Turn a Nintendo NES controller into a retro USB flash drive that’s also a cultural icon. Now, why didn’t I think of this?

Build your own Capacitor

While a capacitor the size of a 2L bottle doesn’t have any practical applications, it’ll help you understand the underlying theory behind the tiny capacitors that you can actually use.

Canon D200 hotshoe GPS [link]

Great hack for Canon Nikon D200 owners: make a relatively cheap GPS that will transmit coordinates to the camera. Take a picture, and it gets stamped with the GPS coordinates. Not too shabby. I guess this would be great for traveling bloggers, photojournalists, or even artistic projects.

Cheap Acoustic Guitar Pickup

Cheap Acoustic Guitar Pickup

I love this: it’s cheap, effective and pretty simple to do. Basically, you take a 2$ Radio Shack piezoelectric transducer and use it as pickup. One thing bothers me a bit though: you need to drill a hole in the guitar to fit the jack. I’m quite sure there’s a way to go around this. And who cares, I don’t have a guitar ;)

I might build an acoustic bass out of scrap wood I have at home, and that sort of pickup would be perfect for it.

Turn a 20$ DVD player into a portable NTSC display

This sweet hack turns a cheap portable DVD player into a portable NTSC monitor. I can think of a few interesting applications: car night-vision and parking/back-up cameras, portable consoles, monitor for DIY film making, monitor for a hidden or remote (think on a kite) camera, etc. Nice, cheap and totally versatile.

Compact Powerful Weatherproof Wifi Antenna

Useful plans to build a weatherproof wi-fi antenna. Great for sticking it to the man (your ISP) and sharing the cost of your connection with a few neighbors. This design supposedly triples the gain compared to a standard antenna.
