A Little History:Dr.-Ing. René Görlich developed the Gemini-1 controller and released the first version back in November of 2000. That system went through 4 major versions of the PCB and also many version of the firmware up through Level 4 V1.05 You can see this development at the bottom of Dr.-Ing. René Görlich site, and the different PCB versions here. What most people do not know is that the Gemini-1 unit during the initial development was tested first in Australia. The Level 4 version of the Eprom for Gemini-1 was also tested in Australia by René himself. He traveled to the outback to do much of the testing of the Level 4 version of the Gemini-1.
This system was designed and developed by Dr René Görlich as a bet, that he could do it for under 2K$. A direct quote from René: "Roland Christen stated in a news group that nobody would be able to design a telescope control servo system at a price below 2k$. I did, but to a certain degree I've have to admit he was right to a certain degree. Only dedicated users, companions, testers like you made it possible to put it on the astronomy market at much lower cost."
I think, but am not sure, that at the time he was using one of Losmandy's digital drive systems on his mount. I think that Scott Losmandy and Larry Myers was contacted for funding, and Aveox was used for the servo part of the Gemini and also to lay out the PCB boards.
Well as electronic do, they change and advance. Most of the time electronic parts do not stay in production for more than 10 years at maximum. This happened with the Gemini and severely hampered production on new units starting in 2008.
At the time Dr.-Ing. René Görlich, was not in a position to start on the Gemini-2 because of his work as a Dean at Technische Universität Berlin (he supervised 45 professors and 1500 students over a 5 year period, and still taught also, and still teaches but is no longer in the position of Dean.) So the development of a replacement had to wait, even though it was being discussed heavily.
I think that Dr.-Ing. René Görlich, and Scott Losmandy started the actual development of the Gemini-2 in 2009, as I was contacted in June of 2010 and asked if I would like to be a beta tester and could I recommend others to be beta testers also. I said Yes, and recommended two others to be beta testers, because of there work in developing the new ASCOM Gemini.net driver.
So the beta test began, and rumors were going left and right that there might be a new Gemini controller. Well about 6 months after the beta test began, one of the beta testers put pictures of the Gemini-2 on a web page. He never expected anyone to see it, but as we all know, if it is on the web, it is not secret. The news was spread in the Gemini users group. Scott started being hounded for units. He sold some units, and asked that the ones he sold them too, be made part of the beta test program. I am really not sure when he started selling them without people being in the beta test program, but I think it was around Sept or Oct of 2010.
How others have contributed:
As you can see, the Gemini and the Gemini-2 have been developed by many people, but Dr.-Ing. René Görlich is the spearhead, the founder, and the driving force behind them both. Many years ago he developed the G1 and it has provided many an astronomer great and accurate service. We are hoping that the Gemini-2 builds on that reputation.
The Gemini-2 keeps developing. There has been so many menus and improvements that René has added due to the suggestions posted by the users on the Gemini-II Users Group. It has come a long way, and René still has many more upgrades and additions planned for it. As one user has said, about the only thing it won't do after a long night of observing is make you a cup of coffee.
I know that many others have also contributed with there suggestions into the development of the Gemini-2, and I really hope I have not missed any major players. If I have please let me know.
Thank You ALL!!!!.
