there's a funny thing with LLMs where FAANG had them in more-or-less modern shape for years but didn't push them because there was no product case, then OpenAI ran screaming naked into the street and they were like oh ok guess we're doing this

The best take I've seen so far.
DeepSeek mania is driving the AI world crazy. Is the bubble popping? are we now slaves to Chinese AI? is Nvidia over?
don't think so, no, and probably not www.404media.co/deepseek-man...

DeepSeek Mania Shakes AI Industry to Its Core

Ok, I've spent an hour and a half reading the talking heads' interpretations of the Deepseek/Nvidia hype.
So far, it is: "Deepseek did it cheaper, so buying will slow." 🙃
Erm, why will it slow? Foundation AI co's will not leave behind their HW edge - no matter what, more HW means faster research?

Someone help explain to me how this hurts Nvidia?
I'm not seeing it. In a gold rush where there is only one company not only selling the pickaxes, but the jeans, tents, and every other required tool to mine gold, how does someone using hardware more cleverly hurt the hardware manufacturer?

Only about 16 boards scrapped until I found a favored bit / tool diameter / cut depth, but the multimeter says it's good!
On to solder masking and drilling! 😁

Having an additive and a subtractive method of creating your own prototype objects is amazing. Sometimes I think I was born at exactly the right time 😅
Made a jig for the 70x100mm (actually - 71 x 101mm‼️) PCB blanks I've been buying.
Double sided tape was too squishy, and was causing problems!

Closer! Testing out all the steps here before solder masking and milling that away.
I did something wrong on the drill step 😬 but everything else came out pretty solid.
My process so far is: EasyEDA -> grbr export -> pcb2gcode -> candle + height map -> hit send

Using usbip to allow my rPi (attached to 3018 prover) to forward USB connections to my desktop, and from there, Candle to drive the CNC.
After trying several options, Candle's height mapping is amazing! I had up to .04mm variations in height that was absolutely wrecking my traces. Height map ftw!

Always wanted to try my hand at milling PCBs and milling away a layer of solder mask myself. Just got this setup using cncJS - my better half told me 12am was too late for any further testing 😅
Not saying I'm ready to call this success, but it is exciting 😁

Pro tip: verify the voltage out BEFORE you hook it up to your components 😬
Everything on that board just got rocked with 15v 😭 I've never seen every component pop the magic smoke all at once 🤣
That's what I get for assuming the V pin was of course 5v 🤣

@keithhanson.bsky.social I’m 💯 agreeing with you here. I’m training smaller and smaller models to be good at understanding the business data. This isn’t being run on massive cluster with GPUs but 12 year old ewaste that’s got just enough memory to run these models slowly.

Slowly but surely! 😁 FC picks up GPS and IMU just fine.
Hacking in my custom remote control via Steamdeck over Lora next! 😁

For anyone into custom FPV drone or ESP32 stuff, I'll be developing this weird monstrosity out in the open here: github.com/KeithHanson/...

Sooo, 48 hours of hyperfixation station, and I've learned that the drone FC software I was working with (esp-fc) - while awesome - basically tried to emulate a betaflight-configurable drone FC. Which is a fine approach if you just want an arduino/esp powered drone - and you get a lot that way.

I think I am way too excited about something so simple 😅
Never tried these sort of things before (always just soldered and shrink wrapped my wires or crimped dupont) but I needed 12 wires (drone motors) to be easily disconnectable.

So, I have this weird idea for a project that I have tried to ignore for the longest time. I'm putting it into the universe so I'll actually finish (and since I teased it in my initial commit.
I want a keyboard, but the halves are vertical. Googling split vertical keebs, think Clavert right?
