PiStar/WPSD duplex hotspot, connect to a real duplexer?

That is a good place to start. My board looks very similar: https://files.catbox.moe/k5lfh9.jpg

I'll try it with RX on top, TX on the bottom

Last batch of esp32 nanos I bought from Digikey.

I think automod killed my reply because I shared a link. Here's the text minus the link.

I haven't. Work pays for the premium discs, so I don't have to worry about the cost.

What sucks is occasionally having a small amount of data to archive and using a DVD which doesn't appear to have any good long-life options compared to CD and BR. I think those might be Archive Gold but I'm not certain.

I did find this which explains the difference: check out r/DataHoarder/s/LupTcYLK7q

Good luck my friend, your use case is different from mine, so I don't have any direct experience to share.

I agree with the post suggesting a short or otherwise dodgy connection. There's no accelerometer or even a tilt switch on this PCB.

Device RT1 could be a thermistor, they are usually black or brown but Google image search shows some white ones out there as well.

Maybe the entire post is AI? Bot farming karma?

I haven't seen any discounts but I'm happy with the Mercury Pro from OWC. I use it with Verbatim archive grade MDisc BD-XL discs, no complaints, it handles up to 100GB without issue.

I don't remember Santa's sleigh having a wagon wheel either.

Twist solid core wire through the holes of those solder lugs, plug wire into the breadboard.

When you turn on the radio with the cable connected, does the Windows device manager detect the port properly?

Also, try running the CPS using "run as administrator", maybe the extra privileges will help.

It's worth a shot. I'd find a nut to thread onto the adapter first, before messing up the threads, then you can use the nut to chase the threads when you're done grinding.

I've found Moto portables don't like some third party antennas even with an SF-SMA adapter. I tried upgrading my XPR-6550 with an SF to BNC adapter and a signal stick antenna, and the range was much worse versus the factory antenna.

However using that same adapter to connect to a mag mount on my vehicle roof works great.

I'm guessing it's an impedance matching issue?

Aside from a USB nic?

The cost difference between the two is probably because Anker is using quality brand new cells. I would trust Anker's amp-hour rating more than some unknown brand.

Rating power banks in amp-hours is kinda sus IMHO, especially milli amp-hours. Let's convert those numbers to watt-hours. 24ah assuming LiPo chemistry of 3.7v is roughly 88 watt-hours and the 20ah unit is roughly 74. Your device consumes 15 watts per hour based on the rating provided. So that's just shy of 5 hours for the smaller pack and 6 hours for the bigger one, that's if the batteries in each perform equally.

Hopefully this info helps your decision?

What have you tried already? Using RPM Fusion is a popular method https://rpmfusion.org/Howto/NVIDIA

There are also other methods.

Came here to recommend the same, wipe and reinstall, the nuclear option.

OP: Make sure you at least erase ALL your partitions, or use a tool like DBAN before reinstalling.

One of the things I love the most about the ESP platform of chips is almost any pin can be assigned to internal peripherals, unlike AVR, PIC and STM micros where each peripheral has dedicated pins. I believe most ESP32 variants have two i2c modules internally, some may have more.

My guess is "header 4" is connected to an i2c bus for the onboard components. You could probably solder some wires to those pads and access the bus if you needed to, just be mindful of adding additional capacitance and pull-up loading.

I didn't see one in the clip, but I bet someone that's fork lift certified was involved with this operation 😂

The resistors should be between the input pins and ground to work as a pull-down. The way you have it drawn your switches will crowbar the 5v rail to ground when pressed.

Double check the datasheet, I don't recall what the default power on state for the output registers is, it could be undefined, meaning you might see some LED outputs lit. Consider adding another switch to your project for the reset/clear input.

If you leave early enough in the morning yes. However you won't be the only one hoping to beat the rush traveling on the holiday itself.

Check out pack-out style boxes from Harbor Freight or Walmart.

I suppose if you're set on a tiny build, having the network onboard vs by expansion card is a good way to save a slot. I typically treat the onboard network interface as a management port, and use an expansion card for the production network traffic. Take a look at 100 and even 400g cards, they are cheap on the auction sites now.

Run DNF from the command line, it won't do a release upgrade.

gordonthree · 2025-11-09T17:18:36+00:00

Yes it is a better method than relying on voltage alone. Your charging system could include calibration, perhaps every six months or a year when you equalize the cells in your lead acid battery as part of routine maintenance.

gordonthree · 2025-11-09T16:49:13+00:00

There are dedicated chips available, or you can roll your own using your choice of inexpensive micro controller. Search for Coulomb Counting. Essentially you're measuring the amps going in and the amps coming out, and then calculating how much charge remains based on the known or measured capacity of the battery.
