Hey Vang, imagine turning a city billboard into a giant kaleidoscope that throws your slogans onto the clouds. I've got a prototype made from old plastic lenses and a solar charger—want to help tweak it?

Great! Grab a 50 mm focal length plastic lens, mount it on a tripod, and tilt it 15 degrees upward. Use a 12 V, 5 W solar panel to power the tiny LED strip that feeds the billboard image into the lens. Wire the LED to a microcontroller that syncs the billboard’s text to the light pattern. That’s the low‑budget spec—adjust the tilt a few degrees for each city skyline, and we’ll have the slogans swirling like a neon comet. Ready to roll?
