I try really hard not to have conspiracy brain. But I can’t help but think Walmart knows the source (or at least has a good idea) of the Cyclospora outbreak. They have gobs of data about who bought what food and then later bought items to deal with the diarrhea.
The GOP Platform: Protect the fetus; starve the child. Honor the soldier; abandon the veteran. Enrich the corporation; fleece the worker. Quote the Bible; ignore the verses.
I often say that the fight for democracy is the fight of our generation. But let me be clear, if you aren’t fighting for Black voting rights right now then you aren’t really fighting for democracy.
I'm starting to think the MAHA/Wellness mindset is just lazy doctoring. A good doctor works with you to treat/solve what is ailing you. Wellness is about what you're doing (or not - blame). While that can help, it's not going to work for everything. And in some cases can be outright deadly.
Happy 50th Apple! I grew up with an Apple //c, then one of the cool transparent Macs, then one of the first Powerbooks in college. We now have M1 and M4s. Every one has just been a solid, dependable computer. #retrocomputing I still have the //c. If you have one and want to restore it... 1/2
Hi! I'm looking for broken Apple II keyboards. I successfully designed a replacement keyboard for the Apple IIc, and I'd like to do the same for other vintage computers. Is anyone willing to let me "rent" a keyboard so I can get measurements? I'd happily send $$ or a prototype replacement.
I'm determined to figure out how to do a 4-wire XY capacitive sensing trackpad. This is attempt 3.
Happy Pi day & Happy 5th Birthday to Piper Make! @playpiper.bsky.social We're still going strong and it's still one of my favorite tools to use personally. I believe deeply in the mission of our company - to bring fun, quality STEM/STEAM education to kids through stories and exploration.
I'm selling this breakout board $5.50 right now: www.tindie.com/products/mat... I've got a new version in the works, but I need to sell of the small amount of stock I have left of the current version. If you've never played with the CH559 MCU before, it's kind of fun ;) 1/2

Most people study what misinformation says. We decided to study how it looks. Using novel multi-modal AI methods, we study 17,848 posts by top climate denial accounts - and uncovered a new front in the misinformation war. Here's what it means 🧵 www.tandfonline.com/doi/full/10....
Everyone needs to understand what Elon and DOGE are building, an AI driven panopticon that will know everything about you and will be used to ensure compliance with their fascist agenda. They are creating a unified database of everything the federal government has on every single American. 🧵1/
It's up for sale! Grab yours today! The ATTINY PRO is a small-but-capable ATtiny3217 development board with a form-factor similar to a Pro Micro. It's like the original Arduino board, but with the much better peripherals of the Tiny AVR 1 and 2 series. www.tindie.com/products/mat...
The Raspberry Pi Pico came out just over 4 yrs ago. At the time, we had shelved a project we were building - it was good but we didn't love the boards we were using. When the Pico came out, we brought the project back & worked fast to finish it. Happy Pi Day / 4th Birthday make.playpiper.com !

Hi Electronics Bluesky! I made a new module for my Tindie store (and honestly, for me to use too!) It's a dev board based on the ATTINY 3217. It has an onboard CH340 for both programming via UPDI and for UART<>USB. I love these chips as I2C peripherals. Tindie.com/matzelectronics
I talk about race, openly and honestly. It's also what I do for a living, and while it can be uncomfortable for white bodied people to hear criticism aimed at white folks. If we are to move together as a society, it requires getting real and moving past the fragility.
I generally love following you and getting your knowledge and energy. But "white people this, white people that," comments are a step down. I'm not saying it is reverse racism or anything like that, but it is a broad and weak generalization. It's like me saying all Trumpers are stupid rednecks.
New Tindie.com/stores/matzelectronics products in development! These are all capacitive-touch PCBs. Left one is a track pad, middle is a keypad, and right is an iPod-style rotary wheel.
DOH! Forgot to check the box to remove the order number. Ugh.
Trying to design an input stage for an ESP-32 based scope. Haven't had to bust out my own scope in a while. It amazes me how quickly this analog stuff can get complicated! Just trying to attenuate and bias a range from +/- 5V to 0 to 3.3v, and I'm 4 op-amps deep.
I made a new thing! Here's a four digit 7-segment display module. It's nice and bright, and it's designed to be connected via I2C (STEMMA QT, QWIIC). Firmware is open source and written in Arduino so it's easy to modify to fit your needs. Available here: www.tindie.com/products/mat...

Trying out my not-yet-finished mechanical keyboard this evening. It's my first mechanical keeb...it's going to take some getting used to, but I think I'll like it! Not sold on using CircuitPython yet. A couple of weird issues that I have had to work around. I think I eventually land on Arduino.
