Open-source project guides for domestic manufacturing. CNC, 3D printing, PCB fabrication, and automation — from your workbench to a working product. No offshore minimum orders. No 6-week lead times.
Step-by-step guides with full BOMs, wiring diagrams, and firmware. Every project is designed to be built with tools you already have (or can get for under $200).
Replace a $1,800 Hypertherm controller with an ESP32, THC module, and open-source firmware. Full wiring diagram and enclosure files included.
Molding / CastingUse silicone molds and vacuum degassing to produce short-run injection-quality parts. Cheaper than MOQ at any contract manufacturer.
Motion / ActuatorsDesign and build a closed-loop linear actuator using aluminum extrusion, a NEMA23 stepper, and a $12 GRBL board. Cuts the cost of commercial actuators by 80%.
Every week we publish a new build guide showing how to make real, functional products with desktop CNC, 3D printers, basic electronics, and open-source firmware. No alibaba minimums. No 6-week boat from Shenzhen. Just your hands, your tools, and good documentation.
Every project includes a complete Bill of Materials with exact part numbers and links to buy domestically.
STLs, DXFs, Gerbers, and firmware source. Download, modify, improve. No paywalls.
Each guide shows how to go from one-off to small batch. When you're ready to automate, io.codes is there.
Join makers and garage manufacturers getting one practical build guide per week. No spam, no fluff — just projects you can finish on a weekend.
You're in. First build drops Monday.
