Fresh hacks every day
Upgrading a desktop with a diamond cutting wheel [Michail] needed a new graphics card. The only problem was his motherboard didn't have any free PCI-E x16 slots available. Unable to find a PCI-E x1 card, he did what any of us would do and broke out the Dremel. Yes, he got it working, but don't do this unless you know what you're doing. It's recycling! [Steve] recently got a Galaxy S3 and was … [Read more...]
Hey, it's the 43rd anniversary of men first walking on the moon. Here's some stuff we found to celebrate that. Fun trivia: for Apollo 11, [Neil] and [Buzz] didn't go more than 200 feet from the LEM. This is so incredibly sad Remember Heathkit? A lot of cool kit-based electronics came from them. They're out of business, but you can get all the Heathkit swag you can imagine from the repo … [Read more...]
Here's a brain bender for you: YouTube user [Fredzislaw100] put up a video of six LEDs and six switches wired up in series. After soldering a resistor and 9V battery connector, the first switch turns on the first LED, the second switch turns on the second LED, and so on for the rest of the circuit. We've seen this trick before from [Fredzislaw100], only this time he's moved up from 3 LEDs to … [Read more...]
A month ago, we saw a marvelous demonstration of troll physics from YouTube user [Fredzislaw100]. In his video, we saw a circuit of three switches and three LEDs wired in series and but not acting like the should. A lot of the comments for this post elicited reasonable explanations like modifying the battery or pure camera wizardry via After Effects. Thankfully, [Alan] stepped in and … [Read more...]
Last month we caught wind of an impressive display of troll physics. [Fredzislaw100] out of Poland posted a video of a circuit that should not exist. As expected, the comments in our coverage blew up with 200 posts. About half the commenters called a little Adobe After Effects trickery, while the other half offered up an electrical explanation. We're happy to report that [Alan] successfully … [Read more...]
[Martin] sent in two videos he found while cruising the tubes. The first video is a simple circuit with a resistor, three switches, and three LEDs. All the components are soldered together right in front of the camera. When a battery is connected, turning the first switch on makes the first LED light up. Turning the second switch on makes the second LED light up, and the same thing goes for the … [Read more...]
