Here’s something that may be of interest to all the reprappers, vacuum formers, and other plastic fabbers out there: ultrasonic welding of plastics. If you’ve ever wanted to join two pieces of plastic without melting them together with acetone or screwing them together, [circuitguru] is your guy. Ultrasonic welder setups are usually reserved for companies that [...]
Photo: Scott Andrews/AP 2009: Barack Obama is inaugurated as the 44th president of the United States in the first such ceremony to be widely streamed live over the web. Over 1 billion people are estimated to have watched the inauguration on their TVs and computers, with nearly 2 million people crammed onto the National Mall. [...]
Here’s one way to really keep the component count low. [David] developed an NES controller that doesn’t use any buttons. The copper clad has been milled to provide a pad which registers a button push based on capacitance. The board has a SIL header at the top, making it easy to plug into the Arduino [...]
[M. Eric Carr] built this a long time ago as his Senior Project for EET480. It’s an electronic version of the ball-in-maze game. We’ve embedded this video after the break for your convenience. The game has just one input; an accelerometer. If you’re having trouble visualizing the game, it works the same as this Android-based [...]
Regular reader [MS3FGX] recently wrote a guide to compiling OpenWRT from source. You may be wondering why directions for compiling an open source program warrant this kind of attention. The size and scope of the package make it difficult to traverse the options available to you at each point in the process, but [MS3FGX] adds [...]
We know some folks are very upset by the scrapping on vintage hardware, so let’s all observe a moment of silence for this NES controller. Now that that’s behind us we can live vicariously through [Burger King Diamond's] project. He polished up the NES controller and repurposed it as an enclosure for a portable MP3 [...]
One of the perks of writing for Hackaday is that we often find hacks that we’ve been meaning to do ourselves. Here’s one that will let us fix our borked ASUS computer monitor buttons. [Silviu] has the same monitor we do, an ASUS VW202, and had the same problem of stuck buttons. We already cracked [...]
[George] is a Neo Geo aficionado, and among his collection of paraphernalia, he has a MVS-Mini game console. His mini “Multi Video System” is a 2-slot model, meaning that it can hold two game cartridges at a time, which are indicated by plastic cards inserted in the cabinet’s face plate. Instead of swapping those cards [...]
When [trandi]‘s wife saw a cute night light at Ikea, she had to have it. She actually bought several of these for when her husband would inevitably crack one open and start tinkering with the microcontroller inside. The inevitable hack is pretty cool, and also gives us some ideas for interfacing with Android on the cheap. [...]
[Ranger Bob] crafted this great looking Reverse Geocache box. Our favorite feature is the black piece of acrylic on top. It’s laser cut (not sure if the letters are engraved or not) and gives a great finished look while hiding a couple of things at the same time. The orange box is a metal cash [...]
