   We built a Plug-in Home Battery for the 99.7% of us without Powerwalls▲301

   Hi HN! I’m Cole Ashman, founder of Pila Energy. I’ve spent my career working on home energy systems—first as an engineer on Tesla’s Powerwall, where I focused on the Backup Gateway, Solar Inverter, and metering systems. More recently, I led Product at SPAN, where we built the Smart Electrical Panel and integrated with most major home solar, EV, and battery systems. Pila (https://pila.energy/) is a home battery that plugs into a standard wall outlet, provides smart backup power, energy shifting, and grid services. It’s more than a power bank—it’s a distributed energy system…

    SimBricks – Modular Full-System Simulation for HW-SW Systems▲67

    Hi HN, we are building SimBricks, an open-source simulation framework for heterogeneous systems, especially with custom hardware. SimBricks modularly combines existing simulators for machines, networks, and hardware, allowing you to build, test, and evaluate intricate complete systems in a virtual environment. Head over to the SimBricks website (https://simbricks.github.io/, also has a quick demo video) to learn more. We have pre-built docker images, and you can even immediately play around on codespaces. Concrete use-cases: - Evaluate HW accelerators, from early design with…
