I do have a few interesting developments to share. Marvin Simon (Gosh I hope that is the right name) sent me a pair of the Toshiba Shutter Glasses to try out on my circuit. Well, after a little unpacking and hooking up, I tried them out, and THEY WORK! They are a little bit more sensitive to the AC driving frequency than the SEGA glasses, but I fixed my small frequency shift problem, and they work like a charm. I suppose they would like to have more than 10 volt, but I saw no degradation of performance, and they are a zillion (Is that a word) times better than the SEGA version. Of course, they cost about twice as much, but the effect is more than twice as real. Marvin said that he knows of two other sets of glasses besides the SEGA ones. The Toshiba ones, and the Nintendo ones, I have seen pictures of them both, and they both look beter than the SEGA versions. However, they are probably not as durable, but that is the breaks. Befor4e you go emailing Marvin, let me tell you that I do not believe he is interested in selling single pieces. If you are indeed interested, let me know and I will see about where to get them, and how much they will be. All I can say is that I am a believer. Just don't go harassing Mr. Simon because I have a feeling that would strain my contact with him, and I need him to help me coordinate things. But the technology is aboard the design already. For those who want a driver now, I am just using Glen Harris's SEGA circuit driver. I use 10 volts out of a MAX 232 chip as the power source, with no problem, so get a perfboard and solder away. The circuit should cost about 5-10 bucks total. (Unless you have to buy a soldering iron) I will try to get in touch and find out about the supply of these glasses. Mr. Simon said there are many more Nintendo glasses then Toshiba ones, but I cannot see much difference from the pictures. He also said he had a friend who might be interested in selling single pieces, so I am off to reread my email and email him back. Got to go to work now. I have managed to make all my projects work with HC11 microcontrollers, so that I can hone my skills. I love the little chip.
