I'm surprised nobody has mentioned findchips.com. I use it all the time to find which distributors have parts, and if a part numer (or partial part number) pops up, the link takes you to the distributor page that generally has the datasheet.
I used to search for parts on Google, but that's where I found all of my spam. I don't recall the sites, but I always seemed to get links that pretended to have the info, but just linked to other sites that linked to other sites... Then I gave up on Google.
Over the weekend, I've been experimenting with DigiKey, Datasheets and Mouser - running parts from my BOMs through. I did find an electrolytic to not be on Datasheets and a few parts to not be on Mouser. I tend to select parts based on what I can buy at DK, so I would expect to find all of the parts there.
Another site that I find quite useful is: http://public.wsu.edu/~brians/errors/errors.html It's about grammar, not technology, but, though I value function over form, form does help with good communications. This site covers all of those little things like "affect vs. effect:" that I ignored while back in school.
Mouser is where I always go first for parts and datasheets. For live pricing and availability when I don't find it in Mouser, I use Octopart, a specialised parts search engine that gives you real time pricing from several vendors on the same component. The hard work of finding obsolete parts info I leave it to Bing.
Thanks for publishing this list Kristin. I've used several of these sites, but there are others I had never heard of. Like you, I also have had good results with Google scholar to weed out everything that is *not* the journal article or academic publication I'm looking for.
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Are the design challenges the same as with embedded systems, but with a little developer- and IT-skills added in? What do engineers need to know? Rick Merritt talks with two experts about the tools and best options for designing IoT devices in 2016. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
