Preliminary Color Cycle Set Ranking Results
Since I launched my color cycle survey in December, it has collected ~9.7k responses across ~800 user sessions. Although the responses are not as numerous as I’d like, there’s currently enough data for preliminary analysis. The data are split between … Continue reading

Color Cycle Survey
A previous post about randomly generating color sets with a minimum perceptual distance addresses the technical aspects of generating sets of colors that are visually distinct for those with normal color vision as well as for those with color vision … Continue reading

3D-Printed Hilbert Curve Absorbers
Fused filament fabrication (FFF) 3D printers are good for many things,1 but production of sharp points is not among those strengths. Thus, the traditional structure of millimeter wave absorbers—a periodic array of square pyramids—is poorly suited for production via FFF … Continue reading

Photogrammetry Targets
The Scanreference photogrammetry system includes 149 magnetic coded targets and PDFs for printing 192 more targets. However, while measuring something that isn’t ferromagnetic, the magnetic targets aren’t particularly helpful, and the 192 printable coded targets aren’t always enough. Unfortunately, AICON … Continue reading
Volume of West Hill Pond
Since I have a bathymetric map of West Hill Pond, I thought it might be interesting to calculate the volume of the pond. The formula for calculating the volume of the frustum of a pyramid is where is the height … Continue reading
