Vail Adapter: Morse Code Key/Paddle to USB

Vail adapter, assembled and connected

Features

  • Lets you key even if you move focus to another window
  • Works with Vail
  • Works with VBand, but the window has to remain focused
  • Optional sidetone generator, which helps with latency
  • Implements all nine keyer modes from Vail, in the adapter, so you lunatics can try to key at 50WPM with no latency issues
  • Plays received signals in the adapter, so you can turn off your computer speaker
  • Free firmware updates for life
  • Can be wired up in about 5 minutes

Vail Adapter benefits video (4:46)

Setting Up

Future Work

Things I plan to add:

  • PCB to ease assembly and make a more robust shippable product
  • Debug tone changes
  • PCB v2 to get the speaker on pin 10 instead of pin 9
  • Unplug detection: send a pulse out one pin and detect it on the T pin to reset straight-key detection

Similar projects

  • Vail user Michele Giugliano's MorsePaddle2USB, which runs on a DigiSpark (attiny85). It only sends keystrokes, so you must keep the Vail window focused: you can't switch to other apps and still transimit.
  • Ham Radio Solutions sells a USB Paddle Interface which appears to be very similar to Michele's project. You must keep the Vail window focused.
  • CWKeyboard looks almost exactly the same as the VBand adapter.
