  • @83679

    go die in a hole, like you could make this

  • That's amazing! Are there any resources out there for someone wanting to try this for themselves?

  • Does the DC heat up the Xformer or do you have a dc blocking cap after the xformer?

  • @405mikey91 That was a laser shooting done from the space station to where it modulated off the rock(s) and caught the adjoining bush on fire so they just saw the bush but heard the modulation off the rock which was the transducer for the sound. The funny part is it probably sounded like James Doohan, (In his Mr. Scott voice)... What they heard at first; "Aye Captain, we can't get more outta her. Theres no one down there to hear ya anyway. Just keep talking so I can tune it in a bit better."

  • We want MORE! You were about to explain the power supply! 

  • @83679 you're a moron
