A Few Tools for Re-Imagining the Future

Ashley Jan Lewis

Afrofuturism of the Science fiction writer Octavia E Butler
Octavia E Butler wrote the Parable of the Sower book series which predicted our current situation
Octavia Rules from predicting the future.
- Learn from the past
- Respect the law of consequence
- Be aware of you perspective
- Count on surprises
Predicting the future can be used to avoid hazards

How Frustration Led to Delft Open Hardware

Jerry De Vos

Jerry tell how we went to college to learn to build open hardware and found his university required him sign an intellectual property agreement assigning all his work to the university which is contradictory to making open hardware.

How to Enable Anyone to Build their Own Renewable Energy System

Kathrin Weihe & Michel Langhammer

Building Blocks for DC Energy Systems | The Libre Solar Project
Can handle up to 16 cells on the battery management systems
Moving to the Zephyr IDE
BMS can configure all set points for cell voltages between 1 to 5 V.
Wind turbines (2.4 m) generate a voltage that is too high for the Battery Management System (BMS) so a DC/DC would be needed to transform the generator voltage to an input voltage range that he BMS can handle.
