LWIP integrates quite well with the FreeRTOS scheduler, I’ve used that combo before. How does the “plus-TCP” stack compare?

It’s always baffled me that the default configuration of conda takes the liberty of contaminating the default shell environment. It feels incredibly bold to assume that because I install conda I want it to exist in every context in which I

Yes, we used them for a rocket launch in the desert. The main distinguishing feature is that these (CF-31 and related) are fully dust proof, the fan of a normal laptop will pull in dust and die. These were certainly slower to use, but we we

Don’t be afraid to implement a basic buck converter! Something like the MPQ4572 isn’t too hard to get right (right enough for hobby projects at least).

I'm sure this will find use in Business-Class "Mobile workstations", but having integrated DDR4 in my own hardware, I have a hard time seeing this as the mainstream path forward for mobile computing. There's lots of valu

To get good efficiency from a solar panel you must continuously track the “Maximum power point” (MPPT). You would never want to run a motor directly off the solar, you want a power converter to maximize efficiency.

This is cool, but if you want to see the proper extension of this style of computer, check out a Panasonic CF-31 Toughbook. They can be had for pretty cheap on eBay, and are amazing. In every way the opposite of the cost-cutting and cheap m

Maybe one day, but I’ve asked the various models basic EE interview questions, and it’s painfully obvious that while it can make a paragraph that has the right words, it’s incapable of reasoning spatially, or describing complex connections.

Hey, I’m very curious if you’ve seen any improvement in latency over the past month.

Unfortunately, the routing to make this feasible doesn’t exist yet. Users need a single IP address from a range that’s homed at a single PoP. Starlink doesn’t support user-user connections through the mesh, you need to go all the way out to

The US State department provided specific authorization empowering telecom companies (incl. Starlink) to operate in Iran and disregard local restrictions. If you can smuggle a dish into the country, you can use it. But the signal wouldn’t b

That’s a pretty significant jump in complexity, the RK3588 is one of the most powerful SOCs available. A cool part, but I’m not sure it fits the OpenWRT use case

You can get a pretty high quality PCB built at Bay Area Circuits in Fremont, and assembled at Sierra in Sunnyvale. The speed is marginally slower than JLC, the cost is marginally higher and quality marginally lower than Compeq. But, you can

Active probes can draw several watts. Probably shouldn’t, but no one is optimizing them for efficiency

The analogy doesn’t hold because one of the hardest parts of this technology is building a device that can extract the optical energy as electrical energy, and dissipate whatever heat it generates. The power density of the fiber itself is e

Unfortunately because of spectrum rules it’s unlikely that cell plans will work outside of the regulatory coverage region.

Hah, that video really ticked me off at the time. Technically true, but only in the least meaningful way possible.

I was just thinking back to my childhood homelab days. We would go to the regional recycling center and back our car up to the E-Waste trailer. One of us would pretend to move empty cases from the car to the dumpster, while another would cr

I think you’re in an uncanny valley where you want to have those powerful search features, but haven’t realized you probably wouldn’t actually use them. For ubiquitous passives, the DK search has all the relevant requirements, and then I’m

A good way to handle the who-updates-the-updater issue is to use a triple partition updater. A updates B, and then B updates C, then C updates A. If anything about the new version prevents it from properly updating its neighbor, that neighb

I recently got a BetaFPV Cetus X Pro. I was considering a DJI Mini, but FPV seemed like a lot more fun than the well-engineered computer controlled flight. And the vehicle costs much less to crash and destroy.

Those things are all possible, but you’re not going to find it in a COTS product. The key terms in the link budget is directionality. If you use a phased array (like Starlink) or a parabolic dish, you can boost your range tremendously. This

Anyone care to recommend one of the two devices (Kobo Elipsa or RM2) mentioned? It appears the RM2 may have gotten more expensive since release? How is the relative build quality? Any key hardware differences to note?

Agreed with Hector, there’s so many bad-faith or misinformed opinions around this. They should probably be obligated to provide calibration tools. However, the risk of providing those freely is that it increases the street value for stolen
