This is for strictly mildly interesting material. If it's too interesting, it doesn't belong. If it's not interesting, it doesn't belong.

This is obviously an objective criteria, so the mods are always right. Or maybe mildly right? Ahh.. what do we know?

Just post some stuff and don't spam.

I used the WiFi antenna of a laptop to wirelessly install ESPHome on an ESP32 (lemmy.world)

Real question, not snark...why did you do this?

I don't have a WiFi antenna, except the ones in my computers. Buying a WiFi antenna online would've taken 2-3 weeks, and I wanted to quickly test how it worked.

Was there no jumper on board to switch the external antenna to the built in one? Many boards just have a 0 ohm resistor that you can add or remove to change the antenna.

This model doesn't have an onboard antenna afaik

Neat! My only criticism is that I find this a lot more than mildly interesting lol
