karmicthreat··on German Rheinmetall open-sources its Battlesuite connected weapon system protcol
This looks like ROS2 for missiles.
karmicthreat··on Electronic skin for prosthetics to sense temperature and pressure
There are already some products for arms that do this.
karmicthreat··on Can AI design circuit boards yet?
I had better luck recently. I’ve tried most of the commercial systems. None of them really got very far into the design.

Recently Radu over at Galvano.ai let me beta his platform. Way farther and way faster than anything I have used so far. Even managed to make the schematic placement sane.

The actual project was a regen clamp. So if the output voltage is greater than the input voltage (back emf from motor) you divert the excess to a resistor.

This has some analog tuning needed. So I created a python and skidl mirror of the netlist. This mirror was used to create ngspice unit tests to drive component optimization. Turns out not every resistor needed to be .1% and the ESR of our storage caps was a critical value.

All in all, it’s like ai and software. It’s not going to replace every job but will change how the jobs are done.

karmicthreat··on Anthropic appears to be A/B testing reduced effort levels in Claude Code
What’s currently the best pattern if I want to combine Fable and GPT if a workflow but keep using subsidized tokens?
karmicthreat··on Adafruit receives demand letter from Fenwick legal counsel on behalf of Flux.ai
I used company money on it. I was hoping I could massage it along enough to get a workable test fixture out of it. I wanted to put together a simple hardware-in-the-loop tester for a component of our product.
karmicthreat··on Adafruit receives demand letter from Fenwick legal counsel on behalf of Flux.ai
Adafruit probably did a review of AI PCB tools. I've used Flux.ai before; it was a pretty bad experience. After about 50-100$ in tokens a couple of times, I couldn't get more than a couple of simple components on the schematic. And not in sensible positions.

The product just grinds tokens for little return, in my opinion. I had far better luck wiring together KiCad MCP, SKIDL. There are some AI-driven autorouters out there now. Placement is probably the big issue that needs to be solved now. I could only get about 80% of what I wanted together with my hacky workflow.

karmicthreat··on ReBot-DevArm: open-source Robotic Arm
If you want something more industrial Chinese arms that ape UR are 10-20k.
karmicthreat··on A shift in developer culture is impacting innovation and creativity
I'm tired. I've been at it since '89' when I was 15. Everything being on fire all the time (in the world and in my current robot project) is just burning me out.

Most of my curiosity is tempered by how it can make me money.

I do appreciate that 50-70% of the boring work can be done with AI agents now. As long as you know enough to have opinions and guide the process along, it can be helpful.

Expertise and learning don't seem to be AS important with the upcoming gen of developers. However, there is also so much out there now that it would be much harder to start from zero as opposed to being there from the beginning.

But I think gen X and Millenials were probably peak interest and curiosity, now it's just a job for the later generations.

karmicthreat··on Tailscale 4via6 – Connect Edge Deployments at Scale
Is there a way to translate these into friendlier names? It would be nice if something like lidar-front.robot1.yada-fleet.bar could be made.
karmicthreat··on Ask HN: What are you working on? (April 2025)
I’ve been doing a lot of work with ros2 lately at work. Been seeing some moves with VLA models driving robots with text prompts. I think I’m going to focus more of my “free” time on mastering that technology.
karmicthreat··on SSH Keys Don't Scale. SSH Certificates Do
This seems kind of like teleport without the logging and remote infrastructure.
karmicthreat··on How to not build a two stage model rocket
https://www.youtube.com/bpsspace Does some pretty informative work with amateur rockets.
karmicthreat··on Ask HN: What are you working on? (March 2025)
I've been "Vibe Coding" this weekend with the vibe of a micromanaging tech lead or PM. Actually, it's not terrible if you just accept that you need to treat the AI like a year 0 engineer who is really good at googling.

I've run the project through cline and roo. Also tried Claude 3.7 and the 1M context Gemni 2.5 pro model. I'd say Gemini is less creative. But it's still good.

I can see how it is a productivity booster. Or at least it gives you the illusion of one. Really I think best part of it is just building out detailed documentation. That's really the killer app for me.

karmicthreat··on Lvgl: Embedded graphics library to create beautiful UIs
It's fairly nice just to build a simple embedded UI. There is also a useful editor now, though I haven't used it. It was implemented as a stand-alone program, I would have preferred a VSCode plugin.

