OCR Raspberry Pi recipe card competition — win stuff just by thinking!

You may be familiar with the Raspberry Pi recipe cards that we developed with the exam board OCR. These are a great way to start using your Raspberry Pi: quick, creative projects — such as traffic light LEDs, singing jelly babies and Twitter-aware doodhas — that teach one or two new concepts and encourage experimentation and hacking. They are a great classroom tool too and we use them at our programming workshops.

I said “sing!” Sing louder you little gelatine chappie or it’s off with your head!

OCR want to make more recipe cards. Because they are nice like that. They know the best ideas for projects are living in your lovely little heads and they want to extract your weird and creative brain juices by means of a Trial of Creative Might.

The challenge is to design your own recipe for Raspberry Pi. You can do this by yourself or in a team. One winner or winning team from each age category will win a Raspberry Pi bundle including a T-shirt and will have their winning recipe featured on the Raspberry Pi blog (this means that you will be fabulously famous!). The three age groups are 12 and under; 13-15 and 16-18.

Your recipe must have fewer than 100 lines of code and cost less than £10 in parts. And no soldering allowed — we want to make this as accessible as possible.

The competition will be judged purely on creativity and imagination rather than technical prowess — you don’t even need to submit any code — so everyone has a chance to enter.

A Wing-ed Helmet of Ingenuity. Available from all good online retailers.

The closing date is 30 August 2013 so you have a few weeks to don those Winged Helmets of Ingenuity + 3 and impress us! Full details and terms plus the entry forms are on the OCR website.

Good luck!

I’m not doing very well… I think the problem may stem from me eating the Jelly Babies before I get a change to plug them in…

I suffer from that exact problem…

That’s OCRs fault I’m afraid…

This should not be confused with the “screaming jelly baby” experiment, where a jelly baby is immersed in molten potassium chlorate.

Funnily enough my original workshop “recipe” that this stems from used Scratch and an analogue sensor to make the jelly baby scream louder and louder the harder you squeezed. Kids loved it, but some adults thought that it was a bit macabre (which is the whole point of course :))

If you don’t need to submit any code, how do we know it’s possible in under 100 lines? ;)

Anything incorporating bare conductive pens would work… Too bad am too old to enter :/

“so everyone has a chance to enter.” Except for us over the age of 18…

… and under the age of six months. Rightly or wrongly we’d have to assume that they’d had help from a grown-up.

I remember in one of my scence lessons from school, your teacher got a jelly babie, and put it in this mixture, and it blew up, and reacte violently. something to do with the sugars/carbohydrates in the JB.

Just a little heat and some pure oxygen. No need to test if it’s heavier than a bit of wood or a duck. Woof. Proves it’s a witch’s familiar.

To my American eyes somebody is talking about Optical Character Recognition, but that must be wrong. What does the OCR in this article mean?

“You may be familiar with the Raspberry Pi recipe cards that we developed with the exam board OCR.”

Homer Hazel avatar

That is the same line as in the article. Repeating the line did not provide me with additional insight, but thanks for the attempt.

Attempt #2: OCR is an exam board.

Homer Hazel avatar

Thank you.

Us over 18s could always use the “Jellyatrics” babies thay made a couple of years ago.

Sounds interresting

Were the winners of the contest ever announced? Are there new recipe cards available? I want to get my 9-yo son back to hacking on the Pi (we messed with it a little during the summer), and these would be a good start. And if you still need ideas, he’ll probably come up with something on his own soon enough!
