Finally, I can realize my dream of making a floor out of radio tubes!
RADIO TUBE OF METAL CAN BE WALKED ON
Proof against the roughest handling, an indestructible type of radio tube developed in England is so sturdy that it may even be stepped on without damage, as shown above. A metal bulb replaces the customary one of glass, maintaining the vacuum and also serving as the anode; glass is used in the tube only to insulate the bulb horn the metal base, The tube is encircled by a metal cylinder for electrical shielding. It is designed for use anywhere but should prove especially valuable in portable sets or others frequently moved.
Using offshore systems to subvert a communication network to deliver ads for gambling, controlled substances and quack cures. Sure sounds like spam to me.
OUTLAWS MAY USE SUPER-STATIONS at Sea
Broadcasting stations without a country seek new ways to flood the United States with radio advertising barred by federal commission. Two hundred outlaws face war by the government.
by MURPHY McHENRY
RADIO circles on the Pacific Coast were turned topsy turvy not long ago by the; continued presence of a radio pirate ship which had taken unto itself a very popular spot on the dial and started broadcasting without regard for the land stations with which it interfered.
The primary purpose of the unlicensed broadcast station was to advertise the gambling, liquor, and other dubious pleasure activities of the ship upon which it was built—all these activities beyond the 12-mile limit, of course. Thousands responded to the advertising and the owners waxed rich. They found other sundry rackets, such as a fortune telling program, which brought in additional money and finally assumed such an extensive program that one Los Angeles station was threatened with; a complete loss of audience and business because the ship’s radio signal was the more powerful of the two.

If you build one of these, you too could be this cool.
Salt Water Powers Radio
Battery made of scrap metal and a pill vial runs for months!
By ROBERT E. KELLAND
THE salt-water cell powering this transistor radio has all the advantages of a dry cell, costs only pennies to make, and lasts for months. The complete radio receiver, with battery but less earphones, can be built for $3 or less.
As shown in the photos, the battery delivers about three-tenths of a volt. The radio consumes only 12 microamps while running, and in actual tests ran three days continuously without any detectable dip in volume. Read the rest of this entry »
I wonder which idea readers in 1924 thought was more plausible; mind reading automatons or cell phones. Whatever the answer, one thing is clear: we need to come up with some way to use the word “radioplasm”. Google only returns two hits on this word and one of them is in another language.
Reading Thoughts by Radio
Can thoughts be read by radio? “Madam Radora” seems to prove that they can. Madam is not a human being, but a life-size automaton shown at the Permanent Radio Fair in New York. Her “thoughts” and movements are controlled entirely by wireless; no wires of any kind are attached to the table whereon she rests, and a liberal reward is promised the person who can prove that this is not true.

The dog fired a revolver? That’s one dexterous dog!
Trick Dog Gets Orders by Radio
BY TEACHING a dog to do tricks under “radio control,” Constable Denholm, of the Sydney, Australia, police force, has fulfilled a two-year-old ambition. In a recent demonstration, he strapped a miniature shortwave radio receiving set on the back of Zoe, an Alsatian police dog, and retired to a shack fifty yards away. Then he spoke commands into the microphone of a portable transmitter. In response to her master’s voice as it came through the ether, Zoe climbed up and down ladders, turned a faucet on and off, took off her collar, and fired a revolver.
