OSHWA

Most batteries are a real pain, proprietary and hard to recycle. Kirk Smith wants to power the world with the Flow Battery Research Collective by developing OS batteries for stationary storage! Hear all about in his talk on Day 1 of #OHS2026 and get your tickets right here: https://ticket.nodeforum.org/OHS26/

We are so excited to announce the talks and workshop schedule for #OHS2026!

Check out the lineup and see who is joining us from all over the world to talk open source hardware and maybe even register for one of the incredible workshops we'll have running on Day 2: https://2026.oshwa.org/schedule/
