DIY: Speakers Anything involving wires usually scares off about half the DIY population. As guys, it’s something that should be embraced rather than feared. We’re not saying you need to get knee-deep in computer parts, but some basic work would be good for you. When it results in a new set of unique speakers too, well that’s just a bonus.

Build a Programmable Mechanical Music Box Since this project was starting entirely from scratch, I needed to make a flawless design that could be easily worked with, and a good design always reduces waste. I decided to use oak, and at $60 per 10ft plank I didn't want to waste any. Also, its pretty complex and precision is extremely important for everything to work correctly.

Turn a Pair of $30 Headphones into a $300 Pair If you want high-quality music but don't feel like shelling out hundreds of dollars for a decent pair of headphones, blogger Stacy D shows us how to turn a cheap pair of knock-offs into a legit set of audiophile headphones. We've shown you lots of little tricks that improve your headphones , but if you'd really like to get your DIY on, you can mod a cheap pair of headphones into a set of high quality, orthodynamic headphones yourself. It takes a bit of heavy-duty machinery (like a Dremel), but other than those requirements, it doesn't look that difficult—it mainly consists of buying a higher quality set of drivers and replacing the crappy set's. Then, you just need some extra insulation to keep it all in place, put the headphones back together (you'll probably have to do a bit of sanding and painting too), and you've got yourself a high-end pair of headphones for less than $100 total cost.
