Honey I Shrunk the Computer

My 1/3 scale mac is done! 

The Outside

I made the case using white 3m Sintra (a sheet of pvc, easy to cut and sand) using an x-acto knife, files and sandpaper for the bezels. The sides bottom and front were formed into one part of the case with the top and back as the second piece.

HDMI, two usb ports, ethernet ports.

The Inside

The monitor is a 3.5" composite monitor similar to this one. It's held in with two brackets at the bottom and a few velcro tabs at the top.

The rest of the hardware is attached to a bracket that is easily removed with a few screws.

On the left is the Raspberry Pi. To the right of that is a Four port powered usb hub similar to this, along with it's AC/DC adapter. Two of the USB ports are facing out and two facing in. One of the inside ports holds the wifi dongle and the other will hold the bluetooth dongle when it arrives. On the very top is a 2 port 2.4 amp usb charger that is powering the Pi and the monitor. A note on the monitor, even though it's supposed to use 12 volts, the 5 volt charger is powering it quite nicely but your results may vary :)

To make everything fit I had to make a few modifications.

On the Pi, I had to cut the SD card down almost flush with the edge of the Raspberry Pi board. I also had to cut away quite a bit of the USB cable on the top to get it to bend below the top of my case. The last thing I had to do was to solder wires directly to the Pi board to bypass the power connector. 

I tried to find some small wire connectors instead of having to twist and tape everything but no such luck :(

    What kind of resolution do you have for the monitor? As far as the disk images go try this, when Mini vMac is launched, it can automatically mount disk images named "disk1.dsk", "disk2.dsk", up to "disk6.dsk". See if that helps. You mentioned install disks. Do you have a working hard drive image or are you trying to start from scratch? The .img file I'm using was originally set up on my MacBook so I haven't tried using the drag method on the pi. I'll try it tonight when I get home to see if I have the same result as you.

    Hi John,

    Thanks so much for the reply. The monitor has given me some trouble so that may be a separate issue (I couldn't get the Pi to boot higher than 592 x 448 despite it being a 2560x1440 monitor) -- but I will try your disk1.dsk - disk6.dsk approach tonight as I am starting from scratch on the Pi without a hard drive image.

    I also find your install/setup approach appealing - are you saying you set up an img file with Mini vMac on your MacBook and then just plopped that img onto the pi? That seems like it could potentially be much easier.

    Thanks again -

    That is an odd resolution! Are you using Raspbian on the Pi? Also yes on the setup I set it up on my Laptop and then simply transferred it to the Pi with a USB drive.
