This first one I built was from parts in my junk box.
A scrap vector board and a db-25 connector.

Through it together one late night.
Looked like hell, but its such a simple circuit.

Never worked.

Second one, I built with a little more care.
Some new parts, some scrap parts.

It looked like it worked, and the slowest speed. But it was flakey.
Failed more then it worked. ( Atmel demo board)
So I bought one from sparkfun.com

That one worked fine. So I built another just to see if I lost 
my knack in building things.

The last one seemed to work OK, but still flakey. 
I just gave up and use the pre-built one.

I have been building things for 20 years. This is not new.
Whenever I see someone posting a message that they can not get
a wiggler working, I have to ask "did you build it yourself ?".
Most times its yes, "but its such a simple circuit !!"

go figure.
