    it's a good job i can take it like a man! or i would cry

    I suppose i have no choice the amount of **** i subject people to!

    Get PMs of people who don't realise i am pulling their leg joking (americans normally - sorry guys. Go watch Monty Python films, Faulty Towers...etc etc and you will not get so worried!)

    now stop thread jacking, this is a good thread.

    As long as you have not mixed it with hardener and you put the lid back on the can, it will last months. As soon as you add hardener you have to use it.

    Hey yall thanks for the posts, I appreciate the interist.

    Moneyfink In regards to the bondo BRRMAn hooked it up
    As long as you have not mixed it with hardener and you put the lid back on the can, it will last months. As soon as you add hardener you have to use it.

    Scouse monkey thanks for the detailed response I will for sure look into those options. I have seen many of your threads and your expertise could deffanitly
    help me sort out this and couple other issues..Yes I am using a servo, as of right now I am using a basic stampII, it is embeded on a homerwork board (breadboard and stamp in 1 ). I was thinkin that when the opus is triggered on or just use the ACC wire that it would send the on signal to the basic stamp which would then run its processes (rotate servo and hold position). Then I need to trigger the basic stamp to go into its shutdown processes.

    Oh yeah Scouse thanks for the thread save appreciate it

    I have a couple other things I would like to use the basic stamp for but I would like to resolve this issue first. So SCouse old pal I would love if You could check in on this thread and help me out.

    Long enough post for now so i will put some pics up.
    And portugal thanks for the comments, much appreciated

    Oh yeah Moneyfink.

    There is no texture on the shift boot piece, It is just fiberglass sanded
    Down to a babys butt finish.
    It probably looks like a texture because it is primer. I used KRYLON
    spray flat black primer. You can find it at kragen auto parts or even
    walmart. The primer itself actually could make a nice lookin finished
    piece, I actally had thought of using it for the finished look.
    Hope that helps, if you got any other questions about fabrication I
    will be happy to help to the best of my knowledge. Believe it or not
    I was in the same exact shoes as you not to long ago.

    Don't mention it, sorry about the big 'bastard' appearing a couple of times!

    Here are the links to 2 servo testers as promised...

    http://www.hobbyengineering.com/appServoTester.html
    http://www.uoguelph.ca/~antoon/circ/archive/servo5.htm

    as you can see they cost pennies to make and all you need is a simple 5V to run them.

    was in work today so will clarify my idea:

    Circuit 1: potentiometer set to give open positon - when the ign comes live a relay switches power to this circuit and causes the servo to open.

    If you use a resistor and a pot (or two pots in series) you can have an angle adjusting pot (low value so god resolution) mounted somewhere discrete so you can adjust the angle for glare reduction.


    Circuit 2: This circuit is set to close the screen. When the relay is unpowered, ign off, and the reed switch is closed (get a normally closed one) i.e. the screen is open then this circuit is engaged. As soon as the reed switch detects the magnet (screen closed) it opens and kills power to the circuit. This reed switch does not affect circuit 1 so next time the ign is on and the relay switchs the screen opens.

    YOu could run the 5V off the opus as the opus will be still on when the screen is closing so should have enough time or you can simply use a cheap 5v regulated supply. Don't forget you can just hook the servo power leads up to the 5V supply as you only need to connect the white (or i think orange if a JR servo, or blue if a KO FET servo - very fast and powerful but need more than 5V) to the controllers as this contains the pulse signal.

    You could try be clever and just use the ign activated relay to switch the position potentiometers but for this you really need to run it off the opus so the whole thing shuts down.....

    ...actually this is even better - you don't need the reed swtich if you do this as the opus will take care of the powering down for you. Simply have 1 circuit with two sets of position poteniomenters that are switched by a relay activated by the ign line. The only problem i could see with this is the relay resistance altering due to contact deterioration so maybe the 2 circuits powered by the opus and switched on/off by the ign relay would be best - that way no conenctions on the position system.

    Excuse my writing this all out as i think but i jsut want to show my reasoning...

    my final recommended circuit (for tonight anyway):

    2 circuits:
    1st has 2 potentiomenters - one with low resistance so it has good angle resolution for trimming
    2nd has closed position setting
    Relay powered by the ign so when ign off circuit 2 powered and ign on circuit 1 powered
    Both systems powered by the opus so when the opus is on, the circuits are on. Opus will always power down well after ign is turned off so no worries about the screen not closing.

    You can also have a manual button to close the screen when the ign is on incase you get pulled over or are in a dodgy area and want to hide it quickly at traffic lights or summit.

    Hope this helps.

    Wouldnt mind some info about the stamp you are using. might be better for something i am still considering than a load of switches as i need to sequence servo action.

    Ok now for some information on the paint process.

    This process as many have also found out can be a real *****.

    First off the products i used for the finished project were both KRYLON spray paint
    (primer and paint). I used some other brands also but they didnt get me dessired results.

    So what i did was prime it, I used black(reasons: 1 black is the best color to
    find imperfections and you also want to use a primer that is closest to your final color)

    so then i sanded the primer and fixed my imperfections. I just basically sanded till that 1 coat of primer was non existant. Did this about 4 times

    maybe this will help some people

    1. 400 grit sand paper before primer
    2. 400 grit on primer
    3. 2 coats primer 1 final 400 grit sand

    Then paint it 1 layer and let it dry completely (I mean like over 24 hours, very very important)

    1. 400 grit sand till that whole paint layer is gone (sounds wack but it
    really makes a difference)
    2. 1 light coat then 800 or 1000 grit light sand
    3. then 1 really heavy coat if going for a gloss finish

    And MOST IMPORTANT let it dry at least 3 days before handeling

    Ok pics, the first is the spray booth, the rest are self explanitory

    Scouse thanks for all the info i love it. With regards to the basterd or whatever
    "no worries" and with regards to the

    Excuse my writing this all out as i think but i jsut want to show my reasoning...

    no excuse neccisary, I usually cut my post much shorter due to the fact that I dont think most people take the time to read the whole post or thread for that matter. Me when I find a thread I am intersted in I will read all 13 pages af every word if I have too. so with that said and you seeming to be the same way
    I would like to post a mega post on what exactly I am trying to achieve and why

    so scouse and who ever else likes to read entire ideas this post is for you. But mostly Scouse as he seems to like to generally help out and actually read everything.

    so next post for You scouse. But I am the pigeon pecker from hell so it will take along time to get it all down.

    meanwhile Scouse this buds for you

    GET A CUP OF MUG BEFORE ATTEMPTING TO READ

    Ok here we go, alittle background first to start it off.

