Fresh hacks every day
Video distribution amplifiers are used to amplify a video signal and split it into multiple outputs so multiple displays can be driven. They are also used to correct the gain of an incoming video signal. [Andrew] was having trouble with the video signal from an interferometer, and found the issue was caused by a low output gain. His solution was … Read the rest
AirPlay is a great system. It allows you to send whatever media is playing from one device to another. Sure, we wish it were a bit more open (Apple is certainly not known for that) but there are several option for creating your own AirPlay receivers. After coming across a project that does just that, [Matt Shirley] decided to turn … Read the rest
[Dino's] kitchen skills match his hardware hacking prowess. Look really close at the image above and you’ll realize this collection of transistors and passive components is edible. Rather than decorating cookies for the holidays he built this audio amplifier from gingerbread, icing, and candy.
The thing is, [Dino] almost always has that extra touch to his presentations. If you … Read the rest
Here’s an exercise in excess if we’ve ever seen one. While working on his undergrad at Michigan State, [Gregory] thought it would be a great idea to build an all-tube home theater system. He calls his seven-foot tall rack of amplifiers ‘Frankenstein,’ and we’ve got to agree this build is an impressive monstrosity of engineering prowess.
[Gregory]‘s Frankenstein is … Read the rest
While you won’t catch us in an argument with an audiophile regarding the sound quality of tube vs. solid state amps, there is a general consensus that tube amplifiers sound much better than their transistorized brethren. Actually building an all-tube amplifier, though, is a bit harder than one built around common ICs – there are transformers to deal with and … Read the rest
Here are two different briefcase speaker projects. [Dale] built the offering on the right back in high school and the upgraded version 2.0 more recently. He was inspired to send in a tip for the projects after seeing yesterday’s suitcase full of tunes.
The first version uses a pair of speakers pulled out of a car at the junkyard. … Read the rest
Take the party with you by building your own boomcase. It’s an amplifier and set of speakers built into luggage. It uses an audio jack to connect to your favorite music player, and with a bit of added protection — like grills for those speakers — it could still be gently used to transport your wardrobe.
A 1960′s suitcase … Read the rest
