A local pastor in the area builds electric train sets for children who he feels could benefit from the joy of playing with the trains. He contacted us asking if we could design a way for a boy with only head movement to control the train. One of my good friends Mel Torrie is owner of an amazing company that builds autonomous vehicles and robotic devices. Autonomous Solutions has some engineers that volunteer their time to create projects using their electrical and engineering skills. They have put together a local chapter of volunteers under the Tetra Society and complete projects in Utah and the intermountain west.
To allow control of the train, they created a voltage regulated box that was controlled by sipping and puffing into a tube. One puff would move the train forward with a range of 10 puffs to control the desired speed . A sip in the tube would slow the train down and/or put the train in reverse. Tetra put a story about it in their publication the GIZMO.
