FabGL Terminal Build

[Hendrik Magilsen]

I thought I would leave this note as a trail of breadcrumbs for anyone headed down the same path.   Mine is slightly different than the others in that I found the right interface card for a DB9 DTE interface.   This means you can use a straight through M-F cable to connect to the Altair-Duino.  No null modem required.

I also created a custom 3D printed case since the module size was a little different and I built it for a tighter constrained fit.  Published on Thingiverse and linked below.

Hi, 

I tried a little case like that for a while, then redesigned it so that I could have access to the micro SD Card ...

The 3D printer files are online at:  https://pinshape.com/items/115750-3d-printed-lilygo-ttgo-vga32-v14-controller-ps2-case  

BTW, it doesn't need vents ... the module doesn't even get wam.

The case was more of an experiment in a different approach on Tinkercad. 

I find that app useful, but often frustrating manipulating 3D objects on a 2D screen as the shape gets more complex.  So my next attempt may be in OpenSCAD.  It's a decent reason to learn something new.  In any case, I'm pretty happy with the build as I learned stuff along the way, even if it doesn't need ventilation.

My post was primarily intended to leave a few trail markers for others, since when I started on this path I was given a great hint, but I had lots of questions.  Info wasn't that easy to find, or just old.

I'm sure there's still more for me to figure out and tweak as I'm using it 'out of the box', but maybe this makes it a bit easier for the next guy.
