It has an NTSC tuner. Therefore wouldn't it at least accept Propeller video in broadcast mode?

If is shouldn't have an AV input, the RF tuner is always a separate part and can easily be short curcuited

OldBit,

Yes I did get one and open it up. It doesn't expose an a/v port anywhere.

I have to go, but will post some pics of the guts latter.

The Lid has a 30Pin connector·to the base that contains the DVD motor, reader and power circuitry.
The top has 11 buttons, 2 speakers, and the Screen.
There is a head phones outlet, but know video!
It sure is a vivid screen though. If someone ever hacks it, please let me know!

I've been searching for a pin out to the encoder chip, but no luck so far. SharpRB5P006AM.
From what I've read so far, It takes a baseband signal. If I only knew which leg to hi-jack the rest would be gravy train!

bambino

Rayman, It is a scary thought, I know! This weekend I hopefully will have a chance to probe some of the lines and see which way they programmed it. Since the sales sheet for the DVD player mentioned NTSC, I am hopeing that they indeed did use that protocal.
FYI, There's a third alternative programming possible, Y/C.

OldBit,
I checked the Voltage on the switch pin, according to the data sheet page 10 It's in NTSC or Y/C mode, not RGB.
I can not However find where the composite in pin is linked to. It doesn't come straight out to the 30 pin connector.


Just a thought, Maybe we should drag this thread off into the sand box? What do you think?

Oldbitcollector (Jeff)
02-02-2008, 08:58 AM
That's actually a piece of good news as far as I'm concerned. The existing drivers should work with it.
Since this monitor can really only be used on the Propeller as opposed to STAMP, or SX, this seems a
reasonable place for the discussion, but that's up to the powers that be... :)

Ok then, Found the Vin input capacitor("labled C91 next to the 30 pin connector").
My Eye balls are burning pretty good by now, but I've locatated 8 pins that interface to it on the 30 pin connector.
From the picture orientation above there right to left, approximately at pin 5, 10, 15, 17, 19, 20, 21, 25. Like I said, it's late and last time thru I counted a 32 pin connector so I'm definately calling it a day!

If this works, all the controls can be accessed via spi interface. Tint, backlight, contrast, ho,ho.
Going to need to lay off of the coffe for a while before attacking that hirose cable too!

I just went back thru to record which pins are ground and found the exact pins running to c91.
Can the signal be feed into ground? which side of c91 where you using!

Mike Cook
02-04-2008, 12:57 AM
See attached photo, pumped video signal in on C91, far end from the 30 pin connector, then used one of the round plate through holes on left side of the 30 pin connector for ground.

Have not done much with it since, too many 'honey doos'!

Sorry about that OldBit!
Thanks Mike, I guess I haven't found where the signal is coming from yet, back to the magnifying glass.
The signal from the DVD has to come thru that connector from the bottom some how, any chance it's using the y/c protocal to get it there. any way thanks for the pic. Noticed also, the unused, exposed pad next to c91 is also ground!

Either way, if we can figure what lines the screen needs from the bottom to stay alive, (power, ground, signal), then I can start removeing the circuit board from the bottom to make room for some payload.

OBC, I know this is only very loosely related but you might also be interested in this....

www.dealextreme.com/products.dx/category.606 (http://www.dealextreme.com/products.dx/category.606) 'The OneStation' only $30

When I have completed my current projects I am going to have a go at connecting it to the prop.

It lends itself to a portable Hybrid/Hydra type console......

It's very hackable and of course it's 3V which is even better

My idea is to produce a cartridge with a prop, eeprom and micro sd card slot on there.

Datasheet here www.propgfx.co.uk/OS/TD025THEA3_Product_SPEC_0809.pdf (http://www.propgfx.co.uk/OS/TD025THEA3_Product_SPEC_0809.pdf)

Still no luck finding the signal on the 30 pin Connector.

Here is the voltages I found on the Cable while powered up, not connected, and no DVD present.

