Hey everybody! Ive wanted to make one of these forever. Well, i have made one before but it was not a 'good' fresnel lens. If you want to learn more about fresnel lenses this is a good website - https://rimstar.org/equip/fresnel_lens.htm They have a youtube channel too with lots of educational content. https://www.youtube.com/user/RimstarOrg And of course shoutout to The King of Random where i first saw this idea ! https://www.youtube.com/watch?v=jrje73EyKag
