Nintendo 3DS

OK, so the above patently isn't a 3DS, but it did remind me that for better or worse I've owned nearly all Nintendos' handheld devices.
There was the original Gameboy, a Gameboy Color, the Gameboy Advance, a phat DS and a slim DS. I still have a space reserved on the list for a Gameboy Micro, but fear my eyesight isn't up to it. (And they still fetch quite a lot on eBay...)
So, after a cursory look at the 3DS in a store, I came away suitably impressed with the depth of field the screen lends to the action. It is true that you have to find (and keep) the 'sweet spot' for the stereoscopic effect to work, but even with the older systems gamers tend to hold their devices in a constant comfort zone anyway, so the 3DS shouldn't require too much effort. Pity about the battery life, which got better on older models as the tech matured. Maybe they're keeping that improvement for V2.
It seems likely, then, that I'll get myself a 3DS to keep the lineage of portable Nintendo systems going (I'm allowed to skip the DSi, OK?) and also for the inevitable Advance Wars 3DS. Happy days.

Rubik's Touch Cube
Even before you reach the product, the packaging is premium quality. One would expect nothing less as this is not a cheap toy, even if I did pick mine up at a bargain price at the local Costco. The packaging consists of two halves of quality boxwork, with the cube nestled in a neatly cut foam inner lining. Beneath this is the charger and cradle.
The cube itself is a well constructed item and despite its looks, each face consists of smooth, clear plastic. Actually, this plastic film picks up scuffs really easily - if you have an iPod you'll know what I mean. Also, as it's a sensitive electronic device, you'll need to handle it like any other electronic device - I wouldn't like to drop it or leave it buried at the bottom of the toy cupboard.
Now, in a normally lit environment, this is a light up cube. So far so good. But in moderately dim or even darkness, the cube is positively dazzling in intensity. The pictures don't do it justice, for the colours are rich and vibrant. Each facet has the ability to show one of the six Rubik Cube colours.
The red, green, orange and blue are achieved using discrete LEDs, the white with (I'm guessing) a combination of the red, green and blue LEDs, while yellow is the green and blue LEDs mixed. The effect is arresting, because of the brightness and evenness of the light. It's almost like holding a movie special effect, it's that good.
Each face carries it's own function, operated by the centre facet under which is a microswitch. These need to be double clicked to operate, I guess to avoid accidental operation. There's a power button, scramble and unscramble, volume (yes), a hint button and an undo button. The other cool aspect of this cube is that only the upper face is sensitive to touch at any time. So the device must have some sort of gyro aboard to determine this.
Stroking a slice in either axis will cause the cube to simulate a twist, complete with an unconvincing and repetitive sample of a real cube being twisted. The touch also responds to a diagonal 'rotate the top face' type gesture, but this is harder to successfully pull off, as it often sends another face spinning inadvertently. In the end, one resorts to one dimensional stroking to achieve the desired move.
The scramble option applies 20 random moves to the current state of the cube, enough to get any cube fiddler started. Unscramble appears to work by applying a minimum move type algorithm to the current state of the cube and a lot of the time it's not completely obvious what's going on other than a series of unrelated moves. More on this later.
The hint option makes the cube wink the next move you need to make towards completion, again using the same algorithm.
Undo is obvious, but is most useful for those mistaken moves, especially when handling the cube or getting the orientation set. Solving the cube with my own archaic level-by-level approach is doable, even easy with a bit of re-training of the muscle memory - the need to keep the operating face uppermost can be frustrating at times and the undo facility (which can undo a whole series of moves) is really useful.
Now let's look at what I'd call the missed opportunities of this device.
Remember that each facet is individually settable to one of the six colours. Forgetting that the designers could have used a tri-colour LED with a huge colour palette, there was still an opportunity to set the device to display an evolving set of patterns and colour shifts. Throw in a microphone, and the cube could pulse away randomly to music. In a half hearted attempt at this, it does at least scramble and unscramble itself whilst on charge, lending a nightclub glow to the immediate surroundings.
Taking that idea further, why not add an mp3 player? Not only would you have sound to light, but it could be it's own sound.
Moving on, there's the solving algorithm. Yes, it solves itself, but doesn't in any kind of meaningful way, to me at least. It would have been better to allow the option to solve via both methods - layer by layer is arguably easier to memorise as a novice as there are only half a dozen or so simple move combos you need to know to solve the cube from any position. If, like myself, you do solve by layers, then choose the hint option, the cube goes off on a tangent and messes up your work to that point.
Lastly, and kind of obviously, there's the battery. Disappointingly, for a puzzle that's meant to be studied for hours to get the hang of, a little over an hour of play is offered by the inbuilt NiCd cells before the thing, rather alarmingly, flashes red all over a few minutes before shutdown. And it takes ages to charge, easily several hours. I guess in the age of rapid charge Li Ion batteries, going back to NiCd is a bit of a culture shock.
And while the little charging cradle is neat - the cubes' little metal contacts making, er, contact when the device is propped on one corner - extended play would have been possible if a simple cable attachment had been designed in.
Despite these failings, the Touch Cube represents the ambitious attempt of a toy manufacturer jumping on the 'touch' revolution that has swept through the consumer electronics industry, and for that alone, they must get a little credit.
Shortcomings aside, I really like the Touch Cube. There are a zillion websites and mobile apps devoted to helping solve the original cube, but this is the first fully electronic cube that does what it says on the tin, in a really satisfying way.
Now, if only my 5x3x3 cube could solve itself...

