Wow thats a great feedback level. NOT!

Looks like this one. $47.49 plus shipping or you can make an offer!

ebay.com link: HDMI VGA 2AV Reversing Driver board 7inch AT070TN90 800x480 lcd display

That ones has some type of opec bezel not black.. But it's a similar screen

For those not lcd pixel educated which is the best resolution of those listed above? 1280x800?

there goes your warranty folks

Yes...bigger number = more pixels and better resolution. Ideally you match the resolution WOZ was built for though.

LOL. I didn't realize that first seller had such poor feedback. Better price now and it seems like there are a few more of them on Ebay today even.

Is there a 5 inch variation that would look good? the 7 appears to be a little too large IMO....

That's NOT what she said!

By the way...that 7" is TINY!

Not sure that is going to work on an LE. The clearance is right around 7mm.

I bet I can make it work...just not sure how it would look when finished.

I'd remove my wooden apron, reverse-engineer it, machine a prototype (or 2, if needed), then I'd machine a stepped-thru pocket from the underside of the apron, then mount the screen under the apron.

I'm sure this approach would require me to modify the apron that lies under the wooden apron cover. It all depens on the total thickness of the LCD screen.

I've thought about making a new wooden apron for my WOZ anyway. I was thinking of making a slightly nicer one out of solid oak.

I was looking at the specs on the 7 inch screen and the screen is 3mm thick. The additional 4mm seems to be coming from the double sided tape used to hold it firmly to the apron.

If you can figure a way to secure it to the apron without 4mm thick double sided tape, I think it would work even with the wooden apron on the LE.

That's what I was wondering. I'd still be in for this mod though if it'll work on an LE. Looks great!!

Hmmmm. Good to know. Thanks. Maybe this could work after all.

I know that Levi_Br hasn't posted his tutorial yet, but by looking at the product page and his installation I am not seeing how it would void the Warranty any more than adding any mod to the game would. The WOZ Winkie Target mod seems more invasive than this does.

It looks to me that there is already a unused VGA or a DVI video out on the computer, that you plug into the product's board. Make a Y cable that taps off a lightly used 12 volt harness (or find an unused 12 volt someplace) that keeps the original circuit and powers the Mod's board. A little mounting of the board and the screen, maybe fiddling with the video sync and such on the mod (only) and Bob's your uncle.

I am probably missing some critical component or step here. But it looks to me to be a reasonably safe and simple addition. As long as you don't start cutting wires, it could be as simple as plug and play.

I was responding to someone asking about Williams DMD's.....which I responded any pin with a DMD could use this.

4mm is pretty thick for tape. A few small pieces of museum putty would probably do the trick here, and is less likely to mess up the apron when removed.

Not to offer any official comment one way or the other on this mod, but I would suggest that the most important thing is the aspect ratio and keeping it the same as the main screen (16:9) regardless of whatever resolution it's running.

Resolution helps, obviously, but at some point it's like... Do you REALLY need a 4K phone? You already can't see the pixels (ooooooooh RETINA DISPLAY).

Just be glad this works at all.

He edited the link.

Then it should work on an WOZLE. I'll give it a whirl.

Levi- if you had sold it instead of giving away your secrets you probably could have made $400 per unit based on the way people go nuts about mods around here. I'm sure the mod companies will take note and replicate it.

That said, thank you for not doing that. I don't have a WoZ and wouldn't want to mod it if I did, but I appreciate your style.

I clicked on the Ebay listing that was listed earlier and found the type of display used.

N0701CG-LD1 -- The specifications give it a depth of 2.5/4.5mm (Min/Max). Add 1mm for the double sided tape for a total of 5.5mm if there is 7mm of clearance in the WOZLE you should be able to fit with a scant 1.5mm to spare.

Here are the specs:

Thanks for posting this....

I see another project I'll be doing soon.

Brilliant tutorial Levi,

I watched your TOTAN Youtube video and would be really interested in putting the video mod
in my TOTAN.
Can you please do a simular instruction tutorial for the TOTAN DMD apron mod.

Thankyou ...

I assume, I can just install a standard apron on an LE?

Very nice mod!

I'm normally not a huge mod guy. However, I do like this and thanks for the OP in starting the thread and making a tutorial!

Nice mod, great work

This could be a good combo with Smartdmd. You could than use a hdmi splitter between raspberry Pi and the lcddisplay which replaced the dmd and hook up the extra apron LCD

Will give this a try

hmmm

had a 7inch display lying around approx 6 mm thick. Did put that on a Stern apron ACDC and the glass clearly wouldnt fit anymore. Estimating only a few mm of space available between apron and glass

Is looking like a no go or the very thsplay should be really very thin

To be investigated

I'm a little concerned about the control board being so close to the hand rail, if someone would produce another apron that is cut for the display and can have the control board tucked away under the apron, or if I can get another WOZLE Apron, I think I'd be a moddin mine, but I don't want to cut my numbered apron up., but I really really really like this mod!

I'd love to see the connection to the A/V board.
Did you split the ribbon cable between the AV board and the DMD Display?

Several recommendations:

(1) I'd CNC a custom wooden apron topper (like the LE machines) that can accommodate the LCD screen. The wood can be painted and clear coated.
(2) I'd investigate mounting the LCD driver board underneath the apron. You may need a larger ribbon cable for this, but they are available. You can use a 40 to 50 pin cable converter board.

What is the power draw on the LCD driver board?

Very cool MOD. I was toying with the idea when I owned a WOZ - nice work

As I mentioned yesterday. This is something Oga and I have discussed several times now - it's in the works.

Oops

Reinvestigated today

With a stern there is really very little room between the glass and apron, just a few mm.

That means the apron has to be modified to make this fit. If i can get hold of an extra apron i will definetly give this a try. For now it will have to pass as i am not cutting in my orignal apron. I like my mods to be reversible

Everything I make is 100% reversible, no worries there

Anyway, this is a topic for another thread.

Props to the OP for his handy work.

This is great idea, more useable for the player than the big screen at the back

that is cool....

That would be awesome!
