[Sulaiman Habsi] and two classmates put together a Morse Code interpreter as a class project at Sultan Qaboos University. The system listens to a morse code signal using a microphone, then translates that input to text which is displayed on this character LCD. The breadboarded circuit feeds an audio signal from the microphone, through an OpAmp, [...]

[Bozar88] lives in an apartment building that has a buzzer at the front security door. Guests find your name on the panel next to that door, and press a button to ring the phone just inside the entry of each apartment unit. He decided to extend the built-in capabilities by adding a morse-code entry password [...]

Hackaday has seen dozens of Morse code keyboards over the years, but [Hudson] at NYC Resistor finally managed to give that idea the justice it deserves. He built a USB Morse code keyboard with the same type of telegraph key the pros use. For his project, [Hudson] got his hands on a wonderful iambic paddle that is [...]

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 [...]

[Mark VandeWettering] was experimenting with a simple transmitting circuit and an Arduino. The circuit in the project was designed by [Steve Weber] to broadcast temperature and telemetry data using Morse Code. But [Mark] wanted to step beyond that protocol and set out to write a sketch that broadcasts using the Hellschreiber protocol. This protocol transmits [...]

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 [...]

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 [...]
