  • How to convert USB webcams to HDMI

    There are a handful of interesting USB webcams out there, which naturally work great with a computer. But what if you want to combine video from a USB webcam with your HDMI cameras in a video switcher like the ATEM Mini?

    okay real talk. I have about two point five million USB cables of various types and sizes. I don't want to get rid of them because they're all different and serve different purposes. What's the best way to store these some way that I can find them??

    why yes I did just plug a USB-C hard drive into a USB-A port and was confused why the computer didn't recognize it.

    I blame the fact that I just got off a 14 hour flight.

    I'm glad we've got USB-C now, but seriously someone needs to invent a reversible SD card. I still plug those things in backwards every time.

    Finally figured out how to format a memory stick for optimal compromise between compatibility and file sizes.

    The goal is to be able to stick this memory stick in anything from the last 15 years and be able to load files on and off. The implementation idea was to have two partitions, one FAT32 for compatibility with everything, and one ExFAT for wide compatibility allowing larger files.

    The mistake I made last time was using a GUID-based partition map, which rules out compatibility with older hardware which uses a BIOS. This can be rectified by using the older Master Boot Record partition map, which has some restrictions, but nothing particularly relevant in this case.

    I had no end of problems trying to achieve this with the Gnome Disks tool and GParted, and on Mac OS 10.11 it’s not possible in the Disk Utility GUI. It is, however, very easy using the command line Disk Utility tools.

    Firstly, run

    diskutil list
    

    to find out the descriptor for the device you want to format (e.g. /dev/disk2, referred to in future examples as /dev/diskX), then

    diskutil unmountDisk /dev/diskX
    

    to unmount it in preparating for formatting. I’m formatting a 64GB flash drive with 62.1GB actual capacity into two equal portions, so my command ends up looking like this:

    diskutil partitionDisk /dev/diskX MBR ExFAT NAME_OF_FIRST_PARTITION 31.1g FAT32 NAME_OF_SECOND_PARTITION 0g
    

    where the format is pretty self explanatory:

    volume partition_map partition_1_format partition_1_name partition_1_size partition_2_format partition_2_name partition_2_size
    

    The size of partition two is given as 0g, which results in the rest of the available space being taken.

    A list of available filesystems for formatting can be browsed with:

    diskutil listFilesystems
    

    I just tested the newly formatted universal memory stick with a computer with which it previously didn’t work, and it worked perfectly, so I’m confident that this approach achieves my original goal.
