Cluso: I'm starting to think you have the right idea with your dual purpose USB/PS2 connectors...

Forrest: This one is using recycled displays, either "as new" or "used" varieties... I hope to sell a breakout board (populated with just the bare minimum parts, no propeller) with "used" display for ~$50 or so. Fully loaded, I suppose it'd be around $125 or so. Maybe I can do a version without some things like VGA/TV connectors, RTC, USB, and accelerometer for under $100.

Going from "used" to "as new" will add ~$15-20 dollars or so.

Yeah, I was worried about the cost of the accelerometer pushing the system cost too high with a questionable return-on-investment, but if they're dirt cheap.... Also, even if the board wouldn't be directly used very often in a robotics application, that doesn't mean that one wouldn't test out a robotics scenario needing an accelerometer using your proposed PSB system. Moreover, one might use the PSB board in a robot directly, too, especially if it's not so big, say up to two or three times the size of the PSM. And there are probably plenty of non-robotics apps, too. So I think my comment was a bit near-sighted.

I still like the idea of a RTC, but can understand if it's not feasible due to board space or whatever. And maybe I was wrong about the RTC needing to be backed-up by a separate battery. I guess I was thinking that the PSB wouldn't get very far on batteries alone due to the display, maybe a few hours or a day, depending on the size of the battery. But that might be enough (though maybe such a short-lived clock could be simulated by the PSB in such a case if the time were entered), and larger batteries could be used, I guess. Also, the PSB might be powered from the mains. Anyway, I just hate having to reset the microwave's clock when the power goes out....

Regarding my comment about wanting audio-level output for a speaker (1W, mono), I still want, but maybe that would load the power supply, expecially if only USB-powered. Also, one watt is a lot of audio power for non-boombox applications, and, for signaling or alarms, other devices are available. But I had in mind being able to play a mono voice-quality message at sufficient volume. Oh well, one can dream.

Well, I didn't see a way to really make this PSB board into a breakout board because it's now just too crammed full of stuff...

But, I did have some time today to draw up a breakout board... Here's what it looks like (I haven't ordered it yet, just in case anybody spots a flaw):

I think you definitely must bring out most if not all of the RGB lines, otherwise its too limited.

Rayman,
Do you have plans of selling the display/touchscreen alone? I am interested

It's Only A Stupid Question If You Have Not Googled It First!!

Rayman,

on this side of the ocean another, very similar display is available, the LQ043T3DX. The connections are very similar but this one needs also 5V. You may want to add a pad filed for the corresponding connector(s) to your break-out board that btw look very nice.

I am planning on selling the LCD by itself... I understand there's very large quantity available...
What I can do for you guys is post the ExpressPCB files for this breakout board. That way,
You can modify it any way you want...

I'm not sure a breakout board with more color pins is a good fit for the Propeller... The nice thing about this system is that people with Protoboards are equivalent already have pins set aside for VGA and I2C. If you reporpose and/or share those with the LCD, then you only need five free pins for full functionality.

And, you could get by with just 3 pins, but not using the Touch IRQ and tying DON to BL...

Just got my big box of screens today! Haven't opened it yet, but I think they're the "used" variety. In that case, I'll be selling them soon for $15 (plus shipping).

Brian: Yes, I can sell just the screen...

Ray, can't you just use some of the color pins and tie the rest to ground?

Jazzed: It's better to do as Jim suggested, because this way the count goes:

00000000
01010101
10101010
11111111

Which is perfectly uniform steps...

Just opened the my box of "used" displays... Wow, they are really in great condition! I just tried a couple out on the prototype PSB and they look beautiful.

Only slight problem is that certain areas of the screen are less sensitive than others... I think I can tell where on-screen buttons used to be! Testing out the PSB Paint app, there are a couple places where you have to press harder than the others... This is because I'm constantly measuring Z (how hard you're pushing) with controller to decide if the user is pushing hard enough to count or not... Anyway that algorithm will need some tweaking with a display that has been used.

I may be able to sell these "used" displays for $5 each. Isn't that insane?

I just may have to buy a bunch of "used" displays off you... crazy good price!

FYI, the only reason I did not buy one of the PSM's at UPEW was I did not want you to be annoyed if I produced something similar (but Morpheus based). I just may have to get one of your new 4.3" PSM's...

I'm definitely interested in getting a few.

I'd also be willing to do a bulk order and forward them on to other aussies if it would save us on postage.

I will definitely buy a couple, especially if you can sell them at $5 each. That's just too good of a deal to pass up.

Maybe I've missed something, but given the spec on the display (PSP clone no?), it seems one could do 5:6:5 (65K colors) with separate data color lines instead of being constrained to VGA DAC and the Propeller way, have all Propeller memory available for programs instead of video buffers, the video would be crystal clear, and users can leave everyone else's junk in the dirt. Of course one could do better with the same setup connected to a bigger controller like a 256KB AVR ex-Propeller.

Bill: Don't worry about that... I'm liable to copy some of your Morpheus ideas pretty soon!

Also, since I'm selling the actual LCDs for this one, I'm actually going to post the breakout board diagram and files with no restrictions...

Jazzed: I'm not using a DAC, it's a digital interface... There are 24 color pins 8:8:8. But, you can't really do a versitile 1 Prop system using very many pins for color...

But, perhaps I should do a breakout board with all the color pins exposed for people who want to play around with that...

I would love to have this LCD driven to accept an NTSC or S-Video signal. Then my dreams of making a multi-screen editing system would be closer.

Is there a NTSC driver board or chipset that might work with this LCD?

A versatile breakout board would be useful. I'll buy a few of the LCDs without the breakout.
paypal? other? I'm at the same address. Thanks.

for $5 i will buy 5. Can you send me the spacing and pin order so I can design into my newest board if I have space. Currently the IDE interface seems to be the board hog.

propmod_us and propmod_1x1 are in stock. Only $30. PCB available for $5

Want to make projects and have Gadget Gangster sell them for you? propmod-us_ps_sd and propmod-1x1 are now available for use in your Gadget Gangster Projects.

Need to upload large images or movies for use in the forum. you can do so at uploader.propmodule.com for free.
