nano lcds. Using the right optics of course, for either.

    ms3fgx asked in comment #6 about whether the mini-DVDs the CyberHome player were standard DVD format? Yes, they are. I got one of the units to try the hack explained here, but before I could even start, I fell in love with the unit, as-is. In fact, I’ve been making some music video mini-DVD-Rs using Nero Express, and they work great! I think I’ll have to get another unit to hack! :-)

  25. Tommy says:

    I wonder if the TV Wristwatch has composit outputs. Its small enough to install in the mini-dvd case, and then you could watch tv on this unit… Anyone know of any small tv tuner chips?

  26. GARY says:

    I have a old toshiba satellite that I;d like to hack to do something like this, has CD drive, could this be done to it to hack into PS1 portable or video player?

  27. Cars says:

    Great Deal!! Good Information.

  28. sq says:

    just did something similar myself. I’m going to look on ebay for one of these as well though. Looking for another viewing location in the house.
