If you have any ideas on how I could get a cover for this, or how to move the unit back about two centimeters, I would be interested in listening.

Obtain a picture of the stock radio and have it printed out life size. Then just squeeze it in there.

Thanks for the logo link, that should help immensely.

I got the LCD panel and the motherboard this past week, so I can finally start to get the bezel into shape.

The LCD will be mounted to standoffs, and the standoffs will be screwed to some mounting blocks that sit in the radio area.

The bezel will be secured in place with velcro, or something similar.

I found that one last night as well - fantastic resource!

C!

any update on finished product would like to see some pics

i was gonna install a lilliput screen in my civic, using bondo reinforced with fiberglass. i told my project to a guy in my CNC machining class and he mentioned about cracking over time and that i should use rtv to mold it and make a single piece. then i looked it up on here and found this guide. and i was wondering he mentioned something about using microballoons and milled fibers. is this a good idea?

I haven't worked on the bezel for a week or so, as I've been working on the wiring of my LCD.. which has turned out to be rather difficult, very small wires.

Molding it out of one piece of material is a good idea.

Microballoons is basically a powder-like material that you can add to resin as a filler, to take up space and make the piece lighter. Think of them as microscopic glass balls or balloons, filling up space with mostly-air.

Milled fibers are good too, for strength.. basically fiberglass strands mixed into the material.

wow, interesting stuff....can this be used in pretty much anything or only for molding?

What do you guys have against magnets? LCDs aren't affected by magentic fields the way CRTs are. And they wouldn't have to be that strong. Four small ones, one at each compass point, would hold a plastic cover perfectly in place. Not to mention the clean look since the magnets could be on the inside.

BTW, great work on this writeup. Because of this, I've been able to mold smaller parts - replacement buttons mostly - but plan on doing bigger things. Thanks for sharing your work.

So you can say with certainty that exposing an LCD screen to a magnet in close proximity won't have any adverse effects on it?

I ask because I know a little bit of how CRTs work and why they are affected by a magnetic field disturbance, but I don't know how LCDs work.

At least for me, it's just not wanting to take the risk at all because the LCD screen cost me so much to begin with.

Saab9-5 · 03-29-2005, 05:27 AM

That is correct. Active-matrix LCDs depend on thin film transistors (TFT). Basically, TFTs are tiny switching transistors and capacitors. They are arranged in a matrix on a glass substrate. To address a particular pixel, the proper row is switched on, and then a charge is sent down the correct column. Since all of the other rows that the column intersects are turned off, only the capacitor at the designated pixel receives a charge. The capacitor is able to hold the charge until the next refresh cycle.

You know that a CRT uses magnetic fields to aim the electron beam but LCDs just don't work that way. To even make sure I was right, I placed a magnet on top of an LCD of an old laptop and ran it for two days straight. No problems. As for the magnetic faceplate idea, I was only thinking of small magnets, no bigger than 1/2" in diameter.

btw - old cdrom drives have excellent little magnets in them.... quite strong for their size

that info has given me a world of new ideas... sweeeet.

Just take a look at the new cell phones. They have both magenets and LCD screens with no problems..

Are you going to use the Polytek 1510 for your final bezel ?
I want to put my epia pc in a hidden compartment in the trunk of my 1'er.
It is a really weird shape and want to pour a custom enclosure in that shape.
Is the polytek stuff strong enough for such a build ?

Thanks

BTW: How's the bezel going ?

vipergda · 06-30-2005, 07:20 PM

hey wondering how the project is going and y u stopped posting hope u didnt run into any big problems would love to see your progress
