Title: Show HN: We built an open USB-C Power Delivery analyzer and programmable sink Hi HN! We’re Arbi, Marco, and Rob, and we built Dr. PD to make USB-C power problems easier to understand. It sits between a power source and device, captures and decodes their USB-PD negotiation, and correlates it with voltage and current measurements. It can also act as a programmable sink, with support for fixed supplies, PPS, AVS, and USB-PD 3.2 EPR up to 240 W. Commercial USB-PD analyzers are often priced beyond the reach of hobbyists and independent designers. We are on a mission to make high-quality…

We built a multi-port USB-C PD3.2 system that treats power delivery as a software-defined problem rather than fixed-function silicon. This started as our internal R&D platform while developing a consumer charger. We were uncomfortable with the typical “the FAE handles the firmware, you just build the hardware” model that dominates the PD ecosystem. In that model, key behavior lives in vendor-controlled binaries, arbitration rules are opaque, and meaningful customization is either discouraged or impossible. We wanted full ownership of the system — from power stage to protocol logic — and we…

I am not sure if this is fits the HN community, but I am posting it here if people are interested. This is the current iteration of the car: http://i.imgur.com/ko8YBh.jpg Details: I wrote a simple android app that streams the accelerometer data from the phone to the pi over a simple socket. The pi then uses this data to drive the DC motor and the servo motor. Tilting the phone to control the car feels very natural. In this[0] pic you can see the wifi dongle I've used. I am using Adafruit Occidental v0.2[1] as my OS because it has support for my wifi dongle. It also makes some hardware…
