PINE64's new PineTime Pro:
gemini://tilde.club/~ghalfacree/202603/20260325-pine.gmi
And finally, a bit of a mixed bag from PINE64.
The good: there's a new PineTime in the works, the PineTime Pro - with battery-saving improvements, new features, and a shiny AMOLED display!
The bad: PINE64's suffering, like everyone else, from the AI bubble's insatiable hunger for RAM, so production of all the non-wearable stuff like phones and tablets has been halted. What's in the store now is it, folks!
Then the Canute Scientific, heading to @crowdsupply in the near future: a 13" laptop with a built-in refreshable Braille display, designed to provide "parity of display" to scientists with visual impairments. Again, #OpenHardware and #RaspberryPi powered!
An early #Hackster round-up today, as I'm actually ahead of the game for a change.
First up, a lovely #RaspberryPi-powered 3D-printable pocket camera - yes, yes, another one, but this one's got a twist: in-body film emulation, processed entirely on-device. (And it saves the RAWs as well, so you can easily undo it if you change your mind!)

Unsurprisingly, all those are once again available via the #GeminiProtocol ad- and tracker-free:

A simulated solid-state ornithopter:
gemini://tilde.club/~ghalfacree/202603/20260324-birb.gmi
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!
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.
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.
"Is this worth covering," my editor asks me. Click through to the LinkedIn (ugh) post, which opens "Vibe coding..."
I have never closed a tab so quickly. Hard pass, now and forever.
