How can I get TV stations over the air?

TV Antenna

Episode 1636

Timmy from Oak Hills, CA

Timmy wants to know if there are plans to build larger antennas so he can get stations in a remote area. Leo says that the broadcast licensing is by the FAA and TV stations usually have the largest, most powerful license you can get. So if you can't get reception in a weak area, that may not be possible. But check out two sites - AntennaWeb.org and TVFool.com. Both can give you data on what stations you should be able to receive, and offer suggestions of what antennas could help.

How far can a WiFi Security Camera signal go?

WiFi

Episode 1636

Todd from Portland, OR

Todd has built a WiFi based security system and he's been able to get reception at a distance of a half mile. Leo says that's incredible. But if you have an unobstructed view line of sight, it may happen. But any kind of metal in between can cause that range to lower, or the bandwidth quality to drop, especially when transmitting video. Leo says you could try moving the stations around to get a better line of sight connection.

Why is my Mac Air so slow?

Macbook Air

Episode 1636

Mark from Tustin, CA

Mark's Mac Air is slowing down and he wants to know if there's an app like SpinRite that can run them. Leo says that sold state drives (SSDs) use TRIM, or wear leveling to keep your SSD in good shape.  It doesn't need to be defragged directly. But it will trigger the controller to run the TRIM utility. Search for TRIM in macOS. But it should happen automatically. If your OS is older though, you may need a third-party app to do it. 

TRIMFORCE Enable is the command you can use in the terminal. That could speed it up.

Virtual Reality Desktop?

Oculus Quest

Episode 1635

Grant from St Paul, Minnesota

Grant is interested in a Virtual Reality desktop experience. Microsoft was looking to push that idea with their Hololens for VR, but Leo believes they are backing off on that idea as people believe there's still a ways to go with VR. Having to wear VR goggles for so long can potentially make you sick and that you can't see the world around you. Augmented Reality, or Mixed Reality as Microsoft is calling it, is a possible fix around Microsoft is pushing since it overlays information onto your display while enabling you to still see the world around you.

What's a good PC to use with a teleivison?

Episode 1635

Lenaea from Carlsbad, California

Lenaea is looking for a new PC to use with two 60Hz televisions. Leo doesn't recommend using a television as a computer monitor, as TVs aren't generally designed to be used with computers. It can be hard sometimes to read font or text on televisions if you're reading a news article or post.  But with technology becoming more advanced within televisions, you can do it if you choose. 

Twistedmister in the chat found an article about Chrome Subsampling that would help with the television.

The Giz Wiz and the Jooki

Dick

Episode 1634

Jooki is a music player that lets kids play parent-approved music and stories from Spotify & more. It comes with 5 characters (like fox, whale, etc.) that link to various playlists. When a kid pop one of them in the center ring of the Jooki, it starts to play the music, story, etc., that has been uploaded to that character. The company says there's 8-hour of battery life (there's no screen to suck up battery juice), which means very long playtime outdoors or on the go. There's a small amount of onboard memory but there's an SD card slot to add more.
