Portable wireless backpack takes pictues and keeps you stylish

web_diagram.jpg


The PORTA2030 from 2006 is a mobile data sensing storage transmission unit that consists of a wireless hard drive (the WL-HDD2.5), a 1 GB flashcard and an open source backend. The device functions as a portable data sensing storage transmission system that can stream images to function as a simple communications device. Interesting design but we wonder how different it is from what a typical cell phone can do these days.

Stanford Cool Products Expo

2405180896_d6b59873eb.jpg At first glance, Stanford's Cool Products Expo looked like a regular college career fair. That is, until I saw the solar-powered car, tilting trike, Tesla car and BMW's hydrogen car parked on the lawn. Inside the packed hall, instead of suits touting companies there were dozens of, well, cool products. They ranged from a design student's clever silicone vegetable steamer to Belkin's newest remote control energy-saving surge protector. I loved that there was a broad mix of stuff, ranging from out-there prototypes to quite polished final products already on the market. (The most fun to look at were of course the former.)

How did they choose what to include? As Tom Nguyen, one of the organizers, put it in an email: "Well, they have a cool-factor that requires no explanation (you'll know it when you see it), they're radically new rather than improvements on existing products, and they represent an essential combination of design form and function." (By the way, that's him up above with Joe Wilcox's fun-to-ride Tilting Trike.)

Here are a few of the things that really stuck in my mind (and more in my Flickr set).

2405182444_41ebb33f11.jpg Brent Teal is a total maker--he built this Glide Cycle prototype in his garage after a friend of his wanted to continue jogging despite his bad knees. It's like a cross between an elliptical machine and a bicycle--the demo video is hypnotic. Elliptigo
2404360585_009c396e12.jpg I've fantasized about wireless chargers for years, so it was a thrill to see one in action. You buy WildCharge cases for your various devices, and then you lay them down on the charging pad. Voila! Maybe not the most efficient way to go, but it is cool.
2405187520_63804d6237.jpg Speaking of chargers, this one was also nice: the HY Mini, which allows you to charge up your cellphone with either a tiny solar cell or a mini fan. Jason Wang was manning the table when I stopped by, and he said he charges his cellphone as he drives to work by sticking the fan on his car.
2405186546_ee9b2ba7db.jpg On the non-commercial side of the spectrum was the Embrace Infant Thermoregulator, which replaces expensive incubators with a simple, portable $25 sleeping bag with a phase-change material insert.
2404358913_c18c070cd0.jpg And I totally loved MagnoGrip's awesome magnetic belt clips, tool pouches, carpenter belts, and other construction accessories. Suspenders are cool again!

Nintendo DS controlling a printer carriage

Raul Aguaviva made this connection between his DS and printer to control its stepper motor. He updates the script over the DSs wireless connection. All it needs now is to be able to read PostScript, and you've got a wireless printer!

Adding a removable antenna to your WRTSL54GS

wrt54-bare_board.jpg

Paul Asadoorian and Larry Pesce, authors of Linksys WRT54G Ultimate Hacking, wrote in with this excellent hack:

Over the past few months I've been contemplating a few projects for some WRTSL54GS routers with OpenWrt, however I really need these to have a high gain antenna on the WRTSL54GS. As you may recall, this model has a fixed antenna, with no option for adding one. I decided that I needed to fix that "design flaw".

Pretty nice; it lets you reuse antennas from some other Linksys gadgets.

Use a CB radio to order a Whopper

This hack shows how to modify an old CB radio to broadcast on the channels that fast food restaurants usually reserve for their drive-thru windows. Although we here at MAKE don't condone this particular use, it's still a valid way of modifying existing systems to create new opportunities for interaction on open frequencies.

Bicycle rim antenna

Bike Rim Antenna-2
Bike Rim Antenna Detail-1

Keep an eye out for good salvagable parts, especially around spring cleaning time -

Several months ago I was walking home from the post office, nearing my place I saw it was "clean-up week", the curb dotted with various piles of junk people had put out to be disposed off by the council pickup. The pile outside my block of units had mostly busted furniture, but one item caught my eye, an Aluminium bicycle rim. I dug it out and took a closer look. The spokes and hub were all rust-pitted chromed steel, and physically it was for a child's bike, only around 580 mm in diameter, but the Aluminium itself looked to be in good shape. Antenna was the immediate thought, so I carried it back to the shack.

