Fatherhood — The Personal Thread Behind the Technology

Between the server logs and bicycle builds, there's a father writing about what actually matters.

Most of Willem's blog is about technology, bikes, and building things. But the posts that people remember longest are the personal ones — the ones where fatherhood, health, and family break through the surface. These are fewer in number but deeper in impact.

Behind every post about servers and sensors, there's a father. The cargo bike isn't just an engineering project — it's how the kids get to school. The health sensors aren't just data — they're peace of mind for a parent managing a rare condition. The move to the countryside isn't just lifestyle — it's about what kind of childhood you want to give your children.

MCADD

The most personal post on the entire blog. Living with MCADD — a rare metabolic disorder that affects one of Willem's children — is raw, informative, and written to help other parents who find themselves in the same situation. It explains what MCADD is, how it shapes daily life, and why Willem started wearing health sensors in the first place.

Thoughts and tips on the daily life as parents

Tomorrow it's six months since our son was born, a good moment to reflect upon the experience of being a parent of a kid with MCADD. This metabolic condition demands special attention on the feeding schedule and preparation for situations when things go different. It's good to share that this has quickly become normal for us, here are some thoughts and tips.

The Big Decisions

Moving to the countryside — leaving Amsterdam after years of city life. It's a family decision, written with the honesty of someone who loved the city but needed something different for his children. The cargo bike build connects directly: it was built to carry kids.

Leaving the big city for a small village

This month marked "the big move": relocating my family from Amsterdam to Noord-Limburg's countryside. Motivated by my wife's longing for her roots and our desire for space, the timing felt right. As our oldest child neared four years and primary school, we considered embracing the countryside lifestyle. Would trading Amsterdam's bustle for a new pace be rewarding? Read on!

Setting up the Babboe Big cargo bike

This month our Babboe Big cargo bike arrived, in boxes. The engineer in me thought it was a good idea to assemble the bike by hand. This way I would know exactly about all its parts and fittings, handy knowledge for maintenance. Read along for my experience and some practical tips.

The Quiet Moments

Not every personal post is about big decisions. Harvesting boredom is about creativity and parenting — letting children (and yourself) be bored enough to make something. The posts about selling the car, about festivals, about the daily bike commute — they're all shaped by the reality of being a father in a Dutch city.

Looking back at my years with Smart Roadster

This week I sold my car, I now no longer own one. For me, this is something of a change as over the years I owned various sports cars that were like a hobby to me. My discovery of cycling and the birth of my son changed this. But if you're looking for a reason to buy a sports car, read along!

using the Punkt MP01 dumb phone

Smartphones are everywhere in the modern society we live in today. Through our 4G and WiFi connections the internet is just one tap away. In fact, it is so close that it feels like a natural extension. But is this wealth of information all good or does it have a downside too? It seems like an interesting experiment to go app-less for a while and solely use a dumb phone.

The Thread

Fatherhood doesn't get its own section in Willem's blog navigation. It doesn't need one. It's the thread that runs underneath everything else — the reason the cargo bike got built, the health sensors got worn, the move to the countryside happened. Technology serves life, not the other way around.

Trail Running

Trail Running

Through mud and nature

Doubling my daddy duties with my love for endurance sports, I decided to take advantage of me living in the countryside and run to the store through nature, following local creeks and trails. It's a unique experience, I may even like it better than normal running, let me explain.

Hello Video

Hello Video

Greeting you with a smile!

Just look around the modern web today, thanks to AI generated texts and images everything feels polished, perfect... and a little cold. I wanted to break the proverbial ice with a simple smile. So I replaced my hero photo with something alive: tiny, random videos of me waving, nodding, or just being there. There is more than meets the eye to make it work, let me explain in this post.

On Fairies and Gin-Tonic with Blueberries

AI got me thinking lately, why would one still want to work? Perhaps today's imperfect AI is not ready yet, but imagine everybody has access to a near perfect intelligence, capable of solving hard problems and answering even your wildest questions. Combine that with robotics and we'll be left wondering what to do next. Some fairies and Gin-Tonic pointed me to a possible answer.

Experience the world like a kid

Together with my kids I love to explore the world that we think we know as adults. A kid's perspective inspires and surprises! No need to travel half the world for an adventure: Fly planes, catch bad guys, solve problems, build and break stuff - (re)discover the adventure right at your doorstep!

Impact on daddy and his biometrics

Today I witnessed the birth of my daughter! You feel humble as a man, witnessing the labour and magic. Not sure if I can come up with something having more impact on a man than this. For the purposes of science and curiosity I wore a biometric sensor, and this is what it recorded.

Fixing the cargo bike after hunting for bears

Last week my son and I where looking for bears in the local park... a child's fantasy is priceless! Unfortunately, during some off road riding with our cargo bike, one of the cables got tangled up with a sturdy branch! Our wounded carbo bike was in need for a repair!

Medium chain acyl-CoA dehydrogenase deficiency

Just days after our son was born, we ran into trouble when our little man didn't want to eat anymore. Repeated attempts to feed him failed as he appeared to be too tired to drink from his mother. When we measured his body temperature we were shocked, only 33º Celsius! What followed was nothing less than an incredible emotional rollercoaster!

On the challenges and rewards of being a father

Last Christmas my wife gave birth to our son, a little boy that would change everything! It's an incredible experience to become a parent, especially if it is your first kid. It introduces a whole new way of living, having to deal with regular feeding, caring and sleepless nights. Read along for my (biometric) findings and some practical tips!
