Project Catalog
A catalog of large DIY builds — projects I've done and ones I know about — spanning 3D printing, CNC, robotics, and home automation.
3D Printers
Voron
Family of high-performance open-source CoreXY printers (2.4, Trident, 0, Switchwire) known for speed and build quality.
RepRap
The original self-replicating open-source 3D printer project that spawned the entire desktop 3D printing movement.
Prusa (MK4 / MK3S+)
Widely-cloned open-hardware i3-style printers, with the MMU3 add-on for multi-material printing.
RatRig V-Core
Open CoreXY kit printers (V-Core 3 / VZBot lineage) popular for large, fast, high-quality builds.
Annex Engineering
Community of open printer designs (K3, Tridex, BeltPrinter) pushing unusual kinematics and belt printers.
Positron
Compact, portable, upside-down printer with an integrated screen — a striking open-hardware design.
Multi-material & Filament
ERCF (Enraged Rabbit Carrot Feeder)
Open multi-material unit that feeds many filaments into a single Voron/Klipper toolhead.
Box Turtle
Open-source automatic multi-material system (AMS-style) for Klipper printers.
Tradrack
Rack-style multi-material filament changer, an alternative approach to the ERCF.
CNC & Subtractive
PrintNC
Rigid steel-and-3D-printed open-source CNC router capable of cutting aluminum.
MPCNC / LowRider (V1 Engineering)
Mostly Printed CNC and LowRider: accessible, low-cost open CNC/router platforms for wood and sheet goods.
Root CNC
Modular open-source CNC design using extrusion and printed parts, scalable to large work areas.
Maslow CNC
Large-format vertical CNC router aimed at cutting full sheets of plywood in a small footprint.
Science & Imaging
OpenFlexure
3D-printed, precise open-source microscope with motorized stages — used in research and education.
OpenScan
Open-source photogrammetry 3D scanner built from printed parts and a camera/turntable rig.
FarmBot
Open-source CNC farming robot that plants, waters, and weeds a raised garden bed.
Robotics & Outdoor
OpenMower
Open-source RTK-GPS robotic lawn mower, converting cheap commercial mowers into precise autonomous ones.
InMoov
Life-size 3D-printed open-source humanoid robot you can build piece by piece.
JPL Open Source Rover
NASA/JPL six-wheel rocker-bogie rover you can build as an educational hardware project.
ArduPilot / PX4
Open autopilot stacks powering DIY drones, planes, rovers, and boats.
Home Automation & Electronics
Home Assistant
Open-source home automation platform with local control and a massive integration ecosystem.
ESPHome
Configuration-driven firmware for ESP microcontrollers, tightly integrated with Home Assistant.
WLED
Fast, feature-rich firmware for controlling addressable LED strips over WiFi.
Frigate
Open-source NVR with real-time AI object detection, popular alongside Home Assistant.
