Independent maker Hardware,
software, 3D prints, podcasts

Ten years turning Arduinos, resin, and late-night ideas into things that shouldn't really exist. Open write-ups on Hackster and Instructables, shipped apps on GitHub, painted 3D prints on the shelf.

Things people ask

Who runs diyfunproject?

An independent maker working between Luxembourg and rural France. Ten years of open hardware and software projects, posted under the handle diyfunproject on Cults3D and Instagram, thomassxt on Hackster and Instructables, and daitenkutarojurai-ai on GitHub. Cumulative reach across write-ups: 100,000+ views.

What kinds of projects do you build?

Five buckets:

  • Hardware — Arduino & Raspberry Pi automation (espresso machine over Bluetooth, photobooth on Pi, cocktail dispenser, automated greenhouse, IoT smart plant).
  • Software — mobile games (Chess Kombat), gamified IT-cert trainer (Cert Quest), web booking platforms (Salon V1), weather-aware dashboards (Crêpe Forecast).
  • 3D design — original chess sets and figures designed in Fusion 360, published as free STL packs on Cults3D.
  • Books — self-illustrated children's stories.
  • Podcasts — cloud / DevOps audio companions for AWS, Kubernetes, Terraform, Git certifications.
Where can I download the STL files?

All original chess sets and printable designs are on Cults3D · diyfunproject — free downloads. Featured packs include Chess Shot, Freemason chess, and the 4-player Chaturanga set.

Where do you publish full build write-ups?

Two main outlets, both with parts lists, code, and step-by-steps:

Code lives on GitHub · daitenkutarojurai-ai.

Are the podcasts free?

Yes — all six are free on Spotify. They're cert-prep audio companions for AWS Solutions Architect (SAA-C03), AWS Cloud Practitioner, KCNA Kubernetes, GitLab Certified Git, HashiCorp Terraform Associate, and a general Cloud Engineer Bootcamp covering AWS · Kubernetes · Git.

How do I get the most-recent updates?

Three places. New write-ups land on Hackster and Instructables first. In-progress shots and bench photos go on Instagram. The News page aggregates the broader maker-world feeds I follow and refreshes every time you visit.

Can I commission a build or use your STL designs?

Yes — for commissions and licensing questions, use the contact form. STL packs on Cults3D are free for personal use; check each pack's license for commercial terms.

About

Ten years of making things in public

Based between Luxembourg and rural France, I publish open-hardware projects and apps primarily on Hackster and Instructables, with recent additions on GitHub and the Google Play Store.

The through-line: take a familiar object, give it a brain, put it online, documenting the process. Cumulatively those write-ups have reached over 100,000 views.

Day job — System & Network Engineer | DevOps with six years across enterprise Linux/Windows in demanding sectors: aerospace (ArianeGroup), banking (Société Générale), and automotive (IEE, current). AWS Certified Cloud Practitioner, LPI Linux Administrator, with hands-on Ansible, Kubernetes, Docker, Terraform, and CI/CD.

Off the keyboard — chess, climbing, diving and free-diving. The Arduino, Raspberry Pi and 3D-printer benches do the rest.

Many thanks to the following contributors

Luc (my father) — 3D printing and painting of numerous components on this site. Hours at the bench I didn't have.
Gilles Miara — design collaboration on several 3D pieces, improving shape precision.