Note: cable is upside down.

Also first 7 lines on left side are Button matrix lines

Oldbitcollector (Jeff)
02-06-2008, 06:29 AM
Ok,


Getting close..

If I (doing something I shouldn't) put the video signal on the top of the resistor
given in Mike's diagram, and short the screen for a second causing a reboot
of the LCD, I get a very nice NTSC image for about a second. (in full color)
When the chip reboots, it sends an additional video signal to the screen
causing it to look much like the screen before. In my case, the graphics demo
goes from color to b/w with a hint of the blue post screen behind it.

If we can find the signal pin from the chip and kill it we should have a working
screen.

I think I'm going to go backwards and see if I can find the signal with my
monitor.

The more I look at this, the more it looks like an "nano" (cut-down) protoboard would
fit just fine inside the dvd door. Time to start looking over those button controls in the monitor side. The battery is 3.6v, which should be fine for running the propeller chip, drop in the nano, connect the video/audio lines, create a plug for the pda keyboard and you'll be all set.

OBC,

Have you checked for how many char/line and lines you can fit on that screen? Looks to be around 40 char/line by 12 lines or so.

Don't know how readable it is; when I enlarged view it wasn't very clear. What is the char size in pixels (height by width)?

Since I have one of those keypads, I can sense that player LCD is quite small. Good job at hacking the unit. Thanks for the view.

I'm using the 'standard' TV_TEXT object as delivered with the Propeller Tool. I've got a little 'video noise' on my display, but I believe this is due to the non-shielded hook-up wire that I'm currently using. Otherwise the display is crystal clear. @40 x 13 the text is tiny but readable.

I wonder how long the battery would last playing an actual mini-dvd movie... All the new portable dvd players seem to advertize their play time. But, not a word in the write up for this thing...
I think I could DVDShrink a video down to the resolution of this monitor with no noticable quality loss and fit onto a mini-dvd. But, I bet the battery wouldn't last for 2 hours...

I'm torn now. I don't know if I should order me a TQFP to put in mine (OOh the waiting on UPS!) or just use my spin stamp(No waiting)
I already have a board cut and mounted to the sockets where the motor assembly was.

Well I forgot and left mine on the other night. With the DVD chip removed and the Propeller Proto Board running off a seperate supply the screen ran for about 12 hours. I didn't totaly discharge the battery so it can probably go a bit longer than that.

By hooking to the data pin found on the back of the LCD board, I strongly suspect the only requirements left are power and ground. I'm heading this direction..

Was looking at your 'dreaming_maybenot' picture and realized how small the unit is. The keypad measures about 3.8" Yeah, pretty small monitor screen for my ol' eyes.

And what is 'hackday'? I googled but it took me to some strange place. Maybe the URL is more complex that what I imagine.

Little off topic,

There is a very tiny 3v motor that moves the optics. Decent power too.
It's the one connected to the red/white leds. (so cut them near the board)
These might be interesting for bots later.. :)

That is a very interesting idea (chopping up the proto board)! Does the existing board really run at 3.6 V? I assumed there was a voltage regulator to 3.3V in there somewhere...

bambino
02-08-2008, 08:28 AM
Look at the pic of the hirose connector. There is a 3.3 and a 5V line. No idea what there running or how much juice can be pulled off of them.

bambino

The idea of using a spin stamp is starting to worry me. Would 3.6 be enough to keep its regulator happy, and for how long?

5v.. Where are they getting 5v from? Might be enough to support a PS2 keyboard jack somewhere.

Found it also at capacitor BC11 just behind the DVD Data connector. Between it and the battery connector.
If it's running the Backlight or the top side amp it could be risky hooking up to it.

bambino
02-08-2008, 09:29 AM
OldBit, Datasheet says 3.6 OK. Absolute maximum of 4.0V.
So what do you think about the regulator on the spin stamp, would 3.6 volts be enough to run it.
I guess a better question would be does anybody know where I could find the datasheet for the reg on the spinstamp?