App of the week
One such app is Holographium (App store link), whose purpose is not immediately apparent, even after a brief twiddle.
Presented with oversize controls, Holographium first prompts you to enter a phrase, then it asks you to choose one of several neon style colours. You then set a 'depth', then a duration.
The app then does a little calculating before flashing up a bizarre sequence of bright lines and rectangles.
At first, it makes no sense whatsoever, until you realise that the flashing imagery is not meant for human consumption - at least not initially.
No, the idea is startlingly simple. What Holographium wants you to do is move the flashing sequence in front of a camera with an open shutter.
The long exposure captures the animation as it move across the cameras field of view, spelling out the phrase you first keyed into the app.
The results are surprising.

Robonova steps up to the mark
My Robonova doesn't get out much these days. It's a time thing, see. If you're as time poor as me, you don't waste the precious little you do have on fiddling around with little humanoid robots.
Granted, like a good book, video game or movie, programming up your own 'droid can both be rewarding and a black hole for time. That's not a good analogy, really. Black holes make time stand still... anyhoo, you get the idea. It's an interesting hobby but vastly time consuming which is why I suppose I haven't written about it before.
Robonova, if you haven't met him before is a low-ish cost bipedal robot constructed out of servos, an aluminium frame and a micro-controller board to drive the servos.
Programming is done via a PC using the supplied Robo-Basic programming tool.
Now, out of the box, Robonova doesn't do very much, other than the stock moves supplied with the software. These moves are varied enough to give you an idea of what the little chap is capable of, but there are no sensors or AI out of the box like you might find in, for example, Robosapien.
But there's a wealth of information in the online robotics community if one cares to seek it out, and one of my future aims is to equip Robo with some sensors to facilitate some autonomy.
One task I was particularly keen to see was Robonova tackling some stairs. There are few videos on youtube showing this and those that are there are a little underwhelming. But credit is due to the roboteers involved for at least trying.

Come on, Windows
At the same time, I've been impressed by the time it takes Windows 7 to boot to the desktop, on fairly modest hardware. Good work, Microsoft. This in contrast to a Vista laptop at work which seems to take an eternity to settle down after switching on from cold.
So, in the interests of Science (and geekdom), I undertook to prove, once and for all, that we haven't really moved forward in the last ten years.

Art, cubed?

With a little sleight of hand, it's possible for me to make this cube look scrambled, yet solve it as normal for muchos kudos.

Struxx iPad Stand
Just got an iPad? Got an empty wallet? Wondering what to do with that Struxx robot you bought last year and left, forgotten, under the bed in the spare room?
Have no fear, mygadgetlife has the answer!*
Ok, I admit it, I had a... let's call it a nerdgasm, because let's face it - anyone with an iPad soon finds out that the device spends a lot of its time on its back when not being supported by hands or lap. Not much use for the fancy pants photo frame mode let alone the video playback mode.
Oh sure, you can prop up your iPad or couple it with Velcro, or you can just buy a stand. Have you seen the prices for some of the stands?
With that in mind, I sought a DIY solution and ended up discounting Lego, down to lack of confidence in its structural integrity. Fine for an iPod touch, but not for the iPad.
Then I remembered Struxx, the alternative construction toy.
What you'll need is shown below.


Next, form a triangle with vertices of 3 x size 14 spars, with 3 x 3-way ball joints. Angle the ball joints about 45 degrees so that the axis is pointed inwards.
Position the triangle so that the shortest side faces you. This is the front. Clip the two size 12 spars to the left and right ball joints, then clip a 8 spar to the back.

Position the triangle so that the point faces away from you. Clip a further two 12 spars to the left and right ball joints, then clip a 8 spar to the back corner.
Bring all the spars together and join them with a further 3 way ball joint.

Take the 75 degree angle joints and fit a single ball joint to each. Fit the angle joints to the inner left and right axis of the 3 way ball joints so that they poke out of the frame. These are what the iPad will rest on.

Take the 2 way ball joint and fit it to the axis of the top 3 way ball joint. To this fit the parts with the vinyl tips that were the robot's fingers. Angle the fingers slightly up and out to provide a suitable angle for you iPad.

You're just about ready, but first even up the frame a bit, make sure your angles are symmetrical and that the thing lies evenly on a flat surface.
There you have it, an iPad stand made out of Struxx.

my gadget holiday
Ok, so I kinda cut down on the gadgets for this year's Spring holiday to Wales, insofar as only packing my Sony HCR-5E camcorder, Panasonic Lumix G1 and a Nintendo DS.
Quite honestly, I don't know how we managed to get by that week.

On buying an iPad...

