Touch Switch: Revisited

I am wanting to make a touch switch for a set of paddles for morse code, for ham radio. I want it to be capacitive, not needing to make contact between two wires, simply one wire detects your skin's touch.

Ive been doing a good bit of reading, but I am asking for a revisit to this, has anyone gotten a good touch switch based on capacitance rather than resistance to work well with the AXE?

This is currently being discussed in detail in another thread.
Search: "Variable Capacitance Buttons!"

Before you give up try this:
Have you got a PICAXE LCD if not use the debug command instead.
Have one loose wire coming from a PICAXE analogue pin. Use
Code: 
readadc10 w0
for accuracy then either display the w0 on an LCD or debug it.
You'll be surprised at the readings.;)

M14 using leg 1

main:
readadc10 1,w1
debug w1
pause 200
goto main


Interesting, but... not sensitive enough.

Further discussion is invited.

Seriously try the other post there's lots of useful info on there. I'm about to post some killer info on what I just suggested - there must have been something wrong with how you were doing it.

I have my Picaxe proto board built and ready to use with a 14M on it (also have one for an 08M), but I am trying to get my serial LCD working before I more further with this experiment.

I have not abandoned this project, just wanted to build the proto boards before I dove further into it.
