RasPiO Duino Videos Complete

Last Thursday I decided I needed to do the “Analog Inputs Video” for RasPiO® Duino. All the other basic functionality was well covered in the previous assembly/setup/tutorial videos. There’s also the 47 page user guide (FREE Download – good intro to Arduino programming) and a GitHub repository with the example sketches in. But I wanted to complete the basic set of videos, so at midday I started planning. I filmed in the afternoon and cut the video in the evening. At about 2230 I was done, so I started uploading it to YouTube (~2.4 Gigabytes […more…]

RasPiO GPIO Ruler goes on general sale

You may remember I ran a KickStarter campaign in August for the RasPiO® GPIO Ruler. The KickStarter rewards were all sent out in the first week of October. (We finished shipping 3 weeks early.) So now it’s time to launch the product officially and make it available to all on general sale. If you missed out on the KickStarter, now you can buy one. In case you haven’t seen it before, this is what it looks like… What Is The RasPiO® GPIO Ruler? It’s a coding crib-sheet for RPi.GPIO, a port ID guide, a multi-scale […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…]

RasPi.TV Mailbag - July 2015

Today we’re getting a bit interactive. I decided to do a mailbag video, showcasing six of the things people have given me or sent in over the last few months. The items in question are… PiUPS Traffic Hat Official Raspberry Pi wifi dongle Shortcrust Plus Pi 2 (& B+) case Unicorn Hat Witty Pi You Tell Me Which One You Want Reviewed In More Depth I’m off abroad soon. I haven’t got room in the case to take all of these items. Let me know which is the most interesting to you and I’ll take […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…]

RasPiO Duino as a Lipo Monitor

I’ve been using lithium polymer (lipo) batteries since 2006, when I nervously shelled out £30 for a 3 cell 1600 mAh 10C HiModel lipo to power my EasyStar RC plane. I also spent about the same on a charger and balancer for it. Thankfully, all these things have come down a lot in price since then. I don’t think I’d expect to pay much more than £10 for an equivalent battery now. Typical lipo batteries for large devices have multiple cells. A lipo cell has a no-load resting voltage of 4.2 V when fully charged […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,

New Port ID Board for the Raspberry Pi B+ - RasPiO Portsplus 2

Today I’m launching the RasPiO Portsplus 2. It’s a simple port ID board for the Raspberry Pi model B+. It’s available over at https://rasp.io/portsplus2 but full information below… RasPiO® Portsplus 2 The RasPiO® Portsplus 2 board is designed for the new Raspberry Pi B+. It labels the ports clearly for you so that you don’t need to count pins. This will help you avoid wiring errors and damage… You can slip it over the B+ GPIO header if you want, or hold it next to the header (many people tell me they do this – and this […more…]
