No idea how you would build a power bank that speaks USB-C? This talk is for you! - Beginner friendly, but with all the technical details! - Started from zero in electronics and hardware design - I want to motivate you to do a project without prior knowledge for fun and learning! - Ended up with a functional 250Wh USB-C PD power bank with a custom circuit board inside a can of *Volt Power Cola*. No idea how you would build a power bank that speaks USB-C? This talk is for you! I started the project with no hardware design experience and close to zero knowledge about electronics. My main goal was **learning something new while having fun**, so I picked a project that would be challenging but achievable at the same time. I want to motivate you to do the same, and I'll share what I've learned along the way. I had to learn about basic electricity and electronics, batteries, designing circuit boards, different soldering techniques, spot welding, reading chinese datasheets, 3D printing, CNC milling, the USB PowerDelivery protocol, the I²C protocol, shrinkwrapping a design foil onto a soda can, safety measures, and so much more. The electronics are based on an IP5328P chip. You'll learn about the many challenges and how I solved them. And of course how to build a power bank. https://creativecommons.org/licenses/by-sa/4.0/ about this event: https://talks.mrmcd.net/2024/talk/FXW9UX/
