Raspberry Pi with a dollop of Lego

Pimp my Pi!

Lego

When it comes to making a case for your Raspberry Pi, Lego is really the only way to go. I didn’t have the heart to use my daughters’ shiny, girly pink Lego bricks for this, so we dug out my husband’s Lego from the cellar.

Vintage Lego

We worked out that some of this Lego is FIFTY YEARS OLD, inherited from an older cousin! Some of it’s a bit discoloured but on the whole it’s in great condition and felt somehow “right” for styling a Raspberry Pi.

This is what we came up with. The yellow fruit Polo thing is decorative but also structural.

Note the subtle modification to make it WiFi. Saves clogging up another USB port.

It got quite a few retweets on Twitter but there was some disappointing scepticism….

Centre for Computing History

So I started thinking about the combination of 50 year old Lego and brand new Raspberry Pi computing technology. What was happening in computing fifty years ago when this Lego was being forged in a Danish furnace?

An internet search brought me to the Centre for Computing History. It will be opening to the public in July 2013 in Cambridge but in the meantime its website is full of useful information such as a Computing History Timeline. Cool!

So let’s choose 1963…

I hope you’ll explore those links.

And it’s worth pointing out that you’d have needed far more Lego bricks to encase your computer back then….

My seven year old daughter’s first ever CoderDojo – at Manchester’s MadLab

“I just want to make a horse riding game!”

Just being in Manchester’s Northern Quarter is exciting. It’s very different from our little village!

That was Isobel’s plan for her first CoderDojo on 7th April 2013. I just wanted her to enjoy it and didn’t expect her to learn much on her first visit. I thought she’d just be testing the waters, having a look around, seeing if there were other girls her age there (very important when you’re seven).

So we decided to make a day of it. The CoderDojo is at the MadLab, right in the heart of Manchester’s Northern Quarter so just wandering around was a bit of an adventure.

Making Scratch Friends

It was busy and chaotic at the beginning in the best way possible. Isobel hooked up with a couple of other girls her age who are old hands at CoderDojo. They joined a Scratch group  aimed at the younger children. It was led by the fabulous, inspiring, endlessly patient DJ Adams who came up with an idea to write a program that would take the monotony out of Times Tables. They all thought this was a much-needed tool!

Need to fuel up before CoderDojo. Home Sweet Home almost opposite MadLab is my perfect choice.

The perfect preparation for a first CoderDojo. Home Sweet Home cafe is almost opposite MadLab (it’s the one with the green shutters) and the milkshakes are delicious!

With a mix of gentle questioning, allowing the older children to use their knowledge and experience, he took the group through the process step by step. Isobel’s new friends helped her out a couple of times which made it all the more sociable. It was just lovely to see such young children completely engrossed in a problem-solving task together.

New Challenges

Wouldn’t it be great if they could do stuff like this in ICT classes in school? I’d love to see teachers being able to pick up something from elsewhere in the curriculum (times tables is a good example) and then exploring it in a computer class.

Even better, after DJ had finished, the girls started chatting about how they could make the times tables program even better! Could they get the monkey to move its mouth? Could he explode at the end?! DJ set Isobel a challenge – could she get the monkey to put its arms out when the answer was even and down when the answer was odd. That got her thinking….

The Banana Piano

So much interesting stuff going on all over the CoderDojo! Isobel’s new friends dragged her over to see Steven Flower – the organiser of under-18 events at MadLab – make a piano out of bananas.


Yeeaaah, the banana piano is good, but Isobel just wanted to get back to her program so she could work on getting the monkey to react to odd and even numbers. She’s still not sure how to do it but knows she has to make another “costume” for the monkey sprite so gets to work on that.

Scratch monkey

Eureka!

Another wonderfully generous, patient mentor talks Isobel through the modulo operator. Suddenly, she sees a way of solving the challenge. It’s exciting for both of us – but it’s time to leave.


Dinner vs debugging

Some things are more important than dinner….

She wants to work on it on the train home. I draw the line!

