This project solves a problem of remote controling non-motorized lens. Three camera lens rings: focus, aperture and zoom rings are moved by mini stepper motors. The motors are controlled by a teensy controler with ethernet module. OSC protocol is used for communication with the controller over ethernet cat5. The controler receives motor position and sends back feedback OSC messages: uptime and current stepper position. Various existing applications can be used for remote control i.e Isadora, TouchOSC, Qlab, MaxMSP etc.
- teensy 4.0
- ethernet wiz5500 module
- 3x DRV8823 stepper driver
- 3x (focus, zoom, aperture) mini stepper motors GM1527-10
- rotary encoder with RGB led from Saimon - Hardware V2.1
- red: no ethernet connection or damaged ethernet module (the motors will respond to pots)
- blue: ethernet connection, blinks purple while sending OSC report
- green: receiving OSC
- orange: resetting steppers to home position
- yellow: initialsing hardware
- white: identify unit
All comopnents are soldered on custom designed PCB. There are few SMD capacitors, MAX811 reset IC, teensy 4.0 and DRV 8823 boards.
- Drakon - visual language for flowcahrts
- Atom - An amazing text editor
