@tubetime Oh no! The bits might leak out! To be safe, don't tilt the board on its side.

@adistuder Related, TestEquity (a T&M rental house) signed them in September 2022.
I don't think there is a direct connection. But I find it interesting that announcement is missing from the news posts before going quiet.
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.
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:

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.

@gsuberland Polymers do not have an electrolyte. The polymer replaced it.
PEDOT is typically used. It oxidizes at high temperatures (which increases its ESR.)
While PEDOT caps have a wear-out mechanism, they differ from traditional wet electrolyte-based caps.
