Makey Christmas and a Hacky New Year!

Christmas lectures by Ben Nuttall

Our homes are full of technology that we typically take for granted and understand little. Your average smartphone or tablet, for example, is a “black box”, that deliberately discourages modification by tinkering and hacking. This Christmas, Danielle George takes three technologies we routinely take for granted – the light bulb, the telephone and the motor – and shows you how to hack your home as part of the Royal Institution Christmas Lectures broadcast on BBC Four.

Lecture 1/3 The Light Bulb Moment: First broadcast Monday 29th December

Inspired by Geordie inventor Joseph Swan, Danielle attempts to play a computer game on the windows of a skyscraper using hundreds of light bulbs. Along the way, Danielle will show the next generation how to hack, adapt and transform the technologies found in the home to have fun and make a difference to the world.

This year’s Royal Institution Christmas Lectures have been inspired by the great inventors and the thousands of people playing with technology at their kitchen tables or tinkering in their garden sheds. When Joseph Swan demonstrated the first working light bulb in 1878 he could never have dreamed that in 2014 we’d be surrounded by super-bright LED screens and lights that could be controlled using mobile phones.

In this lecture, Danielle explains how these technologies work and show how they can be adapted to help you realise your own light bulb moments. She shows how to send wireless messages using a barbecue, control a firework display with your laptop and use a torch to browse the internet. (via richannel.org/the-light-bulb-moment)

Lecture 2/3 Making Contact: First broadcast Tuesday 30th December

Inspired by Alexander Graham Bell, Danielle attempts to beam a special guest into the theatre via hologram using the technology found in a mobile phone. Along the way, Danielle shows the next generation how to hack, adapt and transform the electronics found in the home to have fun and make a difference to the world.

This year’s Royal Institution Christmas Lectures have been inspired by the great inventors and the thousands of people playing with technology at their kitchen tables or tinkering in their garden sheds. When Scottish inventor Alexander Graham Bell demonstrated the first telephone in 1876, he could never have dreamed that in 2014 we’d all be carrying wire-free phones in our pockets and be able to video chat in crystal clear HD across the world.

In this lecture, Danielle explains how these technologies work and shows how they can be adapted to help keep you connected to the people around you. She shows how to control paintball guns with a webcam and turn your smartphone into a microscope, whilst also investigating a device that allows you to feel invisible objects in mid-air.

Lecture 3/3 A New Revolution: First broadcast Wednesday 31st December

Inspired by the Royal Institution’s very own Michael Faraday, Danielle attempts to use simple motors to construct the world’s greatest robot orchestra. Along the way, Danielle shows the next generation how to hack, adapt and transform the electronics found in the home to have fun and make a difference to the world.

This year’s Royal Institution Christmas Lectures have been inspired by the great inventors and the thousands of people playing with technology at their kitchen tables or tinkering in their garden sheds. When Michael Faraday demonstrated the first electric motor in 1822, he could never have dreamed that in 2014 we’d be surrounded by mechanical devices capable of performing nearly every human task.

In this lecture, Danielle explains how these robotic and motor-driven appliances work and shows how they can adapted to help you kick-start a technological revolution. She shows how to turn a washing machine into a wind turbine, how Lego can solve a Rubik’s Cube and how the next Mars rover will traverse an alien world. (via richannel.org/a-new-revolution)

If you miss the television broadcasts, the lectures will also be available on BBC iPlayer for 30 days then at richannel.org/christmas-lectures.

This will (probably) be the last post of the year at O’Really, so if you’ve visited, thanks for reading during 2014. Wherever you are, whatever you’re up to, have a Very Makey Christmas and a Hacky New Year in 2015.

Creating with the Raspberry Pi vs. Consuming Apple Pie at the Manchester Raspberry Jamboree

Thirteen year old Amy Mather aka @MiniGirlGeek steals the show at Manchester Raspberry Jam 2013

Last Saturday, the first ever Raspberry Jamboree rolled into town, organised by the unstoppable force of nature that is Alan O’Donohoe (aka @teknoteacher). The jamboree looked at the educational value of the Raspberry Pi (a $25 computer) one year on from its launch on the the 29th February 2012. Here are some brief and incomplete notes on some of the things that happened in the main room, aka ‘Jamboree Central’. The workshops and other events have been covered by Jason Barnett @boeeerb.

A key feature of the Raspberry Pi foundation (and the Jamboree) was neatly summed up by Paul Beech (aka @guru) who compared the Raspberry Pi to various Apple iThings. Paul’s view is that when it comes to computing, Apple gives you a “sandy beach, sunbed and cocktail” to passively consume digital content with while the Raspberry Pi gives you a “desert, knife and a bottle” to actively create new things (see his tweet below).

Consuming Apple Pie on a sandy beach, with a sunbed and a cocktail

Engineering evangelist Rob Bishop used Apple Inc. to illustrate what the Raspberry Pi is about in his talk ‘one year on‘. Rob pointed out that a huge amount of effort at Apple Inc. is put into making Computing invisible and seamless. This is great if you’re consuming content on your iPad or iPhone, and what many users want – easy to use, with all the nasty internal gubbins tucked away, out of sight. This is tasty Californian Apple Pie, which many of consume in large amounts.

However, invisible computing is a problem for education, because it is difficult to demonstrate the Wonders of Computer Science (Brian Cox’s next TV series) with a device like the iPad.  Many of the internals of modern devices are completely inaccessible, and it’s non-trivial for budding young engineers to build anything very interesting with it particularly quickly.

In contrast, the Raspberry Pi can be challenging to setup, just getting the Operating System up and running isn’t always straightforward. However, there’s a ton of interesting stuff you can build with it: Nifty robotics, bionic bird boxes, musical hackery, twittering chickens, live train departure boards, internet radiossinging jelly babies and loads of other pideas. Try doing that with your iPad…

Creating with Raspberry Pi in the desert, using a knife and a bottle

Most of the jamboree focussed not on Apple but on the things that can be created with Raspberry Pi: the What and Why and When And How and Where and Who with keynotes from Steve Furber [1] and talks and panel sessions from:

A highlight of the jamboree was the closing keynote given by the thirteen year old Mini Girl Geek on what she’s been doing with her Raspberry Pi. MiniGirlGeek (aka Amy Mather pictured above) stole the show with her demo implementations of Conway’s Game of Life in Python. [update: see video below]

What’s interesting is that Conway’s Game of Life is used as an exercise for first year undergraduates in Computer Science at the University of Cambridge. So it’s great to see teenagers mastering the “knife” of Raspberry Pi, and reminds us that Raspberry Pi is no “sunbed and cocktail” but with a little patience, ambition and talent there’s plenty to capture the imagination of young people about Computing.
