A motley collection of ideas
The module shown in the picture can be purchased online for around 2–3 euros. It is a small “15 kV” generator suitable, for example, for secondary-school science experiments or for use as a negative ion generator/air ionizer. The circuit can produce a stable, high-temperature, high-frequency arc, which can easily ignite small combustible materials, such as … Read more
Generative AI—like Gemini—has become an essential daily tool for researchers, engineers, and academics. However, its use comes with a recurring professional pain point: handling mathematical and technical formulas. If you ask the AI to derive a calculation or specify a physical range, the output will almost certainly arrive in raw LaTeX format (for example: $550 … Read more
How can we make 3D-printed grilles using Autodesk Fusion 360 and PrusaSlicer? A grille looks like a simple part: a few holes, a few ribs, done. In 3D printing, however, it is precisely with objects like these that we find out how differently the design program and the slicer think. For a flowerpot guard, a … Read more
