Re: A few extra component footprins

I'm attaching the Sharp SSR library complete with symbol, footprints

think the symbol is a good candidate for the opto lib. Please let me
know if there's anything I need to correct.

Footprint and 3D are very good. Small addition to both would be reverse horizontal orientation (heatsink pad upwards from the seating plane). Wire bending radius may need some checking. The radius seems to be a bit low. In isolated packages the mounting hole shoud be left without pin number as it's not connected to any net. Oydvinds transistor example boards shoud be of help. Pin numbering is a bit weird too as it seems "the missing pins" are counted too. Could you offer some explanation?

We should also agree on coherent (and possibly pleasant) symbol drawing style to get a consistent look for the whole schematic. http://users.tkk.fi/~vsolonen/kicad/ has some example libraries and symbol guideline document for starters. Please comment on the gudelines if they seem unreasonable or flawed. Guideline sizes at least need some work.

I still haven't gotten a reply from Oydvind, so there's not much yet I
can do about the other components, if they are to be integrated into his

He may be busy elsewhere, but I'd guess he'll answer asap. He possibly knows the solution to the colouring problem also. Your hand drawn footprints and 3D was so good that I'll add them to the library any day. Scripting suggestion was just to spare your efforts to some really exotic components :)
