I built an interactive Music Theory course 8 years ago over a winter break and it continues to bring in enough to pay my rent each month. I just thought there had to be a more intuitive way to learn music theory than the very boring and jargon-heavy alternatives. It uses Tone.js to include little interactive pianos, guitars, and other demos. I've done no marketing, it hit the HN front page for a day, and after that i…

I really like the overall design of the site! I'll probably inspire from it for some of my future projects.

I built custom electric cars, and now I am sharing my knowledge for free in a knowledge base and in a YouTube series: https://foxev.io/batteries https://youtube.com/@foxev-content I hope this helps someone :) My knowledge is EV and renewable energy knowledge from first principles and for an open source tool. https://openinverter.org lets you re-purpose the drivetrain from any EV, like Toyota Prius or Tesla Model S an…

Nice work!

Not quite 500$/month, but my book https://www.handsonscala.com/ is still making 300-400/month 4.5 years after releasing it. Not a lot of money compared to silicon valley FAANG salaries, especially given the amount of effort that went in, but it's a nice feeling to see the dollars trickling after so long

Thanksgiving last year, after GPT-4 was released, I realized large language models were finally good enough to bring my idea to life: an AI book generator. Over the holiday weekend, I built the prototype for https://instabooks.ai , to allow anyone to instantly generate 200+ page books on any topic. I sell them in pdf, epub and print form and they take about 30 minutes to complete. Since launch, over 10,000 books have…

I am a little unsure of how it works, but it is very intriguing. Can I order a book on Writing Effective HN Comments from you? Who would be listed as its author? If I wanted to be the author, would I have to pay you? Is there an option not to have the book listed on your page? Do you have an FAQ? : - )

Earlier quoted context omitted.

My bad, TradeInsight without s. :( Maybe this is why I didn't get customers, keeping typing it wrongly. :(

The plural version is still available. Might be worth it to buy that one.

:) Yeah

https://FreeSolitaire.win brings around $500/mo in advertising revenue. It’s a Klondike Solitaire PWA (progressive web application). I started making it in 2016 and I’ve been slowly iterating on it over time. It has stayed minimal & lightweight, on purpose. No framework, no cruft, no obtrusive ads. Fun fact: because it’s so lightweight, it was included in 2020 in Moya ( https://play.google.com/store/apps/details?id=n…

Impressive! Its well made and such a simple idea making $$$ with some innovative thinking! How does reverse-billing work in case of data usage?

Thank you!

Regarding reverse billing: I don’t know much. I am not myself billed by Moya, although they do bill some of their partners. Please see https://datafree.tech (that’s quite specific to Moya / South Africa carriers, I guess)

I've worked on and run [link redacted] and the related subreddit and forum for 15+ years. I've generally done everything alone as an exercise in scaling utility for others with constrained time on my part. Have used AI heavily in the last few years, which has been the greatest force multiplier of my career for sure: scraping, evaluating, summarizing, organizing, indexing, moderating, writing, ... I've coded so much a…

I wonder if the new medicines are a factor on your project (from sponsorship to new treatments)

It’s not really MMR but I have a side business when I provide software for online and in-person festival payments (entry/food/drinks). If you take the total revenue (or profit) for the year and divide by 12 I’m well over the $500/mo limit. I currently do 3 festivals a year which all pretty much fell in my lap, I’ve yet to start any sort of sales/marketing due to being busy with my day job/life and not wanting to grow…

You've done a lot of work, and this seems like an excellent way to ensure events run smoothly! Great work in building a useful service for festivals & vendors and reduce the transaction fees to ... well ... as low as they can realistically go given the payment rails :)

Can I suggest you add a marketing video or some graphics to explain how easy it is for the festival company and the vendors?

I was laid off at the start of 2024 and built https://interviewsolver.com which is an AI copilot for helping you with your leetcode interviews. Doing about 6k/month, though the space is becoming fairly crowded.

Dude, that's cheating!
