Ask HN: Where do you publish projects?

I've written up a few projects for the Twilio blog (https://www.twilio.com/blog/author/acohen) but the majority of my projects aren't Twilio related, is there something like that (not just a personal blog) for random fun side projects? I usually make a combination of hardware and software (programmable robot for toddlers, automatic reader bee for baby, etc.)
