Hi Graham

Now with the standards Jim mentioned the return loop is just about
inevitable (in time) .

I've had a similar dream ; is the bulk feeding development far enough to
have a flip pin [with a slide slope incorporated] or air puffer (yes
blowing controlled dose of air ; let's keep it technical here folks ;
and I really do not want to mention the vibrating reversing loop
possibility here [takes too much room]) on colour sensor incorporated to
handle all polarized SMD's ;
or do we have to make it ourselves ?
This tapes rhyme with apes (Steve's bad influence) ; the waste ; space;
peel, handling , etc. ! ; drive me nuts ( do you know why squirrels run
after Harleys? ) . I can live with them on chips but on passives it's
extreme .
Not with squirrels ; >the tapes .

Who would know ( not "think" ) ?

PS
presently ; Graham , I'd worry only about power items .

Thanks a lot for raising the subject .
