Built a Mini LISA, it was a bigger project than I anticipated.

Ever since I saw the new LISA documentary I've been consumed with both getting a real LISA and building a micro LISA both of which were depicted in the film.

I've had my original Lisa up and running for a year now and finally I've gotten around to getting the micro LISA going.

Thanks to Paul Griggs for the 3-D printing of the case!

I would've purchased one, but the person who first made them apparently stopped selling and supporting them some years ago. The screen is no longer available that he used, and there are no published SD images that I could find.

Here's some details if you're interested. The case files for printing can be found in several places on the Internet, including thingaverse. Link below.

The screen I'm using is better than the original design because this screen is 640 x 480 which allows almost the entire LISA screen to be displayed.

It took me a while to get the emulator up and running on my raspberry pi I ended up using an older version, which seems to run better on the raspberry pi.

It uses a pi version 2b, which is pretty inexpensive.

I will be posting an image of the SD card with full operating system and LISAem emulator configured along with the drivers for the screen in a day or two.

I'm open to suggestions.

Let me know if you have any questions!

Materials:

This is a difficult model to print. Mine was printed using the classic Mac PLA color filament.

The .stl was made for a different LCD screen that has a Lower resolution and is no longer available. This is a great screen, but don't use a GPIO cable longer than 4 inches or bizarrely it might damage it. The front case mounting holes will not lineup so I had to hot glue it in.

Neat!

I have possession of Ray's Mini Lisa that he talked about in the documentary.  The software works fine but the little Adafruit screen lights up but does not display anything.  I don't know if Ray ever had it working himself.  The drivers for the screen are obsolete.

This display is only quarter VGA, the one that OP used is full VGA.  I was thinking of ripping out the Adafruit screen and replacing it with this VGA newer one, or should I not do that as this a historical LisaEm artifact. 

I followed Ray's emulator project for a long time, and when the Raspberry Pi first came out in 2012, I was the first one to build LisaEm on the Pi.  It took about 96 hours to compile on the the original Pi and I spent weeks getting it working.  This is how I first met Ray working on this.

Wow! VERY cool!

That reminds me I still need to make the SD card image file!
