Rather Useful Seminar this Wednesday

IMGP0102.jpg

We will be doing our next Rather Useful Seminar on the 31st of October on the subject of publishing and legality. Rob Singhe from the University Knowledge Exchange and Rob Penrose from Andrew Jacksons Solicitors will be joining me, Rob Miles in the Robert Blackburn Building. (Can you see a pattern forming here?)

More Robs than you can shake a stick at will be talking about the nature of copyright, steps you can take to help make sure that what you thought of stays yours, and Rather Useful things to consider when you get together, form a little group (which is probably really a company) and start selling your wares via App Store or Marketplace.

The session will be at the usual time and place, 1:15 pm Wednesday 31st October in Lecture Theatre D in the Robert Blackburn Building. Teams from Three Thing Game who are thinking about selling what they have made are strongly advised to come along and take part.

Three Thing Game Judging

I got back into the university around 7:15 this morning. I always feel terribly guilty about not staying the night but I did try it once and it really did not end well. All of the teams still there (we had lost a few by now) had stuff that worked and things to play. All the teams had made massive amounts of progress overnight, particularly some of the ones from the first year who only started with XNA this week. I’m just so impressed by what you have done from that starting point. Kudos.

I formed the judges into four teams who went around scoring. We also had four camera operators who captured the presentations on video. I’ll be cutting these presentations into a show reel later. I’m going to use some of the game music from the competition as a soundtrack. There was some ace stuff.

Each team of judges then picked their top two entries, who went forward into the final rounds. These lucky folks got to present their solutions to the audience.

The survivors….

IMG_5324.jpg

This is ‘Three Game’O’Holics’, the first presenters, preparing to show off their game inspired by “Fighting, Desk, in a Dress”. This was an impressive take on the bouncy platform style game with a killer two player mode.

IMG_5338.jpg

This is ‘No Method, No Class’. I got emails from these guys a week ago asking if I could hook them up with a team. They picked a name much better than the one I suggested and then went on to make a top eight game from “Caffeine, Monkey, under attack”. The gameplay and sound-effects were top notch, as waves of monkeys came in for the kill. The Caffeine High mode was just excellent.

IMG_5352.jpg

If you want to get ahead, get a hat. Seemed to work for “Did you mean ‘Uncle Mikes Recursive Prolog Party?’” who had built a frantic space shooter game from “Fighting Toast Party”.  They had random levels, fantastic zooming viewpoints, swarms of enemies and a real “just one one more try” style of gameplay.

IMG_5361.jpg

Next up was ‘Sheerware Games’ showing off their Hyper Morph Windows Phone game, made from "Flying, Bombs, Tank". This had lashings of retro style, frantic shooting action and swarms of baddies to be despatched.

IMG_5370.jpg

The Honeybadger crew took Ninja, mountains, defence and crafted an atmospheric game with invaders storming your castle and you letting loose with ninja inspired weaponry to see them off. With sunset powered game progression and lovely artwork this was a smashing phone game.

IMG_5378.jpg

I reckon ‘Michael Jacksons Indian Takeaway’ is the best team name, although I have no idea what it really means. Their pun heavy title, “Spray of Duty Modern Warbear” was built on “Poptart, deodorant, teddy bear” and had a lone Teddy soldier using his deodorant to save off increasing numbers of invading poptarts of various flavours. With lovely shader powered plasma effects this looked superb.

IMG_5393.jpg

Its rare to see all of the Battle Brothers looking happy at the same time, but they certainly were pleased to make top eight. They had created an astonishing looking space warfare game from the starting point of “Pirate, ship, spoon”. This had great 3D graphics and a space opera plot involving spoon based pirate contraband . Of course.

IMG_5420.jpg

I could think of around twenty reasons why the game from ‘The Infamous Two Sirs’ would just not work. This had the most ambitious setup I've ever seen in a Three Thing Game. From the words “Goldfish, Plughole and Invasion” the team crafted a multi-player game experience involving a battle between Kinect controlled angler fish and Windows Phone powered goldfish. Everything worked. Wave your arms to move your angler fish and they dance around the phone screen. Marshal your goldfish on the phone and the player on the Kinect sees tasty goldfish coming into range....

As the judges left for their deliberations I thought to myself just how happy I was to not be in their shoes. But, after a lot of deliberation they managed to come up with a top three. Here they are in reverse order.

IMG_5424.jpg

Third place went to Battle Brothers. Well done folks. And to think that the textures were designed by someone who had never done them before this competition. Amazing.

