The screen casting business means continuing to make a few new tutorials per month and making occasional improvements to its site. It sure pays a lot more per hour of my time than it did 18 months ago, though!
The starter kit is still in alpha, so there's a considerable amount of work to do. I'll be raising the price as it hits various milestones, though. Once it's "done", it will be mostly passive other than updating libraries.
Elixir is a rough market since it's very niche but still has a surprising number of authors, conferences and screen casters in its ecosystem who are also creating educational materials.
My MRR is fairly low, but it's just enough to cover my expenses living in Taiwan.
When I have the bandwidth, I'll launch another product which will be still more passive and it won't be limited to only Elixir devs. After that, the plan is to spend some money on outsourcing the editing of my videos and some routine social media tasks.
I guess you are not selling it just yet anyway. Anyhow, since I have multiple projects, going through the setup is hassle and I created started project essentially.
About two dozen people have bought it so far and will get the updates as I build it out. I also gave access for free (at least up through the beta version) to all the people who bought annual Alchemist Camp memberships at the end of last year.
That said, if you've watched all my tutorials there will be nothing new in it except the front-end components that still aren't done.
I don't put it front and center since my first goal is to get people to check out the free content, which is most of it. Eventually learners will usually try clicking on a premium episode, which is where the paywall shows up. The reason I do it this way is so that people will know exactly what they're getting when they sign up.
Also, even getting people learning from the 100+ free screencasts is a plus for me.
The other product is in alpha and the pricing is going up as I hit various milestones. It will probably max out around $250.
