(OT, probably) semiconductor components vendors
I decided to actually build something for a computer-related project;
first time for some years. I went to my usual supply-everything place, maplin, only to find their range of semiconductors seems to have diminished hugely since I last looked - they seem to be going the way of Tandy. But OTOH neither do CPC nor RS seem to keep what used to be commonplace ICs (I'm looking specifically for a waveform generator, 566 or 8038 sort of thing), and both seem to have huge swathes of items marked discontinued. So has the world gone completely digital? And where's the place of preference these days for buying odd bits for home projects? This is /so/ frustrating :-( -- Please use the corrected version of the address below for replies.

Farnell have the 8038, Mike. SKU 1209617. CPC and Farnell regularly differ in their stock. Another option is Dial Electronics, who stock most everything including obscure and obsolete stuff *if* you can get the swine to reply to e-mails. Minor detail with Farnell: Minimum order £20. -- Chronos |

Blimey, I took an interest in this as my O'level electronics project in 1983 centered around an 8038. Seems to be a very obsolete part thesedays - I think I still have most of the function generator I made with it somewhere, but I recall nicking some of the knobs and switches for something else! |

A lot of European distributors will be discontinuing RoHS non-compliant parts, and for older parts manufacturers aren't making them compliant. Digi-Key might be a good bet for non-compliant parts (just don't sell your projects on!) Cheers mark-r -- "Let's meet the panel.

Hadn't realised what RoHS would mean in practice: I suppose I vaguely thought it just meant lead-free solder and no cadmium plating :-) Looks like yet more homework...... -- Please use the corrected version of the address below for replies.

It is getting increasingly difficult to make anything unless you're planning on making thousands of them. It's a sham(e) as there are still many electronics hackers about. I heard it suggested a while back that an electronics club would be a good idea, but since most folks are building different things at different times I can't see it making much difference to the suppliers that require you to order thousands of something before they'll even answer the 'phone. Of course, a club/mailing list/group may create a big virtual shared junk box. I've got some pretty esoteric parts in the workshop and I'm sure others have the same. Hmmm, a virtual junk box. Backend (My|Postgre)SQL with people's wants and haves with a Ruby on Rails front end all wrapped up in some unreadable colour scheme to make it look 1337... Nah, it would never fly ;-) -- Chronos |
