RasPiO Duino Goes On General Sale With Free Arduino Programming eBook

Having completed the KickStarter fulfilment a long way ahead of schedule, we’re now ready to launch RasPiO® Duino on general sale. We thought it would be nice to launch it officially today at the Cambridge Jam. What Is A RasPiO® Duino? RasPiO® Duino is a small plug-on board for Raspberry Pi. It has similar functionality to an Arduino Uno, but is fully programmable from the Raspberry Pi. Once programmed, it can be removed from the Pi and used on its own. If you’re interested in the full product description you can find that here. Free […more…]

Twitter-controlled RasPiO Duino based Pan and Tilt, Tweeting, DropBoxing, Raspberry Pi Security Camera

Around about this time three years ago, I bought and installed five EasyN pan-and-tilt ip cameras to keep an eye on various viewpoints of our houses in the UK and Poland. I think they were about £45 each on Amazon. They’re not too hard to set up and they work tolerably well. The main downside is that their resolution is only 640 x 480 pixels, which is not enough to read a car numberplate from across the street. It’s fairly poor resolution, but you can see something. The colours are a bit washed out too […more…]

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…]

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…]

Mainly video today. A little video showing a few simple examples of the sort of things you can do with the RasPiO Duino. Obviously you can do much more sophisticated things too. My next step will be to control the speed of the LEDs using the light sensor and the analog inputs. Endless fun, and useful too, when you think that an LED could represent any device you wanted to control… Don’t forget to check out the RasPiO Duino KickStarter, which finishes in a few days,

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…]

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…]
