My issue is that a large share of what he tests are Amazon products with alphabet soup brand names, where QA is likely nonexistent and the conclusions are often based on a sample size of N=1. Even if you wanted to buy the "winner", the exact same product may be sold under a different name a week later.

I also find his testing methodology inconsistent. In some cases he takes manufacturer specs at face value without actually verifying them, in others he goes out of his way to comprehensively measure things that don’t matter much (to me anyways), while skipping things that seem genuinely important (self-discharge of jump starter packs for example).

That said, he's doing this with his own time and money, and makes it available for free to anyone. A lot of this also comes down to personal preference in what you value in a test.

The last time I worked with them there also was basically no way to render them into any other format easily, and all the available tools I found basically just launched a Chromium instance to copy each frame, messing up transparency in the process

Even with AOT compilation, as someone who loves C# and also does embedded development in C I would personally say a garbage collected language like C# has no place there.

Every time it has happened to me the airline paid out quickly without any fuss. Once with KLM the plane broke over Siberia, they flew back and put me on a flight the next day. I got my 600 eur compensation and also the cost of two train tickets for the extra trip between home/airport and they didn't even ask for receipts.

For the longest time Ryanair actually gave me more money than I spent with them on tickets.

What happens when software is at 0%, your slider is at 100% and you want to raise the volume?

That doesn't seem unusual to me, given that to get to this page you either have to be searching for the specific terms already (and know what they are) or come from the homepage -> RP2040 (Raspberry Pi Pico) projects -> Custom serial bootloader for the RP2040 -> Preliminary reading RP2040 boot sequence

My ISP gives me both an IPv4 address and a heap of IPv6, most browsers will use what is called Happy Eyeballs to try both IPv4 and IPv6 at the same time and use the one that connects the fastest.

At least in Europe I've seen plenty of thermostats/boilers that support OpenTherm which allows the thermostat to set the boiler temperature instead of only switching on/off

They are if you have anything else that needs to be done at the same time. I would say they're fine if you have nothing else to do while waiting, or you need microsecond delays to generate a signal like in this case.

You can get randomly selected upon checkout where they will sample a few items from your bag, and if it finds a discrepancy they will rescan every item you have.

These hand held scanners have been a thing for over 10 years, way before the current iteration of self checkout stations. They continue to exist side by side with self checkout stations at supermarkets mainly.

It also should be noted that I have not seen a single self checkout station in the Netherlands that puts restrictions on how you scan your items. It doesn't care about weight and in what order you scan and put items into your bag or if you just keep holding the items, and I never have any issues with this system breaking or complaining about anything.

At least for the lighting related concern, I personally use both Zigbee bulbs and switches. These can be bound together so the switch will directly tell the bulb to turn off/on without intervention of anything else. This results in a faster response and working light switches even when home assistant is down.

Or the power supply is sourced from multiple vendors, and other units might not have the same range

> Note that Watts, in general, goes down (not by a lot, and not at every voltage, but generally, linearly) as Voltage goes up...

I would say it flattens out pretty quickly and doesn't keep going linearly. This probably has to do with the fact that the device was designed to be powered from 12V so the supporting components of the power supply would have been chosen to maximize efficiency around that input voltage.

EDIT: I was curious and had a WRT54G v2.2 laying around (unlike the 1.0 used by OP), which results in this graph: https://i.imgur.com/CBNTtRI.png The lower power usage can probably be explained by my later revision having less LEDs and more integrated chips instead of several discrete ones.

USB defaults to 5V, so depending on how much current you want to draw you might not even need a trigger module.

I'm on the regular stable Chrome build and was explicitly asked on several devices over the last few months if I wanted to enable memory saver or not, it wasn't automatic for me at least.

Missed this comment when asking why you didn't add a $2 RTC, but given that you mention Adafruit I assume making your own hardware to stick onto a Pi wasn't an option? The DS3231 you mention is a chip with mainline support since 2009. Cheaper options like a DS1307 cost less than a $0.50 a piece when you buy 100 of them, and they've been supported in Linux since 2006.

If you were already going through all that effort, what was the reason behind not just adding a $2 RTC to the i2c header of each Pi?

I pulled up the actual USB power delivery standard[1] USB_PD_R3_1 V1.8 2023-04.pdf, and 5V 5A is perfectly compliant, albeit optional.

On page 805 you find Table 10-2 SPR Normative Voltages and Minimum Currents, which specifies that a USB PD source with a rating of 15 < x ≤ 27 watts *shall* support 3A at 5V, however it *May* advertise up to RoundUp (PDP/Voltage) to the nearest 10mA. Requires a 5A cable if over 3A is advertised. 27W/5 rounded to the nearest 10mA comes to 5.4A
