HushMe Bluetooth Device Reinvents The Hush-A-Phone
All things are made new in our amazing world of technology; up for renewal in this case is the hush-a-phone, which was originally sold in 1921, but was also used (and updated!) by science fiction Grandmaster Robert Heinlein in his classic 1940 story The Roads Must Roll:
...the incident would not have been worth recording, had he not been talking into a hush-a-phone which he had plugged into the telephone jack at the base of the rotor.
Gaines reached the group as the capture was being effected. He snatched at the soft rubber mask of the phone...
Now that you have some historical context, view with amazement the HushMe bluetooth privacy device for modern wireless telephony, I mean, smartphones.