Nissan Leaf Test Drive
Nissan’s Leaf will be one of the first mass produced fully electric vehicles to be introduced to UK roads.
Last week, I had the privilege of taking one of the prototypes for a short test drive, as part of Nissan’s rather low key efforts to raise awareness of this new model.
With the Leaf, Nissan are attempting to bring to market a battery powered car in the shape of a regular family sized hatchback. And, to an extent, they’ve largely succeeded.
Of course, the usual caveats of EVs persist - limited range and (at the time of writing) poor recharging infrastructure.
However if, like me, you drive a 20-25 mile commute and have a garage within which to charge the vehicle, then the Leaf starts to become a serious proposition. Fuel is relatively cheap and is free of the duty levied on petrol and diesel. Being a zero emission vehicle, it attracts zero Vehicle Excise Duty - or road tax to you and me. There are fewer complicated oily bits to go wrong, so servicing should be cheaper.
As a result, the Leaf should be a cheap car to run. And, unlike the Tesla Roadster, the Leaf is approaching affordable, even if it is expensive for the size of car it is. Entry to the EV club was never going to be cheap for early adopters. The same was probably true for ICE automobiles until the Model T arrived.
Back to the Nissan event. The roadshow, if you could call it that, was held at 2 locations; the 02 Arena in London, and at the Centre for Life, Newcastle Upon Tyne. As the car is planned to be built at Nissan's Sunderland plant, Newcastle was the obvious choice for this demo.
Having driven down from Glasgow, and not knowing what to expect, we were a little underwhelmed to find a couple of small Nissan tents and a small exhibition trailer parked up in the courtyard that forms the campus of the Centre for Life.
That said, the Nissan staff were helpful and I quickly got signed onto the test drive list. The car was still being charged (unceremoniously left in a corner, near a power outlet), so we decided to come back after lunch.
Under one tent sat the 'static' Leaf showcar. Cordoned off, this was strictly hands off, because apparently they only have two - a left hand drive model and a right hand drive model. Present was one Nissan gentleman sporting white cotton gloves who was good enough to open the rear hatch and doors so that we great unwashed could get a better look at the interior.



Whilst the cream insides of the prototype might not be very family friendly, the blue tinged dash and controls looked very Star Trek. Whether this makes it to the production model remains to be seen.
Overall, we liked the look of the Leaf. The slightly bulbous look is deliberate - apparently it makes it look like an eco car - and I'd agree. And because it looks unique (as opposed to fitting the electric gubbins in, say, a Micra or Note), it's sure to leave it's eco mark wherever you leave it.
It was time for my test run. Turns out the test vehicle was actually a Nissan Versa, a production car available in the US, and thus a left hand drive. It had been modified to accommodate the electrics and drive train of what will be the production Leaf.

The first lap was with the Nissan test driver at the wheel. Let me tell you, this car can shift. And it does it silently.
Within the limits of the tiny track, the vehicles' performance was surprising to say the least.
My turn, now, to drive Nissan's only working model.
As I slid behind the wheel I found the controls were exactly like an automatic, and as my current car is a CVT equipped Nissan, I was right at home.
Still, I forgot to put my foot on the brake before engaging Drive, so nothing happened initially. (The CVT has a mechanical interlock - the gearshift won't move unless the the footbrake is depressed. Not so on the fly-by-wire Leaf.)
Underway, the car was surprisingly smooth. Nissan have obviously put a lot of work into making the drivetrain respond in a similar way to that of a petrol car and dipping the accelerator provided a pleasing burst of power.
The car does all this silently, of course. There is legislation being introduced to make EVs emit a sound to alert pedestrians of their presence. If not, I imagine the death toll in local supermarket car parks to be quite high.
So, test drive complete, the serious question of would I actually buy one quickly came up. I certainly fit the profile of a low-mileage commuter, and as we're a two car family, we always have a fossil fuel car for those long trips up and down the country. So yes, if the price is right, the Leaf seems a viable proposition.
Prices are to be announced in for the UK at the end of May 2010, so watch this space.

Struxx your stuff

Long, long ago, in a galaxy far, far away...
Today I'm looking at a really neat USB gizmo - the Sandisk Ultra II 4Gb SD card.
This is one of those SD cards that also slots into a USB port and presents itself like any other USB flash drive. If your laptop doesn't sport a SD slot, this little device is a godsend.
The 4Gb capacity means that it's only compatible with SDHC equipment such as my Acer Aspire One and digital photo frame.
However, flip open the cover, and the card can be used in any USB port. It mounts quickly on the Mac desktop, as well as Windows and Linux.
The double hinge mechanism looks flimsy, and it probably wouldn't stand up to rough handling, but it's well engineered and snaps shut with a satisfying click.
There's even a tiny activity light that remains invisible - I mean you really can't see where the LED is - when the card is unplugged from the USB port.
Transfer speeds are fast - what you would expect from this class of device.

Sandisk V-Mate
![]() |
The Sandisk V-Mate has been around for a couple of years now, but not only has it been discontinued, but no replacement device seems to exist that replicates the V-Mates' functionality.
