Flashlight playing the Imperial March

Flashlight Modding and DIY Parts
1

This was on my to-do list for more than a year, I'm glad I finally did it.

Some flashlights produce some whining noise with their PWM; some lights make that noise themselves, but even the silent ones make noise when their light shines on dark fabric (unless they use a PWM frequency too high to be heard), due to the photoacoustic effect. Ever thought that noise might be fun? It is :)

Here's my Roche F6 with some very custom firmware, using PWM frequencies of 120-300 Hz

Ok the flashlight is pretty cool but that’s just awesome, is that real? I’ve seen a tesla cool fired in person so I know what they sound like, did they actually orchestrate that or is it special effect?

Probably special effect for movie…but it is real