It can be a bit difficult to get going on a specific platform, but once you have it going, it's smooth sailing.

karmicthreat··on NSA releases 1982 Grace Hopper lecture
What computer is Harper talking about here? https://www.youtube.com/watch?v=AW7ZHpKuqZg&t=375s
karmicthreat··on Tesla's self-driving tech ditched by 98 percent of customers that tried it
I think it’s just nudging the wheel that is going away. Attention detection via camera is still in effect for FSD. And it won’t start FSD without being able to see you.
karmicthreat··on Espressif Acquires Majority Stake in M5Stack
I'm not sure if this is good or bad. I use an M5Stack tough for one of my products. It works ok, but I really wish M5 had some more OEM friendly options.
karmicthreat··on Microsoft 'retires' Azure IoT Central in platform rethink
I need to make a little MQTT communications system for some field devices. I should probably just give up with AWS and Azure for IoT and just roll my own. Though they did have some nice security around their offerings.
karmicthreat··on Cybertruck owners say they're already rusting
My guess would be barring some metallurgical mistakes the stainless surface is getting contaminated during production. We do a decent chunk of stainless steel production where I work and we keep any tools that might be contaminated away from the stainless production. We also bead blast the surface and passivate it to keep it contamination-free. Just any little bits of non-stainless metal will corrode and permanently stain the surface.
karmicthreat··on Air Force OKs autonomous cargo flights across California after successful test
I'm sure the technology will work fine when everything is perfect. But much like autonomous cars, when things are imperfect they will probably start to fall apart.
karmicthreat··on Man who shoveled new channel into Lake Michigan convicted
There were other boat launches in Frankfort and Empire they could have used, maybe 20 minutes away. That river is not very traversable as it has a weir on it.
karmicthreat··on Lag in Cybertruck's drive-by-wire system
Seems like the same sort of whinging people do about traction control. “Trust me bro I need total control and traction control makes me unsafe” etc.

Same sort of thing with people that complain about iterm being too laggy.

karmicthreat··on Chrultrabook Docs
Same, now I want one.
karmicthreat··on Ethernet Is Still Going Strong After 50 Years
The one thing I would really like for ethernet is a smaller connector. But one that is still able to handle self-made cables. So something like just throwing a Type-C connector at it probably isn't going to work.
karmicthreat··on Man crushed to death by robot that mistook him for a box of vegetables
People have waaaay too much faith that motorized devices won't injure or kill them. Even motorized lie flat seats in an aircraft can probably break something. Many of these devices rely on simple current limiting. While this can help, its definately not a guarantee that it won't kill you.
karmicthreat··on Intel Itanium IA-64 Support Removed with the Linux 6.7 Kernel
I had a manager that loved these things. He would shoe horn eBay one’s into any gambling backend he did. It was terrible, impossible to support and made accomplishing anything a chore. Rust in peace.
karmicthreat··on Ask HN: What happened to hackerspaces?
They kind of came to be when the Bush financial meltdown happend. Unemployment was getting high in the late 00's. People were trying to develop new skills or build cottage industries. It feels like there is less of a hustle with all that now.

Plus makerspaces were just difficult to make viable and really you are probably better off spending that time on any other endeavor.

A group of us out here tried starting one in West Michigan and it sputtered along for a while. Financials and interest were never able to balance out. The Geek Group out here did a little "better" but the owners and volunteers there basically burned themselves out constantly. Then the founder got nailed for bitcoin crimes and that was the end.

karmicthreat··on TSMC tells vendors to delay chip equipment deliveries
China won't be able to unless they develop the tech domestically.
karmicthreat··on Ask HN: I’m an FCC Commissioner proposing regulation of IoT security updates
Has there ever been an example of a consumer RF emitter being remotely hacked and turned into a jammer?
karmicthreat··on What can I do as an amateur hacker to get the best programming job next year?
You don't really describe your background at all so all you are going to get is generic advice. But the best thing you could do this year is get a job in the field. Even if its not a very glamorous one you will learn more than you could in a bunch of tutorials or online classes.
