    Pulsed helium3 fusion in a magnetic bottle, not lasers or same old tokawhatever...

    Wow, those are some crazy devices. I'd never have thought they reach those strengths. The prospect you linked to compares their stuff to 2009 models (feels recent) and it's not even close, 28.2 vs 23.5. It's still quite abstract to me and I'd have trouble appreciating the opportunity this opens...

    Pulsed helium3 fusion in a magnetic bottle, not lasers or same old tokawhatever...

    I'm sorry, I did learn more from your post, it's an eye-opener, but I need to ask. Is that a medical device? Can one get inside that 20T magnet, have you tried to, and what would happen/happened (assuming no metals implanted)?

    Pulsed helium3 fusion in a magnetic bottle, not lasers or same old tokawhatever...

    Oh and in 2021 there was that new superconducting magnet at MIT that obtained 20 Teslas. A MRI machine is like 2 T. I can make like 0.5 T at home, but for just a milisecond :<

    Pulsed helium3 fusion in a magnetic bottle, not lasers or same old tokawhatever...

    I was listening with one ear, but if I understand correctly, the energy is in the form of back-EMF after the squeeze happens. I saw that "bottle" design a while ago either in another project or maybe it was the same one. National Ignition facility had that breakthrough around Christmas...

    Motherboard audio codecs - please recommend

    I was alluding to electrical 'noise' issues that like to rear their head in computer audio, especially when the soundcard lives inside the case. For example, I could hear a faint buzzing noise whenever moving the mouse cursor back when I had a Prodigy 7.1 HiFi soundcard and a specific Gigabyte...

    Samsung S22 vs. Huawei P30 photo shoot-out

    I zoomed in on the close-up powerline pylon and Samsung is basically low-key HDR. I'm not sure what it is we're comparing. They honestly seem to be working very similarly optically. I think it's a matter of coating/filters and digital processing. Who knows what the Samsung one would produce in...

    Motherboard audio codecs - please recommend

    ^ What Sycraft said. I have no idea about the respective codecs' driver quality, which honestly might be the only concern. The Strix one also has integrated Wi-Fi, which, if implemented just badly enough, could actually maybe affect audio. The middle one has also the front panel "proper" DAC...

    Is it possible to (non-permanently) write protect an ATMega32U4?

    I'm a noob and I don't know much, but if the device doesn't need the reset pin for normal operation, you could physically cut the reset pin's connection and/or pull it to Vcc with a resistor. Can't program things without the reset pin. But, I think this is more of a corruption issue and you...

    I microwaved a R9 390X gaming and now my pc won't run after 3rd time

    It's only fitting that a thread about microwaving GPUs also has some detective work leading to "Egyptians having to focus sunlight on metal to cook sausages".

    Arduino people?

    In that case, definitely start off with just placing the sensors in various locations and just observe their ins and outs, like cdabc123 suggested. An ESP32 or ESP8266 is an "arduino with wi-fi", almost a drop-in replacement in many cases. You program it in the Arduino IDE, typically using the...

    Arduino people?

    I think they would work, it's just a TO-92 packaged part, and as long as you prevent the pins from shorting out, it should be okay. Datasheet says they can use parasitic power (no dedicated vcc line) up to 100 deg. C. Another thing I remembered, aside from the temperature and humidity, the...

    Arduino people?

    I've found that a good starting point for any project like this is figuring out the rate at which you need stuff to happen. For example, you don't want to poll sensors too often. This step also helps you avoid using delay(), which is a major source of headaches down the road. The FireTimer...

    Arduino people?

    One way you can make it cost-effective is to not use an Arduino development board for the final product. I'm all gung-ho for the tiny85/84 microcontroller, you can get those for like a dollar. The 85 is a tiny 8-pin IC, you can connect a cheap OLED display for digital readouts (0,96" is like...

    Should you pay considerably more for High end Motherboards

    Always went for the lower-middle-end mobos, regretted it every single time. This time around it's a Gigabyte A520 Aorus Elite that reboots my system in random times when core boost is on and all RAM slots are populated. During my s754 days I went ahead and installed a Q9550 on a P35-S3G, only...

    3'rd largest coin miner declares bankruptsy

    Being able to mine anything at all netting you just $1 daily is $30 monthly, and that's real money, even for me in my 2nd world. When SHTF in February, the USD went from around 4 PLN to as high as 5 PLN in October. That lets me offset costs incurred due to hyperinflation here. I think it might...

