Alpine Carputer - Part 13


I am originally posting this project on the Overclockers Australia (OCAU) forums) in this thread:
Specific Hardware Topics > Modding > Alpine Caputer. This is post #70.

This project made the front page of OCAU! (direct link)



After hearing that MSG LED is actually NOT for network connections and is almost identical to PWR LED (thanks HellTaxi), I dug this out for a test:







BUT IT DIDN'T WORK!!! So, not willing to just accept that, I got this one out and gave it a shot:







Both of them are pretty old and were pulled out of a case that was scrapped a long time ago. This is why I tried the second one, just in case the first one had died somehow. Anyway, point is: THE SECOND ONE WORKED!!! So now I can get on with the power LED idea :) Well... after I get the LED... I'll have to come back to this later.

Now, even though I had the 2 brass motherboard stand-offs held firm by the metallic cement, I noticed that when I the amp casing upside down, the board comes loose down the bottom so I have to do something about that! My first thought was these:







I don't want to add too much height though so out with the knife aaaand:







This doesn't add any height whatsoever but still holds it down. Now, to attatch it, out comes Selleys Liquid Nails:







Bonding the modified stand-offs to the electrical-tape-covered surface probably wouldn't be a good idea so I put the motherboard into position and secured it down with the existing stand-offs. After this, I grabbed a pacer (from my old school supplies, much like my Coca Cola ruler... Product placement anybody??) and extended the lead so that I could make a mark through bottom mounting holes. I then went over it with Sharpie which seems to make it reflect a bit better under light:







I then cut the tape back around these marks:







The mounts went into the bottom mounts of the board:







A little bit of liquid nails, pressed it down and tried to get the motherboard off. Unfortunately, it hadn't quite set yet and the stand-offs came off with the board BUT this gave me a good look at the positioning of the holes I had cut. They weren't right! They were too small and a bit off so I made them a bit bigger:







And this is how they sit now:







So, they're still not perfect. They sit slightly on the edge of the holes in the electrical tape but the most contact between the stand-offs and amp housing is in middle of the holes so I'm not worried about it pulling the electrical tape now.

It's been setting overnight but apparently Liquid Nails is supposed to take 24hrs to a few days to set fully so I haven't put the motherboard back on yet.
