For those unfamiliar with Ham Radio, there are lots of fancy tools these days to make it easier for the radio operator. But enthusiasts still like to get back to basics, and one way to do this is to participate in Straight Key Night. This is when you pull out your traditional Morse code keyer [...]

For [Davide Gironi] made a holiday tie tack this year. It’s not made to look like Santa Claus, Frosty, or a Christmas tree. He simply wishes you a Merry Christmas (‘Buon Natale’ in Italian) by flashing the message in Morse code. Two LEDs have been added to a plain tie tack. It is tethered to the [...]

To the casual observer this flower looks nice as its illuminated center fades in and out. But there’s hidden meaning to that light. Some of the blinks are longer than others; this flower is using Morse Code. [Renaud Schleck] wanted to try a few different things with his MSP430 microcontroller. He decided on an LED [...]

Ham skills prevail in this year’s LayerOne badge hacking contest. [Jason] was the winner with this Morse Code beacon hack.He got a head start on the competition after seeing our preview feature on the badge hardware development. It got him thinking and let him gather his tools ahead of arrival. The hardware is segregated into [...]

[Sebastian] is learning Morse code and CW radio, and of course he needed a telegraph key. Instead of using the terribly unergonomic paddle style key, he built a capacitive touch iambic key over the course of a few evenings. An iambic key usually has two switches. When one switch is closed, it will transmit a [...]

In the interests of interface archaeology, [Martin] sent in the Tworse Key, a telegraph key that posts to Twitter using Morse code. It’s a fantastic build that nearly looks like something out of the 1900s. We’ve seen a ton of Morse keyboards over the years, but never one so well-engineered for a single purpose. The guts [...]

The team a Zunkworks wanted to build a device for people who can’t normally use a keyboard and mouse. The Bluetooth Morse code keyboard is what they came up with. This build gives the user full control over the keyboard and mouse using a single button or a sip & puff interface. The project is [...]

[Eric] wanted to teach his kids Morse code, so he built a tiny Morse code trainer. [Eric] built the trainer around an ATtiny85, and the rest of the circuit follows this minimalist idea. After connecting a piezo beeper and 6-pin ISP header, the only thing left to do was write a little code and start [...]

Instructables user [tanbata] recently got his hands on a Google Anroid figurine and thought that while it looked great, it served no real purpose. He decided to change that, and converted this once-useless hunk of plastic into a miniature robot that moves and responds to sound. He pried of the head of the figure and [...]

[BadWolf] sent us a device called the “Bacon Beacon“, which is his 555 Design Contest entry. In short, it’s a life-saving device that emits an S.O.S. signal in Morse code over both the AM and FM bands. The device uses five 555 timers to get the job done, each of them dedicated to a specific [...]

LaunchPad dev boards from Texas Instruments are cheap and easy to program, making them a great Arduino alternative if you can do without some of the bells and whistles. [ech0s] put his to good use by constructing a Morse code transmitter with dual operating modes. The transmitter can not only encode and transmit messages entered [...]

Add a bit of interest to your radio equipment with one of these unorthodox CW keys. [OH6DC] has been hard at work posting almost sixty of these hacks. Above you can see an alarm clock whose snooze button acts as the key, and a nail clipper used as a key. There’s a banana , a [...]

[Johnny Carlo] put another spin on clock displays with his Propeller-based Morse Code clock. He repurposed a tap light, using the tap function as a switch input and actuating the bulb inside with the help of a transistor. If you want to know the time just give it a tap and the device will transmit back to [...]

Looking for motivation to practice morse code [BenB] built this morse code keyboard. It uses USB and is recognized as a standard keyboard thanks to the V-USB stack running on the ATmega168. The project is rounded out with a clean look thanks to the chewing gum container that serves as an enclosure. His design is [...]

[lucasfragomeni] built the Buzzle after being inspired by the reverse geocache puzzle. The Buzzle was built as a gift to a friend. It’s a tricky gift too. His friend can’t open it until he decodes the words being displayed in morse code via an LED. A word is chosen at random, so you would have [...]
