Looking at a Real Fake Raspberry Pi RP2040 Board

I had a busy week and missed Teacher Tuesday, so let's do Thinking Thursday instead! School is cancelled today due to snow so I watched Veritasium's video on the world's most important machine: youtu.be/MiUHjLxm3V0?... Lots to think about, and great to share with science and technology students.

Also - several new/updated CircuitPython School video lessons related to CircuitPython for the Beginning Electronics Maker. See the start of the playlist at bit.ly/circuitpytho... #CSed

Folks, my mini-IBM PC is finally complete and fully documented! I invite you to take a look at the full tutorial and a section on why and how I designed this build. Please share this news and thanks to all who encouraged me. adafruit-playground.com/u/AnneBarela...

Just reminding everyone who still has an X account of this from Private Eye

Usually, a lack of ideas isn't the problem...

I was interviewed on the Agile Embedded Podcast recently and had an enjoyable chat with hosts Jeff and Luca about using MicroPython professionally: agileembeddedpodcast.com/episodes/mic...

Five Important Hotkeys in KiCAD's PCB Editor!

KiCad beginner tip: In general, schematics should read from left to right, input to output. I/O counts as output for these purposes. Basically, you're mapping out the flow of signals, from the inputs, through the components, on to the outputs.

Intermediate KiCad tip: A little colour-coding using net classes can really make your schematic easier to read. Of course there are those who are colour blind, but at worst this is neutral, since the default has everything blue or green anyway.

KiCAD Tips: Making a Custom Footprint for Reverse Mount LEDs

I wished someone showed me this about I2C before. During any kind of data transfer, the SDA line should never change while the SCL line is high, only when it's low. So, it changing when it's high is a "Start" or "Stop" condition. You do not have to pair "Start" and "Stop"

I have updated my wiki. It's a lot easier to navigate and view especially on mobile. I've also added some new scans. wiki.nataliethenerd.com

This day 57 years ago. Earthrise. A remarkable view of Earth hoving into view as the Apollo 8 command module flew over the lunar surface. That's us. That's home.

Happy holidays! Probably my favorite stop-motion from the past few years. Really enjoyed creating this one.

🎵 I changed 120 light bulbs in a 300 light tree, My fingers are bleeding, branches keep poking my knees, This is just stupid, and they’re still burning hot, Next year I’ll have to give LEDs a shot! 🎄 (As long as I can find some nice ones that are flicker-free!)

You know the tune... 🎵 Last Christmas I gave you new bulbs, Amazon’s Choice, Incandescent… This year, just as I feared, Many were not iridescent!

My last issue of the year is filled with goodness. Back for the January 12th issue.

KiCad 10 is almost here! That means we need to update our demos. This highlight the features and workflows used in real world KiCad projects. Do you have a favorite project? Nominate them here and we'll reach out to see if they'd like to be featured forms.gle/jHcrZhgStHF3...

Great points! 👇

Does anyone following me have an xTool LASER cutter (M1, S1, or P2) and a burning (🔥 😉) desire to build a TARDIS? My LightBurn file works fine on my 20W diode LASER, but I wanna see if I've properly transferred the settings to an xTool XCS file. PM me your email and I'll send it for you to try out.

It's teacher Tuesday!! I used this #tinkercad circuit to teach a grade 9 technology class about how sound is made, as well as to how to create a simple play function using #arduino UNO C code – check it out: www.tinkercad.com/things/lADZL... #STEMeducation #electronics #programming

Let people be their true selves, as they know and understand them. Let children explore their identities. Celebrate difference and variety and the incredible spectrum of humanity. The only alternative denies an opportunity to celebrate the joy of human flourishing and is ultimately unspeakably cruel

I understand that a lot of folks have been misled by fear-mongering and powerful regressive voices but it’s still astonishing to me that so many have fallen for the idea that oppressively policing other people’s gender identity and expression could in any way be part of an enlightened future.

It's still a bit of a mess internally (this is my first full prototype). I have changed the board shape since this edition, changed the battery and speaker.
