How about a capacitive touch iambic paddle with built in keyer ?
Sounds like a perfect QRP project, using CMOS chips for Extra low current
consumption. for portable use, capacitive paddles means no moving parts to adj
ust or break. just strap it on the radio and go.
You could buy the CMOS-2 keyer kit for 45 bucks (complete info in the ARRL
handbook) and make the paddles out of aluminum. just need the touch circuit.
The Heathkit Micro-matic memory keyer used capacitive paddles. so the
circuits in there.
Quick, somebody put on the theme music to "Mission Impossible"
