weareborg Posted September 3, 2004 Report Share Posted September 3, 2004 Hi allI wonder if any one can help me out here. ???I am trying to locate some really old serial mice. THe type I am looking for must have 2 pairs of detectors/receivers on each axis, and not just 1 pair (which are the type I keep coming across).The reason being, is that they will be connected to the 2 axis of my homemade telescope, and with the Interface that I have built, they will act as rotational encoders and will be able to tell me where in the sky the telescope is pointing. Also known as Digital Setting Circles.The 2 pairs of sensors on each axis are needed so that they can work in quadrature mode. ie one channel leads the other channel by 90 degrees.Any body out there who has some lying around and they want to get rid off, please let me know.CheersAndy Quote Link to comment Share on other sites More sharing options...
Dazza Posted September 3, 2004 Report Share Posted September 3, 2004 I have one, and could probably get more, but it's a long way to send them to you from Australia. There are plenty of opportunity shops here were I live. These are organisations like guide dogs and Red Cross, that set up shops to sell donated clothing white goods etc. It's amazing what you can buy their to recycle for electronics, and your money goes to charity :). Maybe there are places like this where you are. Quote Link to comment Share on other sites More sharing options...