IMG_5427.jpg

Honeybadger Productions clutching their Kinect sensor prizes. Well deserved and a game with great potential.

IMG_5432.jpg

Sheerware get the big prize. Richly deserved and hard earned. The sheer (sorry) attention to detail in the game and the way it looked Marketplace Ready was very impressive.

IMG_5435.jpg

Final prize of the day was the Peoples Choice Award. It was great to see the teams showing off their entries to each other. We got the scores off Survey Monkey and the voice of the people agreed with our judges, awarding Sheerware the prize.

Three Thing Game serves as a reminder to me why I love my job so much. The whole thing was just splendid. Special shout outs to Dave G. for fantastic lab support, Peter, David P, Martin, Simon, Mark, Kevin, Warren and Adam for all playing their parts in making this the best TTG we have ever had. Thanks also to Lee and David from Microsoft and Dean and Dominique from MonoGame for judging and giving the competition industry chops. And thanks to the students for turning up and being so gosh darned awesome. I hope you all got as much out of the occasion as I did. And we now all look forward to the next event…

Three Thing Game Day 1

IMG_5153.jpg

This is the traditional “before” shot. We’ll see how many people are still smiling when we get to “after”.

Three Thing Game is something of an institution at our institution. If you see what I mean. Every one is slightly different, but all of them are a bit bonkers, in the nicest possible way. Some things stay the same: Three Things to base the game on, Four students in a team, 24 hours overnight to deliver.. but we like to ring the odd change here and there. The last couple of events we’ve held auctions for the “things” that will be the basis of the games. Next time, who knows.

Anyhoo, we started today at 11:00 with “masses’o’hardware” turning up in the Fenner Lab, along with loads of “keen to go through the mill” students. There is always a frantic couple of hours while things settle down, network addresses are assigned and multiple monitors adjusted appropriately. This time we also had expertise in the form of Dave Brown and Lee Stott from Microsoft and Dean Ellis and Dominique Louis from the Monogame team. I did a quick XNA lecture early in the afternoon and then the Microsoft and Monogame team took centre stage to describe the opportunities coming over the horizon with Windows 8 and MonoGame.

Apparently last week Microsoft launched a new operating system. I was quite surprised to find this out, you’d have thought there would have been something about it in the papers…. All joking aside (ho ho) I’ve been using Windows 8 for a while now. I’ve found it stable, useful and remarkably like Windows 7. It has changed the way I work for the better. Programs are now launched in seconds with a few key presses, rather than a hunt through folders. I’ve used the Metro style user interface a bit, but I really want to see it on a platform it was built for (for example Surface).

Anyhoo, the rules of the game for Windows 8 applications have changed. Good News: You can now sell applications for Windows 8 just like you can for Windows Phone. Bad News: The Windows 8 Metro Style user interface does not encompass the XNA that we know and love. Better News: You can use MonoGame, to create XNA applications that are Windows 8 Store compliant. Even Better News: MonoGame versions of your program can also be ported onto Android, iPhone, PS Vita and even the Raspberry Pi (coming soon).

Lee from Microsoft set out how Windows 8 can make your programs more interesting and marketable and then Dean and Dominique showed how easy it is to port an existing XNA game to the MonoGame framework. If you are an XNA developer you must, must, must, be looking at MonoGame. I reckon it is the future of XNA, and I’m jolly pleased to see it there, in such good health.

Once we’d had the presentations the development got going in earnest. I of course staggered around with the big camera and took a whole bunch of pictures which have found their way on to Flickr if you want to see all of them.

These guys are “Haribo Hardened”….

That should be enough keyboards...

These guys are so reading the right books...

None of these smiles are forced. For sure.

We ordered 45 pizzas. And they all got eaten.

I staggered home around 10:45 leaving Martin and Simon to run the night shift. Judging tomorrow morning. Looking forward to it.

Writin’ Skilz R Important

IMG_0449-Edit.jpg

If I had one piece of advice for a Computer Science student I think it would be nothing to do with programming. Or even computers. It would simply be “Learn to write well”. This doesn’t mean I necessarily want to see short stories, or poems (although send them through if you like), it just means that the art of putting words our there that make sense is something you should work at.

In my experience the only way to get good at writing is to write a lot. Then write some more. Blogs are great for this, as are diaries. And Final Year Projects. Just set yourself the task of knocking out a few words a day and putting them somewhere where others can find and comment on them. Try writing in other styles, from the dry “It can be shown that” kind of report style to anything else you like, including murder mystery if you fancy having a go. And get used to revising your text after you have read it. Just because there are no wavy red lines on the page doesn’t mean it actually makes sense. Watch for repeated phrases that repeat themselves repeatedly. Try to find alternatives to make the text sound better.  A good tip is to read out loud what you have just written. Anything that is not quite right will really sound  that way.

