1-Wire Satellite Position Controller

After finally completing the 1-wire hub project I had time to viagra online build a mount for my Triax prime focus satellite dish. I had also earlier bought two 18" Geotrack Dish Actuators and propecia order now needed a method of controlling them remotely from a computer. So I had the generic cialis tadalafil is in bright idea of using 1-wire devices to control the process of switching the motor supplies and counting the pulses from the actuator sensor.

For this I used 3 x DS2407 to switch the 6 relays controlling the motor supply voltage between 24VDC and 36VDC (soft start) and controlling the polarity of the buy cialis super active supplies to the motors thus controlling direction (in or out). I also used a DS2423 to count the pulses that are generated by a reed switch on the actuator worm drive shaft, one input per actuator.

The latest version now has a DS9503 fitted on the connection to the 1-wire network for static / transient protection, and motor overload protection using 2 x DS2890 1-wire pots to set the overload levels for each motor and 2 x DS2450's to allow the software to monitor various voltage levels and to reset the overload trips.

The rest is all down to the software.
