its kind of funny that you told off the two forums members with actual engineering experience but hey if you just want a thumbs up here ya go :thumb:
Take a look in the hardware development forum and you'll find a thread from 2005-06 where a guy designed a slide-up in CAD and then pulled off a plexiglass mock-up which went in-car. It covers the math and servo selection behind the design. Also, I should probably give you a heads up to remove the pressure switch from the motor assembly of the drive or you wont be able to move anything. But again all of this would involve planning....which you said you didn't want to do....but looks like ya do. That said-what do i know....i only do this for a living :rolleyes:
Anyways expienece doesnt necesarily mean know it all..... The whole point of the Car PC thing is to experiment and come up with new ideas to get the cr@p to work in the car. If it doesnt work, then try something else. JustChat1 have you built a motorized screen or even tried? So who to say PatDaRat's idea wont work. Mathimatically maybe it doesnt work, but I have seen alot of things built that people say would never work, yet they do.
As for PatDaRat, i didnt see you didnt want to spend much time or think much about this. Your insane, even the smallest of designs for PC installs take alot of time and thinking.
please stand by as the world ends due to figure as you go planning.
also, you will want to take some measurements on the max depth of the radio location, and also try to allow for max depth with wires that might get in the way.
these are the make it or break it dimensions-- if you can't fit it to the dimensions of the dash, then you are either going to need to do some serious modifications, or need to consider other options...
most vga monitors are about 1.5" deep, not including the wiring harness, so you will probly need to modify the casing to make it slimmer. not sure what stuff you use, but i think i could slim down my 629 by about a 1/4" by scrapping the speaker, and backplate, and swapping it for a 1/8" sheet of lexan...
ok, enough negativity :), time for some ideas:
you can use a small hinge, or use a spring loaded hinge type setup-- if you have ever taken a floppy drive dust cover off-- like that, only with teh idea of being strong enough to pull the screen up.
i like the idea of the wire to pull the display up, and think that you could expand on this--
maybe use a small spring attached to the wire, so that the wire is actually keeping tension on the display during the proccess, and shape the area around where the screen pops out to make it smoothly pop out, and to allow the wire to guide the display into the upright position.
the hardest things that i do not currently have ideas for(but will probably be thinking about for a while) is to overcome the short travel of the cd drives, and to get the 1" height, and keep the entire thing sturdy..
i would try to do this in 2 steps-- first, get the screen to extend/retract fully in a 1" height(imo, the harder part), and then work on the method to get the screen up.
sometimes, by the time you get the screen to extend all the way, the method for getting the screen to tilt will just come naturally.
don't be afraid to try completely wierd stuff-- go get lost in a hardware store, and look for anything and everything that could work-- it could end up being a $10 tool for masonry, or a $2 plumbing trinket--they could all work, so don't limit yourself just to the hinges and springs section.
im not exactly sure who you think i blew off other then Maheriano and i guess you, if you decided to take it as a personal attack. I cant say i directed that at you at all but what ever.
id like add how i love the fact that you insert words into peoples mouths. please quote me where i said i didnt want to do any planning. figuring things out as i go does not necessarily mean im gonna stick a couple pop sickle sticks together and make a helicopter.
@soundman98 - hmmmm, spring loaded hinges sounds like a great idea. def gonna have to look into that. In my head everything seems very feasible and im greatly looking forward to the long search parties at the hardware store. should be fun.
the space im working with is fairly limited but can be made larger with little modification, so i may need to scrap the screen i was planning on. ill keep looking around see if i can find a thinner one or one that can be made thiner. all in all it will indeed be a challenge but thats sorta what i was going for to start with so it should be good.
the throw of the cdrom i think can be fixed by modifying the tray and extending it. the more i think about it the more im thinking im going to use my arduino as the controller and and use the cd-rom as a guide to how it should work. a motor to move everything in and out and a servo to pull the screen up and down. see this is why i like people who converse back and hit me their thoughs in a positive manner. gets me thinking and new ideas arise. i totally forgot about my arduino. i bought that thing and never could think of something good to use it for. i think this is a better solution then the cd-rom, and hell, with that i could have the screen open and close depending on if the system is booted or not. XD im liking this.
@ZX1Cruizer - you said you had the VM70 right? have you taken the casing competely off? The specs show 4" thick, is that with the headrest casing? just wondering if this screen can be made to fit my need.
