Ham radio HT CW transceiver project from WhiskeyTangoHotel.com: Really not much explanation needed; just connect as shown above. This project uses an electronic keyer, but a simple straight key/oscillator combo could also be used. Oh… and you will also need to know Morse Code.

The K7TMG HF Morse code temperature beacon
AA7EE published a new build, a little temperature beacon: This was a fun little project – and it gave me an idea for a future one. Sometimes, I find that the more complex undertakings, which require more planning, can get to the point that they “take me over” somewhat. At that point, for me, some […]
Modified Heathkit HD-1410 electronic keyer
Dilshan Jayakody writes: HD-1410 is quiet popular iambic keyer which is manufactured around 1970’s by Heathkit. The original HD-1410 keyer is designed using 5 commonly available 74LS series TTL ICs and 8 transistors. Other than iambic operation it has an option to adjust sidetone frequency and support for (external) single-paddle key unit. In this project […]
Bringing a vintage telegraph into the digital age
Kyle Gabriel writes: I recently inherited a key on board (KOB) telegraph that my late grandfather used to practice Morse code with when he was a kid (Figure 1). A little bit of curiosity of how it would work and a little bit of displeasure from seeing it sit and collect dust, I began a […]
Audible Morse code to text message converter
Dilshan Jayakody writes: Morse View is an open source software project to convert audible Morse codes to text messages. This application is capable to convert Morse codes from wave files or from the audio line/microphone inputs. Conversion from Morse code to text can perform based on amplitude and frequency decomposition of the input audio stream. […]
MSP430 based wireless temperature sensor
Toxic239 shared his wireless temperature sensor project based on the MSP430 microcontroller. It uses a 14.089 MHz carrier frequency which is modulated using Morse code, outputting “CALLSIGN T<TEMP> 73”. The source files are available in the forum. For an upcoming low altitude party balloon flight :D we had to put together a simple Morse transmitter. […]
Arduino Morse Code generator
Denver writes that he has created a Morse Code generator, and posted a tutorial in my blog about how it is done. His tutorial begins with an explanation of how Morse Code is organized and proceeds to explain the process of writing an Arduino sketch to produce the sequences of “dits” and “dahs” corresponding to […]
Bluetooth Morse keyboard assists the disabled
In an effort to assist computer users with disabilities limiting their keyboard dexterity, the crew at Zunkworks developed this wireless Morse code based keyboard interface device. The user keys in the desired characters using the “dot” and “dash” buttons on the left of the board and the Arduino based device converts these Morse code characters […]
TI launchpad as morse keyer
echOs built a CW(Morse code) transmitter using a TI launchpad with a minimal amount of components. Only capable of low power transmitting, this would be use full for finding that lost high altitude payload, or fox hunting. Via: Hack a Day
