It's #Hackster round-up time, and hide your wallets because I'm once again starting with a crowdfunder: the Ampisu, a #RaspberryPi microcontroller-powered 7.5/15VDC dual-channel programmable PSU with third fixed 3.3VDC channel.
The bonus? A neat web interface, you can automate it via Python or SCPI, *and* you can upload CSVs and use it as a waveform generator.
This one comes with a disclaimer: I skimmed the original blog post this morning, loved the *concept*, and decided I'd write about it...
...then on proper read-through reached the bit about a chunk of the work having been farmed out to the Stochastic Parrot as a Service du jour, Anthropic's Claude. If I'd seen that this morning, I'd have moved on.
Assuming you still want to read about it, I present to you: Doom over DNS.
Finally, some #science with a look at ongoing work to build a solid-state ornithopter - a flapping-wing drone which doesn't have motors or gears or anything of the like, working instead on bio-inspired piezoelectric muscles.
The good news: a team has proven the design in simulation. The bad news: the piezoelectric material they'd need to build it... err, doesn't exist. Yet!
Unsurprisingly, all those are once again available via the #GeminiProtocol ad- and tracker-free:
