Anyone have details about this NTE Announcement (LinkedIn)? Who bought them in 2022? Looks like all stock is cleared out of the channels and their site is down. Seems like an abrupt end. :(

(Sorry for the weird looking URL, blame LinkedIn.)

Well. I should have listened to chat. The correct answer was to just do it in the RP2040's PIO. 18 lines of code and two cups of coffee later ...

C-side keeps increasing the delay between Clock "In" and Clock "Out"

Since #ParamountPlus makes it impossible to get a screenshot, I went ahead and mocked this up in honor of Gabriel Bell. #startrek #ds9 #bellriots

Here's looking forward to a day when the United States finally faces its ongoing humanitarian crises.

As Raspberry Pi 5 broke pigpio, I implemented bit-banged UART RX in Python using gpiod:

My application runs at very pedestrian speeds (4800bps), but I'm still shocked this works reliably, even when the Pi is under load. Haven't tried faster speeds yet. #RaspberryPi

A resistor was also trying to make a run for it, but came to its senses.

a (human) friend texted me this link with the question “is this real?” and maybe I’ve been in the mountains for too long but it can’t possibly be real, right? Like as a critique or a satire it’s both incisive and clever, but as an earnest attempt at a product it’s just… deeply unhinged?

“When will I receive my friend?”
“Pre-orders will start shipping Q1 2025.”

Yellow: Temperature (digital sensor)
Green: Battery Voltage (in ADC) Steps
Blue: Open Voltage Divider (in ADC) Steps

FeatherS3 (ESP32) with custom sensor Wing in a box, in my garden

As the temperature peaks, looks like the ADC (or its ref) is drifting.

Data is cool

I don't normally write or promote Kickstarter projects. However, since this is Particle and they have a proven track record of using crowdfunding successfully, I am comfortable sharing this one.

**Also**, I want one. It's like a mid-range smartphone on a Pi board for $149.
