HolterTek

// HolterTek — independent engineering & design studio · Oslo, Norway

Trustworthy software, tailored design and creative solutions

Tools built on real physics and websites designed to invite people in.


Vision & motivation

Right, not just convincing.

Tools are built on their governing equations and ship with test suites — so results can be trusted rather than eyeballed.

Teaching stays free.

A simulation a student cannot open teaches nobody anything. The learning work is free, and kept that way on purpose.

Public data, made usable.

Traffic cameras and transit positions existed separately for years. Putting them in one view turns two datasets into one picture.

Rigour and craft, together.

The engineering and the design use different muscles — and they sharpen each other.


Selected work

HT-01 Vismut Studio Product Gears

A gear design studio where the geometry is solved, not drawn. Seven families, live simulation, DXF export straight to CAD.

HT-04 Eureca Chemistry Lab Project Physics

Build atoms, let them collide, watch molecules form under real physics.

HT-05 Eureca Reactor Project Chemistry

A falling-sand reaction sandbox where the chemistry is real — 38 substances, 42 reactions.


Web design

Websites that answer the question people came with.

Design and build, from identity to deployment. Fixed price, agreed before anything starts — the number moves with scope, never mid-project.

// Case — Bøler Basket

A basketball club's site built around the one question every member opens it to ask: is there training tonight, and where. Identity, UI and front-end.

One-pager A single scrolling page, designed, built and deployed on a domain you own. Responsive from 320 px up. From 6 000 NOK1–2 weeks
Full site Up to six pages with identity work where one is missing, an editable content layer, analytics and two rounds of revision. From 12 000 NOK2–4 weeks
Design system Type scale, colour and spacing tokens, a documented component library, and handover to your own developers. By agreement

Rates are starting points — every project gets a fixed quote up front.
