Autonomous Robot Tank Eradicates Almond Pests with One Silent Shot

The autonomous Bolo tank tracked down the tree-lined lane looking for targets. Suddenly the Bolo’s tracks ground to a halt. Targets spotted. The Bolo’s two top-mounted turrets slowly swiveled as the AI system zeroed in. Up there. On those branches. The Bolo aimed and fired. Targets destroyed. The Bolo robot tank is a fictitious, autonomous, nuclear-powered war-fighting machine that first burst from the fevered … Read More → "Autonomous Robot Tank Eradicates Almond Pests with One Silent Shot"

The Currency of Data: Liquid Instruments’ Innovative Take on Software Defined Instrumentation

Software defined instrumentation takes center stage in this week’s Fish Fry podcast! Ben Nizette and I chat about how Liquid Instruments is changing the face of test and measurement. We examine each of their hardware platforms and investigate why this kind of flexible, modular, reconfigurable, and shareable instrumentation is the way of the future. Also this week, I check out the first commercially viable flexible plastic microprocessor chips … Read More → "The Currency of Data: Liquid Instruments’ Innovative Take on Software Defined Instrumentation"

RISC-V Takes Embedded World 2022 by Storm

I love computers (but only in a manly-man way, you understand). I’m not talking about the end-products that sit on our desks, hang out in our pockets, or lurk around us as we meander our way through the world, although I’m certainly fond of these little rascals—I’m much more interested in their “brains” in the form of their processing units where all … Read More → "RISC-V Takes Embedded World 2022 by Storm"

I Was Mr. Spock’s Science Officer, For a Day

I’ve been reading science fiction (SF) since the second grade. The first SF book that I read was “The Space Witch” by Don Freeman, which I promptly plagiarized. That book was published in 1959 and I read it a couple of years later. By fourth grade, I’d graduated to the Heinlein juveniles starting with “Have Space Suit Will Travel,” which psychically transported me out of my fourth-grade classroom … Read More → "I Was Mr. Spock’s Science Officer, For a Day"

Well -- the open-source part is a big one -- also the fact that RISC-V is being designed from the ground up based on all of the things we've discovered (and learned our lessons from) in previous processor designs. The fact that so many people are jumping on board -- ...

I don't disagree with anything you say -- your points are valid -- but... for reasons we don't need to go into here, I currently find myself using PICs for all sorts of things, and I'm finding them to be incredibly useful for what I need to used them for.

PIC was crap. Even mid-range PIC16 core is painfully limited ( PIC16F1527 and similar) Just one grief - both index registers are "shadowed". But instead of having two sets and just fliping them on interrupt entry, they get COPIED. Which means that no matter what, one has to regenerate them ...

Hi Max, your article brings up a conundrum I have had recently involving a proposal specifying a processor to be used in conjunction with an FPGA. I ended up selecting RISC-V processor IP to be used but really without a good reason why. Sometimes you go along to get along. ...

Sounds like witchcraft, or mumbo jumbo, which means it will probably feature in mobile phones and laptops within the next 5 years, lol.

Wow! This is an awesome story Steve -- how come I never heard about any of this before? You should have led with this when we first met LOL

I'm guessing the lights on the IBM panel were small incandescent bulbs. If I ever lay my hands on one of these panels, I'll have to decide whether to keep the bulbs or replace them with LEDs.
