Some of the audience at the start. Note my lovely Surface Go running the whole thing…

Had a great time at the Leeds Sharp meetup tonight. I was there to talk about Air Quality, Azure Functions and Lora. With a guest appearance of my Air Quality top hat. I’m pleased to be able to report that every demo worked. Even the impromptu one that I wasn’t expecting to…If you want a look at the slide deck you can find it here.

One of the lovely things about the night was that the first two folks that I saw at the venue were a couple of Hull alumni, Joshua and Andrew . They were there to make a video of the event. So they did. It’s really good, they’ve caught the presentation content along with some shots of me prowling around looking nervous. I think I’ll hire them for all my events. They’ve put the video on YouTube, you can find it below.

Air Quality, Lora and Azure Functions at Leeds

I’m treading the boards again on Thursday evening this week in Leeds. I’m talking about our work with Air Quality sensors and whatnot. With a special guest appearance of the Air Quality Top hat. Should be fun.

If you live in Leeds you can register here. If you don’t live in Leeds you can still travel there and attend if you wish, but I’d probably draw the line at intercontinental flights to get there…..

Please note that, in a break with recent tradition, this session will not be rhyme. (unless they offer me money)

DDD North was super awesome

The best conferences are the ones where you go and learn a bunch of useful stuff and also like to think that you’ve told a few folks useful things that they didn’t know.

DDD North yesterday was one of the very best. I was blown away by the quality of the sessions, the enthusiasm of the audiences and the sheer good humour of the whole event. I learnt a whole slew of new stuff; from IoT development tools that you can run from you laptop through Mob based development techniques, some nifty .NET library tricks and a lovely take on how to use generics in C#.

I even presented a session of my own which I hope taught people a few new tricks. I was so engrossed in my bits and bobs that I totally failed to take any pictures (which is most unlike me and a measure of the quality of the occasion).

And to make it even better, it was in based in my favourite university and old stomping grounds in Hull, so I just had to get up, grab breakfast and tootle down the road to take part.

Hats off to the organisers for making it all work, the sponsors for paying for great food and a lovely setting and the speakers for taking their time out to spread knowledge. You could pay an awful lot of money in conference fees for an experience nowhere near as good as this one.

If you ever get the chance to go to one of these in the future, you really should.

DDD North is tomorrow and I'm presenting


I’m getting rather excited. It’s DDD North tomorrow. Four tracks of excellent computing content crammed into the lecture theatres in Hull University. A whole day of splendid sessions.

And one from me.

I’m on at 2:30 pm in Lecture Theatre A in the Robert Blackburn Building talking about Azure Functions, Air Quality and a bit of LoRa. I’ve just finished the slide deck and the demos. Should be fun. If you happen to be on campus at Hull you really should come along. I’d love to see you.

AI Frenzy at c4di


We had a Barclays AI Frenzy with Codepen Hulll tonight. There was plenty of frenzy in my session, where I built a complete Machine Learning application in around 12 minutes. There were also a bunch of other great sessions from Sherin Matthew who gave a splendid overview of the field, Aparna Garg who showed a lovely example of an advanced AI application and Neil Gordon who talked about research at Hull University and how companies can work with it. 

If you want to see my sample application and the presentation you can find it on Girhub here.

Barclays AI Frenzy at c4di

Just a quick heads up about an event that I’m speaking at. We had a call about the content yesterday and it all looks very interesting.

And there are free refreshments.

If you want to know more about Artificial Intelligence, see whats happening in the area and meet up with like-minded folks to talk about how you can use the technology, you should come along to the event next week. At’s at c4di on Thursday evening. I’m doing a demonstration of how easy it is to take some data and then build an application that uses AI. You can sign up here.

Barclays AI Frenzy Event

I’m doing a tiny session in the Barclays AI Frenzy event in February. I’m going to be showing just how easy it is to make a C# AI enabled app, starting with training data and ending up with a working program. I’m not sure how much frenzy I’m going to bring along, but I’ll do my best.

There are going to be lots of other speakers too, along with a chance to talk to a bunch of like-minded folks.

The event is on the 21st of February starting at 17:30 in the afternoon. You can sign up here.

Talking at the Black Marble Architecture Forum

What a great audience looks like…..

What a great audience looks like…..

Drove to Leeds today to give some sessions at the Black Marble Architecture Forum. All new material. Which is a bit scary to be honest.

Anyhoo, first up I did a session for the student track. This was great fun. I told the story of our work on Air Quality as part of the Connected Humber group. The main thrust of the talk was that you can really can make a difference just by doing stuff. I’ve made a screencast of my talk which you can find here.

The audience gathering before my next talk…

The second talk was all about the Internet of Things, LoRa and Azure Functions (which are awesome). Another great audience, some great questions at the end. One chap asked about 3D printing and I said I’d put something in the blog about it. My advice, take a good hard look at the Anet Prusia A8. I’ve not got one - my six year old Ultimaker is still doing sterling service for me, but for a fairly low investment this looks like a good one to go for.

