SHTTTRRR is the Simplest Intervalometer You Can Think About

Camera hacker Glitchmaker built the most simple and essential intervalometer you can make. Connected to a Canon camera, you switch it on and press a button two times, with the desired amount of time in between. That’s all.

The project is documented on Hackaday, and was spotted by PetaPixel. The video above shows the device in action.
