Hey Mycroft AI, are you aware of the backend issue preventing anyone from pairing new devices? community.mycroft.ai/t/cannot-regis… A bunch of us new users are eager to get started, but stuck! 😟

This is what you get to do after you forget to put I2C pull-ups in the prototype design. At least it was a relatively simple fix though!

I just finished successful setup and calibration of my shiny new Snapmaker J1 IDEX printer. To celebrate, I told it to print the built-in 2-color shark. Now I am VERY CONFUSED. 😂

I've been working on this project for a while, and it's just starting to get a teensy bit of air under its wings. If you have any interest in personal data organization, check out the quoted link, as well as tidybytes.com/tyd for a video by yours truly! 🚀

I decided to implement Chutes and Ladders in Python, which took all of 10 minutes while my kids played it at the kitchen table. Interesting: the average number of spins to win always settles at 39 after a few thousand runs.

I’ve ordered Digi-reels from DigiKey lots of times, but this is the first time I’ve seen this. I didn’t even notice until after I’d loaded it into my PnP machine (which uses simple feeder arrays, or I would have noticed sooner). Do you see it? HINT: this picture is not mirrored.

Ever had one of those troubleshooting facepalm moments where you finally figure out the problem and then giggle at the absurdly stupid and obvious fix? If you have 12 peripherals on one SPI bus, make sure you properly configure all CS pins *before* you try to communicate. 🤦🏻‍♂️

Once again, I see why the Saleae Logic is my absolute favorite bench tool. Writing a high-level protocol analyzer in Python to decode MicrochipTechnologyInc. MCP251836 CAN controller+transceiver SPI transactions is about as painless as it could possibly be.

I have this extremely specialized custom 3-axis rotation platform full of Actobotics® parts, stepper motors, 6-wire slip rings, etc. I don’t need it anymore, but trashing it feels shameful. Anyone here have some project that could make good use of it?

PCB engineers: I have a Black & Decker TO1750SB toaster halfway modded to an IR reflow oven. (It works, but I needed more internal volume.) I’d rather send it to someone than throw it out. Anyone interested for the cost of shipping? Relays+controller+thermocouple not included.

What do you get when you mount a Promethean ActivPanel to a FlexiSpot standing desk frame and drive it with a little Beelink N150 mini PC running Linux? The world’s biggest open-source 4K touch table! The possibilities are endless!

Been a long time since I did a Blinky project on a new platform. I’ve never played with STMicroelectronics STM32 before, so I thought it was time to broaden my horizons. Super easy to jump in with the Nucleo G0B1RE using PlatformIO on Linux. Even got OpenOCD debugging going!
