If you feel up for a real challenge, you could write an INDI driver for the Velleman K8055 series of boards.
This would be a highly non-trivial undertaking but one which would win you kudos with a wide selection of the amateur community. People have been asking for one for years.
At the moment domes with a Velleman controller, mine included, can use only the LesveDome ASCOM controller. The problems with LesveDome is that the source code is unavailable, it is Windows only, and is ASCOM instead of the much more portable INDI.
Yesterday I purchased a Velleman WPI110N (the latest release of the K8055 series) with a view to seeing whether I can persuade it to play ball without having to perform potentially dangerous tests on a live dome.
