Interactive exhibit, analog CRT television
From plug to picture
See live how electricity turns into a picture, in 3D, step by step, grounded in technical sources. ElectronTrail is an interactive 3D simulator showing how an analog CRT television works: current, signal, synchronisation, colour and picture.
Look inside the flow of electricity
An interactive simulation in four modes: a conductor cross-section, alternating current, a first-person flight and a zoom all the way down to quarks.
Step inside the picture tube
A guided walkthrough in six steps: power, signal, synchronisation, scanning, phosphor and picture, with an NTSC / PAL / SECAM switch.
The same leap, different devices
From a continuous signal to a stream of bits. CRT television versus digital, VCR versus DVD, turntable versus CD.
Five steps from plug to picture
- Plug it in: mains power reaches the receiver.
- Power flows: the power supply builds its voltages, the flyback builds the EHT.
- Signal comes in: tuner, intermediate frequency, video chain.
- Timing circuits: synchronisation, colour, beam deflection.
- A picture appears: everything comes together as an image on the phosphor.
Six modes, one subject
A first-person 3D journey, a waveform lab and a failure simulator.