RFID and art interviews


0aabraceletrfid.jpg

Regine at We Make Money Not Art has a great set of interviews up with artists using RFID. She writes:

I interviewed 5 artists (Paula Roush, Doria Fan, Joshua Klein, David Kousemaker and Meghan Trainor) as well as our favourite expert from Tokyo (Konomi Shin'ishi) about their experience with RFID technology. What comes below doesn't reflect my presentation which was focusing on the ethical and cultural implications of the technology. I used these interviews as background research and thought they might be useful mainly for the workshop participants but also for some readers

The words of these artists are inspiring and it's great to see what they're up to. Check it out!

Live-video-rocket readies for launch

video_rocket.jpg From the MAKE Flickr pool

Member Mister Biggs scored a $30 wireless camera/receiver combo (cheap enough to put into harm's way) and integrated it into into his first stab at a live-video-transmitting rocket. His description -

Estes Canadian Arrow upgraded to accept E class engines, 1-inch fin extensions to increase stability, Kevlar shock cords for two rip-stop nylon 18" paracutes...one for the body tube, and one of for the nosecone camera assembly.
Nosecone Kevlar cord is attached to the tip of the cone, to allow for downward-facing video during decent.
Best of Luck, Biggs!

Design LEGO creations on your iPhone or iPod Touch


legoiphone.jpg

LEGO-touch is an application for designing LEGO creations on your iPhone or iPod Touch. From the website:

View, post, build, or edit other LEGO maniacs projects. Create your own LEGO characters in pals, post your LEGO self to represent in share. Play and download different LEGO games or challenge anyone to a build-off! Personalize your bricks with color-slider and more...

The community aspect of this software seems pretty interesting to me; collaborative designs, perhaps! - Link.

ExploraBot

Here is a great way to spy on people survey your surroundings. With Bluetooth integration, it is completely wireless and is controlled by a video game controller. The camera movement is very fast, but unfortunately the bot isn't. Keep this in mind, since a fast escape after being detected is not going to happen.

For this bot I needed another axis on a joystick. I have a Logitech game pad that was ideal for this. The left thumb pad drives the motion servos, and the right thumbstick moves the turret. 2 buttons are used to control the servo that opertates the light, one for on, the other for off.

Sniff wireless video cameras with 2.4Ghz

twopointfour.jpg

Although there have been a lot of projects that have used the 2.4 GHz signal to snoop on wireless cameras (such as Life a User's Manual and the Radical Software Group's "X-10-1", Ben Gaulon's (aka. Recyclism) "2.4GHz Project" is a nicely designed way of surveilling surveillance cameras. Check out more pics at the link below.

Sensor squid relation game



sensorsquid.jpg

My colleagues and I in the Arts, Media and Engineering program at Arizona State University are working on a wireless tangible interface object for collaboration, called the Sensor Squid. It's basically an Arduino-controlled, Bluetooth communicating 6-foot plush cephalopod used to control a Max/MSP game about community-generated media. You can download the code, parts list, and schematic. - Link & more.

HOW TO - Build a beer keg radio

Make Pt0241-1
Here's how to build a beer keg radio from Popular Science 1938 -

NOVEL as well as serviceable, the beer-keg radio described on these pages will make a useful addition to the furnishings in your game room. It can be used either as an end table or as a refreshment stand, and, since it is an entirely self-contained unit, operated by dry batteries, it can be carried onto a porch or even into the yard when warm summer days and evenings make this desirable. If you build this five-tube set carefully, it will give excellent reception from stations 1,000 miles or more away.

The unusual cabinet that houses the chassis, speaker, and batteries of the powerful superheterodyne circuit, is nothing more than an inexpensive ten to fifteen-gallon wine barrel, which can be purchased from any mail-order house. Making the barrel resemble a beer keg requires simple, inexpensive treatment which will be described later...
