When the iPad was first announced, I really didn’t see the point. Like a lot of people, I was hoping for a tablet-style version of a MacBook; surely it wouldn’t be too hard to take a MacBook Air, put a touchscreen where the keyboard is, and sell that? But Apple had other ideas; iPhones have been so successful largely because they are so easy to use, so they decided to build on that instead.

So is the iPad simply “a large iPod touch”? After my first day of use, I’ve got to say that yes, it is-and yet, it isn’t… It’s all the good stuff we’re used to (apps, touchscreen, browser, email, ease of use) plus some extra good stuff (speed, larger screen area, better keyboard, increased battery life). There is a small amount of added bad stuff: it’s a bit heavier than I’d like; I can’t hold it in one hand for as long as I can hold my E-reader, for example. It only has one speaker, despite it being billed as an ideal way to watch movies on the go. And the dock connector is in the wrong place for using the iPad as a video player or photo frame- would it have killed them to put a second connector on the side so it could be docked in landscape mode? The last bad thing I can think of is the price- I know first versions of products do tend to be more pricey, so hopefully we’ll see the price drop by £100-£150 or so in the future.

All that aside, though, I’m pleasantly surprised by the iPad. It’s a fantastic way of surfing the web, doing email and updating a blog whilst on the sofa. I’m not convinced that it will make a good ereader- I’ve tried some sample books and as I expected, the screen is nowhere as good as the one on my Sony ereader. Add in the increase in size and weight and the dedicated ereaders have nothing to worry about.

I’ll post another blog once I’ve had some more use out of it, but so far, I’m impressed. And yes, this was written on the iPad, using the Wordpress app.

My local RC club, DMS Racing, has recently started regular heats for micro racers. Since I have been well and truly bitten by the RC racing bug, I caved in and got myself something to race. In this post I’ll be having a quick look at the Carisma GT14 1/14 scale touring car, and I’ll also be posting about the Team Associated SC18 short course truck later.

First, a bit of video. When I got my Gt14, there wasn’t much info about it, so I figured I might as well do one of those “unboxing” videos that seem to be quite popular these days…

Having spent a bit more time with it, I must say I’m really looking forward to racing this for the first time. I’m very impressed with the attention to detail of this car, especially considering it could so easily be mistaken for a toy. The shell alone is a work of art – I’ll try my best not to scratch it up too badly on its first outing, but no promises! Obviously a realistic shell isn’t super important on a car that’s going to get raced and see some hard times, but it looks like they’ve already thought of that – the wing is held in place by four body clips, and I was very surprised (and glad!) to discover that the wing mirrors can be easily removed. I had thought that the first thing to go would be the mirrors, because although they’re a lovely scale touch, they do look extremely vulnerable. However, undo a screw, and each mirror comes right off. Speaking of the shell, each shell is available as an option (see the list of Carisma GT14 bodyshells here), and there’s also a clear Mazda 6 shell for custom paint jobs.

Moving on to the chassis, it’s quite impressive how they’ve shrunk a regular 1/10 touring car down to 1/14 size. Everything you’d expect to see is right there – adjustable shocks, proper diffs, a servo saver, adjustable geometry, slipper  - there’s even mountings for anti roll bars. There are a number of upgrades available (and there’s also a “pro” spec chassis-only version, the GT14 Pro V-One) so some of the components are basic – the shocks are adjusted using clip-on rings, unlike the threaded body “Pro” shocks; it doesn’t have the aluminium adjustable turnbuckles, settling for threaded rods; the chassis isn’t carbon fibre; the tyres are scale treaded instead of slicks or foam; and the diffs are geared instead of ball. However, for a nice, easy, out-of-the-box racer, you’ve got everything you need to keep you occupied for a while.

The motor is a bog standard 370-size brushed unit, however even this has a couple of nice touches. First off, there’s a clip-on heatsink (which I’ll be swapping onto my SC18 next time I race it!), and secondly, replacement brushes are one of the option parts! I imagine a lot of racers will be wanting to swap a brushless system in, but it’s good to know that if you stick with the standard motor you’ll be able to maintain it. I wouldn’t be surprised if some clubs ran a controlled class of this car, to keep costs down and make it easier for people on a limited budget to get involved.

Even the radio is quite decent. I’ve opted for a 2.4GHz model – I really can’t be doing with crystals and frequency clashes and so on, so for the extra £20 or so, it’s worth going for.  In fact, it’s really the only one that makes sense – apparently the 27MHz models have a combined ESC and receiver, so if you ever did want to go to 2.4GHz you’d need to replace both the ESC and the receiver, which would cost you more than the extra for the 2.4GHz model in the first place. Just a 2.4GHz receiver would be at least £35, so it makes no sense at all to go for an FM model. Anyway, the radio gear is not bad at all – the transmitter takes four AA batteries (supplied!) unlike the SC18’s demand for eight, and as well as the usal throttle and steering trim, you’ve got end point adjustment AND a dual rate knob. Not bad for a kit radio. The only downside is that even though it’s a 2.4GHz system, the receiver’s aerial is just as long as any FM aerial – at least 30cm or so. Fortunately it doesn’t seem to mind being coiled up inside the shell, so I’ll be racing it like that.

Anyway, that’s my first impressions – I’ll post an update once I’ve given it a run around the track!

Little and large

Little and large...

