When the first radios and telegraph lines were put into service, essentially the only way to communicate was to use Morse code. The first transmitters had extremely inefficient designs by …read more Continue reading Translating and Broadcasting Spoken Morse Code
Lucid dreaming fascinates hackers. Every few years for over a decade now, we’ve seen a serious project dedicated to studying or taking advantage of this phenomenon, and the interest in …read more Continue reading DREEMWORK Lets You Code Morse From Inside Your Dream
Most of us use our hands to interface with computers, but the human body is capable of many types of input other than that of fingers and feet. But what …read more Continue reading Morse Keyboard Communicates with the Blink of an Eye
We always have mixed feelings about the drag-and-drop programming languages. But we were impressed with [SirDan’s] Morse code decoder built with the graphical MakeCode. Granted, it is reading 5 element …read more Continue reading BBC micro:bit Reads Morse Code with MakeCode
[Rostislav Persion] wrote a simple Morse Code decoder to run on his Arduino and display the text on an LCD shield. This is probably the simplest decoder possible, and thus …read more Continue reading Quick and Simple Morse Decoder
Code obfuscation has been around for a long time. The obfuscated C contest first ran way back in 1984, but there are examples of natural language obfuscation from way earlier in history. Namely Cockney rhyming slang, like saying “Lady from …read more
Since the ether is an old term for the fictitious space where radio waves propagate, we always thought it was strange that the term ethernet refers to wired communication. Sure, there are wireless devices, but that’s not really ethernet. [Jacek] had the same thought, but decided to do something about …read more
You really should learn to read Morse code. But if you can’t — or even if you can, and just want a break — you can always get a computer to do it. For example, [jmharvey1] has a decoder that runs on a cheap Bluepill dev board.
The device uses …read more
Google has been responsible for unleashing some pretty incredible hardware and software on the world, but they can only take partial credit for the voice to Morse code gadget that [WhiskeyTangoHotel] recently completed.
With the Google AIY Voice Bonnet, [WhiskeyTangoHotel] had everything he needed to pick up on human speech …read more
When we draw schematics, we have the luxury of pretending that wire is free. There are only a few cases where you have to account for the electrical characteristics of wire: when the wire is very long or the frequency on the wire is relatively high.
This became apparent after …read more
