Fresh hacks every day
If you know your way around a pool table you should be able to apply those skills to improving the sound of your home theater. [Eric Wolfram] put together a post that discusses the issues caused by unwanted sound reflections and shows how to position acoustic tiles to solve the problem. This is a companion post to his guide on building your own acoustic tiles. Don't worry if you haven't gotten … [Read more...]
[Vinod Stanur] just finished another hobby project by building a WAV audio player using a microcontroller. He had started development a while back using a PIC microcontroller. But the chip he was using didn't have enough SRAM to allocate as a playback buffer. When he got his hands on an ATmega32 his mind turned back to the project and he saw it through to the end. He takes advantage of what he … [Read more...]
Wardriving started out as a search for unprotected WiFi access points before hot spots were prevalent. And so this ZigBee protocol wardriving hardware which [Travis Goodspeed] put together really gives us a sense of nostalgia for that time. Don't get us wrong, we love our pervasive WiFi access and don't wish to go back to simpler times. But if the radio signals your looking for are scarce, … [Read more...]
[John Philip’s] brother has a sizable room set aside for his model railroad setup, and he was looking for something interesting to add to his brother’s collection. Rather than construct something for the railroad itself, he decided that an early 1900’s-style semaphore railroad signal would make a great novelty item for the room. The project started with [John] scouring the Internet for … [Read more...]
The Earth orbits the Sun every 365.256 days. Because this number isn't a whole number, an extra day is tacked onto February every four years, unless the year is evenly divisible by 100, except in cases where the year is divisible by 400, or something like that. To commemorate this calendar hack, here's some stuff that has rolled in over the last week or so. Marble sequencer [Brian] sent … [Read more...]
If you are thinking of building your own flight/racing sim setup at home, you might want to check this out. [Alex] from the Garoa Hackerspace in Säo Paulo, Brazil put together a slick setup that makes projector image calibration a breeze. When building a wraparound screen for such a simulator, you are likely to run into problems with both overlapping images and distortion from the curved … [Read more...]
The Raspberry Pi has been launched. When we first heard of this board nearly a year ago, the idea of a $25 computer that displays 1080p video, runs Linux, and has enough ports to the outside world to do some very interesting stuff, we were cautiously optimistic. Now that the guys behind the Raspberry Pi are getting units out to the masses, we're a little excited and also thinking about all the … [Read more...]
