In this video I build a bat signal from a lensed flashlight beam. This design can be used to project any image, or simply act as a spotlight. For the light source I'm using the Imalent MS18 flashlight, which you can check out here (this is not a paid endorsement, but I was sent the flashlight for free to use in this project): https://www.imalentstore.com/products...
Similar fresnel lenses as the one I used in this video are available on eBay. I used a lens 250mm in diameter with a 500mm focal length. You can find some here (this is an affiliate link): https://ebay.to/2In1Nzt
