Rectangle2 is a side project I have been working on for the past couple of years. It is a small power management device with modular design. It has two configurable USB-C PD ports supporting up to 60W of power. There is a third USB-C port supporting connection to a host providing remote control. Additionally, there are two barrel jacks. One barrel jack is a power input supporting solar panels, and another barrel jack is a configurable power output. A small display with navigation buttons provides an interface to monitor the metrics and configure the device.
In this talk, I will walk you through the design iterations and challenges I encountered. From major issues - such as balancing modular design, cost, and usability - to smaller details, like selecting the right mounting screws, I’ll share key lessons learned along the way.
*About Teardown*
Teardown is a yearly event hosted by Crowd Supply that draws hackers, makers, and engineers from across the US (and the world) to meet together in Portland, Oregon. Teardown is about the practice of hardware: prototyping, manufacturing, testing, disassembling, and circumventing, all while having fun. Teardown attendees can expect lively talks, demos, art installations, hands-on workshops, fiendish puzzles, and lots of good food. Check it out! crowdsupply.com/teardown
