I have a lots of powerfull DC motors lying around ,and had made 180degre's servo out of them (car windscreen wiper motor) , I was wondering is there a fast and accurate way to make then into continues rotation servos ?
tried homemade solution whith opto-sensors and a disc whith hand cut groves , didnt turnout acurate at all . Next on my list is trying an encoder from old printer , but i realy dont have the time , to make test and so on , so I wont you to try it .
