Custom hacking case for my Raspberry Pi and Arduino

Update:

Just received my new Raspberry Pi and the Gertboard!  So here’s a picture of the new case with both installed.  Works way better than I could ever imagine!

One thing that makes me nervous is working on the RPI and Arduino with all the circuits exposed.  Well I had some acrylic plastic sitting around for the past few year and I had a spare 30 minutes this afternoon, so I cranked out a protyping platform/protective case.  The boards will mount inside so they are secure. All 4 sides are open so I can run wires in and out with no problems. On the very top I think I am going to mount the solderless breadboard. The top cover comes off by removing the 4 top nuts.   Maybe make it even easier by using wing-nuts or even barrel-nuts if I can find them. The whole thing measures 8×9 inches and the opening is a generous 2″ inches. Enough room for the raspberry pi, an Arduino mega 2560 and a relay board or motor controller.. Can even stack my pi face or Gert board. If there is any interest,  I took a lot of photos and could make an instructable with all the details.  Really easy and a quick afternoon project that looks great.  So if you would like to learn more, leave me a comment and let me know! image image image Pi Hard With a Vengeance using WordPress for Android

Destroyed the SD card socket in my Raspberry Pi.

When it rains,  it poors! For the first week, I have been chasing a bug on the Raspberry Pi. Where keystrokes from the USB keyboard are missing or are duplicated continouesly.  This bug is caused by low or no power on your USB hub. Since I have a 2 amp powered hub, I have tried changing devices looking for something that was shorted or power hungry that could be causing it.  The problem was intermittent, so I would have to wait for it to occur to try and solve it. Today it happened, so I replaced the keyboard (yet again) and started wiggling wires. I pulled too hard and yanked it from its case while the sd card was installed. The Raspberry Pi came out of the case ripping the Sd card mounts clips off.  It will no longer hold an sd card. Without an sd card it would not boot!
Found a quick fix. Took a micro sd to sd card adapter,  a little bit of epoxy and permanently mounted it in place. Put my sd card image on a new micro sd card,  inserted it and it booted right up!  Wonderful, but nothing attached to the hub would start.  No keyboard, no mouse or wifi.. Nothing!  Checked the power and it was fine, but even the LED would not come on. Tried it on a other computer.  Nothing. Ended up buying another one. Started right up!
Used it for a couple hours and not a single problem, not even the low USB power bug! My Raspberry Pi is working better than it did before, bug is gone, sd card works the same as it did before. True it is a smaller card (same 16 gigs), but it plugs into an adapter that is that used to hold the actual sd card.
Well that is part of the good news… Before I found the solution for both hardware problems, I had a moment of pure frustration and had given up for that split second. I feared it lost and ordered a second one. So in a few days it will be double the ‘fun’ when I receive a second raspberry pi.
I really am enjoying this little wonder !
