PiPiece

A Raspberry Pi 5 case for use with the HQ Camera V3 and a HyperPixel 4.0 screen.

PiPiece UI

A Raspberry Pi-based camera control system designed for astrophotography, featuring a web-based interface for controlling the Raspberry Pi HQ Camera.

M27

The Dumbbell Nebula (also known as the Apple Core Nebula, Messier 27, and NGC 6853) is a planetary nebula (nebulosity surrounding a white dwarf) in the constellation Vulpecula, at a distance of about 1360 light-years.

NGC 7293

The Helix Nebula (also known as NGC 7293 or Caldwell 63) is a planetary nebula (PN) located in the constellation Aquarius.

M1

The Crab Nebula (catalogue designations M1, NGC 1952, Taurus A) is a supernova remnant and pulsar wind nebula in the constellation of Taurus.

M8 and M20

Messier 8 (the Lagoon Nebula, NGC 6523) and Messier 20 (the Trifid Nebula, NGC 6514) are bright nebulae in Sagittarius.

M33

Messier 33 (NGC 598) is commonly known as the Triangulum Galaxy.

IC443

IC 443 (also known as the Jellyfish Nebula and Sharpless 248 (Sh2-248)) is a galactic supernova remnant (SNR) in the constellation Gemini.

Projects

My personal projects fall into a few areas. I like designing and printing 3D parts, and I use OpenJSCAD for many of them. I also enjoy astrophotography and have a few software projects focused on it.

3D Printing

Bahtinov Mask - A parametric Bahtinov mask generator for astrophotography. Create custom-sized 3D-printable focusing masks tailored to your telescope's aperture and tube diameter. Built with OpenJSCAD, this tool generates precision masks with adjustable bar width, gap spacing, and resolution for optimal focusing performance. GitLab Project
PiPiece - A Raspberry Pi 5 case for use with the HQ Camera V3 and a HyperPixel 4.0 screen. GitLab Project
picam3 - A Raspberry Pi case for the HQ Camera. GitLab Project

Astrophotography

PiPiece UI - A Raspberry Pi-based camera control system for astrophotography, with a web interface for the Raspberry Pi HQ Camera. GitLab Project
fits-viewer - A streaming FITS file loader that allows processing while data is still loading. The example application creates an image from 1-axis or 3-axis FITS images as data chunks are read. GitLab Project
phd2 for pitablet - A customized version of OpenPHD2 for an 800x480 screen.
scope-pi - A Raspberry Pi case that fits on a telescope. GitLab Project
scope shelf - Using a Raspberry Pi with the 7-inch LCD on a telescope works well, but it needs a place to rest near the scope because of attached cables. A telescope hand controller has a clip for hanging on a tripod leg, and this provides a similar solution for the small tablet.

OpenJSCAD

jscad-browserify-test - A test OpenJSCAD project that uses jscad-utils and the CSG viewer. GitLab Project
jscad-utils - A collection of utilities for OpenJSCAD projects. These extend CSG objects with utilities for alignment, scaling, and colors. It also includes basic parts that use outside dimensions rather than radii. GitLab Project
jscad-raspberrypi - A collection of OpenJSCAD parts that model the Raspberry Pi B+ and various HATs. These models use jscad-utils and return jscad-utils group objects. GitLab Project
jscad-hardware - A collection of OpenJSCAD parts that model common imperial and metric bolts and washers. These models use jscad-utils and return jscad-utils group objects. GitLab Project
jscad-gears - jscad parts library to create gears
jscad-test-utils - Utilities to help test jscad project using image snapshots and AVA
