it affects the whole country.

https://downdetector.com/status/verizon/

I got got off the phone with Verizon, and they said the issue started on Aug 28 where some phones got a network update that limits their ability to connect to the towers. He's making a ticket with the network team to bridge from the tower to our iphone to push the network software update.

I guess many phones can't connect to get the update to fix their last bad configuration.

I hope it gets resolved soon.

my iphone 16 pro works, but wife's iphone 14 pro is "sos only" mode.

we tried the full reset (volume up/down/side button hold) and network reset, which is not helping.

Both my and her phone have same cellular data settings.

tried calling '611' verizon help line which dumps us saying "the system is down" unable to take calls.

it's a big outage for sure.

Has anyone used dark color 3D filament printed onto copper clad PCB as photo resist or etch resist?

It might be tricky printing PLA directly to copper clad PCB, but then you could expose the board to UV or etchant to make the PCB traces. Then remove the PLA plastic to expose the copper traces.

I love their pricing options include larger ranges of numbers, and enterprise class also includes negative numbers. ha ha.

Best part is that 'sign up' links to https://archive.org/donate/

I didn't realize this was the same creator of the tiny LED matrix earrings. I love the attention to detail in the work and the article. Super interesting!

It seems like a high-level overview, good for somebody new to the topic.

It also linked to this resource, which was more in depth... https://github.com/mytechnotalent/Reverse-Engineering

EDIT: Whoops... it looks like it mostly links back to the original article.

I would use a variable power supply, amp meter and some sacrificial fuses. Slowly turn up the voltage while watching amps on the circuit until it blows? Or simply apply the rated amps (with current controlled power supply) to verify if/when the fuse blows.

I have a multiple-fuse assortment kit that was a great (too good?) deal from AliExpress. Now I'm thinking I need to do some of those tests myself to verify their rating.

I used Eye-Fi for several years and enjoyed it. There was some opensource software to use it on a private LAN.

Searching 'wifi sdcard' and I found several vendors still making those cards, but I haven't used any of the newer ones.

This is a nice example of using ESP32 and Arduino.

Thanks for sharing the details of your project!

20,000 amps

200,000 electrical contacts

850,000 cores

and that's the "old" one. wow.

I was imagining something like MotionEYE OS https://github.com/motioneye-project/motioneyeos/wiki

Where I would download the sdram binary image and flash with Balena then boot on the Pi.

Great work anyway! It was a nice opportunity to read up on Nim language too.