Jimmy W.
02-08-2008, 04:22 PM
@bambino the best 3.3v LDO regulator I know of still needs 4 volts, he is talking about running the prop straight off the 3.6v, which SHOULD be happy, waiting on my pcb to come in the mail
Will have video, audio, SD, and interface the buttons, pics to follow


Jimmy

EDIT:
Also seriously considering adding an av input somewhere with a voltage detector to switch input over, would be quite handy at times.
Sigh, looks like I will have to order another PCB, only thing I didn't think of that I really want.

Has anyone opened the half of the case containing the screen and taken pictures? How thick is that part of the case, anyway? I'm wondering how much room there is in there for something like a bluetooth or xbee board.

I've got a couple on order that should arive in the next few days. I'd like to use the keys built into the screen half and maybe put some other electronics up there (inspired by a lot of the EEE PC hacks, I guess).

Oldbitcollector (Jeff)
02-11-2008, 02:46 AM
There isn't much room for additional parts. If you sacrificed one of the speakers, maybe, but it's a pretty thin (width wise) area.

I've got hopes of getting buttons working myself. I think it should be doable from the connection on the bottom board.

OK, I'm back, but I have a problem. I didn't take a picture of the pads before I soldiered and Like you said It's hard to see thru the nail hardener. Can anyone post a pic of the pads and I'll try and label them!

bambino
02-11-2008, 09:06 AM
Due to the lack of a picture and the fact that I can't remember exactly where they all where here is a shot of the pin connector on the bottom.

I used it with a continuity checker to locate the pad and then soldier!
As far a cross shorting goes, Im hopeing the nail hardener will provide some insulation.

Then thing I wanted you to verify is the signal pad, which I think you can see clear enough. I get continuity with the signal pin marked on the bottom30Pin shot as well as the pin to its left. If you can check this out on yours it would be a big help. Right now I'm afraid to power up and check anything!
I did have a short, got lucky, it still runs! I had to take off every wire to find it though. I think I'll just use the wires from the connector next time.

@Mike
I've not done it, but if I where going to try I would start by applying plenty of ground and appling power to the 5V and 3.3V lines.
Some of the 2.5 V lines might be needed but I suspect they are feedback lines from the Driver.

Mike:· It looks to me like the video signal goes straight from where we are connecting to the LCD cable.· The LCD controller is on the card behind the LCD.· So I think the panel part will work by itself.· I think I'll try that with my second unit...

PS:· This area where we connect the video signal looks like twin LCR filters (one is C41,R61, L5, C40, C42 and the other is C45, R65, L6, C44, C46).· I think we could just remove L5 instead of removing the big chip...

I wonder what the second LCR filter is for...· Maybe there are two video signals going to the panel?·

Yes, Those need to be cleaned up because of the shorts they could cause.
You will need some flux, soldier, soldier wick, and an iron.
I did it by getting a little soldier on the tip of the iron, place the wick over a few pins, and set the tip of the iron down on top of both.
When the heat transfers thru the wick your iron will sort calapse down on the board. Before anything gets too hot, pull(Gently) back and up. The loose pins will either stick to the wick or become dislodged enough that you can come back and sort of rake them up.
A rework air gun could probably be used too if youv'e had practice with it.

Edit: And when your done getting the pins, go back over the pads with the wick to get any shorts caused by the recent operation.

I am finally satisfied I didn't kill the Screen so I guess the protoboard is getting cut.
I finally realized the reason broadcast was making it work.....The battery was getting weak!
Charged battery and modified TV_Text a little and it's up and running without the broadcast signal.

The screen isn't big enough to display the sensirion demo so I chopped it down a bit to get all the data displayed.

After a few recharges on the battery I've noticed the voltage increaseing. Mine is now up to 4.19 volts. Maybe a diode on the supply line won't cut too much run time life out of it.

Just got the finished board in, when I noticed this. Hope the +4 volts didn't upset the Prop too much.
