I'm Marcus. I make Swift apps for iPhone and Mac, small servers that run in my homelab, and build logs for when the coffee machine needs a Zigbee relay. I use everything here myself.
yet another meal planner. fortunately, this one is good.
A self-hosted recipe library, meal planner and shopping list. There's no AI inside; it has an API and an MCP server instead, so the assistant you already use can drive it. Paste a recipe link, ask for five dinners, get a list sorted by aisle. The iPhone app works offline, even in a supermarket with no signal.
Spotify puts every podcast you follow into one feed. This splits them into playlists you define, like news for the commute or the next episode of a serial, and rebuilds them on Spotify every morning. Self-hosted, with an iOS app. Free for non-commercial use.
a smart Sage Barista Express, in two build logs.
How my coffee machine joined the smart home. Part one: two Zigbee relays soldered across the power and grinder switches, so it warms up when I get in the shower and grinds when I walk into the kitchen. Part two: a load cell in a 3D-printed dosing ring, so it grinds by weight instead of time. Photos, wiring diagrams and every mistake along the way.
An iPhone and Mac app for Vikunja, the self-hosted to-do server. Smart lists, widgets, a focus timer and offline sync. Open source (MIT).
A polo timer. One tap starts a chukka with warning bells. Game mode adds teams, handicaps and the score, and spectators can follow along in a browser.
Pub Meeting as a Service. An API that generates legitimate-sounding business meeting names. Pop a "Quarterly Pint Review" in your calendar and nobody questions where you've gone. Tested, MIT, faintly ridiculous.
A Home Assistant integration that pulls your TickTick projects and tasks into HA and fires events you can automate on. I've since moved to Vikunja, so it isn't actively maintained.
I build small software I want to use myself, and lately some hardware too.
The apps are Swift, because I like software that feels at home on the iPhone and doesn't nag. The servers are Python, running on a homelab that's bigger than one house needs.
When I'm not at a keyboard I'm usually on a polo pony, which is where ChukkaTimer came from.
