    Fun fact, making extensions for this requires you to learn a new language called X++ that is based on .net framework 4.7. Development is done only on azure-hosted VMs that contain the application code and sql server and web host and visual studio with the special X++ build tools, all on one host that runs like shit at your expense.





  • My first boss was a “just” guy. Thankfully he was also pro dev, being one himself, but sadly he was completely self-taught. This led to some interesting ideas, such as:

    “We should not migrate anything to, or start any new projects in, .net framework 3. We should become the experts in .net framework 2, so people who need .net 2 solutions come to us.”

    “Agile means we do less documentation.” (But we were already doing no documentation)

    “Why are you guys still making that common functions class library? I just copy a .vb file into every project I work on, that way I can change it to suit the new project.” (This one led to the most amusing compound error I’ve fixed for a fellow dev.)

    Good guy, all in all. But frustrating to work for often.










  • No problem. The one I used is an ESP32 DevKitC, and you can find info about it on Espressif’s site, or just google the pinout diagram. For basic tasks it should be all you need since it has lots of binary pins, two ADC channels, two DAC channels, realtime clock, special pins for waking it from deep sleep, two I2C, etc. Though if you want to do video input you probably want something else, I’m learning.

    Anyway, if you can spare the money to get one just to toy with I’d definitely recommend it.


  • Okay so that is an issue with the ESP32, sure. There are a lot of variants.

    So from what I can tell, the ESP32 is the SoC chip and what you usually get is a dev board which has that plus a bunch of power regulation bits, a USB connector and UART so you can easily program it, etc. That part varies mostly by pinout. I.e. Same features, different pin location.

    There are also variants of the chip, but those are usually more costly and will be named things like ESP32-S2.

    Every one I’ve seen can run off 5v or 3.3v and uses the latter for logic, so if you got yourself an arduino kit and then just bought an ESP32 dev board it would almost certainly work with whatever is in the kit. Both are microcontrollers, not microprocessors, so they tend not to have OSes or screens.



  • When you put mail in the box, unless it’s a REALLY small bit of mail it’ll land so it obscures at least one of the proximity sensors. This then sets the ‘got mail’ statue to ‘on’ in Home Assistant. From there, I have HA set up to send me notifications to go and check the mail.

    Before you say so, yes this was a lot of work for something so trivial, but it was fun. Plus I actually get so little physical mail that I can forget to check the mailbox for weeks at a time. Which would be very bad if I got some actually important mail. And actually, that exact thing happened just days after I finished installing the thing. So it has already potentially saved me from a fine.
