What could I be testing?

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"

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:

Thur 8/22 Stream: Let's do some RP2350 design. I want to upgrade my state-mode logic analyzer. Come say hi.

Thur 8/1 Livestream: Let's fix some mistakes I made on an oscilloscope active probe text fixture: https://www.twitch.tv/baldengineer/

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.

Success!

In a closing session of #Teardown2024, @benhenchke@leds.social walks through the experience of switching to KiCad (for good.)

Welcome to the right side Ben!

HealthyPi Move is an (open source) wearable patient monitor from ProtoCentral. Here, Ashwin Whitchurch explains the sensors at #teardown2024. Available for pre-order: https://www.crowdsupply.com/protocentral/healthypi-move

Psychogenic explains how to use Tiny Tapeout to configure the magic sand inside of ICs to make your own chips

Day 3 of #Teardown2024 kicks off with Joe Grand talking about and demonstrating fault injection—knowing when to inject the fault is the bulk of the work.