But as soon as we get home…..

Nothing was more important to Isobel than fixing that program! She still needed guidance to get it to work and it took a lot of trial and error. But she got there in the end.
TimesTables in Scratch

We did NOT make a horse riding game!

For me, that was the biggest achievement. I saw a different side to my daughter. Who’d have thought she could be so passionate about something which doesn’t involve writing a story (about ponies, usually)?

I met lots of familiar faces at CoderDojo, met new people whom I hope to see again and I came away with lots of new ideas for our CodeClub. Sadly, we won’t be able to go to the next CoderDojo because it clashes with the Mellor March – the big annual charity event in our village. But we will be back!

And finally, I’d like to say thank you to all the wonderful mentors who make CoderDojo such a fantastic experience for children and their parents. I’m very grateful.

Mobile Reporting exercise using Soundcloud, smartphones and Storify

Digital Journalism is fun in the sunshine!

Digital Journalism is fun in the sunshine!

This is a class project I worked on with first year Journalism undergraduates at Salford University, MediaCityUK. It was part of their Digital Journalism module. There are four groups each with about 15-20 students. My aim was to get them to explore audio recording on their smartphones/iPads and to create digital stories using curation techniques.

Choosing a storyBEhgHIXCEAAhATP.jpg-large

Every week, students complain about the bus service which goes from the main university campus to our MediaCityUK building. It’s free to students on the stretch between the two campuses but it’s unreliable, they tell me. It’s a frequent reason they give me for being late to class! So let’s turn a negative into a positive and use this as the basis for our mobile reporting class.

The Tools

Most students in the class have smartphones or iPads – certainly enough to make this exercise work. Not many have done any serious audio work with them though so there are plenty of learning opportunities here. I’m indebted to Mark Settle at the BBC College of Journalism who specialises in smartphone reporting. His video tutorial on recording audio came out the day after this exercise so it was pretty timely! But my favourite tip came from Nick Garnett, a BBC 5Live reporter. He’s a bit of a pioneer when it comes to iPhone reporting and has pretty much ditched other recording equipment. His blog about his experiments and discoveries is incredibly useful. I’ve always been worried about using the internal mic on the iPhone for serious audio recording because it’s so prone to wind noise but I’m yet to find the perfect external mic solution. His tip is simple –  an ordinary windshield on the microphone end of the iPhone!

Windshield on iPhoneSee my twitter conversation with him about this. So I bought one the day before my first session with the students so I could get them to experiment for me. £4.49 in Maplins!

Most students already use Soundcloud for sharing and searching music so this seemed like a good place to start. I set up an account for all our students to use and gave them a quick demo in class, including the simple “top and tail” editing facility. I told them to save their audio as private. Not everybody had devices or 3G but so long as 5 or 6 in the class had it, we were OK. I also showed them Voddio in case some of them were feeling ambitious and wanted to do some proper editing and mixing on the go. Nobody did but that’s probably because you need to pay £6.99 to get the sharing/sending facility on Voddio.

The final element was Storify. I love Storify and was really keen to introduce it to my students! Again, I set up an account for the class to use and gave a quick demo. Storify is not perfect and sometimes it doesn’t hook up to Twitter as it should. We had some issues with it in the first two sessions but found a workaround. It was fine the following day with the other two groups. I know some people have given up with Storify completely because of its problems. I’m sticking with it because, when it does all work, it opens up so many creative opportunities for storytelling and engaging. Great teaching tool too.

The Task

I asked three students in each group to volunteer to man our digital newsroom (an ordinary classroom with PCs). There was no shortage of volunteers, I’m pleased to report! Everybody else teamed up into reporting teams – mostly pairs but some slightly bigger groups. We decided which aspects of the story we were interested in and what kind of audio material we wanted.

The newsroom team then took charge of deploying their reporters with additional instructions to take photos and tweet information.

