Timelapse on a Budget ~ 100 €

I always loved the look of Timelapse videos, as I found the ability to squeeze several hours of time into a short video interesting and beautiful at the same time. Until some time ago, timelapse photography would require the use of DSLR, mirrorless or some other camera, either with a built-in method to shoot an image every couple of seconds, or with an external intervalometer. It would also require a sturdy tripod, and for longer time lapses some way to extend and enhance the power supply, as the batteries in DSLRs or EVIL cameras are good for a couple of hundred shots on one charge (around 500 in the best case) and the entry-level cameras made by most manufacturers normally don’t have provisions for powering them externally while shooting.
