Project: Alien Hospital

[_ferry_]

No, i haven't tried it.
I'll try to order it when buying stuff at the airbrush shop.
I have some airbrush foil as well, i could have used that as well.

Well, in fact it was the paint, not the tape, since the paint held well on other projects.

Kick

Case is painted now, working on the 4 touch sensitive display button's. But they work like hell
A single button was working fine, as i showed in a movie. But with 4 of them i'm getting too much inference, and they can hardly detect my finger.
So i'm planning some re-design on the q-touch circuit after reading the application notes. Like a separate power supply, shielding, keeping the wires away from the leds and 40x 10nF GND coupling capacitors on the common lines of the led's if necessary since led's can give some induction as well. Also some experiments with different sensor's. I might mill a hole in the acrylic to put a sensor in, instead of a sensor around the led's (which is further away from my finger)

I thought it would be easy Hehe Since 1 button was working fine. Well, i think it's worth the result.

Okay, here are the pics from yesterday. Haven't made a lot of progress today, since i lost some parts i needed to rebuild the touch sensors. But i ordered them. Thanks to AC Ryan i hope to receive the aluminum for the main case soon! The base 'll be anodized black, with a RVS or aluminum operation desk. Actually i'm looking for metal plates which has been circular brushed/polished:

Oh well, the case:

I polished 4 aluminum strips, to finish the edges of this case.

Test-fit.

Rear side of the case. I gave the grills a slightly weathered look. I decided to not giving it a fake-metal look, since fake metal with real metal will look bad.

Mount of the lcd to the base. When releasing the small screw i'm able to adjust the angle of the lcd panel.

Close up, a gray base with some red and black tints.

Front panel

Getting started with the other 2 LED displays.

Done, including a test-fit-sheet made of styrene.

Test fit. Looks cool right? (even when 3 are facing upside down )

Milling the aluminum frame/shield. Lines are for reference, i milled it by calculating the length of each line including the mill diameter

I kept some connections to keep his strength while milling. i had to sand the edges anyway. Looks how straight, could have been lasercutted hehe. Imaging yourself trying to do it by hand, to get a straight looking front panel...

And even the handcutted front panel fits fine.

The fit exactly in the holes i´ve made, so they won´t fall out themselves But it's not only a mounting frame, it should protect the q-touch sensor area against EMI/conductivity from the microcontrollers and LCD panel. Since i had some trouble with fals triggering. But i'm working on that right now.

Together with his PCB.

Dude, that looks so cool! I can't believe what you've done with some of these ideas.

Way cool work. I can't wait to see the whole thing in action!!

The leds look really cool, I hope you get them to work I really want to see this project when you finished it, so I hope you will be on a NKCM or tBCL or something then :p

Thanks

The led's are working fine, i can show any symbol i want to. But the buttons are the problem. Well, it should be possible to get them working. I've ordered various capacitors to adjust their sensitivity. Hope to show this pc too, don't know if i'm going to finish it in 2008.

Congrats with the frontpage article, you deserve it

Noticed that! Very nice nice picture too.
