PopMech Project
But why buy when you can build one that not only blends in with your décor but also will impress your friends? With a little imagination, just about anything can become a Bluetooth speaker. Lunchbox? Broken ukulele? Jewelry box? Busted antique radio? An old Tonka truck? How about a desk, or a bookcase? The answer to all is yes.
The parts for this 50-watt Bluetooth speaker project aren't expensive, and the process isn't very difficult. If you have basic supplies like speaker wire and solder, it'll cost just under $100. Small circuit boards for Bluetooth receivers with built-in amplifiers are relatively easy to find. The biggest challenge people usually encounter is cutting holes for speakers and then making them look presentable. Our project utilizes sound exciters, or transducers, which vibrate, causing anything they are attached to become a speaker. Basically, they're the back part of a speaker without the cone. These eliminate the need to cut holes for speakers and free you up to use a variety of things that can project your music or podcasts.
For our project, we chose a 1970s-era, plastic Samsonite suitcase. The broad, flat sides will vibrate easily and project sound well. We've also made Bluetooth speakers from old cigar boxes, antique box cameras, and desktop shelves. Also, placing exciters on the bottom of a desktop or on the back of a shelving unit is a simple way to blend the speaker into your décor.
Below we've included a list of parts, but once you know what you'll turn into a speaker, search for the best components for your project. The steps will be basically the same, except for the location and method of securing the components.
INSTRUCTIONS
Step 1 Assemble the Bluetooth receiver
Follow the instructions included with the receiver.
Step 2 Test the receiver

Whether We Live in a Simulation - scientist Melvin Vopson, PhD, studies this exact thing- the possibility that the universe might indeed be a digital facsimile. And he claims to have evidence.
In the 1999 film the Matrix, Neo discovers A truth to end all truths-the universe is a simulation. While this premise provides fantastic sci-fi fodder, the idea isn't quite as relegated to the fiction section as one might expect. . In fact, University of Portsmouth scientist Melvin Vopson, PhD, studies this exact thing- the possibility that the universe might indeed be a digital facsimile. And he claims to have evidence.
The Ancient Language of Easter Island - Today, humans inhabit- or have, at the very least, explored- pretty much every corner of the planet. But that immense proliferation of Homo sapiens across the globe was a slow process.
With the first humans leaving Africa between 60,000 and 120,000 years ago, the species slowly spread across the Earth over many millennia. And one of the last places these ancient humans made their way to was the southeastern Pacific island of Rapa Nui, known more broadly as Easter Island.Located 2,360 miles off the coast of Chile, Rapa Nui is one of the most isolated places in the world. Its native people, who are also named the Rapa Nui, first arrived on the island's shores between A.D. 1150 and 1280, and lived in isolation until the arrival of Dutch navigator Jacob Roggeveen in 1722.
Underwater UFOs - A retired U.S. Navy admiral believes that the government should look to the oceans to help solve a mystery in the skies.
A retired U.S. Navy admiral believes that the government should look to the oceans to help solve a mystery in the skies. Rear Admiral Timothy Gallaudet, former Oceanographer of the U.S. Navy, recently published a paper arguing that unidentified anomalous phenomena (UAP, more commonly referred to as UFO) and unidentified submersible objects (USO) are linked, and should be studied further.
Synching Up Our Circadian Rhythms - If you've ever done any kind of long-distance travel, or just woken up feeling under-rested thanks to daylight saving time, you know how important your circadian clock is.
If you've ever done any kind of long-distance travel, or just woken up feeling under-rested thanks to daylight saving time, you know how important your circadian clock is. Like many things in your body, your circadian rhythm is more complicated than it might seem on the surface. Rather than being entirely brain-based, it's actually controlled by a collection of several circadian clocks (central and peripheral) that all work together to keep your gears turning like a well-oiled machine.
