Here some pictures of the venitlators. I’m most pleased about the way I placed them. Not in the middle, is much cooler for me.

The pictures of the the lighting will be for another time

[andym85]

Here some shots with the blue lighting.

These are made during the daylight. I think most people will see the install in daylight conditions.

This pictures is made at night.

Pictures made through the side

[andym85]

Because I want the people to see the inside of the PPI, I had to screw off the top.There was a little problem though. The cover held the power amps in the cool paste. I managed to make 2 new copper bars that do the same thing.

Milled a little diagonal side on the front.

Here they are mounted. Each bar is tightened with 4 M4 screws.

If you look closely you'll see why I made the side diagonal.

It was a little too short on the pins where the power amps are tightened with.

I glued a piece of self-adhesive vilt on the bottom. I did this to prevent scratches on the plexi and on the paint.

Once this was done, I screwed the plexi on.

The plexi glass is painted in the same colour as the car. TITANSILVER

The slots I milled into the plexi, don't catch the eye like I planned it. But when the lights are on...that'll change.

[andym85]

I forgot to post these pictures. They’re about the plexi sides who will get next to the amplifier.

These are also sprayed in the silver of the car.

For the amplifier-part, everything is mounted into the car. I’m going to wait some more before posting pictures.

Sorry dude’s.

In the meanwhile, I didn’t sat still. For about 10 years, I have something in my head, that I HAVE TO try sometime.

Well, now that stage1 is complete (and it all works perfectly), it’s time to do so. Here and there there are some things I need to improve, but part from that, stage 1 is finished.

So now the search is on for some nice and functional ways to work out the next stage… and surely, were going to add a little motor somewhere again J

I show my plans to some dudes, but they didn’t understand that good lol

I think that’s cool.......

[andym85]

Here some pictures of the thing I made.

First of all I made 6 of the same plexiglass boomerangs.

I did this in plexi so you can see if something goes wrong.

Made the model in MDF offcourse, then I pasted the 6 pieces on , and held it to the copy-mill

Only this is how you get everything 100% the same.

After that I milled the MDF rings.

De linkse ring is van volkern.

Some more rings, and the plexi

This needs to be put together now, and then it’s finished.

Simple !

This “thing” I made, has a name… and I’m curious for the guy/girl who can guess what it’s called.

The first person may come over here to clean and dust my garage.

[andym85]

Maybe nobody know what I made …. Or nobody likes to clean.

The thing I made is called a “diaphragm”

A couple of words about the DIAFRAGMA. First I would like to say that I didn’t know how this was called too…

As I told before, I had it in my mind to make such a thing for years now. I never bothered to think how this was going to work exactly…this was al about mathematiques, and even in school I hated that crap.

But if you look at it know, it’s quite simple.

To explain it a bit easier, I let the top part off.

You can see 6 plexi boomerangs laying on top of each other. You can also see that on the tips there are some inbus-scews of M4, these are the hinge-points.

Here you can see him closed.

Here complete, with the cover on top.

This is the slide, where you open and close this thing with.

In the 6 slots there are imbus-screws. You can also see these are on the outside of the slot.

Now you see it close, and you see the screws go to the middle.

Now it’s closed.

You can see there is a hole in the middle, but that’s normal with this drawing. It never closes completely.

Some pictures from on the other side.

The meaning of this thing is, that I want it to stand behind the back of the rear seat. You may know that, in the beginning, I traded the normal rear seat for a rear seat with ski-hatch, to get the bass better into the interior.

Because I found this hole kind of BORING, I’m trying to put in a diafragma. Read again: TRYING !!

You also know the amplifier comes before that when it’s open, so I need to check and measure if I still have enough place to put it all.

I’m going to make everything out of other materials, about 18mm thick…

It also needs to open and close automatically, but that’s easy to sort out. The biggest problem is to ensure it doesn’t rattle while driving, but I may have a solution for that problem too…

Now about the hole (when everything is close up)… I think I’ve found a cool solution for that too.

I’m only hoping for one thing now… that I have enough place for this all…

[andym85]

These will be the final boomerangs for the diaphragm. I used anodized aluminum of 1.5mm thick.

This material is also used on the backside of the Focal Woofers.

I taped 6 plates on each other, and held it to the copy-mill. The uppermill is now the best tool to fnish these things off… hope the disc doens’t go in to tears now .

Here you can see the upperside of the boomerangs.

And this is how the backside looks. You’ll see right-away that I taped some self-adhesive black vilt on it.

I had to do this, so I couldn’t get any scratches on the aluminum when everything opens and closes.

Secondly this will prevent vibrating when I’m banging the install.

Cause the aluminum is only 1.5mm thick, I screwed in some screws with a bit of loctite on it. That way I’m sure it won’t fall apart.

The plexi boomerangs I made at first, landed in the rubbish bin…but they always seem to come back. How is that possible ?

[andym85]

In the meanwhile I finished the diaphragm. This is the aluminum plate of 4mm thick where it'll get on to.

With the 6 little pads that stick out on the side, I can tighten it completely.

The black ring you can see here, is MDF I painted. The ring I used from the first diaphragm I made.

This plate is also 4mm thick, and I put some more work into adjusting the slots where the screws will rest into.

The piece on the right side, will serve for the transmittion. Later I can u on this, what I like, and what's good.

You can also see I glued on a piece of vilt against the vibration.

Here you see the boomerangs sliding over eacht-other when it closes.

This is a cardboard ring of 2mm thick I cut out. Did this to catch the vibrations, and to adjust it all even better.

Here the upper ring of 4mm is mounted on. On the bottom of this ring, I also glued some vilt.

Here in close position.

The anodised aluminum in the middle will look great in my opinion. Very satisfied I've chosen this material.

This is the backside.

I must say this was easy for me to make.

The biggest problem was to make it tremble and vibration-free, and I did it.

When I open and close it all, you can feel the tention that's on it. I can adjust this delicately with the cardboard I used.

I screwed it all tight on a plate here on my table, and now I'm busy to adjust it subtle before adding the motor.

[andym85]

Here the little test I did. When you check it out, it's quite simple really.

The spring you see, pulls the diaphragm to close. On the lever, I put a bigger plate, so I can see how long I need to make my transmittion.

The more I pull the cable out, the more slowly it close and opens, and the less force the motor needs.

I really like the speed that it opens and close now.

I just need to make a descent piece of aluminum that will stand onto the motor.

Here a picture, I'm going to make a little movie, and post it offcourse.

Here a little movie of what I made of a "diaphragm"