    Computers and Me:

    Well lets see not much to say here. I really had never used a computer before three years ago. I mean I rember when my dad had a pc jr or something, all I knew on it was to play a game called "Zork" I think. It was an all text game, really cool though.

    Then about 4 years ago I had 1 time used the internet on a computer. Now I know you are probably thinkin, where the hell do I live under a rock. Nope, In a bueatifull city, Philly.

    Well I have always been into stereos and electronics and such but not computers. So One day about 2 and half years ago I decided to purchase a computer, and well thats all she wrote really. So ever since then I have basically been in awe of what they can do and what you can do with them.
    Also non of my friends are really into computers at all so I have gained all my knowledge from reading.

    I mean I feel I have learned alot of stuff in 2 years. I mean i cant program or anything but i feel I have achieved more than the common knowledge.
    I atleast know what services running on the compter actually do and how they work. I have learned how the north and south chipsets work and such.
    How to build a computer from top to bottom and things like the difference in a northwood p4 core and prescott core. Just the other night I learned how the pentium m does what it does.

    So take my computer knowledge of zero 2 years ago and now i am putting a pc in my car and learning how things like micro controllers work and such.
    Also I had no Knowledge of how electronics actually work and what a resistor even was. now when you use the term potamiter I actually know what you are talkin about. I am actually using 1 to adjust the level of my car sub.

    SO no with it established that I am the ultimate NOOB lets get on with the ideas. Speaking of ideas, I had thought about puttin a computer in my car about a year ago and actually put my tower in there with a hacked up xbox screen. I only put in there for like 3 days just to see if it could be done.

    So then the search begins...first I found a website about a jetta completlly pimped out. He is a member here, I dont remember his name but im sure you all know who he is. I think he makes a shutdown controller. Anyways then comes the ultimate find of all times..MP3car. Ever since it has been none stop reading, I mean in the begining I would literally read 9 hours a day 6 days a week on this site. no joke, I like many. or some have, almost lost my gf over this computer obsession. My girlfriend said she needs to strap a keyboard to her chest to get any attention..I thought that was funny, but true lol.

    Now I have a full blown computer in my car, well once I install it permantly
    anyways. I am really happy with the results but there are a couple things I would change which I will eventually, as everyone knows it is really never done.

    First thing I would do different is used a nvidia2 chipset based board with
    a low powered cpu. The only other major thing I would change is Using a OEM gps. Maybe also a bigger screen but to be honest with you I like 7"...lol..that sounds bad. One thing is that it doesnt blow you out night and also it doesnt matter if your screen is big during the day, if the sun is hitting just right you can forget about it. So that is why it was important to me to have good old fashion volume knobs and buttons. I really dont think just a touch screen for input and controls is safe at all, It really is dangerous.

    there are a couple other little projects that will eventually be integrated into the car as well. One of them being blind spot cameras in the side mirriors that will show the image on a 2 and half inch screen on the window A pillar. So you can see the mirror and screen in the same glance. I already have the screens and a camera I just havent had time to really test it out yet. The only reason I can think of why It wouldnt work would be because the screen is too small for the image to be seen clearlly. But I really dont think that would be a problem. I have a couple other ideas also but I am trying to plan out how I am going to them. So scouse if your still reading I would like to pm you with an idea that I think you could help me out with it. I remember a post somewhere where you said if you could "patent all your ideas", or summin to that extent. So I know your man the man for the job so just pm me sometime.

    BASIC STAMP

    what I was planing to do was have the stamp control my servo and a couple other things down the road. How this will work is the basic stamp will recieve a high signal (on), I was thinkin of using the opus 5v rail so when it turns on it will send the high signal. But I think I will have a problem with this, I will get into it next

    Then when the car shuts off it gets sent the low signal to trigger the servo to close. Now that 5v comes into play because I know normally the opus keeps the 5v rail live but I am planning to do the relay trick to get it to shut down.

    So I was thinkin, the basic stamp takes a big voltage range (within a cars voltage I believe). It can then supplly a steady 5v but I was wondering if this would drain my battery. I doubt it would but you never know. So then I would still have power to the servo so it could go threw its closing procedure when it gets the signal from the opus.

    As far as the info you posted scouse I somewhat understand what your saying..I get the jist of it anyway and all it takes is a little readin to get the whole jist of it lol. I like how you even thought about the allowing for movement incase of glare (you did read the thread ) and cops.I have had the screen turning the monitor with basic stamp using 2 buttons but what I dont have going is the atomatic open and close .

    That is enough for now my beek is starting to swell

    so thanks to scouse
    and any one else who has read this thread

    If you actually read this whole post (not thread) thank you and it would be cool to hear a whats up.

    so
    late....

    Why do you need that ?

    Congratulation by taking car pc to a new level !!

    9 hours a day of mp3car reading !!!Thats more than i could handle, your search for knowledge is going to compensate in the end.

    Keep up the goog work !!
