 I had a friend who once used wifi to connect a micro controller to an LED **on the same PCB** in one of his projects and I still make fun of him for it. (he didn't want to have a wire visible or run a path) I wonder if there are other instances of wireless communication within perfectly wire-able devices in the wild. Big Clive needs to be sent some of these monstrosities to take them apart! 8 comments
  @Affekt @futurebird @fraggle I was looking at kitchen scales recently and came across one that for some reason had Bluetooth. What's worse, according to reviews, it wouldn't even work at all unless paired to something despite having a display. I did not buy that one.  @mansr @futurebird @fraggle right after I started in the industry I saw furnace filters with BLE. I'm pretty sure they just start a timer when you pull the battery tab and remind you on an app when the timer is up. Like, set a calendar reminder and save some electronic waste. But my manager would kill for us to get into applications like that.   @futurebird @fraggle@octodon.social There's 60GHz radio links with tiny horns for doing datalinks over a few inches in industrial equipment. More robust than fine-pitched connectors in dirty high-vibration environments. |

@futurebird @fraggle my whole career right now is supporting the development of 2.4GHz wireless communication ICs including BT. Even I'm constantly wondering why people are putting Bluetooth in things that obviously don't need it (I'm looking at you medical devices).
