If this why you read HN, I'd suggest checking out Hackaday, which gives you new content along these lines pretty much every day.
Would recommend checking out both the Hackaday blog and Hackaday.io. The blog covers news articles about hacks, and Hackaday.io is a place where a community of hackers share their own projects:
The main negatives I could say about Hackaday is the comment section on the blog is frequently a waste of time, and the UI of Hackaday.io could do with some improvements (IMO), but there's plenty of interesting projects to check out, and it's easy to ignore the comments section.
Hackaday is indeed great for finding out about neat projects. Don't read the comments, though. Everyone is hobbying wrong and they need to know it right now.
I too miss posts like this, but I'm glad we've at least passed beyond the "unicorn! unicorn!!", "here's how to bother your users incessantly" phase and seem to be on an upward trend in post quality.
@author (if here). Thanks, fantastic read and an even better gadget. You made me feel “O my, I need this!”.
