I then decided to design this new circuit, this time very simple, which doesn't need any microcontroller, is connected to an IR remote (mine is for Olympus Camedia bridge camera, but you can find similar ones for almost any compact and DSLR camera) and it includes a simple voltage regulator only to supply the IR remote control. Digital camera should need its own PSU (or battery, but it should be a very powerful one for a timelapse). So the TIRR was born!
Step 1: Intro
Step 2: The remote
Step 3: Choose the box
For my timelapse circuit I've decided that one of these transparent boxes from Muji could be very appropriate. The shop has various sizes of these containers, and I've found a model which is the right size to keep 4 AA batteries inside, plus a little rectangular circuit.
