RE: gEDA-user: LED 100 != 5mm LED ?

["Bert Timmerman" <bert.timmerman@xxxxxxxxx>]

Hi kiu,

Sofar, you're probably doing nothing wrong here.

At least you found geda and made the step into the world of free software.

AFAIK, the 5 mm relates to the outer diameter of the body of the LED.

5mm LEDs have a pin spacing of approx. 2.54 mm --> 100 mil, this is correct
for the 5mm LEDs (green.fp, red.fp, blue.fp in optical).

Or are you refering to the diameter of the body on the silkscreen, this is
approx. 150 mil and this is indeed a bit small value for a 5 mm LED.

BTW there happens to be a pcb-20070208p1 release of pcb which doesn't use m4
anymore, only newlib footprints.

The directories have not been merged, that is, m4 derived footprints in the
newlib format live in lib/pcblib-newlib and the newlib contains the
footprints according to the newlib format.

Confused, you won't be after the next episode of this soap ...   ;-)   (no
pun intended)

Kind regards,

Bert Timmerman.

Onderwerp: gEDA-user: LED 100 != 5mm LED ?

Hi,

in geda/share/pcb/m4/optical.m4 a 5mm LED footprint is defined as "LED 100".
But if i print it my LEDs are to small.

Shouldnt it be 5mm/0.0254mm = 197 mil instead ?

I am a (g)eda newbie - am i doing something wrong ?

Thanks in advance...
