Hacked rear projection
Although we seldom find anything relative to HD on Hack A Day, we love to read about all the cool projects. But today is different as someone has devised a way to take a rear projection HDTV and buy a bigger screen for it. Although we question if this is any better/cheaper than just buying a projector, this might me a good way to go if you want to reuse your old HDTV. But aside from the questionable practicality, and possible loss in brightness from this hack, it's pretty cool -- and well documented.

Hack a day DIY pre-amplifierIf you're big into do-it-yourself electronics, and feeling like your existing off-the-shelf pre-amplifier just isn't cutting it, Hack a day has the plans for you, with schematics and photos of a 7.1-channel pre-amp design sporting RCA, SPDIF, XLR, and USB inputs, and a VFD display to show you what's going on. The design is very professional-looking, and despite the glaring lack of analog tubes, it's sure to please any soldering audiophiles.
