I second that love for Digikey. It's easier for me to buy from them 9.000 km away from them, than going to a local store here in my country. I usually have the parts in 4 or 5 days and everything is well packed. Also the search engine and order placement is great.
A question about pricing on FPGAs, and just out of my curiosity. Why is it the most expensive ones cost over 50k dolars? I know they have great paralelism capabilities and a lot of IOs but god those are expensive! 2016-01-31 21:10 GMT-03:00 Dave Cole <linuxcncro...@gmail.com>: > On 1/31/2016 6:51 PM, John Kasunich wrote: > > > > On Sun, Jan 31, 2016, at 06:18 PM, Gene Heskett wrote: > >> On Sunday 31 January 2016 13:43:50 Jon Elson wrote: > >> > >>> I can't imagine why you'd buy commodity semis from a Chinese > >>> source when there are great distributors like Digi-Key and > >>> Mouser, that are quite happy to serve small orders. > >>> > >> Both of the above have minimum orders for me that are quite costly for a > >> 10 pak of anything in the transistor 10 cent to 5 dollar price range. > >> That and their sites search engines return what looks to me to be random > >> from dice throws results.
