About

I am an Amateur Scientist inspired by the old Sci-Am articles of the same name! I build home-made Lasers, Electronics projects, Computers and am interested in Chemistry & Physics, and publish these on YouTube. Support on YouTube has enabled me to share my work with like minded people, get one of my creations published in IEEE Sensors Letters, and even design and build a Supercontinnum Laser at home and on a budget, for what appears to be the first time!
