Ooooh this is seriously cool The Helios Horizon’s previous lithium-ion pack delivered 260 Wh/kg (watt-hours per kilogram, a measure of how much energy a battery holds relative to its weight). The new solid-state cells hit 410 Wh/kg, a 60% jump. Chief test pilot and company founder Miguel Iturmendi expects that figure to grow another 40%…
This is a beautiful way to understand how the web works. I love the “scrolling” visualisation. https://translucentweb.site/
My first USB-C soldering iron was a revelation. “You mean I can make liquid metal connections anywhere, in seconds, just by plugging this tiny stick into a USB cable?” Now, repair company iFixit is introducing its own take on the idea. It claims the iFixit FixHub Smart Soldering Iron is powerful enough for pros and easier for beginners…
I’ve long maintained that RISC-V is one of the most exciting technologies of the future… we’re starting to see that future.
Terraform Industries is developing machines that create synthetic natural gas from sunlight and air. It sounds like science fiction, but the technology is rooted in simple chemistry and powered by the rapidly advancing field of solar energy. https://www.freethink.com/series/the-freethink-interview/casey-handmer I like the frame work of tackling the problem. Whether it’s the solution, time will tell. An…
The Pico 2 board retails for $5 and, according to the Pi team, retains backwards hardware and software compatibility with previous versions. While the on-chip memory has been upped to 520KB – there is also 4 MB of on-board QSPI flash – the two RISC-V Hazard3 CPU cores included in the microcontroller may well interest…
I totally love this! A joule thief is a sort of minimum-component voltage booster that can suck nearly every last drop of energy from even seemingly-drained batteries, and is probably most famously used to light LEDs from cells that are considered “dead”.
Yesterday’s computer problems mostly consisted of computation – using hardware to build fancier and fancier calculators. Typical uses for computers consisted of moon-shot calculators and military missile ballistics calculators. Today, though, the interesting problems are mostly asynchronous and distributed. For example internet, robotics, gaming, blockchain, GUIs, etc., etc. We need a new workflow which uses new notations…
