@CharlesMullins2 Breaking? Well no, it's the whole point of this tech!

🚨 BREAKING: Scientists just created a non-toxic, low-cost conductive polymer This could unlock a new era of biocompatible electronics Think about it • Circuits that move like skin • Implants the body doesn’t reject • Medical tech that feels alive We’re not just building better devices… We’re starting to merge technology with biology The line between human and machine is about to disappear Follow me I break down the future of physics, tech, and reality itself

@eevblog That's what happens when execs at big companies realize they are instants of being disrupted: they panic-buy a small company hoping they can outsource innovation

Liquid Instruments, the Aussie maker of USB scopes just got a $50M investment lead by Keysight to "accelerate a new class of AI-driven instrumentation." Great, I guess🙄 liquidinstruments.com/news-updates/s…

@eevblog Use a salad bowl and thin-foil to create a makeshift parabola, toss the 5g antenna in its center and point to the nearest GSM tower

Better 5G hotspot search time

@furan If it dissipates enough power it still is an LED though!

using one of these and putting a resistor on top

@i2cjak They did cut the PCB behind it. I'd have made the hole bigger though. Or maybe designed a slot antenna. youtu.be/dI6e4ZR9Oi8?is…

they… put the antenna in the center of the board…

@blind_via Or you could use solder paste jetting! With a little tweaking it could be fully automated assembly. For low-mid volumes it could be simpler than a fully custom enclosure and cheaper than manually assembled through-hole LED or light pipes

That probably doesn't fair very well in a convection reflow oven. Those look tall and likely to fall over. Plus you would have to manually past the top of the part.

@SawyerMerritt 10% degradation at 1000 cycles, so probably 20% (usually considered the point where it needs replacement) after maybe 1500? What's the point of having an EV with a battery that'll need replacement as often as a phone?

CATL, the world’s largest battery manufacturer, has unveiled its 3rd-generation Shenxing LFP battery. • 10% to 35% charge in 1 minute • 10% to 80% in 3 minutes & 44 seconds • 10% to 90% in 6.5 minutes. • Even at temps as low as -30°C (-20°F), CATL said it can recharge from 20% to 98% in as little as 9 minutes • CATL claims the new LFP battery can retain over 90% of its original health after 1,000 ultra-fast charging cycles • World-record internal resistance of 0.25 milliohms, ~50% lower than the average • New self-heating pulse technology for better charging performance in cold weather • New Cell Shoulder Cooling Technology, which is 20% more efficient “We always deliver what we promise,” Gao Huan, the company’s CTO, told reporters today at an event in Beijing.

@PhilippeLaban What I found works well is to use markdown split in chapters (ie mdbook). Easier for the LLM to target the right part to edit, and easier for me to review these edits

New paper! LLMs Corrupt Your Documents When You Delegate LLMs are enabling a new way of working: delegated work, where users supervise an LLM as it edits documents on their behalf. Delegation requires trust: does the LLM complete tasks without introducing errors? We simulate delegation across 52 professional domains and find that LLMs Corrupt Your Documents When You Delegate. 🧵1/N

@ptrschmdtnlsn Which EDA are you using? With Kicad roughly 50% of the parts I used needed 90 or 180° correction on their website. You just shoot and they'll correct?

@TareObjects Nah it's just doing an Ollie

JLCPCBのPCB AでBGA使ったら5枚中2枚不良orz 顕微鏡画像がこちらでございます。 浮いてるわーorz

@i2cjak Bangs-for-bucks king. But some parts are unubtainium

WCH-IC (WinChipHead btw) is the COOLEST Chinese semiconductor company SORRY ESPRESSIF! They make EVERYTHING. MCUs with motor drivers, USB-PD, high speed RISC-V chips, THEY EVEN HAVE BLUETOOTH BRO. Also SICK bridge ICs for USB, Ethernet. They also did that $0.10 RISC-V.

@brockpierson Crap drivers and no datasheet in sight.

First thing you think of when you see this

@IDV_FPV 0402 Good compromise of hand-reworkability, PCBA manufacturing process reliability and compactness

Since we’re already comparing our sizes… What’s your go-to passive size? 0201, 0402 or 0603? I’ll start: 0402. 0603 takes up too much space on the board, 0201 is a bit annoying to hand-solder, but 0402 is the sweet spot, easy enough to place by hand and still compact.

@willreil Either you can setup your inputs with internal pullups, and you can remove the resistors, or you're missing a resistor on the push button. (most MCUs have SW-controlled pullups in the 10k to 100kOhms region)

Does this rotary encoder look right to you guys? I have no clue what I am doing. I've seen some diagrams with another resistor between the GPIO but that seems unnecessary no?

@FurkanGozukara Good yield isn't guarantee of practical usability. What's the cost, what does this method depends on, how much existing pollution it removes and how much new pollution does it produce?

Massive geopolitical shift. NHK World confirms Japan has perfected a revolutionary process to extract high purity lithium from dead batteries with a staggering 90 percent recovery rate. This brilliant technological leap guarantees Japan's absolute economic security.

@observie Whatever the material, fumes and fine particles are all bad for your health. It you can't have the printer in its own, well ventilated room, at least have them enclosed with HEPA + active carbon filters.

PETG is nice: 1. It doesn't smell. Both ABS and PLA too honestly smell too bad for me to keep working in the same room 2. It's not as brittle as PLA. You can actually use it for some dynamic system testing 3. Better heat resistance than PLA: it won't warp or soften as easily I'm not sure why PLA is perceived as a beginner friendly go-to filament. I'd prefer PETG if only for the lack of smell

@joshuamschultz Process are this kind of asset of purely virtual value. Lose it? Your business stops. But unless you are at the forefront of technology, or in a highly competitive commodity market, your process isn't worth anything outside your company.

I know a manufacturer sitting on 10 years of custom CAD design reviews. Thousands of SolidWorks files with proprietary tooling data worth more than the building. The second they connect that to Claude, their data is on someone else's server. Possibly training the next model. We all have the same models. Every one of us. Same GPT, same Claude, same Llama. Your data is what's unique. Your process recipes. Your quoting history. Your scheduling logic. That's your moat. The smart ones are keeping it inside and running on-prem. Own your inference or rent your vulnerabilities.

@AnasYMalas @i2cjak Nice! Can you point it to me?

@chmousset @i2cjak There's a fork that I quite like, it's much faster and more full featured

JLCPCB has an API? Oh no it's a Java SDK. Oh wait I can LLM this into working. Python library in reply... This library can be used for: - Component search - PCB quoting/ordering - 3D part quoting/ordering - Stencil quoting/ordering I'm adding it to my build script for KiCad!

@ptrschmdtnlsn Marketeers would likely justify a higher price, making it unattractive unless you absolutely need a real perf boost. Then you need the CPU, cache, bus bridge, ddr controller etc.

I'm confused why Xilinx doesn't put a teensy tiny 800 MHz RISC-V or ARM core on every part. Like, why only for Zynq parts? It would cost almost no die area, and you constantly end up spending huge numbers of LUTs on a slow 200 MHz microblaze anyway.
