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.
Thur 8/29 Stream: Attempting to program this (hopefully) clever clock delay circuit. It'll be used in my state mode logic analyzer project. Twitch or:

🌦️Data from the garden, thanks to Bald SENSE and MacroFab's turnkey PCB assembly platform. Dive into my latest video to see DIY vs. Turnkey and my turn-on process.

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

Brand new Arduino-Pico version just dropped, with support for the RP2350!
https://github.com/earlephilhower/arduino-pico/releases/tag/4.0.0
Thur 8/22 Stream: Let's do some RP2350 design. I want to upgrade my state-mode logic analyzer. Come say hi.
EDrTech's PMG001 module unlocks precise power control and monitoring for battery-powered devices.

I definitely feet the mental stress when I realize I could have accomplished more.

Pico 2 pinout now documents HSTX pins and - thanks to cfp of PicoScratch - documents the test points - https://pico2.pinout.xyz

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.”
Questions frequently asked by the utterly deranged. https://www.friend.com/product.html
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.
Thur 7/25 Livestream: Soldering some Banana Plug Adapters for power supplies. Adapt USB, JST PH, Barrel Jack, and Screw Terminals to test equipment. Come say Hi! https://youtube.com/live/DKOYQZEC8t4
Fun fact: the PicoScope 2000A was one of my first live streams (many years ago!) Here, I checked out PicoScope 7 because I needed an I3C decoder.
