Witty Pi Full Review

Back in July I did a mailbag video and got you guys to vote on which item I should do a more in-depth review of. WittyPi got about 50% of the vote by the time I had to make the decision. So here is the UUGear WittyPi review. WittyPi is an A+/B+/Pi2B add-on that gives you a safe on-off switch and enables timed shutdowns and startups of your Raspberry Pi. It has a battery-backed realtime clock (RTC) that controls the startup times and allows your Pi to retain the correct time even if not connected […more…]

New Official Raspberry Pi WiFi Dongle 3-way testing Vs ThePiHut and Edimax

A few weeks ago, Raspberry Pi launched a new official WiFi dongle with the following specs… 802.11 b/g/n USB 2.0 BCM43143 chipset 150Mbps maximum throughput Supports Access Point/Infrastructure mode Works with Raspbian out of the box (other OS yet to be supported) It’s been designed by the Raspberry Pi hardware team, uses a Broadcom chip and has a larger antenna than the other two dongles I’m testing it against. This makes it a little longer than the other two, but how does it stack up against them in terms of performance? That’s what we’re here […more…]

RasPiO GPIO Ruler

For some time now I’ve been using the wonderful RPi.GPIO Python library by Ben Croston. It’s great for using the General Purpose Input Output (GPIO) ports on the Raspberry Pi to control things and read inputs. I’ve written at least 14 tutorials on it (listed here) over the last couple of years. But I still find myself needing to look up the exact commands to use. I’ve made a crib-sheet which is really useful, but pieces of paper get lost. What I really want is the most used commands in a portable, accessible form that […more…]

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,
