I got a slightly less silly solution. If I'm not mistaken there are 4 RAM chips on the board. If any of the preorder boards have one or two defective memory chips those could put aside and shipped as 3 or 2 GB devices with the defective chips disabled in the firmware. Hopefully none of the...

Awesome. This. New diseases evolve. They always do. That's life. No government can insure 0 people will die from a new disease. If that's the yardstick someone is running on, it's lunacy. Practically nobody, as individuals with personal agency, even had stocked up $40 worth of supplies...

Since the topic is getting derailed let's do it constructively. Help researchers find ways to attack COVID-19 If you think the government isn't doing enough do more: Folding@Home: https://foldingathome.org/ https://foldingathome.org/covid19/ Rosetta@Home: https://boinc.bakerlab.org/ Throw...

History will judge it's been handled amazingly well. The best any pandemic has ever had in the entire history of humankind. You want history? https://en.wikipedia.org/wiki/List_of_epidemics https://en.wikipedia.org/wiki/Black_Death "The Black Death, also known as the Pestilence and the...

For a phone-capable handheld switching dynamically between BT headset, speakers and analog headphones is gonna be pretty important. Same for the audio input. I already use that feature every day on both my desktop and GPD Win. On the GPD Win when I turn on my BT headset it automatically...

Don't do 44.1Khz to 96K in the hardware driver. At most support 8K, 12K, 16K, 24K, 32K, 48K, and 96K then let the software/userspace handle the other conversions itself. No point in having software that can output 48Khz just fine be tricked into using 44.1Khz only to have the driver resample...

I know It's not a solution for mass-production but I've been toying with glow-in-the-dark filament. It works pretty well with LEDs to charge it. it's a fun effect. I might just DIY customise mine :D Shouldn't be too difficult to design a printable clip-on piece once I get my Pyra.

Nothing a bit of hot glue can't fix.

Those are pretty large but they can be made very tiny. Of course the amount of air moved is reduced too. They work similarly to insect wings and insects can get pretty small. The large ones seem to be running around 50-60hz oscillation which is great for running right off the mains. But like...

While we're straying into the realm of silly humorous cooling solutions... There are tiny piezo fans that could even work at ultrasonic speeds at really tiny scales. And fingers might get numb very quickly due to the imperceptible vibration. But it's something that'd fit in that tiny space :D...

If the tape contacts both the USB shield and the heatsink nothing prevents adding an exterior "USB" radiator. Just a dummy copper plug (that doesn't short out the USB 5V) with fins. Could even make a larger version that powers a tiny fan from the USB port but I doubt it'd be necessary. Want...

While waiting for the pyra I saw some people here had Arduboys so here's something I made for it: Link to my blog entry for the release: https://rv6502.ca/post/2019/01/02/starduino-for-arduboy-3d-gaming-inside-28kb/ The arduboy file...

What they tend to do is a bit sneaky: they give the total mAh capacity from maximum charge to maximum discharge. But give the capacity degradation numbers over the years according to a partial charge/discharge cycle. Say: only charge to 80% only discharge to 60% "2% loss after 5 year." Both...

Normally the DLL (Delay-Locked Loop) should only be disabled to run RAM at very low clock speeds (for power saving). Disabling the dynamic DDR RAM clock speed might also fix the issue. That would explain why the RAM crashes when the device is idle and the RAM controller drops the memory clock...

This is on my GPD Win on XFCE (Xubuntu) with only KDevelop4, g++, and Chromium browser with 3 tabs on gamedev.stackexchange (not a heavy site, it's Q&A text for game dev). Not even inkscape nor gimp opened yet, no music playing. So 2GB might be enough for regular use, a bit tight for developing.

Regarding the 4GB vs 2GB and battery life. Depending on the storage device you use, having the extra 2GB act as cache (Linux does this automatically) can help reduce power usage by having the storage devices stay inactive and the CPU can return data immediately rather than run all the code...

There's two benefits to higher-than-sustainable-cpu-clocks: better performance and better battery life. A lot of games still benefit from having the CPU burst through its AI and render code and then go idle as quickly as possible so the GPU can start its own work as soon as possible. ARM does...

Connecting the heat spreader to the USB ground shields and/or HDMI shield would allow someone to connect a removable external radiator, even one with a small fan powered by the USB itself. Slap an ATmega32U4 on there with a small power transistor and you got a removable USB-controlled-fan...

Yeah, but just replacing just that one wouldn't bring a big failure rate. Also, if it's in fact a ceramic capacitor acting like a piezo buzzer then this would put a good amount of stress on the solder points/traces with the vibration and could snap off the board before another type of capacitor...

Definitely. Ceramic capacitors are essentially ceramic piezoelectric buzzers. Or conversely, ceramic piezoelectric buzzers are essentially ceramic capacitors. Rather than search for it can you "easily" (without reworking the board) temporarily tack-on a larger non-ceramic capacitor in...
