This is just my personal list of TODO-Notes on this project. Maybe there is something for you to do as well :)
- Add a reverse polarity protection to the board
- Add holes to the board to attach a plexiglass cover
- Embed the USB Blaster directly on the board and remove the power connector. The board should only be powered via USB. See the following link for more information: Blog-Post
- Provide a firmware for the possible onboard USB Blaster
- write own GUI application to draw circuits and call Quartus in the background for synthesis and upload (alternatively finalise the overlay). This UI needs to be better than the Quartus Software.
- Finally make the "Overlay" work!
