DNA20D screen protector possibility to aid modders...

5mm Version

Is there a cost associated to submitting another frame blueprint to shapeways, besides obviously from the time needed for modifying the CAD file itself?

Yes I'm aware of the distance problem, but with wood and a DNA20 you don't have many options anyway...

bap you kick so much ....

Wow, thank you very much bap!!!

 

[xpen]

Will order a few during the weekend, thanks

Ordered the new 5mm frames, they should be shipping in about ten days

Thanks again, bap!

Got them, that was fast... Here you can see both types, 1.5 and 5mm, side to side:





This black plastic ("Black Strong & Flexible" material, on Shapeways) is quite grainy, similar to asphalt so to speak, but on such a small scale it'll probably go unnoticed on a mod; worst case, a very light sanding - or just painting it - might improve the surface.

Kudos again to Bap, and Mamu!

PS: Shapeways' service is... heck, classy! Branded boxes and bags, for little more than two bucks apiece... would you believe that?

Hey, Bap: a huge THANK YOU to you and Mamu!!!

Great job!!! That thing is sexy!!!

Glad I could help.

Just for the record: my original idea of filling the frame with clear resin (in lieu of the polycarbonate window) was a disaster... too much distance, the image was darkened and the resin acted like a lens/fun mirror (reading totally distorted).

In the end I've used *no* window at all.. I'm confident the big distance of the screen from outside will protect it anyway. Cross fingers

Great job!!! That thing is sexy!!!

I can't see the pic.

Please have a look to the mod thread, I've now posted external image links - hopefully those will work.

What is everyone using to secure the DNA screen in the cradle. I just got a stainless steel frame and have a black one on order.

I understand the cradle itself is glued from the outside. I'm more concerned with keeping the screen in the cradle.

 

[xpen]

I've used a drop of epoxy on each corner of the display, I was afraid superglue might damage it.

As for the cradle, I've glued it with epoxy as well, but on the internal walls of the wood hole - not from outside.

Love epoxy, in case it wasn't clear enough

I apply a very thin line of clear epoxy (VersaChem 46409 5 Minute Epoxy) along the top edge and bottom edge of the display using the tip of a toothpick. Then I insert the display into the cradle and hold til the epoxy is dry. I do have the display lit when I do this so I can see to center left-to-right while the epoxy is drying (I have a breadboarded batt that I hook up to the DNA + and - input just for this purpose).

I adhere the frame on the inside of the case using gel epoxy (VersaChem 46509 5 Minute Gel Epoxy) all around the edges of the frame and on the underside of the display using the tip of a toothpick - when I'm done the whole works is covered in gel epoxy. If I ever need to remove the DNA and/or frame/cradle, I use a heat gun and that softens the gel epoxy so that I can remove the whole thing without damage to the DNA, the frame/cradle, or the case.

Hot glue essentially does the same thing as the gel epoxy, but hot glue gets gooey when using a heat gun to soften and ends up a big mess, gel epoxy does not as it just gets really soft and pliable.

All other parts (switches, connector, etc) I use VersaChem 47809 Plastic Welding to adhere inside the case.

I buy the epoxy at jbtoolsales.com - great prices and fast shipping. Local auto stores (like AutoZone) and home improvement stores (like Lowes) also have VersaChem epoxy.

Thank you Mamu! Off to order some epoxy.

 

[Mike88]

This is simply amazing and extremely inspiring! Hats off to both of you. Mamu, would you recommend a different epoxy for adhering the cradle to an aluminum case?

Has anyone had an experience or any pictures with any of the other materials its offered in?

 

[mamu]

I use gel epoxy to adhere the frame to the inside of the case with both plastic and aluminum cases. I scruff up the area inside the case where I'll be applying the epoxy so it will adhere better.

I've ordered various types of the material the frame is available in, but have only used the transparent and the strong, black, and flexible so far.

 

[xpen]

Mamu, do you think there's a type of clear epoxy suitable for making the frame external 'glass'?

My first attempt at it was definitely _not_successful...

I tried working with clear resin - no go for me either.
