[CW] Good Sounding Sidetone or Code Practice Oscillator Kit

[N7DC]

I prefer something like the signals we used to hear.   Brash, chirpy, 
fading.   hehe.  I have the Boy Scouts build a simple key, and 
oscillator (if you can call it that) from a old computer part (the thing 
that covers the hole in the back of the case- covering slots for added 
cards).  Bend it, put a screw in one end to hold it, and another screw 
under the other end for a contact.  Wire it to a battery, and a buzzer 
from the shack, and viola, a signal just like we used to hear.  Give 
them perfect oscillator sounds, and when it comes to copying off the 
air, its much more simple.  Meantime, if they hear a lousy signal, they 
can copy it.  It would be hard to describe some of the chirpy, caustic 
signals I copied, back in my army days, and early ham radio.  Remember 
all those signals coming out of home brew in Russia?

I used the 555 as a timer for a circuit to time my enlarger in the dark 
room.  Worked quite well for that.
