Most of us have conducted an investigatory science project without even knowing it, or at least without knowing that's what it was called. Most science experiments performed, from elementary to high school students and all the way up to professional scientists, are investigato ...more
While music may not technically be a "universe language," it is the one language listened to by all. There are over 1,500 music genres today—rap, classical, rock, jazz, trap, hip-hop, house, new wave, vaperwave, charred death, nintendocore... and the list goes on. And if you'r ...more
In this article, I'll show you how to build a simplistic circuit to generate negative ions. Negative ions have been known to contribute to fresher air, happier mood, and general health benefits. However, they also look amazing in the dark (check out the photos below, purple pl ...more
In this article, I'll show you how to built a Wireless Transfer of Energy Transmitter. Simply put, this device will send electricity to a florescent light bulb and light it up, from up to three feet. The idea originally (at least, prominently) came from Nikola Tesla (read more ...more
If you're ever lost or hurt out in the middle of nowhere with a dead cell phone, you might be able to "flag" down help as long as you're near some railroad tracks. Some train tracks carry a small electric charge as a means of detecting other trains for signaling or for detect ...more
Kipkay teaches you how to make a USB cell phone charger and first you need a standard USB cable. Cut off one end of the cable and use a voltmeter to check which of the four wires has five volts.
For this tutorial, you will need some water, table salt, a few square feet of aluminum foil, a needle, some steel wool, a pair of wired alligator clips, a thick paper towel and a voltmeter to test out your new battery.
One of the most popular usages of modern-day smartphones is listening to music. It doesn't matter if you download or stream your tunes, you are part of a massive group of users who do exactly the same. While statistics are a bit foggy on how many smartphones users download mus ...more
Born in 1975, the world's first digital camera used a standard cassette tape to record images, rather than today's standard data cards. Vintage 1975 portable all electronic still camera. Via Kodak, Steve Sasson, the inventor of the digital camera, describes it's inception: "I ...more
This video demonstrates how to make cotton candy using the Gold Medal X-15 machine. Plug in the three-prong chord in its own independent jack. Use a heavy duty three-prong extension cord if needed. Remove the clips from the net and spread the net around the inside of the pan, ...more
Most use wireless computer mice these days for their computers, but there are still people stuck on wired optical mice, especially in an office environment. Those people are our targets. As pranking someone's computer may be frowned on, peripherals are fair game, and this pran ...more
With a voltmeter, you can safely check the AC and DC voltage levels, measure resistance and even measure amperage or give circuit readings. What this means is that you can use this to diagnose problems that some of your household appliances might be having.
This video explains how to diagnose a cranking circuit with a voltmeter by doing voltage drop testing.
