Albert Einstein won his Nobel Prize in Physics in 1921 "for his services to Theoretical Physics, and especially for his discovery of the law of the photoelectric effect" [ nobelprize.org ]. The photoelectric effect, in part, describes the energetic response from photons and electrons reg
This blog is intended for young innovators interested in real-world applications to engineering. A maker-based approach is explored through written articles using Raspberry Pi and Arduino as central and control components. Topics range from heat transfer, acoustics, robotics, data analysis, sensor design, and more. Difficulty levels range depending on the topic and there is extensive focus on open-source software implementation, however, there will be articles with a focus on software design as well. The intention is to demonstrate applications of engineering that are repeatable at the intermediate level without requiring colossal resources.
