The two Jabra Go 6400 and Pro 9400 Bluetooth headsets are kinda neat, combining a charging dock for convenience with a touchcreen for showmanship.

The 6400 has a standard Bluetooth range and looks exactly like a Bluetooth headset from Jabra, whereas the 9400 looks like a receptionist's headset that you can take around your house at up to a 450-foot range.

They both have dual-microphones for noise cancelation and both have the touchscreen to quickly switch between a cellphone, VoIP or landline connections. Both will be available later in the year for $200 each. [Slashgear]

The micro-four-thirds standard created by Panasonic, Olympus and Leica has intrigued us but its mightiest product to date, the Panasonic Lumix DMC-GH1, leaves us scratching our heads.

Camera Be Still
When it comes to still shooting, there is no difference between the GH1 and the G1 that Mahoney reviewed last November. It has a digital viewfinder instead of an optical one, which takes some getting used to but tends to work. It's got a huge number of manual and automatic options, as well as some uniquely digital settings, like "film mode" where you can manually adjust the color balance, saturation, contrast and noise reduction of the "film" you're using. Because the sensor is 4:3 (hence the format's name), you can change the aspect ratio to 16:9 for a wider view, but of course you sacrifice some pixels in the process.

The camera has many of these novel options to keep track of, but it doesn't pay a huge dividend to those who do. As Mahoney said in the original piece, its high-ISO shots are a bit more noisy than most DSLRs, and the lens selection is paltry compared to Canon and Nikon. As someone who carries mainly entry-level DSLRs (and generally wants for nothing more), I found myself simultaneously overwhelmed and unimpressed, though I did manage to eek out a few halfway decent shots, which I've stuck in the gallery below.

All of the above features and capabilities can be found on the $800 DMC-G1. What I tested, though, was the $1500 GH1, with an "H" for "Highdefinitionvideo."

It's Got an H In It
The H makes a big big difference, as David Pogue mentioned, and as Mahoney lamented.

The 1080p video is, in fact, astonishingly good, when you're shooting in the right light with a decent lens. I used two lenses, the highly functional 14-140mm kit lens, and a playful 7-14mm wide angle lens with a touch of the fisheye.

The video comes in AVCHD format, which some people don't like. I don't mind it, though when I previewed it in VLC, it appeared to have a painful amount of compression artifacts. I was going to condemn the camera for that, until I wrangled the video in VisualHub, and found that all of the playback artifacts disappeared in conversion, and probably wouldn't appear in other software. (Panasonic sent me GH1 software, but it was for PCs only, and I didn't have a chance to check it out; some of you already know what to do with AVCHD vid anyway, so I wouldn't make a big deal out of the included software either way.) As you can see in this quick up-close video of Wynona—dropped from 1080p to 500x280 and converted to FLV for your consumption—you can certainly get a lot done:

The rustling you hear is me playing with the camera strap to attract an otherwise lethargic cat's attention; over the weekend, when I shot video of my family, the stereo mic array worked well, as long as I kept my own stinkin' trap shut. Its placement, facing upwards, on top of the flash, means that the shooter's voice is far louder than that of his or her subjects.

Video certainly is the GH1's coup de grace, as others have proclaimed. Practically speaking, it's a damn sight better than the video from the Canon T1i and the Nikon D5000, which are fine for quick snips but lack the autofocus necessary for a nice fluid continuous shot (Touch of Evil opener, anyone?). The GH1 dynamically refocuses well enough, though as you can see in the Wynona video, it can't go super-macro with that 7-14mm lens.

Stupid Money
Still, we're back to the same dilemma here: If moderately video capable DSLRs are selling for MSRPs around $900 (also with decent kit lenses), how can this baby be worth $600 extra? Still-only DSLRs cost in the $600 range—how can the GH1 be $900 more than those?

It's a powerful camera, but I certainly didn't feel as comfortable shooting with it as I do with Canon and Nikon DSLRs, and the video is, after all, video. The argument for video on other DSLRs is their compatibility with all kinds of lenses; here, it's more like a decent video camera without a huge number of lenses. As Mahoney mentioned in the G1 review, you can get a lens adapter and use some nice Leica lenses, but do you really want to go to all that trouble? We'd be better suited for some a handful of interesting, made-for-micro-four-thirds primes.

