No joke: Anyone else noticing the pricing rise in capacitors and even resistors?

Seems like there's been a significant uptick in pricing lately. I've read that there are industry shortages now for such basic parts. Who would have thought it?

I haven't bought anything lately, but saw a good discussion here:

@andriej Hi, I had problem using the main branch mysensors/Raspberry, that because of the bit-field struct (header_s) in Sensor.h They will get packed in different order on the arduino compared to the RPi (at least with my compiler, gcc). In order to fix this I created the 1.4dev branch. It uses full bytes instead of the bit-fields, but you need (of cause) to compile both the sensors (arduino) and the gateway (RPi) using the 1.4dev branch. We need to fix this in the main branch later on (and use the same files as in mysensors/Arduino/libraries/MySensors)

Are you still able to use the same analog phone plugged into the back of your modem? If so then it has to still use the same protocol, and I don't understand why the analog beacon wouldn't still work. It would just have to be on that same wire, not on the internet side of the modem. The modem is doing all of the translation in that case. Or am I missing something? Did you have to get a new phone to use the new service?

I don't have a good answer for you @mimaret When I get to the point where I'm getting strange error messages, I bite the bullet and start from ground zero. Fortunately, with the RPi you just need a new SD card. Start with a fresh copy of the Raspberry Pi OS. If you enable SSH (and WiFI) when you create the image, you can do everything headless (without keyboard-mouse-video) by running raspi-config via a remote terminal ( PuTTY ) If you enable VNC with raspi-config you can have access to the GUI. Double check your radio wiring. Don't have anything unnecessary plugged in. Carefully follow the instructions I've done this tedious process many times. My RPi's are 3B+ and Zero 2 W. Here's what I've encountered: bad power supply bad SD card bad wiring corrupt download and, of course, more user errors than I care to think about! I have not come across bad RPi ... no, not true! I had a Zero 2 W with a bad WiFi chip (common problem). Overcame that with a USB WiFi dongle. Good luck! Let us know what you discover. -OSD

@Tmaster I think it writes better code than a lot of code I've seen, and the documentation is a lot better. The latter, of course, is because most coders don't document. some key elements: good statement of work -- Purpose of the Code is key (did you write that? Good job!). This will guide the AI to write what you want. descriptive variables good documentation code is independent of reading sensors up-to-down/down-to-up I spent a couple hours analyzing, researching and writing and re-writing this and all I can say is that the AI didn't catch is, as far as I can see, if your sensors are too far apart or your magnet is too weak, you could get false readings. You, being the author of AI directive, are responsible for for the code. The AI is just a tool. I started my coding with assembly language, though at that time we still had to enter the binary on some machines (set 16 switches, then press commit). ForTran and COBOL were the first real high level languages and subsequent languages, pascal, c, java, etc. were improvements. AI is a quantum step. It's still coding, but you have to learn how to talk to the AI to get what you want. Good project! Let us know how it turns out and if you had to tweak the code. -OSD

It depends a lot on what you can do. As @OldSurferDude wrote, if you want a cheap solution, this is the way to go. Also when you need something that is not available on the market. Here below the list of my camper nodes. IMO mySensors is the best possible alternative, if not the only one, to the systems that rely on standards, which require way too many resources for the job they are asked. In my case, several nodes have edge capabilities, because they have to keep working even if the controller is not responsive.

@Homer I take care to say Good morning Sir, and Thank you Sir... You never know when it comes back to bite my tail.
