Another great DIY 6DOF platform was made by Markus from Germany.
Its a 6DOF Motion Platform with DIY DC motors actuators . It uses Ians BFF actuator design with major improvements, Ians BFF 6DOF Motion software Driver, Sabertooth 2x25 and Thanos AMC1280USB 6DOF extension board to drive the platform. The platform provides enough power to lift up 200-300kg which will be good for a good motion platform.
The linear actuators are based on Ian's design here: http://bffsimulation.com/linear-act.php
