Lithophones - Instruments Made of Fossils, Floor Tiles, and More

Musician, artist, and "edutainer" Tom Kaufmann makes unique instruments called lithophones, which are similar to xylophones, but created from various stones. Here's how Kaufmann describes them:

Another happy coincidence led me to my current fascination with constructing lithophones. I was tossing around some scrap pieces of granite countertop that I’d gotten for one of my Upright Furniture projects, and as one of the chunks landed, it rang as clear as a bell.

I’d been looking for stone suitable for building lithophones for a while, but never suspected I would find a source of such readily available and inexpensive material.

Litho is Greek for stone, and phone is sound, so a lithophone is a musical instrument made from stone. They are one of the most ancient instruments, and in China the sound of stone is as elemental as metal or wood. In Viet Nam a stone instrument called a “dan da” was found that is believed to be over 9,000 years old. Western civilization didn’t use stone for music until the 1840’s. There are links to some great sources of information about lithophones at the bottom of this page.

Here's Kaufmann playing the "Flintstones" theme on a lithophone made from Michigan's State Stone: Petoskey Stone (fossilized coral that lived 350 million years ago). By the way, did you know Michigan had a State Stone? Enjoy:

Floor Tiles & Wrenches

Not all lithophones are made of such exotic materials. This video shows a series of lithophones made from floor tiles, then a toolbox glockenspiel (made from wrenches and bolts, complete with some mild tuning problems):

Limestone

Here's Kaufmann playing his "park bench lithophone," made from scrap limestone. Yes, he plays the "Flintstones" theme again:

Granite

This lithophone is made of granite. From Kaufmann's website:

Here’s a video of my newest lithophone, built for the Children’s Garden at the Charlevoix Public Library, in Charlevoix, Michigan. This one octave diatonic instrument, made of granite and mounted on a powder coated steel base with stainless steel bolts, is tuned to the key of C, A=440

Slow Wi-Fi? It Could Be Your Neighbor's Fault

If your Wi-Fi connection remains interminably slow no matter how many times you restart it, you can probably blame your neighbor. It could be that there are too many people using Wi-Fi connections on the same channel, even if you're all on different networks. But, as Tech Insider teaches us in the video below, there is a way to circumvent this, returning you to the prime TV-streaming Wi-Fi speeds of your dreams. (These instructions apply to Mac users, but if you've got Windows, How-To Geek recommends a tool called the Xirrus Wi-Fi Inspector to do the same job.) It seems like a lot of steps at first, but it'll be worth it—we promise.

If you’ve got a Mac, hold the Option key while clicking the Wi-Fi symbol in your top menu bar. Go to “Open Wireless Diagnostics,” then when that opens, go up to the top left menu bar and click the drop-down menu “Window > Scan.” That will open up a window with all the nearby Wi-Fi networks. Click the “Scan Now” button on the bottom right, and your computer should recommend the best channels for you to use—say, you’re on Channel No. 1, but the best 2.4GHz channel is No. 3. Tech Insider recommends writing those down (there are options for both 2.4GHz channels and 5GHz channels).

Now, you’ll need to break out your iPhone. Download the AirPort Utility app, and go to your phone’s settings. Scroll down to the AirPort Utility app in your app list, and enable “WiFi Scanner.” Use the app to scan your house for Wi-Fi networks and note which channels are commonly used by your neighbors’ networks. (If you don’t have an iPhone, you can also use Acrylic Wi-Fi for Android or Windows phones.) This will help you avoid the most congested networks.

Then, log onto your router on your computer by typing your router’s IP address into your browser, just like you would any web address. From there, go into Wireless Settings, and change the channel your network operates on to one of the recommended options that you wrote down from your computer's diagnostics window earlier. And don’t forget to save!

This should help you get a faster internet connection by minimizing the amount of interference from other networks around you. Because the best neighbors are the ones who don't slow down Game of Thrones for you.

See the process step-by-step in the video below.

This 'Smokeless' Fire Pit Promises a More Efficient Burn

For thousands of years, people have gathered around open flames to cook food, find warmth, and share stories deep into the night. Campfires have been around since the dawn of humanity, but what if there was a way to use modern technology to make them even better? The people at BioLite believe they've found one.

The FirePit is the outdoor gadget startup's answer to the recreational, backyard fire. It offers the same benefits as a more conventional product: a space for building wood or charcoal fires, a removable grate for grilling, and metal screens on each side to protect onlookers from embers. But the yellow battery pack is what sets it apart from anything else on the market. With the press of a button, a fan inside the FirePit stokes a hotter, more efficient blaze without producing all of the smoke and soot people are used to.

"Air injection makes the fire burn more completely," Ryan Gist, one of the lead engineers on the project, told Mental Floss. "So you basically get all the energy out of your fuel." The result is a fire you can enjoy without worrying about your eyes and throat burning, moving your chair every five minutes to avoid a gust of smoke, or having your clothes stink for weeks.

It also makes for a fire capable of burning longer and brighter with less wood. Smoke is made of tiny fuel particles that haven't fully burned up. Using a fan, the FirePit can draw that runaway fuel back into the fire before it has a chance to escape. "It's like when you're stuck on the highway behind a truck and it's got black stuff coming out of the tailpipe," BioLite marketing director Erica Rosen told Mental Floss. "When you see black stuff coming out of a fire, it's the same thing. So what we've done is, we've given fire a tuneup."

FirePit's built-in fan makes the fire easy to control. If campfire gazers want to see big, roaring flames through the box's X-ray mesh, they can turn the air down low. The higher fan setting produces a smaller, more intense burn, which is perfect for chilly autumn nights. Adjusting the blaze can be done remotely with the BioLite Energy app or manually from the control panel on top of the battery pack.

BioLite designed the FirePit for backyards, but its foldable legs make it convenient to carry to the beach, a campsite, or anywhere else where you might bring a cooler of the same size. Once it's cooled down after an evening of grilling hot dogs and toasting marshmallows, the pit fits neatly into its solar panel case, where it can recharge in time for the following night (the battery also features a USB plug for charging indoors).

The FirePit recently debuted on Kickstarter, where it's available along with its solar carrying case for a special deal of $169 (once the first 300 FirePits go, it will be sold for the regular price of $199). To help the campaign reach its $100,000 funding goal, you can reserve yours today with shipping estimated for May of next year.
