Good idea: turn motion into electricity, lead free

https://techxplore.com/news/2025-11-soft-hybrid-material-motion-power.html

Scientists have developed a new material that converts motion into electricity (piezoelectricity) with greater efficiency and without using toxic lead—paving the way for a new generation of devices that we use in everyday life.

Based on bismuth iodide, an inorganic salt with low toxicity, the new soft, hybrid material rivals the performance of traditional lead-based ceramics but with lower toxicity and easier processing. It contains no lead compared to existing high-performance alternatives such as PZT (lead zirconate titanate), which is 60% lead, and can be produced at room temperature rather than 1,000°C.

Special thanks to @sendhelporcaffeine for trusting me to bring their amazing protoframe OC to life! This character is theirs, and it was an honor to create art from their vision. Excited to see their story unfold in the Starfinder Warframe one-shot!

Someone walking past a sail in Kinsale made for a nice slow-motion intentional camera movement photo.

A cycloidal pendulum - one suspended from the cusp of an inverted cycloid - is isochronous, meaning its period is constant regardless of the amplitude of the swing. Please find the proof using energy methods: Lagrange's equations (in the images attached to the reply).

Background:
The standard pendulum period of \(2\pi\sqrt{L/g}\) or frequency \(\sqrt{g/L}\) holds only for small oscillations. The frequency becomes smaller as the amplitude grows. If you want to build a pendulum whose frequency is independent of the amplitude, you should hang it from the cusp of a cycloid of a certain size, as shown in the gif. As the string wraps partially around the cycloid, the effect decreases the length of the string in the air, increasing the frequency back up to a constant value.

In more detail:
A cycloid is the path taken by a point on the rim of a rolling wheel. The upside-down cycloid in the gif can be parameterized by \((x, y)=R(\theta-\sin\theta, -1+\cos\theta)\), where \(\theta=0\) corresponds to the cusp. Consider a pendulum of length \(L=4R\) hanging from the cusp, and let \(\alpha\) be the angle the string makes with the vertical, as shown (in the proof).
