I think I'm in for some of these, but when you say the best video mode is PAL, does that mean they only work in PAL?

I'd like 2. I can PayPal as soon as you get a shipping price. I'm in Alabama zip code 35046
if that matters.

No, they receive whatever output you're sending from the camera via analog video RCA. But the PAL setting on the Canons seem to allow more screen real estate; less edge cut-off on the displays.

UPDATE 09/08/2010: I have purchased the remaining lot of these displays; after recent orders from DIY members, there's approx. 16 remaining displays, or 8 dual displays systems, i.e., 8 orders remaining. (I do have some displays coming in that don't have main-board cables either. PM me for details, as this is not for the faint-of-heart electrician)

Done.

How much are you asking for these? Could you put them on ebay? Would you accept paypal? Is there a way to get expedited shipping or overnight shipping on these? How can we be sure this is not a scam? Thanks.

How much are you asking for these?

The prices noted in the initial post are still valid.

Could you put them on ebay?

I don't have plans to list them on eBay because it would cost more to list them, more to sell them. These LCDs work extremely well for book scanning. They are finite in supply, so I've decided to sell them at cost to our community of DIY users.

Would you accept paypal?

Yes.

Is there a way to get expedited shipping or overnight shipping on these?

Yes.

How can we be sure this is not a scam? Thanks.

We can setup a C.O.D. or other form of 'ship before payment received', but Paypal generally covers both buyer and seller when a potential customer is uncertain about the service. Other DIY users/members have purchased these LCD sets, however I'm reluctant disclose their profiles as a basic privacy measure. Previous buyers are more than welcome to chime in and review the product and their purchase experience here. If you want to purchase, please re-read the description, PM me with the quantity you want, if you want AC adapters wired into the displays, and provide a shipping zip code so I can prepare a quote. (and specify your shipping preference.) I generally ship Fedex w/tracking.

The displays are tested and inspected before they ship. Worst case scenario you don't like the LCDs, you can return them within the first week.

univershal:
Thanks for responding.

Embarrassingly I realized you had posted the price in your original message only after I had made my post asking about it. Unfortunately there was no way to edit my post after the fact.
I still have a few more questions to ask before I can make a purchase.

How well are these screens protected for shipping?

What should I do if its broken or cracked on delivery due to mishandling during shipping?

Will the screen display the full "edge to edge" picture produced by the camera? (currently I have two monitors that will not show the full picture from my cameras).

Thanks. I will PM you my info for a quote after shipping plus AC wired into the boards.

They are packed well, they are also durable units. If you receive a damaged unit, I will either replace it or refund you.

I personally cannot guarantee a full edge-to-edge transfer of view finder-to-LCD picture reproduction. But most cameras with an analog out benefit from setting the 'video-out' on the camera to PAL on these 12" LCDs instead of NTSC. I've experienced ~98% view finder-to-extrernal transfer on my own set of these LCDs There are additional micro-switches on the main board that might eliminate any margining you experience, however, that is beyond the scope of my expertise or intent for the sale.

Resolution, quality and screen real estate depend on your cameras. These displays are intended as reference displays. They serve the purpose of checking to make sure the book is centered, the cameras are aligned, the cameras fired properly (i.e., no camera firmware freezing), the focus sensor is operating correctly, and missed pages are accounted for in a faster manner should you pause during your scan workflow, etc. The LCDs do not project finished, processed image resolution; they perform--but not limited to--the above in a low power footprint.

This post is to show how I modified the power cables (being sold as an option by univershal with these monitors) to give them on off switches and to protect them from short circuits.

Quick note:
The monitors were shipped to me quickly and they arrived in really good condition. I have not yet had a chance to see if the image I am viewing on the monitor is the entire image viewed by the camera (this is important for cropping the book-page with the camera, instead of with software afterwards).

I ordered these monitors wired with the AC adapter because I was curious what that meant and I thought it might be to my advantage to receive it that way. The AC wall adapter that I received with this purchase is an AC power adapter that outputs 12V at 3amps. The end of the AC power adapter that plugs into the two monitors had its ground and positive terminals split so they could provide power to both monitors. Here is an image:


As you can see from the image these are bear metal connectors so if you use these you have to shield them with electrical tape to avoid accidental short circuits (mine shorted out when the plug for the ground wire came in contact with the metal housing of the monitor. Note: these monitors seem fairly fault tolerant and mine works great even after the short circuit). This type of connector shielded with electrical tape makes it difficult to plug and unplug as needed. The monitors came with cables soldered to their power receptacles on the circuit boards. The other end of the cables (the ones soldered to the monitors circuit boards) had the matching connectors for the above pictured cable receptacles coming from the AC power adapter.

Instead of using these I opted to make my own connectors and switches for turning the monitors on and off as needed. First I de-soldered and remove the power cables that were added to the monitors circuit boards. I also cut the bear metal receptacles from the end of the AC power cable. Then put together all the parts I purchased from a local store to re-create the power splitter, on off switches, and connections for the monitor.
Note: The connectors that seem to fit the circuit boards power receptacles were labeled as "size L" at Radio Shack. (I'm not sure if that is a proprietary size label chosen by the store or if it is a standard size).

Here are some additional images and the circuit schematic for the switches:
