Hi Tom
I am going to use 12v high force linear actuators (no driver and only top and bottom limit switches) I am going to attempt to make a adjustable indoor putting green (google zen putting green). I thought once built I could time the actuators under load and use the results to alter the program. To get an initial reading I am going to take a 12' x 6' ply board and set at varying heights(angles)then record the % relative to height.
It all sounded so simple when I had the idea!!!!!!!!!
Oh by the way I believe the Zen green cost's circa 40k I was looking under 2k to build.
Thanks
Andy
