HolterTek

Independent engineering & design studio · Oslo, Norway

Powerful software, tailored design and creative solutions

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

Vision & motivation

Built carefully, shared openly

Four convictions run through everything that leaves this studio.

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

Things built here

A studio in two rooms: engineering products, and free learning tools.

Products — Eureka Engineering

ProductGearsComing soon

Vismut Studio

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

Projects — Eureka Learning

ProjectChemistry

S.A.M.A. Studio

Simulation & Analysis of Molecular Architecture. Build atoms, let them collide, watch molecules form under real physics.
