Place to find out about cool new integrated circuits online?

Even a hobby list would be really broad... Just look at the topics covered on this forum, which range from daylight following chicken coop doors to drones, from stepper motors to super low power wireless sensor nodes, from automatic greenhouses to model railways, and just about anything in between and around it. Many different chips get mentioned in the process.

Then consider that this forum covers only a specific subsection of electronics related hobbies!
