JohnsonB, the person behind the studio, giving a thumbs up in front of his shelves of painted miniatures
The one person

Hi, I'm JohnsonB.

By day I'm an engineer working on safety-critical systems. At night I'm usually at the painting desk; the shelves behind me are the proof. I wrote the engineering apps because I was sick of chasing paperwork at the end of projects. The revision site started when my daughter had a Biology exam. The game is the one I always wanted to play and nobody had made.

There's no team behind this, just me. If something here has helped you, a coffee goes a long way toward keeping the free stuff free. Thanks for stopping by.

What I've been working on

Ancient Jungle Village

Terrain bundle · atelier

Eight Aztec-style temples and houses for 25 to 32 mm tables, ready to print at home. I also made magnet bases and toppers in nine sizes to go with them.

The Learning Cycle is live

September 2026 · engineering & education

77 courses for Years 7 to 12. Each one has a mock exam that's actually marked, plus maps with timelines and a key under every formula. It's free, and nobody needs an account.

How I work

The same habits at every desk

Do it properly

Every print gets cleaned, cured and checked before it goes in the box. The engineering apps ask for exactly what an auditor will ask for. It's the same fussiness either way.

Your data is yours

My apps save to your device and work offline. This site doesn't use cookies, and I don't track you or sell anything about you.

Give credit

I link to the official standards instead of copying them, and I credit the curriculum bodies. LanceDeck uses the game art already on your computer.

Straight answers

You email me and I answer, and the prices are upfront. If something is still a prototype, I'll say so.
