    WORKLOG: Motorized Screen

    YOUTUBE VIDEO:

    [media]http://www.youtube.com/watch?v=plLU0GdiaYw[/media]

    got started over the weekend on motorizing a screen in the map pocket of my Mazda 6. i've decided to go with a linear actuator, which several other people have done as well. things are going well so far. i've modded the map pocket, gotten the screen attached, and tested the mechanism. all that's left to do is to get it installed in the car.

    several pictures are attached, and a test video can be found here:

    i started the installation last nite, but it got dark so i had to quit. i got as far as getting the actuator seated in the dash. that required a bit of cutting, but nothing too big. i was able to test everything in the car and it worked great. just need to make a few minor adjustments. didn't get a chance to take any pictures last nite and won't be able to work on this again til friday. but i'll be sure to update when the time comes.

    that actuator is massive... clever design though.

    I like it, where did you get the actuator and hardware from?

    well, i finished things up. didn't have to do much except line things up and run the wiring.

    i didn't really get any more pics, but i shot a couple more videos. check em out here:

    overall, i'm pretty happy with the way things turned out. someday, i hope to have enough money to buy the entire motorized assembly from china. but this will do for now.

    as far as the loudness, i gotta say that it is pretty loud. but i didn't really do anything to try and dampen the noise either. although, i can live with it. it only lasts for a couple seconds at a time. in someone else's how-to, he wrapped it up and sealed the opening with dynamat. i'm sure that helps a bunch.

    also, if you notice, there's a delay as to when it opens with respect to the ignition signal. this is because i actually wired the ignition signal for the actuator to the power line to the monitor, which is powered by a carnetix PSU. the 12v rail on the PSU is on a 5 or 6 second time delay, so that's why it doesn't open up right away.

    after a bit of searching, i found a 5% discount coupon code for trossen's store: mp308. all in all, i spent a total of $152.21 for everything and shipping.

    No kidding. Check out the specs (from the linked website):

    12 VDC
    4" stroke
    110 lb. max load capacity
    550 lb. max static capacity


    That's more than my biceps!

    they had some pretty cool micro actuators on that site though. Probably could have used the high force variant to zip that thing open with barely a whisper. Eh. Everyone's a monday morning quarterback though. I still like it.

    You'll probably have better luck than the one the other 6 owners are ordering from china.

    i though about using one of those. i was in contact with a guy at Firgelli and he was really quick at answering my questions. i was interested in using the L12 mini actuator, which has yet to be released. i ultimately decided not to go with it since it only provides 5-lbs of force. i'm sure this is more than enough to do the job, but i was still a little skeptical. also, i was worried that the screen would shake while driving, considering its small size. but who knows? it may have worked, but i'm impatient and wanted it to work NOW.

    i also looked at getting the LCD box from japanparts.com, but that was still a little out of my price range. and, of course, the screens coming from china are definitely out of my price range. but i hope those work out for the people who did decide to get those. they're pretty sharp looking units!

    thanks, man! i assure you, the screen is plenty bright. i can see it fine during the day, even with sunglasses on (unless the sun is shining DIRECTLY on it). it just got washed out by the camera (it's not a video camera, just a digital still camera that can shoot small videos).

    mounting actuator

    Hi there, I am trying to follow your tut. but how did you manage to mount the actuator inside the car? The only way I can see doing that is more cutting inside the car where the vents/plastic are??
