A standard catalogue model: the dimensions, control package and finish are fixed, which is what keeps the price and the lead time predictable. Size, colour and interface language can be adapted without a new design cycle.
Standard models from this range are also listed in our online store, priced in USD — see the price yourself ↗
The exhibit is shaped like a huge pendulum, with strong magnets below the pendulum rod, and strong magnets of different sizes distributed on three rotating disks. Pushing the swing rod, due to the attraction and repulsion between the magnetic poles, the swing rod begins to swing irregularly and drives the turntable to rotate irregularly.
The unit is designed for unsupervised public use: controls are recessed or shielded, moving parts are enclosed, and the interface is operable by a child of about six with no instruction. Where a screen is used, the language can be switched without changing the hardware, and the content can be replaced on site.
Every unit leaves the factory after a running test: mechanisms cycled, electronics burned in, edges dressed, fixings torqued and marked. Wear parts — bearings, sliders, lamps, belts, touch panels — are modular and listed on the spare-part sheet, so a venue technician can replace them without returning the exhibit. Crating is plywood with foam blocking; the loading plan and packing list travel with the shipment.
Other models from the Basic Science line, all held to the same specification and the same control package.

Rotate two polarising filters and watch colours appear and vanish.

Sand on a driven plate jumps into nodal figures as the frequency changes.

Coloured discs drain to grey as the spin speed passes the eye's limit.

Gas discharge tubes and a slit spectroscope show emission lines directly.
Attach a theme outline, a floor plan, or nothing at all — a photo of the space is enough to start. Quotations are issued against a real exhibit list, not per-square-metre guesses.