Another tip is to read stuff by people who can write well. The BBC news site is pretty good for this, along with newspaper sites like the Times and the Guardian.

I’m not saying that Computer Scientists are now doing an English degree. What I’m really saying is that if you can express yourself in written words, this will pay off big time when you go for jobs.

So Many Things. So Little Time.

What 20,000 pounds actually looks like. Of course you can't spend it in the shops...

Teams and their Two Things

We had our Thing Auction today. Last year we just managed to get through all the lots in the time that we had. This year we had more teams and just didn't make it. There was a time when I thought that we would get everything done, then a couple of mammoth bidding wars put us a bit behind schedule.

Never mind. We plan to run the "Third Thing Auction" just before the Rather Useful Seminar on Wednesday. That's at 1:15 pm in LTD on the Third Floor of the Robert Blackburn Building. The lecture is all about preparing for Three Thing Game, so it seems rather appropriate.

If any team really can't wait until then to get their hands on a thing, they can contact me and I'll dig one out for them.

It was fun though. The sound the crowd made when the thing "Keyboard cat" came out was wonderful.

Sunday Printing

IMG_5129.jpg

I’m getting the hang of 3D printing now. I started off thinking that I would be using it to print cases for gadgets. I am doing that, but now I’m just printing out things that I find pleasing. Like the “Heart Gears” above from Thingiverse. I’ve been busy today writing quiz questions and auction stuff for Three Thing Game and in the background Una the Ultimaker has been turning out the parts above. It is a design that we saw at the exhibition yesterday and I really like it.

I’m not completely happy with the results (that will never happen) but on the whole I think it works well. The gears turn and the object turns into and out of a heart shape. I need to adjust the flow and layers slightly to get rid the gaps in the surfaces above.

3D Print Show

DSCF8932.jpg

The wristband of power. And a Lego watch

Another reason to go to London, apart from the Augmented Reality event yesterday, was to drop in on the 3D Printshow that was taking place in London this weekend. Ultimaker, the company that made my 3D printer, were there and I wanted to drop by and see how they were doing. I also wanted to see what was going on in this area. The answer is rather a lot. We arrived before the show opened, but there was already quite a queue snaking around the courtyard waiting to get in. Fortunately we weren’t waiting long and soon we were inside marvelling at the way this technology is moving forward. And boy, is it moving. I counted five 3D printers I’d never seen before, all printing away merrily in front of throngs of fascinated folks. Autodesk were there too, along with lots of other companies, some I’d heard of, some not.

DSCF8857.jpg

The folks at Sculpteo will take your designs and make them. You can even design your artefacts on their web page.

DSCF8858.jpg

They can even print in colour, and the quality is lovely.

DSCF8867.jpg

There were some lovely examples of printing

DSCF8878.jpg

This is a great piece of art. The heights of the keys show the popularity of the web sites behind them.

DSCF8881.jpg

This was a very clever piece of 3D art. The cylindrical mirror in the middle shows a perfect image of a hand, reflecting the seriously distorted sculpture.

DSCF8920.jpg

They had a band, and of course all their instruments had been printed…DSCF8894.jpg

At the Ultimaker stand they had a seriously impressive dual extruder printer which had turned out some incredible prints.DSCF8888.jpg  

One major bonus was these folks being at the show. Formlabs might just have the future of 3D printing in their hands. They’ve built a 3D printer that uses an optical technology and special syrup that solidifies under UV light. The resolution is streets ahead of anything comparable at the price. Only snag I can see is that the raw material is a bit pricey, at 130 dollars a litre, but with a bit of luck this will drop over time. Some of the things they had printed were astonishingly good and because there is no messing around with hot and sticky plastic, their printer has a good chance of making it as an appliance.

There were lots of people selling ready made printers and claiming that they have a device for the mass market. I’m not convinced of this. I’d love to be proved wrong, but for now I still see it as a tinkerer’s toy. Ultimaker sell their machines as kits and I think that this is actually quite an honest thing to do. Once you have built the machine you end up with a pretty solid understanding of how it works and how to fix it when it goes wrong. And I reckon all the current crop of printers will go wrong I’m afraid. In a few years time, when the technology has settled down, maybe we will see it in the home, From the interest that I saw at the show, this is just a matter of time.

