Let me introduce PWM Record/Stop Controller for BMMCC by RADIOPROEKTOR. This project was started long time ago in parallel with unfinished BMMCC handle grip. Controller have only one simple latching button switch and controls camera Record/Stop. Button switch is very comfortable and very soft to press. It uses PWM interface and compatible only with BMMCC (BMMSC doesn't have PWM interface). It uses 3.5mm TRS socket connection, so you can take any common 3.5mm TRS jack cable and plug it to BMMCC Expansion Box Module by RADIOPROEKTOR.
I successfully tested prototype over all this time and hope in near months i'll be ready to start small batch manufacture.
Controller body fits to common 15mm rod clamp, so you can use it with any existing 15mm rod clamp accessories and mount it anywhere on your rig.
Also here are some early attempts to pair it with SmallRig handle. Usable, but not perfect. Button switch feels slightly far from finger and in some hand positions not too comfortable to press:
So i ended up with controller mounted like this. Very easy to press by left hand in same position as you adjust focus of the lens. Also when controller mounted like this you don't need to unplug it every time when you attach and detach side handle.