Once the reporters were despatched, I briefed the newsroom team in more detail. I gave more instruction on Storify but, to be honest, they didn’t really need it. We talked about what makes good curation. Again, credit here to Mu Lin at Georgian Court University, New Jersey for putting together some guidelines. Basically, don’t drag and dump; provide context and background; have a structure; be selective.

One student specifically looked after the Soundcloud material once that started coming through. They listened through to all the material and made public the ones which were good enough for our story. They then alerted the Storify editor to the availability of the material.

I also wanted the newsroom team to use social media to engage the broader student community which also relies on this bus service. Could they get people outside this exercise to contribute to the debate? They came up with the hashtag #50busprobs.

Once the exercise was over and everybody was back in the classroom, the newsroom team briefed the reporters on what they’d been doing. we published the stories and explained the “notify” option on Storify.

I encouraged students to embed/export the Storify to their personal blogs and add a paragraph about their own contribution and analysis of the task. This was not assessed.

The Outcome

You can see an example of the stories created by students here just to give you a flavour of what they were able to do in the limited time (about 75 minutes).

The newsroom team worked really hard to engage with the broader community with some success. Maybe we should have started doing this in the week before the exercise to build momentum.

Working with Storify was great. It’s a really intuitive tool for building digital stories quickly. The students picked up the concept of curation v drag ‘n’ dump really well. They worked together to find relevant background context and structure whilst they waited for the audio material to come in from the field.BEhd7oUCcAAha7E.jpg-large

The students assigned to editing the Soundcloud material quickly worked out what kind of material would work best in a digital story. They also made sure to add titles and, in most cases, relevant photos to each Soundcloud to maximise their visual impact on the final story.

The reporters in the field all managed to find interesting audio material and get it back to the newsroom. We also got lots of really useful photographic evidence of buses standing idle round the corner rather then en route! All students reported finding Soundcloud easy and fun to use.

Some students has borrowed my windshield to experiment with. Apart from one group which had put it on the wrong end (!! my fault. I should have showed them), they reported good results

Evaluation

The students loved Storify and several of them went away and experimented with it on their own. Really pleased about this!

One student said she’d have liked longer for the exercise so that we could have rotated roles. I agree but on the plus side, she said she’d go and experiment with Storify on her own which is a good outcome!

Overall, the audio quality needed some work. That was mainly down to lack of editing. They needed to be ruthless with their material! This is largely my fault for not emphasising enough the need to edit BEFORE uploading the material. But on the plus side there was a great range of material and creative use of the medium. They definitely used audio to enhance our appreciation of the story.

Interestingly, the students doubted they’d be taken seriously with an iPhone as opposed to a “professional” recording device. That’s at odds with the professionals’ view. I suspect it will change as iPhones become a more acceptable part of the broadcast industry. Watch this space!

Conclusion

This was a fun exercise and I would definitely do it again. There is so much learning and thinking involved. The tools worked well. They’re free and easy to learn and use straightaway so everyone benefits.

We were lucky with the weather on both days – bright and sunny with minimal wind. I’m not sure how much we would have got done in more typical MediacityUK weather (howling wind, rain, cold)

Recording audio with iPhone – tips from the pro!

Nick Garnett is BBC 5Live’s North of England correspondent and an iPhone pioneer. These days, he works in the field almost exclusively using an iPhone. I recently saw that he recommended using an ordinary windshield on the iPhone’s internal mic. Does this really work?

  1. @nicholasgarnett Does an ordinary 50mm windshield really make big diff on iPhone? Just stretch it over the end?
  2. @LizHannaford yes. It’s great – better on 4/4s because the headphone cable is on the far end away from mic
  3. @LizHannaford it rolls off top end, eliminates all really bad wins noise and also makes it look a bit more like a mic for ppl being iv’d.
  4. I’d not thought about that. Does anybody else find that some interviewees take you less seriously because you’re using an iPhone rather than a stand alone piece of kit? Interesting point.