I’ve made a screencast about LoRa, I’ll do one about MQTT and another about Azure Functions.

Rob at Black Marble Architecture Forum


I’m doing a couple of sessions at the Black Marble Architecture Forum next week. However you can’t get to see both of them unless you are both a student and an industry professional.

Black Marble have this lovely policy of running a one day event for both students and developers, with twin tracks. For the first time they’ve let me loose on the professional track, so I’ll be talking about Azure IOT Hub for them and Air Quality Sensor building for the students. There’s actually a bit of cross over between the two - I’m going to use Azure to store the air quality data. It’s going to be quite fun.

The event is in Leeds on Wednesday next week. I’m not sure if you can still sign up but the event page is here.

Hornsea Radio Rally

When I was a lot (and I mean a lot younger) Radio Rallies were a big thing. Lots of fascinating components and bits and pieces for sale. You could watch the progress of half-finished projects as they moved from one person’s “Bring and Buy” stall to another over the years. This was in the days when talking to someone a long way a way (perhaps even abroad) was not a thing that anyone did because it was either too expensive or impossible.

Nowadays, with the internet and Skype making the planet a tiny, tiny, thing, the lure of long distance ham radio has diminished a bit. But there are still people doing it, and I bumped into a bunch of them at the Hornsea Amateur Radio Rally today. The event was held at the lovely Hornsea Floral Hall and things were pretty much as I remembered. There was stuff that people had brought out of their sheds to see if anyone was interested, along with a few component suppliers. And even a lot of valves.

It was great. I vowed only to spend cash and keep all my bank cards safely tucked away in number one wife’s handbag. So I only spent fifteen quid. I got a programmable led badge that I think I can connect to a Raspberry Pi, some tools, a UV torch for playing with fluorescent printed objects and a few other bits and bobs. Great fun.

Hull Pixelbot at the Digital Awards

Hull Pixelbot finalist in two categories. Yay!

Hull Pixelbot finalist in two categories. Yay!

Hmm. Three blog posts in one day. What an interesting life I lead….

Anyhoo, today it was time to put on my best smart casual wear and head for the Bonus Arena for the finals of the Digital Awards. This was all rather exciting. Firstly because the Hull Pixelbot is a finalist in two of the competition strands, secondly because I really fancied having a look around the new Bonus Arena, which is where the event is being held.

Well, the arena is is splendid. After an lovely meal, accompanied by a saxophonist with a fantastic illuminated saxophone, we went through to the arena for the awards themselves. We had a few speeches at the start which were all shot through with a theme that this is a great place to do digital business. One speaker made the point that they were feeling a bit sad about being in the bottom 48% of Lightstream users in Hull for network performance. He was cheered up a lot when he found that this still meant he was in the top 2% of network users in the country.

And another fun fact stood out for me: A third of the optical fibre in the UK is under the streets of Hull. The government has set what it calls an ambitious project to get all households in the UK connected to fibre by twenty thirty something. KCOM (the telecoms company that provides home networking in Hull) will achieve this in Hull by the end of March next year. Other cities in the UK are now playing catch up with us. Big time. And, we don’t just have networks. We have talent too. As the awards were about to show.

Mark Dolan was a great compere

Mark Dolan was a great compere

I’d not seen that much of Mark Dolan before to be honest. But by gum he’s good. After a brief (and very amusing) comic set to break the ice he got things going and presided over the proceedings with some wry observations and knowledgeable comments. The finalist in each award category was introduced by a short video of them in action. Which for me meant two sessions of squirming in my seat as I watched pictures of me and my stuff on the enormous screen. Although I loved the moment when the audience went “Ah…” when they saw a bunch of Hull Pixelbots doing one of their little dances.


I didn’t win. I didn’t expect to, to be honest. I’d taken a look at the field and come to the conclusion that there were much better entries in my categories than mine. But I was mightily honoured to have been picked to get into the finals. And I did get two lovely certificates in really nice frames. One for the office at c4di , one for home. And If you check the awards lineup you’ll see that the Hull Pixelbot was actually first in each category. Alphabetically…

It’s a measure of the confidence that I’m seeing in the area that it can put on what I consider to be a world standard awards ceremony. I’ve been to a few of these over the years and the whole setup, the organisation, the venue and the presentation really was world class. And, and this is the really wonderful bit, so were all the finalists. The winners were real stand-outs.

I was especially pleased to see Hayden Barton win “Young Digital Person of the Year”. I first met Hayden at a Hardware Meetup at c4di when he showed me a neat little device he’d brought along. “That’s nice” I said. “Where did you buy it?”. His reply marked him for greatness in my book. He said “I made it.”.

After the awards we staggered home tired and happy. Thanks to every one who put the event together. Great fun and great for the region.

