They usually don’t last more than 100 cycles. Therefore I wanted to explore the possibility of using 18650 cells to power my RC models instead. I while ago I got myself a cheap battery spot welder from China and a couple of genuine LG HG2 cells.

DIY motorized roller blind

This video shows my DIY Motorized roller curtain. It is driven by a stepper motor. An Arduino Nano is used to read IR signals from an old TV remote and control the roller curtain.