    Nick was speaking to me from Todmorden where he was reporting on a slaughterhouse which had been raided by FSA officials following the horse meat scandal.
  5. In Todmorden for #horsemeat (not to buy it, to report on it!). On R4 and @bbc5live (plus 1 o’clock tv) ALL at same time. The magic of radio
  6. @nicholasgarnett That’s great! Thanks. Sounding good from Todmorden, btw. iPhone?
  7. @LizHannaford yes but w/o windshield! Biggest problem is I keep losing them! Voxes recorded, edited, filed on Voddio & live on 3G luci.
  8. Ah, there’s always a catch…

    Still, he’s definitely convinced me to try a windshield. I’m still not happy about using an external mic (kinda defeats the object of using an iPhone?) but I’m also concerned about the noise problem when you use the internal mic outside. The windshield – if I can keep hold of it – could be the answer.
  9. @LizHannaford this is why we should just use iPhones as they are w/o mics. this is a monstrosity.arqspin.com/s/3ogn0clmt5boo

  10. Here’s the monstrosity Nick refers to.
  11. @LizHannaford & from an interviewers pov too: a mic is seen as part of iv process but intimacy of no mic = v honest & revealing iviews
  12. We seem to have started something here. Another 5Live reporter joins the discussion!
  13. @LizHannaford indeed, tho as @nicholasgarnett points out people are far more comfortable w an iPhone in front of them.
  14. @LizHannaford also allows much faster filing of material than even w a radiocar or filetotraffic.co.uk on wifi for BBC. Cc @nicholasgarnett
  15. @rowanbridge @nicholasgarnett Intimacy v professionalism? Would some people equally see iPhone as amateurish?
  16. In the meantime, do read Nick’s excellent blog, full of practical advice and experimentation for audio reporters on the go.
    And thank you very much to Nick for taking the time to answer my question.

How do you teach Twitter?

I’ve spent a lot of time this past week trying to find ways to show people how Twitter can make their work life easier/simpler/more fun. I’m not sure how succesful I’ve been. Social Media is a drip drip process that has to be worked on. You can’t become an aficionado overnight. But here are a few thoughts.

The Social Tweeter

20130204-194940.jpg

I got the first year undergraduate students in my Digital Journalism class to create their Social Media portraits so I could get a better idea of how they use different platforms – if at all.

The vast majority use Social Media a lot, mainly Facebook, Twitter and YouTube. But they’re using it almost exclusively to keep in touch with friends and follow celebrity news (it’s not called SOCIAL media for nothing.)

A few of them are blogging or following other people’s blogs.

Soundcloud is quite popular for sharing music they’ve made and finding other people’s music. There were one or two Pinterest users who said they liked finding cute DIY ideas they’ll never use!! There was also one Reddit fan.

There were a few who didn’t have a Twitter account or who did have one “but then realised they didn’t need it.”

So the task is to get these students to realise they already have the skills and experience (in most cases) to use social media like a real journalist. What they now need to do is crank it up a bit and find out how they can use social media in a more sophisticated, more professional way. But it’s hard getting people to turn their favourite social platforms into yet another work thing!

I decided to try to amaze them with the power of Twitter as a search tool! Don’t just google “Salford” when you want a story idea or an interviewee. See how much deeper you can get with a really well filtered Twitter search! So I started by showing them a few of my favourites – Followerwonk which is a great way to search Twitter bios, Listorious, a useful people search and list directory and Trendsmap which is a fun way to search local Twitter trends. Then I hit them with the big one – search operators! This was totally new information for every single one of them. They had no idea you could interrogate twitter so closely. I handed out copies of the list of operators (one between two to encourage collaboration) and then gave them some Twitter Tasks to perform. It’s based loosely on Sarah Marshall’s MozFest social media training session but I’ve simplified it into a bite-sized chunk which I think works better with students who may need a bit of convincing about all this kind of stuff.

•Find 2 Manchester Evening News journalists on Twitter
•Find people talking in a positive way about the film Django Unchained.
•What are people tweeting about in Cape Town, South Africa?
•Find three people near Birmingham talking about the High Speed Rail link (HS2)
•Find a very recent photo or video from MediaCityUK.
The last question was a bit of a trick. I “planted” a photo on Twitter for them to find. Well, it got a few smiles….

