▸ OpenDACT: Automatic Delta Kinematics Calibration Software

Github	Contributors on GitHub	2014 - 2017
OpenDACT (Open-source Delta Automatic Calibration Tool) is a calibration tool for delta robots. It calibrates generic delta robots and automates calibration of Repetier-firmware-controlled delta robots (primarily 3D printers). The calibration uses forward and inverse kinematics measurements to make adjustments. It takes Z-height readings at key XY points on a flat plate (print bed) to iteratively calculate hardware offsets. Users can manually adjust hardware or apply software offsets to correct for imperfections. This software solves for the following mechanical offsets: Diagonal rod lengths End effector radius Horizontal radius Endstop offsets Angles of the ABC towers For Repetier based robots, these offsets are automatically saved on the controllers EEPROM upon a successful calibration. Z-bed distortion on a newly completed build could have offsets of +/- 2mm across the plate, this tool (assuming issues in the above offsets) can calibrate the systems down to 5-10 microns. This software has been tested and successfully used on small-form factor deltas (100mm plate diameter) and large-form factor deltas (1.5 meter plate diameter).

▸ Proxmox VE Load Balancer

GitHub	Solo Project	2025 - Now
ProxmoxLoadBalancer is a Python tool that balances memory across Proxmox VE cluster nodes. It has two modes of operation: Simulation Mode: Test and visualize load-balancing algorithms in a controlled environment without touching the live cluster. Live Mode: Uses the Proxmox API to monitor memory usage and migrate VMs to balance load. This software is built as a stand-in until ProxmoxVE ships with a built-in cluster load balancer.

▸ Teensy WebHID Firmware Loader

This enables users to run high-performance workstations in various configurations while keeping things easy to manage, since each VM can be tuned for its specific OS or software.

Product Prototyping and Engineering

▸ Stewart Platform - Firmware and Hardware for Flight Simulator

Github	Hardware/Software Solo | Research by Co-workers	2020 - Now
The Stewart Platform project is an adaptation of a commercial system. The machine originally shipped with MDBox motion controllers, controlled via ethernet. Because of high latency it was adapted with a custom controller, upgraded 1000W AC servos for the linear actuators, and custom firmware and software. This was the start of the AetherControl project detailed above. The attached repository contains the interface code that takes target XYZ Cartesian coordinates and Euler rotations, then computes the six actuator lengths for AetherControl. The goal of the project was to adapt the system to handle high-frequency vibration and high-speed motion for research on flight dynamics. The inverse kinematics repository allows for custom user-defined configuration parameters, taking in: Base Plate Radius Base Plate Mounting Angle Platform Plate Radius Platform Mounting Angle Base Height Maximum Actuator Length Users can input an XYZ cartesian coordinate and Yaw-Pitch-Roll to get a returned value of each of the 6 actuator lengths.

▸ Custom 4-Axis Machines and Fusion 360 Post Processors

Github	Solo Project	2023 - 2024
This project primarily is a custom-built Fusion 360 post-processor for multi-axis laser cutting and engraving. It was created to cut complex shapes into vacuum-formed plastic visors. The software is a Fusion 360 post-processor that uses the machine’s hardware configuration to convert 4-axis toolpaths into G-code for a custom 4-axis laser cutter. The machine is an XYZ motion system with an additional large rotary axis that has an integrated fume exhaust system.

▸ 4-Axis Automated Gimbal for MEMS-Based Motion Processor Testing

Github	Solo Project	2018 - 2020
The 4-axis gimbal is the primary tool in a larger project. This project required accurate calibration of low-cost MPU6050 motion sensors. To perform the calibration a custom 4-axis motion system (3 rotational axes and 1 linear axis) closely follows a path while capturing the data (acceleration/angular velocity and for some also the magnetic field) from multiple inertial measurement units. A separate tool-the linked GitHub repository-simulates the system and generates ideal theoretical sensor outputs. Comparing real and simulated data is used to calibrate the system and develop filters for the sensors adjusted outputs.

▸ Wearable 3D Printed Designs with Integrated Electronics

Github	Solo Project	2020 - Now
Designed and built 3D-printable cosplay hardware-currently have six designs in total. For the Beta, Delta, Epsilon, and Sigma, each model is available on GitHub as STL files optimized for common 3D printers. Every project includes an electronics wiring guide, custom ProtoTracer firmware binaries, and source code. The Alpha and Gamma prototypes use real-time stereoscopic passthrough vision with a custom lens stack and display module. The vision-systems use modified software (running on a Raspberry Pi CM4) to reduce latency to about 15 ms and support the stereoscopic live synchronized display. This leaves as much area as possible for the LED displays. Each uses two synchronized microcontrollers to render live 3D graphics on the full-face displays. Integrated front-facing distance sensors and a 9-axis IMU modify the animation pipeline, so animations react instantly to motion and proximity.
