Ask HN: Those making $1,000+/month on side projects - what did you make?

I run a forum (historic vehicles) members donate to see additional content, mainly old posts and bigger images, this is the primary income. Our recurring income is in that range.

Certainly not hi-tech but valuable to our membership and increases by at least 10% each year.

We don't run any keyword advertising but in the past year I we started selling advertising space in 12 month plans which has supplemented income.

Facebook has taken a bite out of our daily posting figures but it has made no difference to traffic/income. Facebook can't compete when it comes to delivering old content.

There are several associated niches to ours which don't have a centralised web site, much potential, you do however need a good knowledge of the subject matter and time to build the community.

http://www.brombone.com ↗

It's a service that solves SEO for javascript driven websites.

For the most part, Google can't crawl sites that manipulate the DOM using javascript (AngularJS, Backbone.js, Ember.js, etc). The solution is to use a headless browser to make html snapshots for all your pages and serve those to Google instead of the page that requires javascript.

This turns out to be a bit of a pain in practice. So, BromBone does it for you. It generates, hosts, and updates the html snapshots. When Googlebot visits your site, you proxy the snapshot from BromBone and serve it to Google. Now Google can see the same thing your users see.

I started a bag company, https://www.missionarybag.com/ ↗, for a niche market (young adults who leave home for 18 months to 2 years). A contract sewer here in the US makes the bags and my stay-at home wife does the shipping/handling. This is our first month to hit $1,000 profit in a month in under 6 months. After spending 12 years in software development, I wanted to create something tangible. And all the ecommerce/SEO/marketing I have helped others with over the years has come in handy - learning a lot in the process. We are looking to fill some larger orders with an overseas manufacturer.

My blog at http://erica.biz ↗ makes more than $1,000/mo in advertising and affiliate commissions.

I built the blog after I bootstrapped and sold my first tech company. I talk a lot about growing your business/startup, and especially about all the failures I had while building my businesses. It became popular (1.2 million unique visitors last year alone.)

I've now been blogging there for just over 6 years. Today I'm more focused on my startup, so my blog isn't bringing in as much income as it used to (though it's still over $1,000/mo.) My best month was over $24,000 in income.
