  • Can I build speakers that I don't have to wire?...almost!

    Lookout! The technology is on your doorstep.;) Before long, running speaker wire will be a thing of the past. Sort of 'set-n-play'.:rolleyes:

    If dynamite was dangerous, do you think they'd sell it to an idiot like me?

    They appear to be similar to THESE but smaller. BTW, it's pretty amazing those are good to 20Hz.:D

      Induction tech? Isn't it just a mic with an amp?

          Love the way they advertise "wireless"... yeaaaa, cool.

          But it has to be placed directly on top of this unit in order to work...... Dooohhhh!!!!

            Tesla saw this coming. You know it was his first priority after making the coil, wireless low quality audio.

              Well, you forgot Tesla's REAL love of "collecting electricity from the ether". That is looking like it's not as "wooooo-weeee" mad-scientistic as we imagined. Tesla wanted to use "ground wave" ultra-low frequency propagation for audio. We've done it with our submarines since 1936 it turns out (just over a year after his death). In fact, everything he predicted except the laser beam was perfected within 7 years of his death. Tesla actually invented the solid state amplifier (transistor) using selenium diodes before he died. The gain was so low they were only considered solid-state switches.
              Tesla's idea of electricity from the atmosphere wasn't nutty, his "coeherers" (coils) were just WAY too low. About 50-150 miles up in the ionosphere, where most of the solar wind and cosmic rays are dispersed by the Earth's magnetic field, there's LOTS of electrical energy to be collected. Some amateur rocket builders just recently fired a 50-odd foot rocket with a liquid helium cooled coil of a super conductor to about 85 miles high and used it to charge some "super capacitors" and the "super coil" (which Tesla said was the way to store electricity). One of the guys in my train club showed me this on his i-Phone at tonight's club meeting. He's a middle-skrool science teacher and a civilian rocket guy. In a very few seconds, they collected enough electricity to power an average house for 3-4 hours, something like 15 Kw/Hours.
              Back ON topic, just get a legal clear channel radio frequency, transmitter and receiver, build amplified speakers and you're in biddness. You still need AC power for you amps and receivers in the speakers, unless you want to shoot microwaves across the room and thru the dog, etc. to power 'em...

                I called Kit today about where it was posted, and it's on an Android "science news app", and he's in the middle of the State Minimum uniform "achievement" to see if they get OUT of middle skrul or not. He just didn't have the time to give a link. I Think it was like "science frontiers app". Amateur rocket guys bought(stole) tons of Iranian/Iraqi missiles up to about 20 meters for vastly improved versions of the old WAC Corporals. They stick older model Apple netbooks in them to operate the mission and for attitude control. Kit has some iPhone video of his buds launching a TWO-stage about 100 foot tall missile out in the Panhandle. If NASA would allow it, they could have put 5-10 kilos in a LOW retro-grade Earth orbit. Defiantly Sino/Russo design/engineering in all these, but with up-graded "smarts", they are mid-60's "medium-sized" US tech. (Minuteman III's were CRUDE compared to these) except for range and guidance.
                It's very strange, a Gov't contract is let for an aircraft,rocket, etc, and a sharp guy will design a Type Zero-Zen fighter, or a P-38 (J-LO-17 on), an ME-262, a Walther U-boot that can finally be a REAL submarine, spending about 80% of it's time under water with a top submerged speed of about 20 knots, (25-40% FASTER than most corvettes or destroyer escorts used to protect convoys) vs: 85%+ of the time on the surface for "regular" subs with a top speed on the surface of MAYBE 19 knots and a submerged speed of 7 knots with a two-hour battery life. (Any other ol' farts remember tube-type "portable" radios using either 4/8 D cells or the funky double length, same diameter "AD" heater batteries and the 22.5, 30, 36, 45, 72, and 90 volt "B" screen/plate batteries?) We had a little ( bigger than a cigar box!) aqua Zenith. My Dad's late Father just HAD to have one of the earliest pocket AM transistor radios, so we shlepped down to the Radio/TV store (high-priced!) and paid $79.95 plus 2% sales tax for him. It used the funky squarish shaped (from the top) nearly as long as a "C" cell. Hard to find!!!
