When [101 Things] didn’t want to copy Morse code, he decided to build a Pi Pico system to read it for him. On the face of it, this doesn’t seem particularly hard, until you look at the practical considerations. With perfectly timed dots and dashes, it would be trivial. But in real life, you get […]
It is well known that pictographic languages that use Hanzi, like Mandarin, are difficult to work with for computer input and output devices. After all, each character is a tiny picture that represents an entire word, not just a sound. But did you ever wonder how China used telegraphy? We’ll admit, we had not thought […]
Have you ever seen a toy and said “That wants to be a deck”? [Attoparsec] did, when his eyes fell upon the Little Talking Scholar, a punch card driven toy from the 1980s. It’s now a punch card driven cyberdeck. The punch card interface on the toy is only six bits, but sixty-four application cards […]
Morse code can be daunting to learn when you’re new to the game, particularly if you need it to pass your desired radio license. However, these days, there are a great many tools to aid in the learning process. A good example is the Morse Master from [Arnov Sharma]. The Morse Master is a translator […]
Do you know Morse code already? Or are you maybe trying to learn so you can be an old school ham? Either way, you could have a lot of fun with [felix]’s great little entry into the 2024 Tiny Games Contest — Morse Quest. This minimalist text-based adventure game is played entirely in Morse code. […]
One problem with ham radio these days is that most hams live where you can’t put a big old antenna up due to city laws and homeowner covenants. If you’re just working local stations on VHF or UHF, that might not be a big problem. But for HF usage, using a low profile antenna is […]
You might have to provide your own wrist straps and eye clamps, but if you want to learn Morse code, [Seth] has a web site for you. You can get code practice using the Farnsworth method and each letter is flashed before you as it is sent, which we assume will burn it into your […]
[W8BH] attended a talk by another ham, [W8TEE] that showed a microcontroller sending and receiving Morse code. He decided to build his own, and documented his results in an 8 part tutorial. He’s using the Blue Pill board and the resulting device sends code with paddles, sends canned text, provides an LCD with a rotary […]
We think of Morse code in terms of dots and dashes, but really it’s a kind of binary code. Those symbols might as well be 0s and 1s or any other pair of characters. That attribute is exactly what led to a sting operation a music lyric site called Genius.com pulled on Google. At issue […]
Both grizzled hams and potential future amateur radio operators are well-served by the market these days. Powerful and capable UHF and VHF handheld transceivers can now be had for well under $100, something unimaginable as recently as 20 years ago. Of course, a major part of the amateur radio scene used to be Morse code. […]
