Hello List!

Today on our weekly Mumble session we talked about the "triple-5" once 
more. So I got itchy fingers and set up my personal repository for that 
on github (https://github.com/chipforge/CMOS-555).

Well, no repository without content - please check the README file and 
see the Schematic I already draw now. For everybody which is lazy to 
install Lepton-EDA (as describted in the README) I attached a fency 

Please check the Schematic, based on the Wikimedia SVG drawing, for 
mistakes I did. All dimensions for the transistors (Width, Length) and 
the restistors (Resistance) are still just generic. This task I suppose 
will do someone of you which is more an analog guy than me :-)

BTW, Tatzelbrumm and Ference, do you like to clone the repository and 
we're merging each other? Or, otherwise I can shift the repository to 
the github.com/libresilicon group and we are working there. What do you 

Best Regards,

P.S.: Other versions of the CMOS "555" circuit I saw, will follow soon 
as schematics - one e.g. even has on BJT.

safety, deserve neither liberty nor safety." Benjamin Franklin (1775)
