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): www.imalentstore.com/products/imalent-ms18-100000-…

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): ebay.to/2In1Nzt

Batman: "What is wrong with this guy? I've been there 8 times tonight for nothing. No Penguin, no Riddler, no Bane. You sir got some explaining to do."

Cool. Now replace the bat emblem with a a clear LCD screen and project animated shapes.

The insects that are attracted to the light might even attract real bats!

POV: You are a sleeping squirrel. Suddenly the entire world lights up like it's mid day.

"You can't even have your hand in it for long because of the heat" Proceeds to stick face in front of it xD
@JRaiKetchum134 3 years ago

That is amazing! I mean with 10,000 lumens, you can see the light beams clear enough to see them cross over at the focal point in front of the lens.

Epic. So much possibility for shadow art. Man that flashlight is so bright! Haha I'd love to try this with some Phantom cameras and see how far I could push the frame rate from one point source light.

I remember when parties in cities were pinned by "skytracers", these setups were huge !

I like how you can clearly see the upside down crossover when you shined it on the trees, impressive project there.

DIY Perks: *Invents artificial sunlight so that Superman can always be at full power. Ben: "Lemme just call the Batman real quick." Awesome video but needs more Mose 😁

That was super helpful. You explained perfectly why my bat signal was not working. Thank you.

please keep this around for when you do get some really low clouds someday. I have my doubts as to whether or not the image will work on the clouds but I really would like to see you try!

Brilliant. When that fan kicked in on the torch, I knew it was the business.
