Next-gen battery electrolyte made from wood offers record conductivity

Today’s lithium batteries commonly use a liquid electrolyte to carry ions between the two electrodes, but scientists eyeing solid alternatives see some exciting opportunities ahead. Among them are the authors of a new study who have used cellulose derived from wood as the basis for one of these solid electrolytes, which is paper-thin and can bend and flex to absorb stress as the battery cycles.

How to Overclock The New Raspberry Pi Zero 2 W – 1.3GHz All Cores

In this video I show you how to overclock the new Raspberry Pi Zero 2 W! I go over two different ways of overclocking first all on the Pi Zero 2 and second from a different PC. I recommend a heatsink of the Flirc case for the Pi Zero 2 W when overclocking but this defiantly helps out with performance! The Stock CPU speed on the Raspberry Pi Zero 2 W is 1.0GHz but we can easily overclock to 1.3GHz.

Befinitiv’s Latest Raspberry Pi Build Brings a Classic Super 8 Cine Camera Into the 21st Century

This clever — and non-destructive — upgrade adds digital capabilities, including streaming, to a classic of home cinema.

Pseudonymous maker “befinitiv” has once again designed a digital upgrade for a classic film camera, this time refreshing an old Super 8 cine film camera with a Raspberry Pi Zero W.

“Nowadays [Super 8 cameras] are almost unusable right now, because these cartridges are really hard to get,” befinitiv explains in the project’s video, brought to our attention by Adafruit. “You can find them still, here and there, but shooting one roll of film will cost you roughly €60 (around $70) — and this is €60 euros for three minutes worth of poor quality video.”

Raspberry Pi Zero 2 W

Just as small. Five times as fast.

At the heart of Raspberry Pi Zero 2 W is RP3A0, a custom-built system-in-package designed by Raspberry Pi in the UK. With a quad-core 64-bit ARM Cortex-A53 processor clocked at 1GHz and 512MB of SDRAM, Zero 2 is up to five times as fast as the original Raspberry Pi Zero.

Wireless LAN is built in to a shielded enclosure with improved RF compliance, giving you more flexibility when designing with Raspberry Pi Zero 2 W.

All in the same tiny 65mm × 30mm form factor.

Clever #Halloween Hack Uses Sound Waves to Simulate a Spooky Doodling Ghost

There’s really no wrong way to decorate for Halloween. It’s the effort that counts, even if all you do is toss some pumpkins on the porch, or set up an inflatable witch on the lawn. But there are those that go above and beyond the call of duty, like Dan Beaven, who leverages some cutting-edge levitation tech to make it look like ghosts are actually real.

New agricultural robots kill individual weeds with electricity

Small Robot Company (SRC), a British agritech startup for sustainable farming, has developed AI-enabled robots – named Tom, Dick and Harry – that identify and kill individual weeds with electricity. These agricultural robots could reduce the use of harmful chemicals and heavy machinery, paving the way for a new approach to sustainable crop farming.

The startup has been working on automated weed killers since 2017, and this April officially launched Tom, the first commercial robot currently operating on three UK farms. Dick is still in the prototype phase, and Harry is still in development.
