@hn50 Microsoft also said they couldn’t give employees raises this year.

@LisaSpartan @heidilifeldman @CosmicTraveler Maybe that would be an acceptable outcome.

@mjg59 It’s similar to how 6-year-olds play soccer.

@hyde There’s a reason it’s only opened a sealed cleanroom. 😷

@freemo @kilroy_was_here Any RFI effects in the house? I have a similar rooftop in SF with an EFHW and working on some suspected common mode issues.

@freemo @kilroy_was_here I was thinking the radials might have that effect. Might give a vertical a try one of these days up there. I’ve found 40m CW or FT8 to be particularly triggering. Last night it rang my doorbell system. 😬

@freemo @kilroy_was_here Higher duty modes seem to make things pop on a lot more. But it could be just where that is in the band, I agree.

@mjg59 But does it invalidate all current access tokens? 🤓

@mttaggart I often think of Carlin’s bit regarding education. “Obedient workers!”

A little #ESP8266 project for the week: My cat keeps jumping on the countertops in the kitchen. So here's the quick & dirty prototype: a PIR (motion) sensor, passive buzzer, and button for arming and disarming.The buzzer is configured to play a 1-second warbling high pitched (> 8-12 kHz) tone... enough to get kitty's attention.#arduino #nodemcu

It seems to have served as a pretty good deterrent just from the memory; she hasn't tried to jump onto this counter since. So I've placed it on the further counter to defend. However, I have to remember to "arm" the device, which is easy to forget.I could program a little web server into this, or, I can convert it to #ESPHome and it shows up natively in #HomeAssistant. Easy!

Here are both he #arduino C++ code, and the ESPHome YAML source files: https://gist.github.com/ChrisRomp/3a1342e580dc5c56c6c0b315b85ec2b7Next up, I'm working on a 3D printed enclosure for it in OpenSCAD.
