Primarily working with miniatures, but also exploring solar, steam, and thermoelectricity, I stumbled upon the YouTube channel of Greek maker JohnnyQ90 and felt compelled to share his projects with you.

The parts spread at the beginning makes me imagine the tools I want to fabricate from the spare bits and pieces I’ve collected over the years.
Fascinating stuff. You can see all of JohnnyQ90’s videos – and subscribe to his channel – here.
