Do-it-yourself cheap, easy mobile Wi-Fi access point

Do-it-yourself cheap, easy mobile Wi-Fi access point

12-ArtsyNathan True’s excellent mobile hotspot – “Wouldn’t it be great if I could just plug my phone in… and have it automatically connect to the phone and serve its sweet, sweet Internet over a Wi-fi connection? Better still, have it transparently proxy all connections so that nearly all Internet programs will function properly? Maybe even prioritize certain types of traffic, or encrypt everything so my wireless carrier can’t spy on what Slashdot stories I like to read? All of those things would be just great. And all of those things are exactly those things which I set out to do (and/or enable you to do!) in this project. ” [via] Link.

Hackable Windows PC / Synth / Entertainment Center

Hackable Windows PC / Synth / Entertainment Center

MikomoviePeter writes “Korg has kept its OASYS Linux PC – synth hybrid closed, but not Open Labs. Their Windows-based synthesizer keyboard slash DJ/VJ workstation slash home entertainment center (with remote control) has an open hard drive bay, four PCI slots, and hinged access to the PC innards, all with a fully-customizable Windows install. Sure, it’s preconfigured for music production with a 15″ touchscreen and software bundle, but you could go inside the machine and reconfigure it into whatever you wanted. One idea: control games from the music keyboard.” Link.

Make your own video streaming server with iTunes 6.02…

Itunes-1Fsteele writes in to confirm you can stream purchased video with the new iTunes – “Thanks for the link; it works just fine with store content. That’s actually how I noticed it. I’ve successfully imported content I captured via EyeTV, as well, but it looks like it only works if it was imported via iTunes 6.02. My wife has a couple of videos she bought with 6.01 that aren’t available. What really makes this cool is that there’s now a video streaming server inside every copy of iTunes, so it will be interesting to see what people can do with that.” Link.

Turns out we all want to pay *more* for ringtones?

ImagesMakers, are you OK with paying more money for ringtone than you would for a complete song? These folks seem to think so – “According to The NPD Group, a leading provider of consumer and retail information, consumers are willing to pay more for a 30-second snippet of a song track to be used as a ringtone than to download an entire song track. In addition, consumers are willing to pay a premium (above the average $0.99 price for paid music downloads from the Web) for the convenience of downloading a full song directly to their mobile phone wherever and whenever they want.” Link. Wouldn’t it be better to buy the song, then make your own?

iTunes 6.02 has video sharing…

Browse-1News to me, the Digg folks are on it “With all the attention on the new ministore presentation, no one seems to have noticed that iTunes 6.02 enables video-sharing to your local network. Whether it’s intended for an upcoming home media appliance or not I don’t know, but it brings videos up to par with music.” Link. I think we’ll see an Airport express AV to stream video to our TVs soon. I need to try this out and see if it works with purchased video, I’m guessing no?

HOW TO – Make a LCD Cover

HOW TO – Make a LCD Cover

Lcd FrameMat_the_w writes “Everybody loves LCD monitors because they are so portable and perfect for LAN parties, but I am always afraid of something falling and damaging the soft screen when I travel with my LCD. After purchasing a nice 19 inch Dell display, I decided I needed something to protect my investment. I cut and molded a piece of acrylic plexiglass to form a cover for my LCD monitor.” Here’s the how-to on Instructables. Link.
