Programming Raspberry Pi. Raspberry Pi | An ARM GNU/Linux box for $25. Take a byte! LIVE WEBCAST: Inspiring future generations with open hardware - the Raspberry Pi. Eben Upton From: The IET Young Professionals' Event 2012, Savoy Place, London, 18 October 2012 18 October 2012 IT channel Please login to view IET.tv Technology channel presentations. About the presentation In a world full of expensive, 'closed' consumer devices emerges the Raspberry Pi, a low-cost credit-card sized computer that can be plugged into a TV and a keyboard. The hope is to see it being used by kids all over the world to learn programming, but it also serves as an ideal platform for hobbyists to try out new ideas. Eben Upton talks about the transition from large, high performance systems to cheap, low power and potentially disposable hardware. But what does the future hold for these innovative and disruptive products? About the speaker Since 2006 Eben has worked at Broadcom where he is responsible for processor architecture.
In November 2008, Eben founded the Raspberry Pi Foundation to develop and market a 25 USD microcomputer for education. Build a Retro Computer: The Raspberry Pi! Programming the Raspberry Pi with Raspberry Pi co-founder Eben Upton. Introducing turbo mode: up to 50% more performance for free. Since launch, we’ve supported overclocking and overvolting your Raspberry Pi by editing config.txt. Overvolting provided more overclocking headroom, but voided your warranty because we were concerned it would decrease the lifetime of the SoC; we set a sticky bit inside BCM2835 to allow us to spot boards which have been overvolted.
We’ve been doing a lot of work to understand the impact of voltage and temperature on lifetime, and are now able to offer a “turbo mode”, which dynamically enables overclock and overvolt under the control of a cpufreq driver, without affecting your warranty. We are happy that the combination of only applying turbo when busy, and limiting turbo when the BCM2835′s internal temperature reaches 85°C, means there will be no measurable reduction in the lifetime of your Raspberry Pi. You can now choose from one of five overclock presets in raspi-config, the highest of which runs the ARM at 1GHz. What does this mean? Previous image (2012-08-16-wheezy-raspbian): Pi3D. Liz: Some news from Tim Skillman – which is going to be particularly interesting for those of you who wanted to use the accelerated 3D potential of the Raspberry Pi, but who didn’t fancy getting down and dirty with OpenGL ES.
Pi3D is still a work in progress, but there’s already plenty you can already it do with it if you’re interesting in playing with 3D models on your Raspberry Pi. Tim includes download links for the module and for some examples. Over to Tim! Pi3D is a Python module designed to open up the 3D abilities of the Raspberry Pi BUT with a difference: it will provide simple yet powerful functions for kids (and adults) to create 3D with very little knowledge of programming. The main aim of Pi3D is to instil some fun and excitement and get kids (and adults) coding! Eventually, Pi3D will import and render several 3D & 2D file formats, create 3D objects, fractal landscapes, compile scenes into vertex arrays and render shaders. Monday grab bag. We’ve had some people send us some great stuff this week – if you’re working on something cool that you think we might feature in a grab bag post, please mail me at liz@raspberrypi.org.
First up, some video. Linus Torvalds has been talking about Raspberry Pi (we will forgive him his insistence on calling it Raspberry P.I. because he is a massive hero of ours, and the fact that he ever mentions us at all is beyond fantastic.) The question about Raspberry Pi starts at 52m 19s. (The Nvidia bit earlier on is, broadly speaking, NSFW.) Steve Jones from iMica has put AROS, an open-source implementation of Amiga OS on the Raspberry Pi.
Greg Macaree has been using the Raspberry Pi as a crucial piece of wedding reception audio equipment, the whole setup nearly jeopardised by a milking machine (seriously). He says: For those not familiar, Sonos is a multi-room streaming hifi system. The scouts are using a pico projector with their Raspberry Pi - Biz's famous case can be seen on the table! Liz.
