John calls in to talk about how you can get a USB to PS2 adapter for your old keyboard and computer if yours doesn't have a USB port. Leo says that if you are still using a computer that doesn't support USB keyboards, this is a good way to do so. However most, if not all, computers support USB in some form and way.
Steve's church is doing live stream using the Blackmagic ATEM Mini Pro. But he's having issues with the church's laptop, which is older keeping the stream going, while also powering a Powerpoint to project on the wall. Each will have different resolutions. Leo says that the projector is analog VGA, while the ATEM is HDMI out. The good news is that the ATEM has multiple HDMI ports. Leo suspects that the old laptop just has analog out.
Jim wants to know if he can use his old Atari gaming console with his new TV. Leo says there are ways to do it, but he will need a "composite" adapter to do it. Most modern TVs don't have composite inputs anymore. Those are the red, white, and yellow connectors. You may also need an antenna adapter. Jim will need to get a composite to a digital connector which may actually cost more than that old Atari game is worth. But he can get one from Monoprice for under $20. Don't expect great video though.
Ralph has an old HP draft plotter printer and wants to know how he can use it with a modern computer. Leo says that those old plotters used an RS-232 port and he will need to get a USB to Serial adapter in order to use it. Ralph will also need software to configure it. Leo says to do some google searching for user forums and YouTube videos to walk through it. The tricky thing may be drivers.
Frank has an iPad mini that he wants to connect to a computer monitor. Can he do that? Leo says that the iPad Mini only has a lightning connector. But you can get an HDMI to lightning adapter from Apple that will enable connecting to it. Look for an MFI certified adapter. It'll also have a lightning connector too so you can charge it as well. You can also Airplay to a TV which supports it. The iPad Pro, however, does support Type C, which connects to a monitor. Can he add a mouse? Leo says you can; it's in the accessibility settings. But it's really made to use touch.
David lives in a poor cellular area and wants to connect his phone to his home internet. But he wants to do it wired. Leo says that WiFi is pretty fast these days and that's the way to do it. He could conceivably get a USB/Ethernet dongle and plug it directly into a router. Then it depends on the phone. Samsung has a DEX adapter. Amazon sells an iOS to an Ethernet adapter with a lightning connector. It would have to be Ethernet to USB-C and the device would have to have a driver to understand it. Most phones don't expect users to do that, so there are no drivers to support it.
Christian recently bought a Lightning to HDMI cable to connect his phone to his Roku, but it doesn't work with Hulu. It only plays the sound, not the picture. Leo says it sounds like it isn't HDCP compliant. Copy Protection is probably what he's running up against. Hulu's site says it doesn't support it. There may be a workaround, though. He should try scrubbing through the timeline. According to the chatroom, 9/10 times it will bring the video back. Another solution is to log out and log back in. But if he has a Roku device, why not just use the Roku app?
Steve wants to use his lightning headphones into a regular headphone jack. Leo says he probably won't be able to do that since the Lightning connector is proprietary. Those Lightning headphones are for one thing only — for use with the iPhone. Walmart does sell a female-to-male Lightning adapter, and there's one that actually comes with the Apple Pencil as well. Leo's not sure that this would actually work, though. It may be easier to just buy a cheap pair of earbuds that would have the proper connector.
Rowan wonders if USB thumb drives are becoming obsolete like so many other data drives before it. Leo says that no format will last forever, but there's still plenty of life left in USB. We need to keep an eye on how technology progresses and transfer the data over when the time comes, though. Rowan will likely be able to get an adapter for USB-C, which is the current standard. The other thing he can do is use an open source backup, like TAR, which will make the backup easily transferrable. The best way is to go into the cloud, though. He should have both.
Warren is thinking about buying a Chromebook now that it can run Android apps. He needs to be able to connect via ethernet, though. Leo says Warren can get an ethernet adapter as long as it's compatible, and all USB to ethernet adapters are compatible with the Chromebook. BobJGear USB to RJ45 adapter is a good one and it's under $20. What about security? Leo says that Chromebooks are more secure than any other computer out there.
