Hacking robot dinosaurs with a Raspberry Pi with Dr Lucy Rogers

Last weekend, geeks, tinkerers and hobbyists gathered in Guildford for EMF Camp, a 3-day technology gathering for like-minded individuals. Talks ranged greatly in their topics but this one in particular caught my eye and I was lucky enough to catch it via live stream. Now, you too can listen to Dr Lucy Rogers talk about how the theme park Blackgang Chine, on the Isle of Wight, recruited her, some programmers and some engineers to bring their collection of animatronic dinosaurs up-to-date. Using some electronics wizardry and visual programming language Node-RED, they were able to program the dinosaurs to react to passers-by and make the theme park experience that much richer. You can watch a recording of Lucy’s talk here. If you want to browse the rest of the EMF Camp talks, visit this page.

Skycademy 2016 starts at Raspberry Pi headquarters

The Foundation’s Dan Fisher has just blogged about Skycademy, which starts today in their Cambridge HQ. 30 educators were invited to take part and they are currently learning the ins and outs of High Altitude Ballooning. You can read more about Skycademy here, follow the trials and tribulations of the teachers and learners on Twitter here and track tomorrow’s 10am flights by using the links below:

Help a Masters student at UEA understand the Raspberry Pi brand

word cloud - branding

Here’s an interesting proposition for you. John Nguyen is currently studying for a Masters at the University of East Anglia on the subject of Brands and Branding. He has been in touch and asked for assistance with his research, and the Raspberry Pi community can help!

He has identified Raspberry Pi as a brand with a great community and wants to canvas the opinions of members of that community. So, if you have a spare 5-10 minutes, he’d really appreciate it if you could complete this online survey.

He’s also asked if there are any community leaders out there who would be willing to be interviewed as part of the research. I said I’d ask around, so I am! If you would be willing to be interviewed over Skype, please get in contact with me and I’ll arrange an introduction.

Thanks in advance to all those who take the time to help John!

Learn to Program with Minecraft – Book review

This is a somewhat belated review – I’ve had the book since January and have only just retrieved it from my suitcase! Apologies to Craig and No Starch Press; but the wait was worth it!

Learn to Program with Minecraft is a classic example of a good idea done well. Author Craig Richardson takes a great model of teaching and applies it to the world of Python programming, using Minecraft as an outlet for your coding efforts.

Approach and Content

IMG_20160806_152806

This is very much a ground-up book about programming, but is a lot of fun as well. First of all, you are taken through the steps required to set your computer up with Minecraft and the programming environment (a ridiculously easy prospect on a Raspberry Pi, slightly more convoluted for Windows and Mac). Then, you are introduced to programming concepts that you need to know and then you are shown how they work in Python: this includes variables, mathematical operators, types, conditions and loops. The book then introduces you to functions, lists, dictionaries, tuples and for-loops before moving onto more advanced concepts such as file I/O, module importing and, finally, object-orientated programming.

The entire book is written in the format of Tell-Show-Do-Challenge. You are first of all told what you are going to do, and how it works. Then you are shown example code that highlights your knowledge in practice, via the Minecraft world. You are then invited to extend, complete and even fix the example code. Finally, you are challenged to take further steps to cement your knowledge and have some more fun.

Knowing your Stuff

Craig Richardson quite clearly knows his stuff, and how to present it. Each part of the book has been created as a ‘mission’ to complete and he manages to convey difficult programming concepts clearly and succinctly. The book, being based on Minecraft, is, of course, a lot of fun. Nothing in recent years has captured the imagination of kids quite like Minecraft, and the 3D world is used to great effect. You’ll soon be teleporting and building, and of course it’s so much fun that you aren’t going to realise quite how much you’re learning until you’ve become as much of an expert as the book can make you.

Solid Foundation

What I was most impressed with is that ‘even though’ it’s all based around Minecraft, the book is a solid foundation in Python programming. As I’ve said before, it’s “ground-up” and gives you a firm understanding of those key principles that every programmer needs to learn. There is a focus on debugging, particularly in the early sections, and part of the challenge of the book is to learn how to spot bugs and know how to fix them. The book expects you to make mistakes, but wants you to learn from them, which is, of course, the best way to learn anything.

The Icing on the Cake

If you’ve been reading this blog for a while, you’ll have seen other book reviews and you’ll know the quality I expect when I’m reviewing them. In particular, the quality of the paper and whether or not it is printed in colour. I am pleased to say, if you hadn’t guessed already from the screenshots, that Learn to Program with Minecraft is printed in full colour. Moreover, the quality of the paper is very high and it feels like a very high quality publication. No Starch Press should be commended for the job they’ve done in producing the work as it’s a cut above what I’d expect from a programming book.

Conclusion

You know by now that I often give good reviews of products and books. This book, however, has blown me away. The quality of the writing, the way it is structured, the fact that it is full-colour and the sheer volume of knowledge imparted in it’s almost-300 pages is highly impressive. Very nice job, Craig. Very nice indeed. 🙂

You can buy the book from No Starch Press or from Amazon for around, or slightly under £20 or $30.

Boot your Raspberry Pi through an Ethernet cable

Gordon Hollingworth has just published his second blog post on the Pi’s new booting modes. This one is all about booting over Ethernet with no SD card on the client Pi. The new functionality is documented here and there’s a handy tutorial to getting a Client-Server relationship set-up using two Pis here. You can read some additional notes and Gordon’s intro on the Raspberry Pi blog.