I’m thoroughly enjoying my Traxxas E-Revo. It’s stupid amounts of fun. The only slight problem is that it’s too big for me to run at home – the garden just isn’t big enough for a 1/8 scale RC monster truck. Especially not one that’s been upgraded to brushless – I pull the trigger and straight away, it’s in the geraniums.

Thankfully (for my wife’s herbacious borders) Traxxas recently released a 1/16 scale E-Revo, the E-Revo VXL, which is exactly half the size of the original. Not only that, but it has a water-resistant brushless motor and ESC. So, does half the size mean half the fun?

Switch your iPhone to another network

You're not tied to O2

My iPhone 3G contract with O2 ran out a few weeks ago, and while I wait for the next model to be announced, I thought I’d see if the other networks were any better. Now that O2 is no longer the only network for iPhone, there’s the opportunity to switch provider – O2 has been ok, but sometimes texts are delayed, calls don’t reach me, and 3G performance has not been great.

Fortunately, O2 have made it quite easy for iPhone owners to switch provider, so anyone can give it a try. And, since I’m not actually ready to switch provider just yet, I’ve got a couple of tips if you’re thinking of staying with O2 after your contract has expired.

Read on to find out how you can set up your iPhone with another provider, or switch your O2 contract to something cheaper. continue reading…

You’d think it would be easy to spot when you’re about to send a very inappropriately-worded text message, wouldn’t you? For me, apparently not…

It all started a while back when I finally got around to getting in touch with a very good friend of mine, who I had been a bit lax about staying in touch with recently. She gave me the fantastic news that she was getting married later in the year, and I suggested we meet up to celebrate (and so I could vet the lucky chap). Unfortunately, family issues distracted me and I didn’t follow up. Then yesterday I suddenly remembered that I hadn’t spoken to her for a few weeks, so I resolved to get in touch in the next couple of days.

That brings us to today – a cold Monday morning. The day starts badly – the Jubilee line is down, and as a result the Bakerloo line is overcrowded so they’re not letting people onto the platforms at Baker Street. I eventually have to go via Euston and end up getting to work about half an hour later than normal. As I rush in to the office, I get a text from my friend telling me the date of the wedding – and whilst I am in mid-reply, I walk onto my floor to see my colleague on hands and knees under my desk, power cables everywhere, and not looking happy. Must be another power failure or something – a bad start to the morning looks to be getting worse, so I hurriedly finish my text, basically saying I’ll email her shortly, and get on the floor to help out.

Ten minutes later everything is sorted, and I’m waiting for my laptop to boot up – I’m still a little distracted by the power cables, though. My phone rings.

Me: “Hiya, what’s up?”
Colleague: “Morning. Can you make that design change you suggested?”
Me: “Yeah, sure. I’ll do it when I’m turned on.”
Colleague: “<snigger>”
Me: “What?”
Colleague: “<snigger> What’d you just say?”
Me: “I said I’ll do it when I’m turned on. What’s so… awww, crap, I meant when my LAPTOP is turned…” <pause> <suddenly realising why I’d just automatically used that phrase> “AWWWW, CRAP! NUTS! NOOOO! NUTS! NONONONO NO!” <buries head in hands>

Why had that phrase sprung so readily to mind? Because this is what I’d sent to my soon-to-be-married friend:

“Yay, was just thinking about you last night, will mail you when I’m turned on”

It turns out that no matter how hard you wish for it, time will not rewind to before you hit the ’send’ button on an unfortunately-phrased SMS. Believe me, I tried…

I’ve had a chance to try out the Ear Force X41 wireless 5.1 headphones for a while now, so here’s what I think of them.

Surround sound is good. I like my surround sound system. My neighbours, on the other hand, aren’t so fond of it! So, to be neighbourly, I’ve been on the lookout for a decent set of wireless surround sound headphones, and at long last I think I’ve found the ideal solution.

Professor Layton and Pandora's Box

Professor Layton and Pandora's Box

Today’s a great day for Nintendo DS owners – a new Professor Layton game is out! Professor Layton and Pandora’s Box gives us another dose of the charming gameplay found in the first game, Professor Layton and The Curious Village.

The games basically involve you solving lots of puzzles whilst investigating a mystery. The actual story itself is pretty much irrelevant, and only serves to move you from puzzle to puzzle, but it’s a nice change to all the frantic action games that seem to make up most of the charts these days! In addition to the puzzles, there are also places to explore and items to collect along the way. The game is presented in a hand-drawn cartoon style, with voice actors playing the various characters, and the occasional animation clip for key scenes.

The puzzles range from the amazingly easy to the mildly difficult, and if you do get stuck there are hints to nudge you in the right direction. As with many Nintendo games, it’s clearly aimed at entertaining all ages. Younger players will still be able to solve many of the puzzles on their own, with or without hints, and older players will get just as much satisfaction from getting them right first time, or without any assistance at all. We had great fun playing three or four puzzles a night for a few weeks, although some of the trickier puzzles can end up in tussles over control of the stylus for “just one more go, I think I’ve got it this time – oh, no, I haven’t, just one more go”…

Amazon currently have the best prices – the first game (Professor Layton and The Curious Village) is around £18, and the new one (Professor Layton and Pandora’s Box) is around £28 – everyone else seems to be doing it for £30+ as of 25 Sept 09 – even Play, which was a surprise.

I thoroughly recommend both these games! Buy them! NOW!

There’s been a steady increase in interest around Ebook readers in the UK recently, and since I’ve switched back to reading instead of watching video on the tube to and from work (no, really, I must be growing up or something), I decided it was time to have a proper look and see what’s what.