    Intel Raptor Lake 13900K Overclocked Past 9 GHz

    Those same people will then proceed to support the crap out of each other when something goes down. Yeah, some opinions I prefer to not voice even here, but it's mostly because I'd have to spend a lot of time backing it up with research. The last time I felt "bullied" on here was years ago, and...

    Intel Raptor Lake 13900K Overclocked Past 9 GHz

    You what? The only reason I'm not doing it is because I don't have a Raptor Lake CPU! Sure, it's not for daily operations, but damn if it's not a bigger number than the last one!

    Access Denied on files download to PC from Google Drive

    I gave this question some time in case someone knows exactly if this is somehow related to Google Drive, but seeing as no one chimed in - looks more like virus-related activity.

    Here's a dumb idea?

    I'll just chime in that with Linux, you can disable the "mitigations" designed to defend against attacks on the CPU's design itself (Spectre and the like). If you want raw performance from the CPU also, and use this mode sparingly, you might get more out of the hardware. I'm not, however, a...

    hey mice people, what's your take on Pointer Instruments $270 mouse?

    hey mice people, what's your take on Pointer Instruments $270 mouse?

    What they call "resting" one's palm, for me might end up causing strain. When you're holding on to something round that has buttons (giggity), your fingertips are already pressing onto the button surface AND your fingers are slightly curled up, which is the natural position. Clicking then...

    How much RAM you got?

    I'm still at 32 GB @ DDR4, but wouldn't mind downloading another 32. The reason was moving to Mint from Win, I'm one of the lucky people who can mostly get by with the ecosystem. The 'memory' widget shows my RAM constantly maxed out, with a VM running for Office 24/7 and other daily things...

    Steam On Linux Usage Climbs Higher Thanks To The Steam Deck

    I currently own one game and that game is Project Zomboid, via Steam. The game itself runs just as well on Mint 21 as it does on Win10, no ifs, no buts. I play windowed on a dual monitor setup, and things like sliding the cursor from the game over to the other screen work perfectly. The Steam...

    Is there any way to control how Linux uses the second monitor?

    Damn, I'm running that distro on an nv card w/ two monitors and cinnamon. It worked for me out of the box so I'll try to help you troubleshoot in around a week (once I get back home from a thing).

    Case connector header, e.g. ASUS - timewasting lunacy in 2022

    I find it annoying in smaller cases, where the mobo edges end up really close to the case bottom. Yeah, I guess it is one of those things they could step up their game, like CMOS reset buttons, little 7-segment displays for error codes and such. Or reversible USB. What you can do is get some...

    ESP32-CAM, the poor man's wireless CCTV

    Bumping this because of great justice on the part of the ESP32-CAM_MJPEG2SD project team. ( https://github.com/s60sc/ESP32-CAM_MJPEG2SD ) Since my initial thread, they really stepped up their game and the software now has stuff like: - downloading avi instead of mjpeg - triggering recording...

    Problem typing with mouse

    A bit later on I remembered something - there are many poorly designed programs that require a lot of input, like in data entry, where you indeed have to constantly be using your mouse to navigate a form (because it doesn't auto-skip fields and does not have hotkeys). Subtitling videos comes...

    Problem typing with mouse

    Normally I try not to knock anyone about how they do stuff as long as it works for them, but I am surprised you're actually managing to use the mouse to precisely place the cursor and maintain typing speed. I wasn't able to cut it. I'm not going to just change your ways, but I will ask - and...

    WTB: raspberry pi 3 or 4

    They've been nearly completely unavailable for nearly a year now. Supposedly, it's the global "shortage", combined with the fact that the RPi foundation "is forced" to deliver units to the big guys first, those who depend on them for their products. Individual end users are way way way back in...

    Intel iGPU Linux users are advised to avoid kernel 5.19.12

    Same with my Mint install. I did like to play with experimental kernel stuff, but this one is nasty. You wouldn't even be able to tell it's running out of spec before it died. I remember trying out Ext4 really early, it accidentally some of my files.

    The crime against humanity that is the modern OS desktop, and how to kill it

    Dual boot - passing files

    You can browse ntfs volumes from any linux distro. Windows needs extra stuff to read ext3/ext4, so a FAT or ntfs voleme on the drive or other drive would do (like Axman said). Theres also the Windows subsystem for Linux, used to be available for 10, but now MS' manual for it lists 11 as a...
