LM2587S Step up case

thingiverse

I bought a battery vacuum cleaner, but unfortunately after two weeks I could not find the charging adapter.  The voltage specified for the power supply is 26V. The only power supply I could find had 24V. However, the 24V was not enough to charge the vacuum cleaner. It only became very warm. But then I had the idea to build a step-up or LM2587S step-up converter with adjustable voltage in my hobby cellar.   Link to step by step guide: https://nerd-corner.com/de/step-up-modul-dc-dc-lm2587s
