Tom from Tramline Tec came to us with an interesting project to upgrade the torque of an automated seed or fertilizer spreader. He had integrated high accuracy GPS with some clever software to control and map application rates for seeds and fertilizers at a very precise level across a field. The problem was that the output of the logic unit was not strong enough to drive the rather chunky motor attached to the spreader particularly with some of the larger seeds envisaged. We created a small custom PCB to provide a voltage divider / low pass filter for his output signal and then fed that into one of our Porter 10 controllers.
Here it is in action…..