Creating Augmented Reality in Education

DSCF8850-Edit.jpg

Audience shot. Thanks for being a super bunch.

I was up bright and early today. Well, early anyway. The taxi was picking me up at 5:45 to get me to the station for a train ride to London. I was giving a session at the “Creating Augmented Reality in Education” event. By 5:55 the taxi had still not turned up and a panic phone call to the company revealed that the driver was out there in the mist looking for my house. So, I told him where we could meet up and then, pausing only to step in a deep puddle, fill my shoes with muddy water and say a rude word loudly for the whole of the street to wake up to, I headed for the cab.

We made it to the train with minutes to spare and I got there just in time for the first session. There was a great range of stuff, from descriptions of work in Health Training to eye popping demos of flying dragons and Mars Rovers to thought provoking discussion of just how this stuff is going to change the way we interact with computers and also the world around us. The consensus would seem to be that the stuff is coming, it will change our lives, but we don’t quite know how yet. Perhaps our kids will tell us. The sessions were videoed and should be available at some point. Well worth a look.

I did a session on how the Kinect sensor works, and how the data it produces can be used to get interesting behaviours and applications. My finest moment was asking the chap at the back why he was waving a piece of card with the number “3” printed on it. “Because you have 3 minutes left” was the rather sensible reply.

Anyhoo, all the demos worked, and my shoes and socks dried up fine. You can find the slide deck for the presentation here. You can find a more detailed presentation with code descriptions, along with the demo code, here.

3D Printing at the Rather Useful Seminar

IMG_5118.jpg

Una getting star billing

Some time back I rather rashly promised to bring my 3D printer in for a Rather Useful Seminar. Well, today was that day. The weather was horrible. Just the kind of torrential downpour in which you want to carry your high precision printing device. Partly made of wood.

Anyhoo, thanks to help from Adam, a blue Ikea carrier bag (just about a perfect fit) and a big bin liner I managed to get Una the Ultimaker into the lecture theatre and so I started the seminar. As usual I’d prepared a slide deck and so I stated working through the background to 3D printing, talking about the different technologies and how they worked. Then I glanced at the audience. Nobody was looking at me. They were all staring transfixed at Una, who was sitting on the bench doing nothing.

So, that was that. It was straight over to the PC, draw something in Sketchup (a really great, free program), export it to an STL file, slice it with Cura and then get Una printing.

People love watching 3D printers do their stuff. In a world where pretty much everything has been made “Ho Hum” by technology there is something rather magical about a device that makes something appear from nothing. Una behaved herself very well. Once she’d printed the silly design I’d made in Sketchup we went on to print a tiny rocket, and she handled that with aplomb. Then it was back into the bag for the trip home. I’ve just unpacked her and she seems none the worse for the trip out.

I really like this device. It is well thought out and works a treat. And everyone seemed to really enjoy seeing her in action. I’ve put my slides on the Rather Useful Seminars site, but you would probably learn more by just searching YouTube for videos of Ultimakers…

Phone Home

image

A student brought me a mobile phone which they found in the lecture today. It was an Android device with a lock screen. I couldn’t do much with it, so I just took it home and waited for it to ring. The first few seconds of the call were interesting as I was a bit worried that the caller might think they were talking to a phone thief and that outside a SWAT team were waiting to burst through the door, spray the room with bullets and prise the phone from my dead and broken fingers.

Perhaps I’ve been watching too much Person of Interest.

Anyhoo, names were exchanged and with a bit of luck they’ll get their phone back tomorrow. One way we could have avoided this would be if the owner had put contact details on their lock screen, so that I would have known who to call. This is not hard to do but it is fiddly, because you have to edit the background image and add the text, and if you change the background picture you have to do it all again.

Of course if it had been a Windows Phone they could have just installed the Lost Phone app on their device, which does all the hard work for them.

This is also a very interesting application because the author, Scott Hanselman, wrote version 1.0 in six hours and also produced a really good blog post about the process and described some good practice when you are writing Windows Phone applications.

Buying Hardware

IMGP0100.jpg

Building the PiArcade table is turning out to be quite fun. It is also giving me an excuse to go out and buy some more tools. Yesterday we went down to ToolStation for some bits and bobs as James had mentioned that their prices are very good.

They are. Their stuff is a lot cheaper than places like B and Q (does anyone actually know what the B and the Q stand for?). The only real problem is that you can’t just wander down their aisles looking at stuff to buy, instead you have to dig out all the part numbers and then write them down. But if you are after some no frills hardware they are worth a look.

