Projection Calculator

Projection Calculator is an Android app (iOS coming soon) to calculate the right projector and lens for the job. As of tonight, Sept 22, the release is a working beta. The math is working for Barco projectors, and I'm working on adding Epson, Panasonic, and NEC as much as I can. The Epson lenses have been a particular coding challenge, because the throw ratio changes based on the lumen value of the projector it's put into, but progress is happening regularly. I don't work full time, and the holiday slow season will be here soon. -Adam van Alderwerelt, Sept 22, 2025
