n00b question, sorry. If I had a desktop that could hold 4 HD and 2 SSD, could I turn it into a NAS? Could someone point me in the right direction if this makes sense?
Power consumption is the main issue. If it’s an old, power hungry desktop and you live somewhere with expensive electricity, it can be quite costly to run. If you have an energy efficient desktop or have cheap power then it will be fine. Just make sure it has a good quality power supply if it’s going to run 24/7.
I recently was gifted a raspberry pi 5 and was looking at domains to buy to host my own instance. What happens to my instance if the domain expires?...
Working on a joystick. Seems like any protocol I use to read from peripherals is going to be bottlenecked by having just one input. My microcontroller might have multiple ADCs, but there’s just one processor stepping through them. Same for spi, or i2c, or uart. There’s really only ever one sensor reporting back its data at a...
Only having one ADC can be an issue when you need readings to be in phase, but for reading any sort of human interface device it doesn’t matter at all. Just cycle through your inputs one at a time. Some microcontrollers even have hardware to scan through multiple inputs automatically. You can use DMA to read the ADC and send data out over whatever communication peripherals your microcontroller has without using much CPU time.
If you are using USB HID, you are limited to a 1000 Hz update rate and that’s really overkill already. You can have up to 8 analog axis in a USB HID game controller plus lots of buttons.
Hello altogether, I guess everybody has some USB-C cables lying around, but wonder if it’s 3A, 5A, 3.0, TB… Anybody able to recomment a device able to determine that? Maybe also something that can be combined with a load tester.
There are simple testers like this. It’s rather overpriced for what it is, but it would be trivial to make one yourself. That will only do a continuity check though. If you want to know what the current or speed ratings are, you will need to read the chip in the cable.
A dedicated GPU will mean reduced battery life. If you are only going to edit video at your desk, I would suggest getting a laptop with a thunderbolt 3 or USB 4 port and an external GPU. Make sure the port provides 4 PCIe lanes, not all of them do.
Ubuntu is already immune to the 2038 bug. The Linux kernel even supports using a 64 bit time_t on 32 bit systems now. Of course some poorly written software could still be affected, but that’s not the fault of the kernel or operating system.
The 2038 bug will certainly cause problems in some embedded systems that still use a 32 bit time_t if they are still running by then.
I got an external hard drive enclosure for the purpose of recovering some of the files from my old laptops hard drive. The hard drive and all of it’s partitions show up in both disks and gparted but it wont mount. When I tried to mount it manually, it gave the error message stating that it can’t read the superblock. I’ve...
The hard drive should be connected by SATA or eSATA when making the image. Connecting over USB is just asking for more trouble when the drive is not working correctly.
I have been distro hopping for about 2 weeks now, there’s always something that doesn’t work.

Since MOSFETs have a gate capacitance you’d want to limit the inrush of current from the output of a microcontroller to prevent it from getting damaged prematurely. That’s what gate resistors are usually good for....
For something that’s not switching at a high frequency, slow rise and fall times are fine as long as you are staying within the safe operating area of your MOSFET. A 10K gate resistor could certainly work, but it will depend on your MOSFET and load.
I still get over 12 hours of web browsing or video playback with the backlight around 30% on mine even though my internal battery is down to 60% capacity and my external is around 90%. Standby drains about 10% overnight. I am running Linux Mint on mine and I set up TLP. Undervolting can increase the runtime quite a bit, but I haven’t bothered with that yet.
The T480 and T580 are some of the last ones they made with swapable batteries. Everything works out of the box in Linux except the fingerprint scanner which needs some additional configuration.
I have a T480 with an integrated GPU and the largest battery. It runs for a long time on a charge and there are lots of spare parts available.
I’ve gotten both of my thinkpads used, so none of that money went to Lenovo or Microsoft. The laptops that come with Linux are expensive and are rarely available used.
I’ve been on Reddit for over a decade. But I’m done with that site and want to do something else. What do normal people look at on their phones? Is it all social media? Streaming?
My phone has an FM tuner, so I usually listen to local radio stations. Sometimes I watch TV shows or movies I downloaded on the SD card, but I prefer watching videos on a larger screen when possible. Cell service is crap around here, so streaming is not very practical.

That is strange that they would have size limit for the SSD. Maybe it only supports single sided M.2 drives, but if that’s the case, they should have just said it.
Timeshift works best if you use BTRFS for your root partition because snapshots can be taken instantly. I have mine setup to automatically take a snapshot every day.
It could be resized too. 5120x1440 is way too big for a website banner. There’s no reason to go more than double the size it will actually be displayed at. That would bring it down to a couple hundred KB.
I got these TP4056 modules from an AliExpress vendor and fail to understand how the protection circuit works or if it’s just typical Ali shovelware. It could be my limited understanding of electronics....
The drains in the 8205 MOSFET are connected together internally. In a DW01 circuit, they are not connected to anything else.
One MOSFET stops the battery from charging and the other stops it from discharging.
The MOSFETs are in series, but in opposite polarities. Two MOSFETs are needed to block current in both directions.
The DW01 uses the voltage drop across the MOSFETS to measure the current. The overcurrent threshold voltage is fixed at 150mV. Using a larger MOSFET that has a lower RDS(on) will increase the current limit.
