Vail Adapter: Morse Code Key/Paddle to USB

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

Setting Up

• Easy Setup
• Advanced Setup

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.
