  • My custom motorized screen plan

    Hello all,

    Iíve been poking around this forum off and on for a couple years now and I must say that there is no better place to find info when doing a car pc install. Great site, love it.

    I recently purchased an 87 Nissan 300zx. The radio bay is a 1.5din. Iíve been looking and looking for an affordable solution for my touch screen but have not been impressed by the options. Ideally Iím wanting to have a hideaway screen and separate headunit. I donít want the carputer to run the radio so Iím pretty set on having a headunit too. My issue comes in at this point. How will I fit two 1din units in a bay that is 1.5din. I do not want to tear up my dash making it a double din. And all the units I find that are a radio and a vga touch screen are super expensive and typically ugly.

    Now a quick background before I get into my idea/plan. Iím a PC technician by hobby and career and I love putting things together that are flashy with lights and look good. My most proud creation was my xbox360 case mod.

    Now my plan. I will be fabricating my own motorized screen that will be made to work in my limited space. To accomplish this I will be using a broken cd rom. The mechanism in the cd rom that moves the tray in and out seems like the best idea for this. After taking out all the parts from the cdrom that will not be need (i.e. the laser and motor that spin the disk.) I will be left with a vary roomy box with the tray mechanism in place and functioning. I will then be attaching the screen to the modified tray and cd rom to the screen with some small hinges. On the top back side of the screen I will have a wire that is attached to the cd rom casing. When the screen comes out it will put tension on the wire causing the screen to stand up. Now all the fine details will be worked out during the fabrication (thats just how I work ) but Iíd like to hear thoughts you guys may have on this.

    Now Iíve been looking around and have seen people trying to make their own motorized screen before and having a hard time working everything out, but I feel fairly confident that using the cdrom will make it extremely possible and easy. So please no bashing on how itís not gonna work or how I should just buy a pre-made one. When Iím done I would have saved about $200 and had to joy of creating something myself. So, let me know what you guys think.

    I think you'll find the CD-ROM mechanism isn't strong enough to push out while tension on the wire pulls the screen up.

    Also, I think you'll find that the wire is springy, making using it as a touch screen difficult and allowing it to bounce as the car hits bumps.

      i actually thought of that issue after posting :P. But by replacing the motor with one a litte more powerfull i think i can overcome that issue. And as far as the screen staying in place, the wire will keep it from going forward and i plan to have feet on the back side of the screen to keep it from bouncing backward while using the screen. Like i said the minor details will be worked out as i put things together. But those are good things to point out.

        This is the wrong way to approach any design. Everything to do with design should be worked out prior to build.

          i thank you for you thoughts. but to eatch their own. i personaly like creating a challange for myself. and whats the point of doing something if its not fun the entire time your doing it. i find planning everything out although being a good idea is less entertaining overall.

            I like figuring out things as I go along too. I get the major points straight in my head and then go for it. Anyway, I was thinking maybe a flip down screen would be easier. slide out the screen and when it gets out far enough gravity would take over. Of course, getting it back in might be problematic. Keeping it still while you use it and driving would need to be figured out too.

              i don't know, i can see both sides-- usually, by posting on a forum, i take it as looking for help, and thinking about it, and planning before building

              but, i can also see doing it as you are--but, i usually go at it and figure it out as i go, and then post the results

              either way, enjoy the project, keep some spare cd drives nearby cause the first one might not work out so good...

                i am indeed looking for suggestions and insight from people on my attempt. As bug pointed out im more then likely gonna have issues with the wire being a little springy. So this is somthing i will look into when purchasing the wire or w/e im gonna use to make the screen flip upright.

                @RonsRed88 - Givin the spot i have to work with i just might have it be a flip down, i could go either way with it. But yes the getting it to flip back up part will be a trick. Dunno really, guess ill cross that road when i get to it.

                Ill have my screen ordered by the 15th so that week will the be the week of my build. Ill post pics and progress on this project for anyone who may be interested.

                  Flip down is the only way you'll pull off something your happy with. You would need a dual track design for a slide up which would require the planning you don't want to put in.

                  the only warning i'll give you is that I can promise it will be more expensive then an off the shelf unit. You never realize it until you look back at the completed project and find all the little things you spent money on to pull it off.

                  Flip down is fairly easy if your mechanically talented just keep the screen hinge angle high enough that you can pull it back up.

                    lol... people on here are so negative. Come up with what you think is a good idea and people will poke holes in it fully believing that it cant be done. All i gotta say is, only time will tell and negative nelly never accomplished anything.

                      i have some ideas with getting a screen to exend upright, but the limited travel of the cd drive might not work for this. the cd tray would need to extend the height of the monitor, and then a little more...

                      maybe a linear actuator would work better, but is no longer cheap...

                      with that, i think that the biggest issue that you are goign to run into is the travel of the cd drive, not the actual usage of the cd-drive-- but good luck, and i hope you can prove us wrong

                      and from my experience, Lowes seems to have more little peices-parts than menards and home depot

                        That is 100% untrue. Everyone works differently. What I do is order a second of what I want to build, build it, and if I do not like it, change it, then once I like the way it is, make a perfect clean copy on the second one. Of course my install has alot of parts I cant seem to find, so I have had to experiment with only one thing. In the end its worked out for me.

                        I think they where just having a bad day. Usually we are very insightful.

                        I will chim in on the situation and unfortuantely its negative and positive.

                        Have you looked at the VMI70 from http://short-circuit.com? It is litearally one of the only motorized screens left. Problem is motorized screen with VGA ware very rare. Modders that decided to basically modify their dash to a double din, basically killed that market, so companies stopped making them. Thats why the EBY701 is so popular. I originally had a motorized screen, but it didnt look OEM, at all, so I went with a double din with mine originally having a 1.5 din. My understanding is that the VMI70 is a server screen. Its made for server cases so the IT specialist can see whats going on. Comapines though are selling it as a car screen and unfortuantely it cant stand up to the constant opening and closing. Also because it is made for server cases, it has support on the back when opened. In our vehicles there is no back, so if you hit the touch screen the whole screen wobbles back then forward, which kills the gears. The other issue is these people use plastic gears when they should be using metal. After awhile the gears get worn down.

                        I want to install three screens in my dash, one in the middle, then one for passenger, one for driver. i tired to build my own like you because I wanted to use EBY701 units, but I ran into soooooooooooooooooooooooo many road blocks that I decided to install 2 VMI70 screens and call it a day. You are facing alot of issues, but if you decide to do it, I give you props. The only one I have seen build their own from scratch is BugBite, I think. He is the one you want to ask for advice. I will note though that he built his on the top of the dash, which is less headache. OHHHHH I just remembered, coucouillu, basically took a motorized screen but redesigned it to look OEM. He redid the original radio, intergrated the motorized screen. Take a look at his work log and P/M him. http://www.mp3car.com/vbulletin/work...full-pics.html

                          Hmmm....I did see one design for a DIY motorized that I thought would work pretty well. I'll have to take a look for it.

                              Id love to hear what other ideas you have. I have several ideas in my head as well. Just hard to say what will and wont work till i get into it. Sadly i cant really get going till i have the screen and payday just seems so far away.

                              Thank for the input. I have seen that screen but regretably it would take alot of modification to fit it in the .5din area i have to work with. Although im sure its do-able, im thinking im really gonna go for a DIY, if for nothing els then for the self satisfaction when/if i get it working. Im thinking im going to be useing the VM70 from http://www.short-circuit.com/

                              Ill take any advise you have to offer and i would def be interested in design if you locate it.

                              funny how others have provided useful information with out being a d-bag.
