It appears #microsoft has removed dashed lines from #paint but added the ability to "Create stunning images with just a few few words." I am a huge fan of #ai, but I want to be able to create dashed lines too.

#altium365 is experiencing degraded performance. I cannot download parts from the Manufacturer Part Search panel. 😠
I wonder if this is related to today's issues with #aws.

The Art of #electronics' table of #thermometry methods includes your finger and crickets. 😁
Tabl 9.x.5 from the book The Art of Electronics. It shows thermometry methods, such as RTD and Thermistor, but also some humorous ones like your finger and crickets.

I'm a fan of #chatgpt, but sometimes it's like an annoying person who makes things up and flatters you when they don't know something.

"Good eye" = "You caught me making stuff up."
It provides the examples: “For example, R_T = 100 kΩ sets the switching frequency to 1 MHz, while R_T = 200 kΩ sets it to 500 kHz.” cgervasi: I do not see the example of R[T] = 100k --> 1MHz and R[T] = 200k --> 500kHz in the datasheet. ChatGPT: You're exactly right again — and good eye.

I feel like I'm watching Mariner and Tendi at #stlv. The voice actors have the same personalities as the characters.

#tariffs on #pcbs change like the weather. My understanding is it's because the law allows the president to single-handed impose these #taxes in an emergency. There's no standard, so the president really wanting it counts as an "emergency". We need reforms so one person cannot raise taxes on a whim!

I know nothing about #birds or #birding, but I saw this #bird in downtown #madison, #wisconsin today with blue coloring on the sides of its head. I wonder what that's about.

I am SO impressed by how today's #nokings demonstration in #madisonwi was organized. There was puppetry, fun things for kids of all ages, and brief big-tent speeches about the importance of standing up to authoritarianism.

These #perkinelmer ACULED VHL (Very High Lumen) LED modules have a different pinout for IR vs visible. I think their 730nm LED module follows the IR pinout, even though it's red, not quite IR.

I figured this out the morning after ordering boards from #sunstone […]

In this picture from the NYT, Rubio looks like someone thinking hard about his life choices.

The text says #kamalaharris is not going to send an endless number of text messages. It makes me think it's not really her campaign. 😆
Text screenshot: Kamala Harris here. I'm not going to send an endless number of text messages, but this one is important. You deserve to know why. In two days, the DNC closes the books on a very important FEC fundraising deadline. When it ends, they are legally required to report what they've raised and how many donations they've received will eventually be public as well.
