A spiral of copper, an open view, and a frequency you can choose.
There is something irresistible about an instrument that lets you see a little of its own workings. The Spiral Board puts its patterned circuit at the centre of the design, with a clear shell that allows the electronics to remain part of the experience. It feels like a small piece of the experiment bench, rather than an anonymous sealed box.
The spiral is what catches my eye first. Then the display and controls bring the object into focus as an adjustable generator. For someone whose interest runs from the old resonators to contemporary frequency apparatus, this is an appealing meeting of visual character and a direct electrical idea.
A small generator with an open character
The module uses a 5 V Micro-USB input and sits within a compact acrylic shell, approximately 108 × 77.5 × 13.8 mm. That shallow format gives it a distinctly different presence from a substantial cased instrument. The board, its spiral trace and the small digital display become the visible language of the object.
The adjustable format is the point of interest here. A Schumann-frequency setting sits within a much broader fascination with low-frequency signals and the way they are represented by a physical instrument. The displayed setting and the actual electrical behaviour are different things to examine, which makes a little generator like this an absorbing addition to a measurement-minded bench.
Give the experiment a place on your bench
I would choose this for someone who enjoys compact electronics, visible circuit design and the pleasure of exploring an adjustable instrument. It has a different role from a vintage violet ray, yet it belongs naturally within the same wider curiosity about oscillation, patterns and electrical form.
Send us an enquiry about the Spiral Board and the frequency range you are interested in. We will confirm the exact board version, controls and included power lead. The appeal is in understanding the particular module you are choosing and giving it a proper place within your own collection of experimental apparatus.