Even if we get all that, though, the price remains prohibitive. If you are tempted by the video capability of this camera, you are still better suited to buying a nice DSLR and a true HD camcorder of your choosing from Panasonic or Sony or Canon. I wish I could say that the excellent 1080p video tips the scales, but it doesn't. [Product Page]

In Brief:
HD video performance is exceptional for a high-end still camera, and notably better than "competing" DSLRs

Lots of manual digital manipulation means a lot to read up on and remember—it's not easily hidden from the beginner, but in the hands of an undaunted shooter, there's a lot of potential

The camera's entry cost is far too high to justify when it's not a big winner in still shooting, and when HD camcorder prices are dropping

Like solar-powered air conditioners, this solar hand fan makes a lot of sense. Well, save for the part where you have to fan yourself.

But it is a night light, which goes great with your ensemble if you're a southern belle who's also a robot. [Lost Values via Fashioning Tech via MAKE]

Batman normally likes to stretch his legs and have trunkspace for a few accidental dead bodies. But he might pilot an ATV powered by a jet engine on a weekend at the links.

John Carnett modded brand new Polaris RZR 2-seater ATV with a grey market, 40-year-old turbine. The result is a 114db joystick-driven vehicle that spews out 1300°F exhaust to achieve around 60MPH. And it sounds glorious.

Our only regret is that Carnett was too sane to take his jet ATV over any sweet jumps. Give him time, though. A guy who builds stuff like this has to be slipping a bit. [PopSci]

The 3.1 version of the iPhone SDK is available now, bringing a couple new fixes like having the OS simulator "more closely matching the device." There are also new Interface Builder, XCode and Dashcode changes. [iPhone Developer]

The Library of Congress just made a bunch of historical videos available on iTunes U. Now you can watch the original Edison films or Book Festival videos in a "University" setting without the need for booze or girls. Yay. [iTunes]

BoingBoing Gadgets found this photo of the original original Ethernet cable at Xerox PARC, devised by Bob Metcalfe so he could rig up a local system for sharing things digitally.

The diagram below illustrates part of what he tried to set up. What it doesn't show, unfortunately, is how slow the network would have been compared to the average home network now. In your face, Bob. [BBG]

This RainBrain smart shower controller from Hansgrohe seems like one of those things that you didn't think you needed, but once you try it you can never go back to what you had before.

This thing controls music streamed wirelessly via Bluetooth, lighting in your shower and even (who'd have imagined) what kind of water is raining down on you. It even has a Scottish Shower mode, which I had to look up to find out that it meant alternating hot and cold water spray. [Hansgrohe via Trendir via DVice]

The 1969 Kitchen Computer by Honeywell was not just a fancy cutting board. It was meant to store recipes, even recommending meals from ingredients on hand. The problem is, you had to know binary to use it.

The machine's designers assumed that housewives would do all the cooking, and yet, also assumed they'd be open to learning binary: is the Honeywell Kitchen Computer the most or least sexist computer ever made? I don't know. I do know its the most beautiful minicomputer I've ever put my eyes on. The plastic chassis hid so much of the 150 pound machine's weight in its black pedestal. Then again, it could have been a lot bigger, had it had an actual user interface that wasn't binary: The $10,600 price set by Neiman Marcus included two weeks of programming lessons in a language known as BACK.

The machine itself was a 16-bit minicomputer—the class right below mainframes—and its official name was actually the H316 Pedestal. It was part of the Series 16 lineup, based on the DDP-116. (A machine most notable for its use as ARPANET Interface Message Processors, early machinations that ran the predecessor to the modern internet.)

It had 4KB of magnetic memory, expandable to 16KB, which was pre programmed with a few recipes. Its system clock was 2.5MHz. It took 475 watts to operate.

Dag Spicer, curator from the Computer History Museum, says, "None were ever sold."

He adds, in an article at Dr. Dobbs, that in the late 1960s, "with that kind of budget, the solution would likely be a live-in chef or the traditional 3x5 card file, no?"

Indeed.

The Computer History Museum is a wonderful place. If you're in northern CA, I recommend you find a way to stop by. We'll be running pieces from their collection as an ongoing series called Computing Classic. Special thanks to Fiona Tang, John Hollar and the amazing Dag Spicer for their help.

Not to turn this into a secondary job board for Apple or anything, but they're opening up a position for a digital 3D modeler/CAD sculptor to create renderings of possible and future products. It's interesting because the turnover there for the position is really low, and it may be the only time you get a chance to get into that position for a few years. Plus, it pays quite a lot more than usual design jobs. [Dezeen via Cultofmac]
