Uses so far:

2018 FIFA World Cup Football BBC Russia (TV) - Used to control a ProSup Tango slider rail in the main BBC studio above Gary Lineker.

Life (Film) - This has been used for many weeks on "Life" controlling a roll ring, and slaved rolling monitor.


GRAPHICAL POSITION DISPLAY:  The LCD display grapically  shows motor position (if end stops are both set),  joystick demand,  and motor speed  for clear user feedback.

DISPLAY / LEDS:   Ring LEDs display approximate speed,  & direction of desired motion.  The LCD can also display  general parameters, and user settings.

SETTING END LIMITS: You can unplug the stick, & the drive will keep its limits - useful for changing batteries on the stick. The stick displays active end stops both on the LCD and with  LEDs.

ACCELERATION / BRAKING:  Both rates are separately adjustable on the stick.

SHOT-BOX POSITION MEMORY: There are 4 available "1-touch" motor position memories. The motor will drive to the selected position with  user-selectable ramp-up, ramp-down and speed settings.

DRIVE UNIT:  The motor drive unit is extremely compact, measuring approx  82 x 68 x 35mm (3.2" x 2.7 "x 1.4")

OPTIONS: Currently the "standard" kit has a 10m RS-485 control cable - Options include RF link, battery backup for the drive (to keep endstops, position etc for extended period), batteries for the control stick (for RF use) etc.

PLANNED ADDITIONS: Time-lapse with shutter trigger, Bluetooth connectivity
