Hi,
I present my DIY G-Seat simulator.
It based on G-Seat system. The purpose is to generate G-force on pilote with almost no movement.
The bucket seat is slice in 3 parts. The backrest is a the only fixed part, seat and the top of the seat (behind the shoulder) are mobile parts.
Bottom of seat transcribe longitudinal G-force, top of the seat combine longitudinal/lateral G-force.
The system is actuated by 3 DC motors of 150 W. The electronic part is composed by Aduino Uno with 3 H-bridges (MotoMonsterShield).
