      Hi All
   I have three long period homemade sensors with balancing motors, I check their position voltage manually every 2-3 days and if they are to far off center I send a 5 vt  + or - signal to the sensor's low rpm(1 rpm) balancing motor for a few seconds to send it back towards zero. I would like to do this automatically. I could do this with a microprocessor but I thought it might be done with something more simple like some gates,switches and possibly 555 timers. I have not tried to create a 555 timing circuit with such a inballanced duty cycle ( on for ~ 1/2 to 1 sec and off for ~24 hrs). Any thoughts?
