Bat-signal by LeHof

thingiverse

This DIY bat-signal was crafted for a friend, featuring a 12V white LED strip that projects an authentic bat-signal onto walls or roofs. To prevent multiple light sources from interfering with the shadow, block off two LEDs on the bank. If you can find a brighter, safe lighting option, please share it. Don't forget to upload a photo of your project after completion – a small thank you for the effort put into this design!
