I’m not getting this, at least not yet.

Maybe it’s because I run Pi-hole; I know it filters out a TON of Roku’s telemetry and other traffic. Might be worth setting up Pi-hole on your network and see if stuff like that goes away?

Mozilla’s “least to most creepy” ranking is the best resource I’ve found so far:

I mean, if a car doesn’t see a cyclist until the last moment, swerves to avoid it, and hits something else, the cyclist being there created a dangerous situation for the driver.

Even just considering a driver hitting a cyclist, the driver still has to live with that outcome for the rest of their life. Unless your expectation is that the driver is a psychopath who only cares about the condition of their vehicle, which I suppose is a possibility.

Respectfully, an article from four years ago that I cannot read in full without creating an account, which seems to just reference a calculator from FT that is over a decade old at this point (whose sources I also cannot seem to find) doesn’t impress me. Do you have anything more recent, preferably that sites sources, that you can share? I’m genuinely interested in what data is actually worth

Honest question:

If you feel these tools are essential and there are no other options (not sure I agree, but that seems to be the argument you were making; let me know if I am wrong), what is the alternative?

These things take money to keep the infrastructure running, pay staff, patch security vulnerabilities, and bring new features for those same communities to use. And they are also a public company, which means they have a legal responsibility to return money to shareholders.

I’m not defending Meta, I refuse to use their platforms and will not be buying any of their hardware. But if it takes money to keep the lights on (at a minimum), how does offering ads or a subscription equate to a false choice?

I also feel many don’t understand the full extent, either. They’re used to using fairly secure devices in their everyday life (often not realizing how much the software they install is also spying on them), so why wouldn’t these IoT things also be secure?

In my experience, it’s all very vague and ethereal until the risks are highlighted for them. “So what if Google can read all of my emails? What could they possibly do with that information, anyway; why should I care?” is an example of a portion of a real conversation I’ve had.

The original “clicker” remotes were really neat tech! The way it worked unfortunately limited the number of buttons you could have, but still ingenious.

Hey, that’s totally fair and I am definitely of a similar mindset when it comes to reducing e-waste.

Do you have any significant coding or hardware skills?

To add, I found a thread of someone attempting to find use in the same router. They seemed to have made some minimal progress over the last year, but it doesn’t appear they have anything functional yet. Seems the processor has little known about it, and there is precious little storage onboard.

I guess my first question would be: do you have a need that device can fill, or are you looking to take on a project for some other reason (education, boredom, etc.)?

I honestly don’t see to what great use a router (and modem) that was discontinued a decade ago can be put that couldn’t be accomplished with less complication and less power draw by using a modern device. I’m not trying to rain on your parade, but knowing nothing else about your situation I don’t know that I can see any utility in a device like that anymore.

That was a fun read, thank you.

 

I just watched Joe Scotto’s new YouTube video, where he walks you through the basics of setting up KiCAD and designing a simple macro pad PCB. I am actually super excited to use this knowledge to design my own stuff now!

 

Hello!

I've ventured far too deep into the custom ergonomic columnar-staggered mechanical keyboard rabbit-hole, and I think I've finally found myself at my endgame (for now, anyway lol): the Hillside 46.

TL;DR:

Please see "questions" section at the bottom regarding why, how, and if I should use the ESD protection on the right-half, left-half, or both halves of this split ergo-mech keyboard build.

Background:

In constructing this board, I came across a part of the circuit design that has confused my non-expert brain: the ESD chip and decoupling capacitors. At a theory level, I understand that it protects the board from electrostatic discharge (presumably, specifically, the microcontroller) and the damage it can cause. What is weird to me is that this is the only keyboard out of the several split-mech-ergo boards I've built that have featured this protection circuit, and even within the Hillside family of keyboards, the version with 46 keys that I built seems to be the only one with this protection circuit which makes the decision even more perplexing to me.

Given that this is a split-keyboard design with a reversible PCB, there are footprints for the SRV05-4 ESD chip (datasheet here) and decoupling capacitors on both sides of the PCB though they appear to be wired up differently depending on the side of the board you're using (schematic here). On the "top" of the PCB (left side of the keyboard), you would solder the ESD chip with pin 1 at the top-left position. I did this and everything works fine.

On the "bottom" of the PCB (right half of the keyboard), the connections to the pads seem to be mirrored from the "top" of the PCB, but it looks like that was done so in a way that would not allow me to invert the ESD chip, with pin 1 at the bottom-right of the footprint, and still have everything work. I definitely can't keep pin one at the top-left of the footprint on the "bottom" of the PCB, so I'm kind of stuck as to what to do.

Questions:

  1. Are the ESD chip and decoupling capacitors necessary or just nice to have?
  2. If they are necessary or very useful, do I really need them on both halves of the board?
  3. Looking at the Gerber file, it seems like I might be able to mount the ESD chip to the footprint on the underside of the right-side PCB and still have it functional; is that correct?
  4. What is this ESD circuit protecting against, exactly? I assume it's potential voltage spikes on lines that shouldn't have them that can occur if I were to unplug one end of the audio cable while the keyboard was still plugged into power/USB; is that correct?

Thanks in advance!