Rob at Ron Dearing UTC

30041497068_3f43db175b_z (1).jpg

Despite arriving a tiny bit late, I had a great time at the evening event at Ron Dearing UTC today. A whole bunch of folks came to see me to talk about technology and I showed off some Hull Pixelbots, my silly goggles and the prototype air quality sensor that we’re working on over at Connected Humber.

Of course, I totally forgot to take any pictures at the event. Silly me. That’s why there’s a rather splendid picture of Whitby pier at the top of this post instead of anything relevant to the night.

Anyhoo, I talked to a bunch of folks and gave out a bunch of advice. Summarised thusly (posh prose)

  • If you’re into computing, start playing with the Arduino device. It’s cheap to get started (much less than a video game) and extremely creative. Buy a Sintron Arduino kit (search ebay or Amazon for “Sintron Arduino” to see a selection of kits. The one that is around thirty pounds is good value. If you want to start cheaper, come along to a Connected Humber event (we have them on the first and third Thursday of the month at c4di starting at 6:00pm in the evening). We’ll sell you an Arduino and some hardware for five pounds and give you some things to do with it. You can find out more here.

  • Start learning about 3D design. Lots of people that I spoke to were already doing this. The ability to think in 3D will stand you in good stead whether you go into fields ranging from video games to product design. There are lots of free packages you can use, I quite like FreeCad, although it can be a brute to get to grips with. If you’re a programming type, take a look at OpenScad. If you want to use a free, professional level, tool take a look at Blender. It will really make your head hurt, but you can do awesome things with it. Take a look online for howto videos for these tools. If you don’t like the ones that you find, make some better ones of your own.

  • Which brings me to my third point. Lean to write and talk. When you start doing something, start writing about it too. Put your writings into a blog, a personal diary or a log. I don’t mind. The important thing is that you do this. I made the point lots of times that you can learn a good living, and have fun, as a programmer. But if you also have the ability to write well and are good at communicating your ideas this makes you much more useful and interesting to employers, getting you even more interesting and rewarding things to do. So you should work at getting those skills. Deliberately do things that take you out of your comfort zone. Practice talking to people (networking is a big part of success) and try to force yourself to speak in public. Trust me. It really pays off.

By the end of the evening my voice had just about worn out, as had the batteries in the robots. But it was great fun. And then I went home and had bananas and custard for supper. Such fun.

Heading Home


We were up bright and early and on the road home by 8:00. The whole event was fantastic from start to finish. They say the next one will be in 2020. I’ll be there.

There is also talk of “electromagnetic pulse” events being organised in the gap between the “fields” events. It would be great to set up one of these in the Hull area.

Anyway, time to head for home and then to get the Air Quality sensor working with the badge…..

Day 3 of Electromagnetic Fields

30697493918_ae94491dfa_z (1).jpg

Achievement Unlocked: Shower Ninja Level now at Master. Take a large waterproof bag for clean clothes and dry towel on the way in and dirty clothes and damp towel on the way out. Leave boots outside the shower cubicle, facing outwards so I can just step into them on the way out. I'm really getting the hang of this camping lark. Of course, it’s not rained at any point…..

Having settled into something of a routine the realisation is dawning that this won't go on forever and today is in fact the last day. Wah. I resolve to go to lots of sessions and get the badge air quality sensor working. 

After a great session on LoRa networking, and another on the scary way that you can hack into car keys, I went to some that were all about how the event itself. First up was a session on the making of the emf badge. It turns out that making a complete mobile phone device is actually quite tricky. Kudos that they actually managed to make it work. The next session was about power, amongst other things.


This is the power distribution to the tents in our area of the camp. There were a bunch of “Tardis” booths that contained nothing but distribution boards and, I suppose, a whole bunch of fuses and whatnot. These were connected to a backbone that was powered by a bunch of great big generators spread over the camp.

After the talks and another abortive attempt to get my badge to work with the Air Quality sensor, we went for a wander into the “Null Sector”. This was a seemingly haphazard collection of shipping containers that held, well, interesting stuff. The best time to see it is at night - of which more later - but there were quite a few things to take a look at, including a container from MSRaynsford that contained a kind of steam punk workshop with a laser cutter and some lovely things for sale. I ended up with a useless box (which I’ve always wanted) and a wifi controlled StrandBeest. Of which more later.

After some more coding we headed for the closing ceremony. Rather sad. There was enough content for several weeks I reckon, I wish there had been more of me to go to all the things that I know I missed out on.

The good news was that we still had the evening to enjoy, including some electric car racing that was great fun to watch. I was also able to practice my panning technique as the cars whizzed past.

I have no idea why there is a Christmas tree on the back…

I have no idea why there is a Christmas tree on the back…

As the night came down we ventured back into “Null Sector”. They had buttons you could press to send out great big gas flares, art installations, an RFID powered treasure hunt and a powerful laser light show. I did the best with my little camera, but the shots don’t really do the setup justice.
