Do you know those odd little Chinese boxes sold as #CW trainers? I built an alternative: a #morsecode trainer for #flipperZero that teaches your ears first, rather than the usual visual teaching aids.
It generates LCWO-style exercises, grades straight-key timing, works as a VBand/Vail adapter and doubles as a #QRP rig.
No extra hardware required: the joystick works as a straight key or paddles. It can do elekey A/B/ultimatic and more.