The tasks gave the more advanced Twitter users plenty to keep them busy whilst I went round to each individual student (I had about 17 in each class) starting with the ones who were less experienced. The social media self-portraits were really useful in finding out who might need a bit more support early on and who would be able to work through the tasks independently. I was able to spend a few minutes with each student getting them started, answering specific questions, gently encouraging. I made sure to explain to them how these techniques could help in real journalistic scenarios and, crucially, help them get their assessments done.

Interrogating Twitter in this way really was a revelation to them so it was great fun for me to be able to share this stuff.

My colleague, Alex Fenton, who shares the teaching on this module, used another approach with the class the following week.  He got them all to send out one tweet using our module hashtag #DigiJourno. Even this was new to some of the students. They were encouraged to retweet the most interesting/relevant ones. Again, it was a nice, bite-sized chunk of Twitter that slotted into the theme of the session without overloading anyone. It’s very easy to put people off Twitter for life by drowning them in information! I’d tried to introduce lists and Tweetdeck but that was probably a step too far at this stage and was definitely off-putting to some in the class – although the more adept twitter users immediately saw the benefits.

And it was a revelation to the students to find themselves in a university class where you were actively encouraged to spend time tweeting!!

The Reluctant Tweeter

Away from university, I found myself discussing twitter on two separate occasions last week with friends who work in the media making radio programmes (not news programmes so they wouldn’t describe themselves as journalists). Both had had bad experiences with twitter.  One had been ordered to tweet by a manager but there was no thought-out strategy to this so the producer was left confused about the aim of the tweeting. She’d missed the one training session available. The other friend had been on a training session but it had seemed boring and irrelevant. Unsurprisingly, they both felt very negative about twitter and saw it as an extra workload being imposed on them.

The upshot of these conversations is that one of the friends is coming round for coffee one evening next week and I’m going to try to persuade her that it’s worth giving Twitter a second chance. Again, I think advanced search is the way to her heart. Show her how Twitter can help her find fantastic programme guests then all the rest will follow! You’ve got to make it relevant to people’s work life otherwise they just see it as an extra, time-consuming task they just don’t want to do.

I am genuinely excited by this challenge! I’ll let you know if I win her over. Then I’ll use that success story to work on Friend #2. Ideally, I want to spend a day at work with her putting her favourite contacts into Twitter lists…..

If you have any tips for teaching Twitter, I’d love to hear from you.

CodeClub in Manchester: Bringing it all back home

Manchester has a pretty good track record when it comes to computing so it seems like the perfect city for CodeClub to thrive.  There’s just so much talent here!  And I say this as a Scouser…

So today CodeClub volunteers and enthusiasts from around the Greater Manchester area got together at the fabulous MadLab in Manchester’s Northern Quarter.  Some of us already knew each other either in Real Life (they’d visited our CodeClub in Mellor) or through Twitter or the NW community forum on the CodeClub website.

photo-52

What we discussed

It was all very informal.  Anne (my fellow Mellor volunteer) and I talked about our experience setting up CodeClub and answered questions about how to go about it and how the projects work.  The CodeClub website is a bit sparse on these details and this can make it all seem quite daunting.  In my experience, it was really useful to reach out to other CodeClub volunteers around the country to pick their brains.  But ultimately, every school is different so you do just have to take a leap of faith and accept there’ll be a few niggles along the way.  But I think it’s good that we now have this little supportive community to help each other out and share experience.

It was really interesting to hear how other people had got involved and why we were so committed to giving up our time to this project!

Next Step

We definitely want to meet again!  We only scraped the surface today by the time we’d introduced ourselves.  We want to talk about how we can spread the word to other schools or encourage more developers to get involved.

But CodeClub is only the starting point.  The group of volunteers in MadLab today had so many good contacts/ideas/projects they were already working on which all tie in with the CodeClub ideals. For example, Steven Flower - who kindly set up today’s meeting -organises U18 events at MadLab and is involved in Young Rewired State and CoderDojos.  I’d love to encourage some of our CodeClub kids to come along to a big event like that.  And my daughters too!

