DNA20D screen protector possibility to aid modders...

[retird]

It is my understanding that a screen protector for the 20D's display is being engineered by Evolv to see if it could be furnished with the chip. It is still in the early phase of possibility. The way most modders are securing the chip to the mod case seems to be epoxy, silicone, super glue, and etc. which may prove fatal to the display if the mod is dropped. The shock, I guess, could crack the display causing the display to no longer function. A cracked display usually doesn't effect the mod from continued use be it without a working display.

Here is a computer generated picture of the screen protector being considered....

The bottom is easy to make so the modder can do the base plate.
So the screen holder base plate is just a piece of wood, 3/16 deep and 1/2" wide.
It has two grooves, the deep one is 5/16" wide and .130 deep

The shallower one is 3/8" wide and 1/13" deep.


You'd make this as a strip on a table saw with a dado blade, then cut it into 1" long sections.

The non-connector side of the screen goes to the far edge of the groove.

This is designed to hold the screen in 1/4" foam trim tape. Its the stuff used for attaching trim to the exterior of cars and is extremely strong.

Then the cover plate goes into the top groove.

The user would cut a 3/16" x 5/8" (flat to flat, total length 13/16) slot into their case with a router. The shown screen protector is designed for a case thickness of 3/32"

The holder aligns the screen to the screen protector. The screen protector aligns the screen to the case. Glue the holder to the case and you're done.

Important things this does to note:

Shock mounts the screen. Foam trim tape is great for this, because its foam. An electronics friendly RTV silicone would be my choice for glue. Think rubbery. Remember you're mounting a piece of glass.

Isolates the screen from the outside world. This is hugely important. There should be about a 32nd of an inch air gap between the screen and the bottom of the screen protector. That way even if it gets knocked about a bit, the screen is never physically contacted.

Aligns everything for a nice clean mounting.

The screen protector is scratch resistant polycarbonate, so its pretty tough. Not exactly bulletproof glass at 1/8th of an inch thick, but the same material.

Alternative solutions should accomplish the same things, ideally. Shock mounting, isolation and alignment.

There should be more detailed drawings once a prototype is done.

I can attest to a broken screen not affecting the mod....unless you call counting button pushes for wattage adjustment affected

I think it's great they are looking into the screen protector, but if your like me and seem to be allergic to wood modding then the other piece won't get made or used. It would be really slick if they just offered both parts and I wouldn't mind if it was sold seperate or a second DNA20D option with screen protector.

The screen protector is nice and all.....but what I really want is some type of better options for remote mounting of the screen....like the buttons. I would trade both screen protector pieces for that

I'm not trying to complain, I think it's great that Evolv is creating a better product.

Plus I have to be carefull because karma is a nasty lady. I mentioned to Evolv that it wouldn't hurt my feelings if the screen went dormant after 30 seconds or even 60 seconds.....and now I have one that is permanently dormant

Very nice idea, I could have used this on the last mod I did. I played hell trying to find something to protect the screen. and ended up using nothing.
On the other hand Evolv has been very kind to me in the warranty department. So I am in for whatever they do to improve on the DNA20.

LOL... I've cracked a few screens while putting pressure on them during the build.... and plastic, delrin, or metal can be an option for wood if a person can work with them...I can work with none of them....LOL

I wonder if one of the current crop of 3D printers could make the base plate to sufficient accuracy.

I like this idea and hope it comes through.

A couple questions (to those who have the DNA20) is: How big is the DNA 20 screen length wise?

I looked up the datasheet and I couldn't find this measurement. I have my mod housing but not the DNA20 yet. And the best example I can come up with to explain this is...I would like to put the screen upright like how the screen is on the Evic. But my mod is only 1.5 inches wide so I don't know if this is possible. And I know it's not just the measurement of the OLED but the whole part of the screen that needs to fit.

Another option is to put the screen sideways if it doesn't fit upright...and I would do that since I like this housing so much. Sorry if this post is off topic from the screen protector.

Is this what you are asking:


The screen would require more than 1.50" (internal mesurement of housing) due to the ribbon cable (if the display is piggy-backed over the board) to orient it like the eVic. Your sideways option may be the best option.

From my experience the board orientation needs to be the same as the display (to achieve anywhere close to 1.5" ), so to orient the display like the eVic the internal mesurement of the housing needs to be big enough to allow the 1.30" long board (plus room for ribbon cable excess after piggy-backing the display over the board)and the thickness of the board and display (and the additional thickness of the display protector being discussed here, if used). The physical length of the display is 1.043" not counting the ribbon connection.

Side note: use care when moving the ribbon cable as not to break the internal runs at the display and board.

Mamu I have some info for you on the screens....shoot me a pm

 

[retird]

LOL....how about sharing your info bag......

Patience

I know, it's a virtue.....

This is what I would love to have. I have spent hours and hours searching for a frame where I can seat the display behind the frame - protected and aligned straight. And the frame gives the case a professional and finished look.

This one is a bit rounded - I need a flat frame but so far no go in finding one the right size or one where I didn't have to spend the $$ to buy the gadget that housed the frame.

But it's a one piece frame/cradle that has grooves behind the frame where the display slides right into place between the grooves.

Mamu you as much as anybody need something like this Solidoodle 3D Printer, 3rd Generation

 

[mamu]

Bummer about the wait time. What were you saying about patience?

***Now Accepting Pre-Orders***

In order to provide the leading edge technology at the best price, we're currently accepting pre-orders. When listed as "In-Stock", your printer is expected to ship in 8-10 weeks.

We have been waiting a couple months for a different printer at work....it's driving me effing nuts

Someone else mentioned that printer and I was shocked at the price.

Thank You for the info about the screen size retird.

mamu, I have been looking as well. Before I just decided to try my hand at a wooden mod.

BTW: Do you know when the DNA20 will be back in stock retird?

 

[retird]

They went back in stock two days ago but now out again....they usually are back in a couple days.

 

[Sad Society]

Thanks. I will keep an eye out.

Well no go on the solution I was hoping for

The display solder end uses a 0.7mm pitch and there is no connector that I could find that would work.

But I did find a less than optimal possible solution.....you will soon know why...and since I have a broken screen I might practice on it and see what the pita factor is.

First you would start by cutting the display cable at ~ the red line. Why....because from what I can tell it goes from the 0.7mm pitch down to a common 0.5mm pitch.

Then strip back the cable on both ends and solder one of these connectors on each end.

Then you would have a display that could be remote mounted via the connectors and one of these cables that come in a variety of lengths.....plus you maybe able to cut to length.

Like I said not optimal but possible
