    SkyHound0202 got a reaction from Electronics Wizardy in How to simply store this energy?   
    Replace the capacitor with a rectifier and battery combo. The rectifier to ensure you always convert AC to DC, regardless of the direction. The battery can then be charged by the DC output from rectifier. Use a nickel–metal hydride battery. It is safer and more resilient to intermittent charging.
    For output, add a current-liming resistor and/or follow this page for a more reliable design.

    DVI-A: analog only (VGA backward compatible)
    DVI-D: digital only
    DVI-I: digital and analog (VGA backward compatible)
    No, DVI-D does not support converting to VGA with a passive adapter. An active adapter must be use in that case.
     
    Actually for your GPU, it only has HDMI, DP and DVI-D. Thus you can only use an HDMI to VGA or DP to VGA adapters, or an active DVI-D to VGA adapter.

    Did you configure the boot order or boot mode (UEFI or Legacy) correctly?
    It should be the same as the previous computer, otherwise it won't boot.

    Ryzen 7 1700 will work out-of-the-box with B450 AORUS Pro.
    The memory kit will work, but given that the IMC on 1st gen Ryzen has difficulty hitting high memory frequency beyond 2666 MHz, I doubt it will operate at the rated 3200 MHz.

    SkyHound0202 got a reaction from Giganizer300PRO in Old SATA 2 drives for RAID - is there a point?   
    Pay attention to Host Bus Adapter (HBA) card and RAID controller card. Both looks similar, yet only the latter has RAID function. (more on that later)
    Depending on vendor and OEM, the driver and documentation support might vary. Broadcom (LSI) has archived drives and firmware for years, some others may not even bother to update manual.
    You might want to pick up a RAID card with battery if you prefer data integrity.
    SFF-8087 (Mini SAS) and SFF-8643 (Mini SAS HD) are different connector types of the same protocol. Both can be connected to 4 SATA drives.
    Yes. If you want to plug most your drives in and build a simple RAID without using on-board Intel chipset, then buying a dedicated RAID card is an option.
    Or, you can get a cheap PCIe to SATA card (those ASMedia HBA cards) and plug your existing drives onto it and use the 6 native SATA ports from Z97 chipset for RAID (albeit only making a 6 disk array).
    LSI SAS 9210-8i is an HBA, not a RAID card. Nevertheless it can be flashed to IT mode to function as an HBA for use in unRAID.
    (Speaking of unRAID: it's different from the standard RAID levels and accept cheap HBA cards, but comes at an additional license cost. Linus uses it very often, but this might not apply to everyone.)
    This is a PCI-X card. It's physically incompatible with your system.

    SkyHound0202 got a reaction from YellowJersey in 360° or 180° video camera for sports   
    Here's a comparison of the 360 degree cameras.
    Yes. It's indeed possible to sync up fisheye footage and stitch them into sphere, but I fear that GoPro will not provide enough Field of View coverage to form a good 360 video, unless using multiple camera.
    Honestly, if you want to stand out when covering high speed sports, you can:
    1) shoot those gorgeous cinematic slow motion shots with a high speed camera (or phone with lens adapter)
    2) from a different perspective with a crane or a drone (please refer to local regulations), or a head mount camera on contestant.

    SkyHound0202 got a reaction from MrJoosh in Old SATA 2 drives for RAID - is there a point?   
    Yes. The speed of the RAID 0 array increase near-linearly when the drive number increases, as Tom's Hardware demonstrated.

    Your analogy is correct.
    Expected roughly 10% percent drop off due to controller latency and overhead.
    You will need an 8-port hardware RAID Controller Card if you want to plug most of the drives into the system in RAID configuration. (I recommend a second hand MegaRAID one with some SFF8643 to SATA cables. More on that later.)
    No, this will not work. As Intel RAID requires the drive to be connected directly into the chipset, i.e., the 6 port on your motherboard, rather than any third party adapter card(s).
    If you want to use a RAID card, it's better to connect it to a native PCIe slot that connects to CPU instead of the chipset to avoid DMI link bottle-necking the throughput (that should be PCI_E2, PCI_E5 or PCI_E7 for your board, depending on your exact configuration. Consult you manual.)
    You will also need some knowledge of Option ROM operation or command line operation. (MegaRAID card has a GUI MegaRAID storage manager, which may be easier for you)
    Also check if your power supply is sufficient to power all the drives and if your case will ever fit all of them.
    Use 8 drives with an 8-port RAID card, save 3 drives of the same model. In case of drive failure, just swap another one in.
     
    As this is more of a hobby project, it's fitting for you to get some cheap stuff to work with. I estimate it will cost you less than 35 EUR (5 EUR for 2 SFF8643 to SATA cable, 30 EUR for an OEM/used MegaRAID card, there could be better deals) for the whole setup.

    SkyHound0202 got a reaction from Sebastian Kurpiel in Shooting in the snow   
    DSLR should be fine in winter. You can leave them outside for a while till it reach ambient before using it.
    Some component will be affected by the cold. Screen will be less responsive and battery will discharge faster. Use viewfinder and bring more spare battery.
    Get a pair of gloves that is easy for you to operate the camera while also protect you from the cold.
    Snow is highly reflective. Configure white balance and exposure to compensate for that.
    When done shooting, put the camera in a dry chamber or plastic bag to slowly warm up to room temperature. There will be a few droplets but they will evaporate eventually.
    One last off topic thing, a DSLR on a snowboarding trip? Shouldn't that be suiting case for an action camera, like a GoPro?

    There's no point getting the AirPods if you are on Android. It will work, but just not as good as using it on native iOS devices.
    Also, being an Android user also gives you more choices, not just IconX.
    Other choices includes (but not limit to): Jaybird Run, Bose SoundSport Free, Bragi Dash, Jabra Elite Sport, Erato Apollo 7, Yevo 1, etc.
