This is interesting. From the article:
"Wynter’s veil had concealed not only her face but a wireless radio."
Isn't that pretty advanced for 1919? A wireless radio that fed her information through an earpiece?
- paol 7y agoAll radio is wireless :) Radio was invented in the second half of the 19th century, so pretty mature by then. I guess a sufficiently miniaturized earpiece does sound impressive for the time, but it seems likely the radio itself would be too bulky and was likely hidden somewhere in her clothes.
- FreeFull 7y agoBy wireless it was probably meant that it was powered by battery, rather than by mains power.
- buckminster 7y agoI think it's using the old-fashioned terminology. A wireless or wireless radio is just a radio.
- em-bee 7y agoa simple radio receiver works without a battery. we built those in school. the electricity induced by the radio signal is enough to drive a small speaker.
- roywiggins 7y agoEspecially if you have a transmitter at full volume one room over, you'd be able to pick that up loud and clear on a crystal radio. I think you could make a small unpowered crystal radio using 1919 tech, since there's no amplification.
- Sharlin 7y agoSuch a device is commonly called a crystal radio[1] and they truly are ridiculously simple. If you don’t need a tuner or an amplifier, which in this case was likely, the only components required to build an AM receiver are an antenna, a diode, and an earphone. The name derives from an early type of diode based on a piece of crystalline mineral, discovered by Braun in 1874[2].

- nestorD 7y agoIt costed a lot but I have seen adverts for such hidden radio in magician's magazines from the time. There has always been a very lucrativ market for an engineer+magician that could provide hidden communication devices at the fringe of technology. One of the best and oldest device I found used a telegraph (!) hidden in a turban and shoes with copper sole on a copper threaded carpet.
- raverbashing 7y agoIt might very well be not a radio as we understand today, maybe a crystal one (passive ) with a powerful transmitter Easier in the times before the fcc let's put it this way
- brians 7y agoIt may not have been speech, but Morse code. AM voice was understood in 1919, but certainly not practiced at scale.
