How did you come to make this project???
Well I love to build computers. So I tried to make a single board computer with a parallax propeller.... and it never worked. The pcb was kinda scrapped and the project abandoned. Later, again working on an FPGA computer, I didn't want to make the FPGA do graphics, so I thought "Hey, why not use that old, scrapped and otherwise useless board to generate graphics?" Now, the remains of an old single board computer became my first version of this project! I never knew I could love a design so much, and I made another graphics card. A cleaner version. Now I am making them using boards from OSH Park! All thanks to a scrapped single board computer.
Where is the project now?
Pretty much got everything working. Will still improve it more sometime, so its still an ongoing project.
To come once updated:
- Supports 3.3v and 5v UART
- supports NTSC and VGA video output
- Support for sprite rendering
- RAM on card can be modified for quick, repeated draws of complex objects
- Can be an arduino shield
- Any suggestions?
My latest version is the NGT20, an advanced and refined product with all the latest bells and whistles.
Now available on Tindie here!
It's best to see the Documentation Portal instead.

NGT15 Datasheet (WIP) (Outdated design! Why is this here?)
Please help me improve my datasheets! I would greatly appreciate feedback on these documents.
