Very cool!  I had too look at it a few times to see what you were doing..  Maybe you can get someone with a CNC router when it comes time to make the full sized panel?
If I ever build a new CP - I want to do this  :)

Keep going!

That looks amazing Arroyo.  You really hand-routed that with a Dremel?  Most impressive.   :cheers:

Actually wasnít as bad as I thought it would be once I cut out the plastic on the Polyurethane, kept me from going outside the lines.  That Dremel work was probably about 30-45min, not too bad.

Very nice!!!  :applaud:

Thanks bud.

What I like about this is that the black areas stay completely black, and only the areas you want to glow do.  As with most of these things itís hard to photograph, but it is exactly the look I was going for.
I may have a line on a place that can laser etch a large area, Iím talking to them about doing a test with this control box, if all goes well I can ditch the Dremel work, Iím not much of an arts and crafts kind of guy.  :angry:

How large of an area do you need to laser etch?

Control panel width, so at least 17Ēx 35Ē.

If you can't find someone I might be able to pull that off. My laser has a pass through. The problem is that the adjustable height bed has play in it. I am working out a solution. Right now I can't index a spot move the piece further in and retain positioning.

Gotcha, let me know if you think you can pull it off.  Thanks for the offer!

Wow - haven't checked in here in a while... this is so cool.  The etching looks awesome and the whole thing is super clean.   :applaud:

My laser work area is 19 inches wide. The laser needs to swing at least an inch past the etching by an inch on each side to slow down and reverse direction. I can override that by slowing the laser head down. I am going to rig up a solid non moving base for the pass-through. I will know by the end of the weekend if this will work. My laser machine adjusts the Z height by moving the floor up and down. It is not rigid like a CNC Z axis. Once I have the floor immobilized I will be able to index and pass longer stock through. In theory I will be able to do your etching. I will keep you posted.

I have stabilized my Z axis. I think I can do that CP for you. Send me the appropriate files and I can give it a shot.

MikeA came through big time!

Laser etched the image:


Graphics applied:


Close up so you can see the contrast:


Unintended cool byproduct is a reflected image off the Acrylic that gives it a 3D look (didn't bother to clean up the dust sorry about that):


Assuming we can pull this off on a larger scale I'm running with this technique.

Thanks Mike!

That looks way better than I thought it would.
That is a very creative idea to merge laser etching with conventional artwork.  :notworthy:
I look forward to helping you kill some of those brain cells at Zapcon. I hope you like bourbon.

Well I guess I wasnít lying when I said I would post at a slow pace :-)

Spent a lot of time thinking about how I wanted to move forward and been doing a lot of experimenting.  Got some results I like and almost getting to the point of calling it done so I can move on to ya know building an actual arcade cabinet.

First thing was securing the screws into the mounting plate so I can swap out controllers.  Considered welding at one point, but itís complicated without using the same materials (i.e. all steel, oh and I donít own a welder might be a problem as wellÖhmmmmm), so instead started researching epoxies.  Seemed pretty good from what I read so decided to give it a shot.  First thing I read was that you get a stronger bond with a roughed up surface:



Busted out the J.B. Weld slow drying epoxy:



Mixed equal parts, used a piece of Acrylic to mix it together (wood stick probably would have been better), applied to the countersunk holes in the mounting plate and put the screws through till they were flush.  Noticed that I got some epoxy on the threads of the screw and quickly wiped off (would have been better to have used some plastic wrap to protect the threads).  Let it dry over 15 hours and:



Man this stuff is crazy strong.  It held up well to multiple attempts out over tightening the wing nuts Iím using

Side note: to quickly cut the Acrylic I used this tool that I picked up from Tap Plastics:



Instead of needing a special blade on a table saw, you just use this and a straight edge.  Make a few swipes till you get a decent depth, and then snap the remaining part over a straight ledge.  You get a very clean cut.


AnywayÖ.

Needed to drill out the hole in the center of the mounting plate because I needed to fit the addressable (WS2812) ring LED that I will be using to light up the center of the joysticks.  Made a 1 1/8Ē forester hole through wood as a guide, and then used a 1 1/8Ē hole saw to make the cut (I did this before the epoxy FWIW):





With that out of the way, I put the mounting plate back into the CP wood to finally be able to make a permanent install:



Iíve been using a white piece of paper behind the laser etched Acrylic (thanks again MikeA!), but needed something more permanent.  Picked up some Oracle 651 Matte White Vinyl:



Did what most guys do and used a sharp Exacto knife and followed the edges to cut it to size:





Cut out the etched Acrylic using the router mounted to the router table and used a flush trim bit to follow the wood outline:



I think I mentioned it before, but I love using this double sided adhesive (3M Scotch double sided mounting tape), itís crazy strong, so much that you only need just a little before it becomes almost impossible to pull it back apart.  It makes pattern cutting very easy though.

Next I put the etched acrylic on top:



Then applied the graphics between the two pieces of acrylic and used the same Exacto knife then to cutout the holes:



I forgot to mention that while I was routing the etched Acrylic I had to do two things.  I needed to shave off around 1/32Ē all around so that it would create a gap between the top layer acrylic and the wood layer:



You can see that ever so slight offset of the lower plastic from the top and bottom above, that where the edge lighting from the LEDís is accounted for so as to not bulge the T-Moulding. 

Also broke out the Map Gas Torch to make the edges optically clear for the LEDís (no I did not do it this way, the flame is far from the stuff around it) ;D



Next was putting the buttons in.  Th buttons act as a clamp for all of the layers and hold things together.  The only problem I had was getting the lighting I wanted on the buttons.  The side lighting from the LEDís lit up the buttons from the sides and washed out the colors from below.  Looks cool without the buttons in:



It seemed simple enough to line the hole with some Oracle 651 matte black vinyl to block the light.  It worked, however I got a tunnel problem on the buttons where the light wouldnít spread out to fill the edges:



I thought to use some mired vinyl to help, and it did but still not quite perfect:


 
It got better as I lowered the mirror vinyl down from being flush with the surface allowing the light to bounce more to the sides and reach the edges of the buttons.  Still not being satisfied I decided to break out a router bit Iíd been meaning try.

1/16Ē roundover to give a smooth edge to the button holes helped a lot (I tired many other things including black vinyl rings below the graphics, and all sorts of combos), this worked best:





I also used the roundover on the joystick hole so that it would have a smooth edge and not markup a clear dust washer.

More to comeÖÖÖ
