RasPi.TV, RasPiO Duino and HDMIPi on the Gadget Show

A few weeks ago I was approached by the production company that makes the Gadget Show. They wanted some shots of things people have done with their Raspberry Pi. So I invited them to browse the RasPi.TV YouTube channel and see if there was anything suitable. In the end they selected clips from four of my videos, I gave them permission to use them, and last night the show was aired. The videos used were part of a ‘Raspberry Pi hack’ slot involving making an internet radio. You can find the whole show here Here […more…]

Followup on Raspberry Pi Model C - I'd like to thank my agent - Easter Eggs

As many of you gathered, yesterday’s post was an April fools joke. I’ve decided to leave it exactly as it is so anyone who missed out can still see it. There are a lot of ‘Easter Eggs’ in the photo of the Pi model C. You can get a high resolution view if you click the photo… I’d Like To Thank My Agent A few weeks ago Jamie, Tim and Mike came up with the idea of a spoof ‘Pi model C’ and Mike asked me for a high resolution photo of the Pi 2 […more…]

Raspberry Pi Model C

They’ve done it again. This time with almost no leaks. Today marks the launch of the next model Raspberry Pi, the model C. It’s an upgraded version of the Pi2 model B with some exciting new features. “People have been whinging since day one about 100 Mbit ethernet. Frankly we’re sick of it.” Says Eben Upton, “But while we were in the Far East recently, we found a new supplier who had some really good value Gigabit chips, with matching ports. We negotiated a deal. As you know, price is a key factor in Pi […more…]

Pete Lomas Talks to Alex Eames at the Raspberry Pi Birthday Weekend

At the Raspberry Pi 3rd Birthday weekend, I met Pete Lomas for the first time. Pete is a Founding Trustee of the Raspberry Pi Foundation (in his spare time). For his day job, he’s Director of Engineering at Norcott Technologies. Pete has been involved in the Raspberry Pi story since very near the beginning. He designed the original model B & A production PCB. I had a chance to have a chat with him on day 2 of the Raspberry Pi birthday celebrations. If you’re a Pi geek or interested in how it all happened, […more…]

Raspberry Pi Birthday Party Weekend

Well that was a wonderful, but tiring, weekend. Last night I got back from a weekend in Cambridge where 1300 people got together to celebrate all things Raspberry Pi. There were two lecture theatres, two large workshop areas, a large marketplace area and a show-and-tell area. The facilities were perfect, with plenty of space at the Cambridge Computer Laboratory. I took part in two discussion panels and gave a short talk on PCB Design for Beginners. I also managed to take in talks by Eben Upton, Dave Honess, Pete Lomas and Dave Akerman and I […more…]

Updated Pi Family Photo to include Pi 2 B

Obviously I’ve been fairly pre-occupied recently with the RasPiO Duino kickstarter (2 weeks in, just 1 week to go). But within the last week, at least 3 people have asked me if I’ve updated my “Raspberry Pi Family Photo” to include the new Pi2 model B. I realised, last week, when Zak Zebrowski, Matt Manning and Carrie-Anne all asked me about it, that “it’s become a thing“. I finally made time for it this morning. It takes a couple of hours to dust them all off, lay them out straight and get the lighting right […more…]

Interactive Graphing for the Web on Raspberry Pi using Plot.ly

I’d never done graphing on the Pi or in Python before, but for my KickStarter tracker I wanted something that… was web based would work in Python had decent instructions I could get going with fairly quickly I’d seen Rachel Rayns tweet about using plot.ly for graphing the temperature output of her Chef’s HAT sous vide cooker. I know Rachel loves “human readable instructions”, as do I. So I thought there was a good chance the plotly documentation was good. I decided to give them a shot.

Have a go at Arduino Programming on your Raspberry Pi

Today marks a rather special day. I’ve just launched a KickStarter campaign for a brand new Raspberry Pi add-on board called the RasPiO Duino. “Why is that special?” I hear you ask. Well it’s special for us because it’s our first fully solo venture in hardware. Also, my wife Malgosia is coming on-board to help with the kitting, shipping and admin. So it’s the start of a new family enterprise as well, which is all very exciting. It’s been in the works for a long time, but certain other things had to line up before […more…]

Raspberry Pi2 - Power and Performance Measurement

The new Raspberry Pi 2 has a quad-core CPU (BCM2836), but it costs the same as the previous B+. All that extra CPU power isn’t a completely free lunch though. If you use it, it’ll cost you slightly more electrical power than the B+. But how much? That’s what we’re here to look at. In my testing, hammering different numbers of cores in parallel, it worked out at roughly 50 mA (250 mW) per core. But before I show you the full results, let me back up and show you how we got them because […more…]

Raspberry Pi 2 - the New Quad-core A7 Pi2

New Raspberry Pi 2 Launched The Raspberry Pi 2 is out today. What? They only just launched the B+ and A+? I know! But you know tech companies like to spring surprises on us. It’s remarkably similar to the B+ in layout (in fact you might say the B+ was a ‘stepping stone’ towards Pi2) but has some significant upgrades… So What’s New With The Pi 2? Actually the video covers it pretty well, but if you prefer to read… It’s a quad-core A7 CPU with the same VC4 GPU as the original Pi. It […more…]
