For about $65, I was able to build a modified version of the K8DAV U-100 Rotor controller, and now my Elk antenna turns automatically and follows the satellites during each pass.\n\nMy particular rotor is the Alliance HIR, which is electrically the same as the U-83 and the U-98, and which I bought for $25. The K8DAV controller for these rotors is the same as the one for the U-100, except for the value of the motor start capacitor. The U-110 takes the same capacitor as the U-100.\n\nThis was a fun weekend project and a very useful addition to my satellite setup. I picked up two of the most expensive parts, the transfomers, for $1 each at the Goodwill store, in the basket of assorted wall-warts in the electronics section (bring a VOM and test the wall-wart before purchasing). You could also use the transformer and capacitor from the rotor's original controller, but I was afraid to cannibalize it without being sure I could get the new one to work.\n\nOtherwise, the project box was $18, the Basic Stamp board was about $20, and the solid state relays were $7 each on eBay. All other parts were inexpensive.\n\nFull plans, files, photos, and links for parts at:\nhttp://www.k8dav.com/ and\nhttp://www.cnyara.com/index.php?name=Content&pid=18&page=1\n\n73, Bill NZ5N\n\n\n\n \n", "attachments": [] }
