From my inbox: World’s smallest keyer and generating Morse Code with Javascript

On the CWOps mailing list, Martin, OK1RR, introduced his TinyKeyer, which he claims is the world’s smallest keyer. He writes:

This keyer, the (possibly) World’s Smallest Fully-Featured CW Keyer with Computer Support, based on Arduino design, employs the famous K3NG code. It can be used with any Windows/Linux/Mac logging or contesting software with Winkeyer USB (K1EL) support. The credit & big kudos goes to Anthony Good (Goody), K3NG, who did the tremendous work. It is a very small unit (outer dimensions 45 x 45 x 18.6 mm, appx. 1.8 x 1.8 x 0.73 in) which does not have any fancy options (a zillion of buttons, psychedelic flashing LED lights or cockatoo colored displays). It is intended for regular CW work and contesting with computer support, most of functions should be adjusted and operated via the computer. PCB or kits can be available depending on interest.

There’s even a Yahoo Group for support. To get on the list, send a messate to [email protected].

Generate Morse Code with Javascript

My old friend, Jack Vaughan, sent me a link to a blog page titled, “Generating Morse Code With JavaScript.”  Eric Holk, the author, notes that the whole program is less than 100 lines of code and uses the Web Audio API. This might be useful if any of you are thinking of developing an online CW tutor.