We also loved this cheeky chap….

photo-51

He’d hitched a ride with Dr Andrew Robinson from the University of Manchester who has been doing great work promoting fun projects using Raspberry Pi.  His tweeting chicken even caught the attention of ITV news!  He’s been writing worksheets to help children build these projects themselves and there’s a whole set of YouTube videos which are really fun to watch (Disclaimer- no hamsters were harmed during these demos, Andrew says :-)  He’s also taken these projects into schools.

To be honest, it’s beyond my capabilities (unless I devoted a SERIOUS amount of time which I just haven’t got) but I’m really hoping my far cleverer fellow volunteers at Mellor would enjoy taking CodeClub in this sort of direction in future.  The first step would be to encourage the children to attend events at MadLab where this kind of fun stuff is available to play with.  The second step would be to arrange sessions to train volunteers how to do something simple with, say, the robotic chicken.  They could then have the confidence to try it out with their own CodeClubs.

DJ Adams did a great job noting down web resources for all the different stuff we discussed and he’s started a Delicious list with it all which should be a useful resource.  Thanks, DJ!

Maybe we’re being a little ambitious but that’s no bad thing.  We’ve got a lot of catching up to do if we’re to create a new generation of computer programmers.  And if we can’t do it in Manchester, then where else?

My challenge for 2013. What’s yours?

What’s the point of 2013?  It’s the year AFTER the London Olympics.  It’s the year BEFORE the Tour de France comes to Yorkshire.  It’s a year without focus or excitement.

So, having accepted that 2013 will be sad and meaningless, we need to create our own individual methods for getting through what will seem like an endless 365 days.  There’s no LOCOG any more to do this for us.

My advice is to set yourself a January challenge.  With luck, it’ll take you beyond January and into the latter stages of February.  Then we can regroup and think how we’ll get through the rest of the year.

My January challenge is to collaborate on writing a chapter of a book about teaching with team projects in Higher Education.  It’s being edited by Dr Janice Whatley from the Salford Business School at the University of Salford.  My contribution will be a tiny part of the overall book but it’s still a challenge.  I’m very new to academia and the demands of academic writing.  I’m hoping to learn lots from the people I’m working with on this chapter.

Our chapter will explore a session we participated in during the PGCAP (Post Graduate Certificate in Academic Practice) Core Module in the Sep 2012 semester.  We formed action learning sets which worked together to “flip the classroom” as we explored different learning theories.  Each action learning set was asked to investigate a particular learning theory (in my case – experiential learning).  Our challenge was to check the relevant Wikipedia entry for inaccuracies and gaps and add our findings to the specific page.  We did that pre-session.  Then the whole class came together and mind-mapped our learning theories to present to the rest of the group.  Q & As followed as we challenged and sought relevance for each of the learning theories.

IMG_4728

I found editing wikipedia really exciting! Could I really delete something without the whole internet collapsing?

IMG_4671

I was then hoping to go to a Manchester Girl Geek wikipedia edit day to learn more about writing and researching for wikipedia because women are under represented – but other work stuff got in the way.  Can we have another one please?

But back to the book chapter.  I’ve not done collaborative writing before and I’m intrigued to see how it works.  I’m used to “owning” what I write and then letting a second pair of eyes see the finished project and make what adjustments they see fit.  Collaborating on a google doc is a very different process.  Will it make me more self-conscious about what I write?  Will I be intimidated by the quality of my colleagues’ work?  How will I feel when somebody re-writes my work?  Will I ever dare to re-write my colleagues’ work beyond simple proof-reading?

So far, I’ve volunteered to look at some of the literature on using technologies for collaboration and how to make groups work.  I’ll be starting with Laurillard, Wenger, Conole and Jenny Moon.

My main challenge is how to get any meaningful work done whilst my daughters are off school…..
