Lab and open source
Things I build to learn: apps, printable hardware, and (soon) silicon and kernel patches.
L1 · app
Trajekt
Turns bike and public transport trips into expense claims in Moneybird, booked each month with the right VAT.
L2 · app
Connect
A free web app that helps you grow closer to the people you love by asking meaningful questions.
- Four settings: friends, date, year end and work.
- 50 conversation starters per session.
- Works offline by design, because you can’t truly connect while you’re online.
L3 · open-source
GitHub
Open source tools and experiments. Highlights:
- Flow Launcher ChatGPT plugin (55★): ChatGPT straight from your launcher.
- notion-auto-ocr (50★): automatic OCR for images in Notion.
- TPS61220 boost converter: a small power board design.
L4 · hardware
Thingiverse
Practical parts, designed in Tinkercad and printed on an Ender 3 Pro:
- a wall mount for the Lenovo Tab M8, the most liked design with 59 likes
- a retrofit for IKEA smart blinds
- a smart retrofit doorbell
L5 · silicon
Tiny Tapeout
Designing a small digital circuit to be manufactured on a real chip through Tiny Tapeout’s shared shuttle. It’s the next step down the stack, from PCBs to silicon.
L6 · kernel
Linux kernel
Learning the kernel’s development process, with the goal of getting a first patch accepted upstream.
