Dan's suggestions are similar to what I've received from one of our
suppliers:
Use a .050 diameter copper circle with .100 solder mask opening in 4
places. Making the part as a pin may include a drilled hole (which you
don't want). What I did was make a part with one surface mount pad of
Hi,
I am a geda newbie. I am trying to design a circuit and draw the
schematics using gschem. The circuit uses AT90S2313 micro for which
the symbol is available under micro. But I cannot see the pin 10,
Vdd and pin 20 Vcc on it. Is there any reason for not putting them in
there or is there

When I'm using 7414 as oszillator I usually use the third circuit.
This only works with IC's that have schmitt-trigger inputs.
What values (or ratios) of R3 and R2 do you use?
Depends on

You can just remove it if you don't need exact symmetry.
I'll try a board with it removed. I don't care about symmetry, just
something functional with the least number of parts.
R2 is usually 10 times larger than R3.
Ok, thanks.
Why in hell do you use such damn small parts ;-).
That's

The AT90S2313 has been obsoleted by Atmel and replaced with the ATiny2313.
