Fresh hacks every day
The PhorsePOV by [Julian Skidmore] almost slipped by, but we thought it was a nice easy hack for your Memorial Monday. The gadget uses an ATTINY25 to drive 6 LEDs aren't standard characters 7 units high? Which when waved in the air produces a readable message. What we were really interested in is the use of a single button for text entry, called Phorse code, or an "easier to learn and remember" … [Read more...]
There's a million tutorials out there describing how to use shift registers. If you're just getting into embedded systems you should know how to use them as they allow you to take three microcontroller pins and expand them virtually without limits. This is due to the serial-in parallel-out nature of these integrated circuits. A key feature of these chips is the ability to overflow, or cascade to … [Read more...]
[Nathan] took this boombox and outfitted it for Bluetooth streaming. He took a Motorola DC800, which is meant to make headphones wireless, and connected it to the stereo inputs. The controls for the Bluetooth module were routed to the stock tape deck controls and a little bit of frosted spray paint adds a blue glow to the cassette window. Now he can stream music from his phone, including internet … [Read more...]
Turn your volume down and take a look at the brick sorting robot in the video above. It's built using LEGO and powered by four different NXT modules. It sorts differently colored bricks on the intake conveyor and places them on three output conveyors. The build is solid and was [Chris Shepherd's] impetus for starting a blog. We appreciate the pneumatic tricks that he detailed in some of his … [Read more...]
[Rafael Mizrahi] built a flight simulator that lets him fly like Ironman. As you can see in the video after the break, the hardware involves an automotive crane, hang gliding harness, plus the wings and tail from a UAV. A giant fan pointed at the wearer allows him to use the wings and tail to maneuver while the Wii remote strapped to his chest tracks the movement and feeds it to Google Earth … [Read more...]
[Sam Seide] dropped us a line about his new arcade creation. We loved his Punch-Out build that used a punch dummy as a game controller. This time around he's made some mini-cocktail style MAME cabinets. He removed the screen from a netbook and placed it face-up underneath the acrylic bezel. There are controls on either side for two players as we would expect from any quality cocktail cabinet. The … [Read more...]
Tired of the disappointing performance from the crossfader on his Numark MIXDECK, [dj JD] cracked it open and made the crossfade curves adjustable. It's a super-simple hack that just introduces two 100k trimpots to the crossfade slider. The change led to a higher volume level on the current channel until the slider was much nearer to the center. The added adjustment feature might be nice to have … [Read more...]
