This gadget is really helpful to rec and stop video or taking a photo handsfree. I've adapted Bluetooth Shutter Switch into a foot switch box. So you may Rec and pause (or stop) your video or take a photo handsfree. You need only below items some cables, rocker switch (can be harwest easily from old electronics) and a battery holder. https://www.amazon.com/dp/B08L... https://www.amazon.com/dp/B0BJ... Kevin NGAI
