This website is a log of my hobbies, passions and projects. It will hopefully over time fill up with helpful advice to
encourage, inspire and guide others with similar interests.

June & July:


The past couple of months has seen a major heatwave here in england with daytime temperatures topping out above 30°C on a few of the days. As this never lasts in our temperate climate, I have been making the most of it getting out and about with a few trips in the camper and a lot of days walking the local countryside.

One major project that needed doing was a little bit of DIY removing the 1980s mock beams on the ceiling and re-plastering the dining room. Once the beams were down, It was obvious that it would be easier to re-plasterboard the ceiling rather than trying to skim over the rough plaster. Next time I plan to do a job like this i will try and time it not to coincide with a heat wave.

Removing beams and replastering dining room.

One slight mishap was my Yamaha Clavanova piano the sustain pedals stopped working. It turns out that when moving it around the room we must have rolled over one of the dogs balls or something of that sort of size as the circuit board that send the signals from the pedals had broken. I would put it down as a design fault as the circuit board was well protected in a metal housing, but the circuit board wiring connector protruded through the bottom of the housing. This meant anything slightly bigger than the gap between the underside of the connector and the floor had the potential of breaking the circuit board if the piano was moved over it.

Repair to the Yamaha Clavinova sustain circuit board

I managed to make a temporary repair of the board by drilling through three of the wider tracks and pulling the break together with copper wire, then soldering the copper wire in place. The micro tracks were much more difficult soldering 0.05mm2 wrapping wire to bridge the breaks took a real steady hand. The repair isn't pretty, but at least my piano is working again whilst I search for a supplier of a replacement board.

Blender has taken a back seat these past months, but I am in the early stages of starting a new CNC machine build project and been roughing out in Blender what will be a stiffer, yet lower friction design than my previous router. Also I am designing new circuit boards to utilise the L298 Duel Full Bridge Driver. Keep an eye out as I will post more as the project progresses.

In June I attended the Leonard Cheshire Disability Newlands House and Village Feit, which meant purchasing and setting up a 3M square covered gazebo. With lots of visitors to the Feit my portrait work was well received and I had some great comments from many of the people that attended.

Also a few new drawings went out to customers.

May:

I have been concentrating on preparing my VW camper van ready for a lot of travelling this year. It has also been a busy month for pencil portrait work, so unfortunately there isn't much to show on the Blender or Technical Illustration front.

I was one of 50 artists exhibiting at the three day Lichfield Festival of Artists this month. It was a great experience with thousands of visitors coming to see the excellent and varied artwork on display. It gave me the opportunity to do a live demonstration of my techniques and I chose to draw a horse. There was too much work and far too much talking to complete it at the exhibition, but I managed to complete it over the following two weeks.

April:


I returned to do a little more refinements on the Spitfire Mk9 cutaway model this month. There are always areas you can look back at and think I wish I had done that differently, so I decided to make a few modifications / additions.

There has been some good feedback about the 2D views of the model, even making the Blender artist gallery, however static images never do justice to a complex 3D model. With that in mind I left my computer working for a few nights to render the 360 degree rotation video below.

The video is also on my technical illustration website www.robertburkeillustration.co.uk which is slowly taking shape.

Eagle pencil portrait

Besides commissions I have added another personal work to my Portraits and Art website, this time an eagle. This is the second bird of prey drawing and will be part of a collection I am planning to draw.

March:


Ball Valve Project

In a bid to add content to my Technical Illustration website, I have took a break from the Industrial Robot Project which is going to take me quite a few months of spare time to finish, to concentrate on a smaller project.

The ball valve below was modelled using a number of references picked up off Google images and not representative of any one manufacturers product. The model is used to show a representation of how they work and a generic idea of what components are used to make up the ball valve assembly.

The ghosted image below is made up of three images and uses CSS with a little java script to transition between them. I also have a CSS only version working on my www.robertburkeillustration.co.uk website.








The idea was to create an animation of the ball valve fading to a cutaway section and then showing the the water flow stopping and starting as the valve is operated.

To show how the ball valve is assembled, I have also animated an exploded view of the components coming apart and then reassembling.
The hope is the video below will show the type of freelance work I can create to add to training presentations, websites or company brochures etc.

I have added another personal piece to my collection this month, which was quite a challenge as the reference photo had very little contrast. The sleeping fox also has the most scruffy, complex fur I have drawn, quite a time consuming project but satisfying to complete.

February:


The industrial robot / palletizer project has advanced very quickly this month, mainly because the February weather isn't the best for outdoor activities, so there is more Blender time.

Also as a bit of a rant, it was because I have been badly let down by Virgin Media who have oversold internet access in the area to the point the local distribution router couldn't cope. Their "super fast broadband" was reduced to being unavailable for most of the days and dropped out the minute you you tried to look at anything more than a basic text page.

The first stage of the Palletizer project was to remodel the industrial robot and the image below shows the challenges you face when importing from a nurbs based CAD solids model to a surface mesh. The cylinder on the CAD model had 74000 vertices compared to the remodelled surface created in Blender of 3000 vertices.

Once the model was built I needed to add a rig to make it animateable and to make this easier constructed a simplified version of the robot. The initial rig works okay but requires two control points for position and rotation.

Since this animation I have modified the rig to work with only one control target for both position and rotation.

The model also needed a scene to work in so I have modelled a portal frame shed and pallet conveyor system. The video animation below is a tester to see how the scene will look.

January 2018:


I am starting this year with a new Blender project, to model, rig, animate and render an industrial robot. Most of my previous projects have all centred around modelling, so this one will focus more on the animation side of Blender and hopefully I will be learning and sharing my experiences with rigging, constraints and animation.

After learning from the Spitfire Mk9 project that you need to collect good references before you start modelling, I am pleased to say that for this project both drawings and CAD models are available from the industrial robot manufacturer. The CAD models however aren't in a format that is suitable for animation as the original solid model has been converted to a triangulated .stl file. There are far to many vertices on the .stl model and they aren't organised geometrically around the models features. The first job will therefore be to create a clean manifold mesh of the robot.

Spitfire Mk9 Modelling Project

After working on this project in my spare time for a full 12 months, I have brought the Spitfire Mk9 project to a close. It's been a great learning experience, especially in the organisation of large complex models and I have picked up some new Blender modelling techniques along the way. The most important thing I have learnt though is to gather all the necessary reference material before you start. With so much conflicting and inaccurate information on the web, I fell into the trap of starting the model with inaccurate reference images and it meant I had waisted a couple of months modelling before I had found dimensionally accurate plans and ended up having to deleat everything and starting again. However, through the process of this model I have learnt a lot more about the Cycles render engine and am pleased with the finished result. A larger version of the final image can be seen in the gallery
