trigger support for camera time lapse

I used an old canon camera with Canon Hack Development Kit (CHDK) (very easy and friendly wiki). made a modified micro USB cable with 5v line attached to an end stop trigger, fixed on attached support results are amazing for such and easy and cheap setup.

remarks: I am powering the camera with direct power from usb by https://www.aliexpress.com/item/Power-USB-Cable-DC-Coupler-DR-40-DR40-NB-6L-for-Canon-Powershot-Cameras-ELPH-500/32775078023.html?spm=a2g0s.9042311.0
