M5StickC camera hot shoe mount/holder by Dahlers1

Last crawled date: 3 years ago

I designed a hot shoe mount for the M5Stick C Plus that is minimalist but holds the unit tight and secure, even on mobile cameras.
This holder works for M5Stick C and M5Stick C Plus. It uses the regular watch belt mounting holes in the M5STick C.
It uses a standard 3/8" thread (often used on microphone stands). It should be compatible (no guarantee) so one could also use a 3/8" knurled nut instead for tightening.
Parts on the images printed in black PLA on an Ender 3 v2.
Assembly
Print the parts
Put the knurled nut on the thread
Use superglue to permanently connect holder and thread (press fit also works fine for the first test)
Software
I am using Tally Arbiter to create tally lights with M5Stick C Plus. I am using OBS Studio as broadcasting software. It works great.
Of course for live use you need to attache a power supply or a power bank to the M5StickC. The internal battery only last for about an hour.
Code for the M5Stick C
C code for the Tally Arbiter-M5Stick C Listener on GitHub
By default the internal red LED lights up when in program mode (red screen). To change this to an external LED just change
const byte led_program = 26;
const int led_preview = 25;
The red LED is than connected between G26 and 5V (as seen in the picture).
