> use a $200 camera and photograph your keyring from a couple blocks away

Rayleigh criterion: to resolve an angle of 4E-6 rad (key bitting step is 0.015inch =~0.4mm , two blocks is 2 * 200ft =~100m), you'd need a ~140mm aperture lens. Can you really buy one (with a camera no less) for $200?

> When I put it into a 3d printer I also don't need the PSU

Unless you want your printer to power up on demand, then you need a separate PSU and an SSR (and you still need a buck converter because printers don't supply 5V at required amperage).

You can run Klipper on any Linux SBC with a USB port, RPi works but so does an old router that supports OpenWRT, a cheap Android TV box that could be flashed to run Linux, or any of the OrangePi/Banana Pi/Alliwinner H3 boards. You don't really need hardware UART because most of the printer boards you'd be using have either native USB or USB to UART converters. For that pedal, would an old Android tablet that supports USB OTG work? Because that's got to be much cheaper, and with much better SDK.

You tell me how to automatically sync photos across iOS+mac devices using non-Apple services. I'll wait. (hint: it's a monopoly, you can't use other services). Yeah, I know you can do a manual backup to e.g. Google Photos. It's not the same as seamless bidirectional sync.

> No highres 3d scan of your home being phoned back

You should look at a teardown of one of those sensors. It's a 1D lidar (if you can even call it that, until recently all of those were not ToF but more triangulation/reflection angle) being spun, no high res scans of anything can be achieved using that tech :)

Because drones without explosives strapped to them are so effective.. not to mention they spend 99.9% of the time in storage with battery disconnected, so easy to make a bunch of them attack at the same time (because once people know the drones are malicious it’s game over for the attackers).

pure idiocy.

I just use a unique address for each service. Any email that gets leaked or is getting unsubscribe resistant spam is added to /etc/postfix/denied_recipients :)

It has sleep current of 200microamps, so no longer than 40 days…

Blame STM. Those clones copy (..among other things) the naming convention from STMicroelectronics parts like stm32f103c8t6/stm32f103cBt6. Guess what's the only difference between those.

Oh, and .. since STM likes binning/product segmentation, there's a good chance that if you ignore the reported flash size and still try to flash the full 128K, it works on those models..

Treats are good and all but you will probably get better results with clicker training and splitting the job into simple parts. Fetch is pretty complicated and even dogs often have issues with it - our dog did just fine on the 'chase the toy' part - mostly due to strong prey drive - but then just ran away with it :). Took months to get it working.. Also cats usually lose interest quickly, so short sessions repeated more often will give better results.

This sounds almost word for word like The Onion’s classic: Secretary Of Labor Assures Nation There Still Plenty Of Jobs For Americans Willing To Outwork Robots

There are optoisolated mosfet modules available on aliexpress, or what exactly do you mean by “level shifters”? What’s your application?

Unfortunately, that doesn't really prevent companies from doing things being illegal if they turn out to be profitable enough. You could use a multispectral hidden camera and an mmwave radar fed into 'AI' to simulate a lie detector - you can definitely get pulse and breathing rate out of it, probably also perspiration..

Not the GP, but any supported BLE sensor [0] with a Bluetooth proxy ESPHome node should work.

ESPHome isn't really Espressif exclusive, there's Beken support already, which most cheap Chinese IoT gadgets use nowadays. And there are 'made for esphome' products which is a safer bet than buying Sonoff and praying the ESP32 inside doesn't have its secure boot bits fused.

As low as $10 if you all components are from JLCPCB's basic component library. For this board, more since there are some through-hole components and neither MCP4141 nor ESP32 (nor the buck modules used) are in the basic library.

It's there, but you have to configure a custom platform due to politics between PIO and RPI.

Thanks. Thinking more about that, might have been easier to just use 5V tolerant esp8266 :)

> there's probably something else on the other end of that wire that is doing modulation based on the sense resistance

And it would have been great if that arbitrary assumption had been tested by the OP and the results were documented in the article so that they wouldn't come off as somewhat clueless as to the limitations of their design.. oh well.

Why is there level conversion though if the digipot (MCP4141) is 2.7V to 5.5V?

Personally I'd just use breadboard, it's just a 8 pin IC and a ESP module, for a one-off hack..

There’s a Linux version of Resolve that works fine as long as you have NVidia and don’t mind transcoding m4a audio tracks to PCM (some codec licensing issues I think)

Southwest's 737 MAX contract had a penalty clause of $1 million per aircraft that would trigger if Boeing's delivery contract for the 737 MAX failed to meet certain standards, particularly Southwest's insistence that no flight simulator training be required for the MAX

Meaning, the roots of the “no new type rating” requirement come from Southwest, not Boeing.

I'm sure the SD thing works for you but some people need music discovery and open source options are lacking there. When you can set up a radio station backed by RED/Lidarr and not have your account go on ratio watch in hours, then we'll talk..

ESP32 has inherent sleep issues and before their latest chip (c6 I think) 'deep sleep' was really a gpio- or rtc- triggered boot followed by a power off. Doesn't mean it's impossible to implement wifi sleep efficiently, but if you do the math anything wifi based won't work off cr2032 for even a year unless daily updates is all you need. Motion sensors are supposed to fire more often, and with much less latency that can be done via WiFi, so it doesn't really work for battery powered sensors in the general case. You could probably use ESPNow and a custom gateway node but at that point it's just another custom RF protocol and you're better off with something standard like 802.15.4 or BLE..

> I've been burned by trusting Matter to mean broad compatability; my Aqara lock doesn't indicate how the door was unlocked over Matter despite showing up in their app, and this is after having to buy their Zigbee bridge because it won't connect to Zigbee devices from other brands.

Matter was made by the same guys that created Zigbee, proprietary vendor extensions are their bread and butter. Anything trickier than a contact sensor or motion detector, you should definitely research compatibility and definitely not update firmware once it works.

> I usually take my smart devices with me when I move.

Considering you can't even set up Matter devices if you lost the enrollment QR code (and the manual enrollment code is printed on the back of those ceiling downlights), it's a very good idea to take them with you and avoid frustrating the future occupants :)

Unless you're running Home Assistant and open source nodes. You can build a Matter+Thread node that works on a nrf52840 MCU, there are examples in the Nordic SDK. But then, why would you bother with Matter which is so bloated it doesn't even fit in flash properly? The only example that works on 52840 requires external flash to hold the B partition for OTA updates :)

So I'm using ESPHome for everything that could be wall powered and BTHome (with those same nrf52840 chips, you can buy boards for like $2 on Aliexpress) for everything that needs to run on battery.

“Siri, whose phone is this” doesn’t work on recent iOS versions. You could ask it to reboot, but that requires confirmation

There's literally a white list of permitted sites now, supposedly only to be used when there's a 'drone threat'. Guess what, there are places in Russia where there's a constant 'drone threat' for at least half a year and vk.com is basically all they can use to communicate. Why would they start arresting people for private VK messages now, while their 'max' messenger is still struggling? It could wait until all other messengers are less than 10% market share, that way it won't impede adoption until it's the only option available.
