A creative DIY project demonstrates how to transform old LCD TVs and projectors into high-quality displays by using the projector as a dynamic backlight. The modification achieves OLED-like black levels and contrast by removing the projector's color wheel and applying specialized image processing, resulting in performance that rivals modern displays at a fraction of the cost.
A detailed exploration of building a low-cost synthetic aperture radar (SAR) system mounted on a drone, capable of capturing high-quality polarimetric images up to 1.5km range, weighing under 1kg, and costing around 800 EUR in components.
An exploration of image dithering techniques demonstrates how to convert color images to black-and-white using various algorithms, including a novel approach that balances between Atkinson and Floyd-Steinberg methods. The author developed this technique while building Guten, a custom newspaper printer that requires monochrome images, showcasing practical applications of dithering in modern technology.
