Discourse Discover: Building in the Physical World
Three Discourse communities where engineers and tinkerers build real hardware together.
Welcome to the Discover Roundup. Every month, we spotlight communities pushing the limits of what's possible on Discourse.
This month, we’re focusing on physical hardware. From solar arrays to 3D-printed manufacturing models, these are spaces where a single wrong answer means wasted parts, burned cash, or a fried circuit board.
Here, professional engineers troubleshoot alongside weekend tinkerers. It’s a dynamic that thrives on a shared, uncompromising goal: building something that actually works!
1. DigiKey TechForum
DigiKey, one of the world's largest electronic component distributors, runs a TechForum for the engineers and makers who buy from it. Categories mirror how engineers think: Semiconductor, Passives, Interconnect, Power, Embedded, Wireless and IoT, plus Maker, DIY, and a large Education section. Interconnect alone holds well over a thousand topics. Threads start with a datasheet or "what replaces this discontinued part" question and get answered with specifics: pinouts, tolerances, and footprints.

2. Victron Community
Victron Energy makes power hardware for off-grid, marine, and RV systems, and its community serves professional installers and DIY builders side by side. The categories keep them from talking past each other: Q&A and troubleshooting for installer-grade questions, a dedicated DIY space for beginners and small-boat owners, Modifications for Raspberry Pi, MQTT, and SignalK integrations, a Node-RED home, and Show us your system for finished-install photos. Threads walk through wiring diagrams, load calculations, and firmware behavior.

3. McNeel Forum
McNeel makes Rhino 3D and Grasshopper, used by architects, product designers, jewelers, and engineers to model geometry that gets built or manufactured. The forum is where they trade techniques and report bugs straight to the developers. Categories track the workflows: Rhino for Windows and Mac, Grasshopper with plugin subcategories like Kangaroo and Lunchbox, Rendering, Serengeti for work-in-progress builds, and Jobs and Portfolios. A typical thread is someone stuck on a shape who gets a working Grasshopper definition back, or a bug a developer picks up the same day.
We're looking for forums that have built something interesting, whether that's a thriving knowledge base, an active developer community, or a space where meaningful conversations happen at scale.
If you're running a Discourse community and you're ready for your close-up, reach out to us at marketing@discourse.org.
We'd love to hear what you're building!
