About the collective

Building public tools for Delhi's makers

We draw inspiration from outfits like Absurd Industries — focused, and relentlessly hands-on. We believe cities like New Delhi can become hubs for open hardware and software if we lower the cost of experimentation, share designs freely, and build local supply chains.

Our goal is to assemble a community of designers, engineers, fabricators, and writers who ship real tools — from electronics and networking gear to machine tooling and bio instruments — and then document them publicly so others can replicate, remix, and improve.

Everything we make is built to be understood. That means publishing schematics, writing up failures as honestly as wins, and keeping the cost of entry as low as we can. If you can solder, or want to learn, you belong here.

Focus areas

  • Open electronics
  • Networking gear
  • Machine tooling
  • Bio instruments
  • Local supply chains

How we work

  • Ship real tools
  • Publish everything
  • Lab nights in Delhi
  • No gatekeeping
  • Repair over replace

Inspired by

Absurd Industries

Bengaluru-based open hardware collective. Focused, experimental, and community-first.

CERN OHL

The open hardware licences we build under. Permissive, copyleft, and strongly protective of design freedom.

Right to Repair movement

The belief that people who own things should be able to fix them. Our north star.