PiArcade Table Progress and Compromise

DSCF8849.jpg

Did some more work on the PiArcade table today. I’ve got the right hand joystick all fitted and working, along with the buttons. I’ve also made the holes that will allow the monitor cable to be fitted in the back and I’ve made my first major compromise. You can see it in the form of the four shiny screws that hold the joystick in place above.

I was going to implement a strict “no screws on the top” policy because I reckoned it would look a lot cleaner. But it would have meant a fair bit of extra fiddling, and might have resulted in a joystick that was not as firmly anchored as the one above. So I compromised. I can always paint the screws black, or put a bezel over the top, or just decide not to worry about it.

The only snag that I’ve hit today is that the wires to the second joystick aren’t quite long enough to reach across the table, but a few minutes with a terminal block or two should sort this out.

Campus Open Day (again)

DSCF8839-Edit.jpg 

We had our second autumn open day today. The weather started a bit grey, but it soon brightened up a bit and by the time I left the campus the place was looking very shiny. Two great audiences, thanks to everyone for coming to see us. I mentioned some links in my talk. Here they are if you didn’t get to note them down at the time.

New Embedded Stuff

There are quite a few new embedded toys that I’ve discovered just recently. Here are three.

image

First up is the DAGU racer. This is a neat little Bluetooth controlled racing car. They’ve got it on discount at RoboSavvy at the moment. It comes with an Android app that you can use to control it, but they also expose the Bluetooth command set so that you can control it from anything, including Gadgeteer I reckon. It is powered by a tiny lithium ion battery and even comes with a set of stickers you can use to customise the racer. And for under twenty quid it was very tempting. So I got one.

image

I got all excited when I first found out about the Electric Imp. This is a wireless embedded device that fits into an SD card socket. You can’t actually use it as a memory card but you can use it to control a connected net appliance. And you can get it for around twenty quid. My excitement dissipated quite a lot though when I discovered that every device is bound to the imp cloud service which is where it registers its data and where messages come from.

I’ve bought these kinds of devices before, my Chumby and Nabaztag rabbit worked in a similar way. The idea of the company behind them is usually that they don’t make much money on the devices themselves, but build a subscription model which lets them pay for the infrastructure by getting cash somehow from the users of each device. Snag is, if that doesn’t work and the company goes bust you are left with a paperweight.The folks behind the imp seem quite confident that they can make it work, and the service is free at the moment. But they are talking about $50 subscriptions for business users and stuff like that, so I think I’ll pass on this, amazing as it is.

image

Now this I really do like. It brings you the best of the .NET Micro Framework, Arduino and Gadgeteer in a single board that costs less than thirty quid. You can feed it five volts and it just works. You’ve got an Arduino shield, three Gadgeteer ports, SD card, USB client and host and a space to put an Xbee or WiFi receiver. I’ve been looking at very simple devices that I’d like to make using the Gadgeteer and wanting a cheap, simple board that just gets things done. The FEZ Cerbuino Bee seems to fit that bill perfectly. For less than the price of a video game you get a device you can program with .NET, connect lots of Gadgeteer devices to and put onto WiFi at a bearable cost.

If you are learning C# and want to dip your toes into embedded development I can’t think of a better start. Lovely.

No Gas

IMGP0082.jpg

At least we have electricity

Came home tonight to no gas. Which in my case (gas central heating) means cold house. A water leak had somehow got into the gas supply and as a result it had shut down.  They are having to dig up the road to find out where the problem is and we’ve turned on the PS3 and are watching Fringe to try and warm up.

Fringe is absolutely top notch telly. Where else do you get lines of dialogue like “So why do you think shape shifting soldiers from a parallel universe are stealing frozen heads?”. Why indeed?

Pi Arcade Joystick Interfacing

IMGP0091.jpg

I’m trying to get the entire department working on my Raspberry Pi powered gaming table. After sterling work by Peter on the cabinet, today it was the turn of James to lend a hand with the button and joystick interfacing. The kit that I’ve bought comes with a USB to button interface (you can see it at the bottom left of the above picture). all we had to do was wire the right buttons and switches to the pins on the interface, connect it to the Raspberry Pi and then remap the controls in the software to use the right switches. And the amazing thing is that we did just that.

By the end of the day we had an arcade game running and the only problem left to solve is getting the sound output to work. At the moment the Pi is putting the sound down the HDMI cable. We need to change this over to the 3.5mm jack socket and then I can get some amplified speakers connected.  At this rate it should be finished well before Christmas….
