Featured exhibits

The ones people stay on longest. Each opens into a diagram you can drive yourself.

Featured exhibit 01

How Does a CPU Work?

A CPU fetches instructions from memory, decodes what they mean, executes them, and writes the result back — billions of times per second.

Depth levels: 4
Quickest read: 3 min
Simulation steps: 4

Open exhibit Take the challenge

Featured exhibit 02

Why SSDs Feel Instant

An SSD has no spinning parts. It stores charge in flash cells, and a controller juggles erase blocks, wear levelling and garbage collection to keep everything fast.

How Does a CPU Cache Work?

A CPU can execute an instruction in under a nanosecond, but reaching main memory takes around a hundred. Caches are the small, fast copies that hide that gap.

How Wi-Fi Carries Data

Wi-Fi is radio. Your data is modulated onto carrier waves, transmitted in tiny time slices across shared channels, and reassembled at the other end.

Everyday Tech4 levels

How a Camera Captures Light

Light passes through a lens, is focused onto a sensor, and each pixel converts photons into an electrical charge. Aperture, shutter and ISO set the exposure budget.

Reading about a machine is not the same as understanding it.

Techseum is built on one idea: you understand a system when you can watch it work, take it apart, and change one variable at a time to see why it matters.

01
Pick a depth
Every exhibit offers four levels, from a plain-language intro to a deep dive with the real engineering constraints.
02
Turn it in your hands
Switch between a stepped 2D diagram and an explorable 3D model. Select any part to read what it does.
03
Break it deliberately
Open the exploded view, run the simulation at 4x, change the values in a lab bench and watch what happens.
04
Prove you got it
A short challenge at the end of each exhibit, worth XP and progress toward a badge. No grades, no timers.

Inside RAM

Random access memory holds whatever the CPU is working on right now — and it forgets everything the moment power is cut.

What Makes a GPU Different?

A GPU trades per-thread cleverness for thousands of simple threads running at once — the right shape for images, physics and neural networks.

How Bluetooth Stays Connected

Bluetooth is designed for short range and tiny power budgets. It hops between frequencies, keeps a strict schedule, and negotiates exactly how much bandwidth each service needs.

Electronics4 levels

How a Battery Delivers Power

A battery is a controlled chemical reaction. Lithium ions shuttle between two electrodes, and the electrons they leave behind travel the long way round — through your device.

How Touchscreens Sense Your Finger

A capacitive screen maintains a grid of tiny electric fields. Your finger disturbs them, and the controller works out where by measuring which intersections changed.

What Is Inside a Smartphone?

A phone is a stack of specialised systems sharing one battery: a system-on-chip, memory, radios, sensors, battery and display, all communicating over shared buses.

How Neural Networks Learn

A neural network makes a guess, measures how wrong it was, and adjusts millions of internal weights to be less wrong next time — repeated until the guesses are useful.

What Is the Cloud, Really?

There is no cloud — there are buildings full of computers. What we call the cloud is software that spreads your work across many machines and makes them look like one.

What do you want to understand today?

13 exhibits, four levels each, and a lab bench for every idea that is easier to feel than to read.
