From ICE to EV – Test driving Nissan Leaf

Just before Christmas my Subaru Impreza had a seemingly catastrophic coolant problem. I arrived at my school governor training (4 miles away) in a cloud of steam from my bonnet. The car needed a low loader to get it home, but all that took a while, so it was lucky I had the course to attend.
We had been considering a new car. We have a Honda FRV with has 6 seats and loads of room, is automatic etc. Then we have my scooby which doesn’t really get the chance to get used as much. as I work from home almost all the time most of my journeys are to take @elemming to the train station and pick her up. Driving to the supermarket or shops and most importantly heading off to Choi. All of which are about 6miles round trip.
I have an interest in tech of course, so electric vehicles (EV’s) always sounded interesting but there is a problem with causing the entire family to be early adopters if it is just for the sake of early adopting and spending significant money.
We had looked at normal Internal Combustion Engine cars (ICE). All very nice, but very few things were going to be as close to my driving experience with the Scooby. Hence all the new cars I figured would disappoint in some way. I have had the scooby since before predlet 1.0 was born so that’s 11 years. So it has seen some major changes in life, predlets born, leaving corporate life, moving house, taking up a martial art etc. It has also been very reliable. However things have to move on.
We took a punt and test drove a Nissan Leaf. This was particularly good test drive wise as they gave it to us for 7 days. Having an EV for a week gives you a chance to see if it really does fit the in with the family and out needs. It let me do some experiments too.

The first objection most people have to an EV is the range. Unless you buy a £100k Tesla you are going to be getting a car that has a 100 mile range, a 50 mile round trip. When you are used to 250-350 miles in an ICE that seems not great. However, remember I only needed this for the short 6 mile round trips. You can get a lot of those on 100 miles of battery, plus they return home, where a recharge can occur is need be. In addition we already still have a petrol Honda FRV for those long journeys. So really the range is only a problem if the other car is in use and one of us need to do a longer range journey. If this situation is going to occur is can be planned for as many EV suppliers offer petrol hire cars as part of the package. Of course this is assuming you couldn’t charge on a journey. Which you can.
So on these short hops locally an EV is ideal. It has plenty of charge and plenty of scope to just jump in and use it.
One of my concerns that any car would just not be as entertaining as my Scooby was kicked right into touch straight away. Even a relatively low end car like the Leaf has a fantastic feel to it. They feel very light, in a responsive lightness not a flimsy lightness. They also accelerate. The 0-60 on the Leaf is abut 7.5 seconds. My Scooby was about 5.9 when it was new. However… the profile of an EV means it has constant torque through the entire range. There is no specific gearing. Even a ICE automatic changes gear, or has kick down to accelerate. The Leaf just accelerates, whatever speed its goes. Without the engine noise it, and very little road or air noise the speedometer is really the only indication of speed. You hit 50, 60 and 70 very quickly on the motorway, but once at them the speed almost feel the same. This is a good thing, it means cruising at any speed is easy and acceptable. You are not between gears or struggling to justify the 5th gear change.
My drive to Hedge End I did firstly just normally in regular drive mode having not topped the car up after the station and school run. So I was on about 85/90% battery. So I very quickly experienced the anxiety that all EV driver get. In ICE you have a petrol needle, its not very accurate but you know you have a few miles left after any warning light or hitting the red. Up until that point you just drive. The you maybe have to eek it out a bit more to make it to home or a petrol station. In the EV you have a lot of information, accurate information, telling you battery levels, power usage and estimated range. If you hit the aircon/heating and floor the accelerator on the motorway you see you project range tumble. The climate control knocks 7 miles off the range. I realised I was burning too much as I reach what would have been a half way point and headed for home, this time with the eco button and full mode B energy recovery. I approached home and the warning lights started flashing. I only had 15 miles left of range. Panic!. The sat nav asked if I needed directions to a charger! PANIC!!!
Of course this is all slightly ridiculous as by now I am 3 miles from home. Even with climate control on full I would make it, but it does play on your brain.
The next day I thought I would try the same journey but top up to 100% at home before I went. Home charging is just plugging into a 13 amp plug (though you can install higher rate quicker chargers for a few hundred pounds). It means if you go to a friends house and need a top up you can (though thats a bit cheeky, I am not sure we have the social etiquette for that sorted out yet)
This time I drove on the motorway back down to the south coast on full Eco (where the max power is dropped and the effects of the throttle are lessened) and mode B where more engine braking is applied when you ease off and the battery is charged with that power.

So we have the simplicity of just putting in drive and pressing the accelerator, but we have the complexity and thought of energy management and recovery. Easing off before coming to halt to get your green lights lit on the left of what would be a rev counter.
I got to the same point with plenty of return charge but still drove back on Eco. Because of the perceived speed it didn’t seem to matter in a cruise on the motorway to have turned the wick down on the car. The energy management and recovery made for fun game. Something Nissan have spotted by rewarding you with a christmas tree/lives indicator that gradually fills up as you do good work. It sounds mad but it works.
I managed to max it out on one journey- Yay !

On the second Hedge End trip I was slightly less freaked out by the battery indicator but as I got to Winchester services, and as the car had an Ecotricity card in the sunglasses holder I thought I would try a rapid top up charge.
There were 2 bays both without cars in them, so it fitted to experiment. I held the RFID card up and chose my rapid charge mode. The nozzle comes with the plug, it was a massive device compared to the home charger as it had lots of sliders and locks. Once engaged charging started.


I was on about 33% and went for a coffee and a comfort break. It was about 15 minutes and I was not waiting around tutting.
I was impressed that Costa reminded me I was driving a leaf and had my little Eco xmas tree game to play in the car by drawing on the top of my coffee with a similar motif.

I returned to the car, went to cancel the charge and it asked me to swipe the card again. This of course makes sense to stop people unplugging you out of spite. I disconnected and saw I now had 66% charge (64% when I took the photo and faffed around before hand). Not bad!

So for the 10 miles home I dropped the eco and the full energy recovery. Pulling onto the motorway it was like having a brand new car as it woke up from its space cruising stasis and went full alien monster.
When I got home I had used 20% of the battery already. So it really hits home how to moderate driving when needed, not accelerate quick so hard. Much more so than a petrol car that you don’t really think about it much until the needle gets low.
One of the other gadgets on the Leaf is is great set of cameras surrounding the car. The dash display that doubles as the GPS, radio and everything else switches to cameras automatically for reversing, but also can be switched to camera when at low speed/ stationery heading forwards.
A reversing camera makes a lot of sense, but also the ability for it to generate an apparent birds eye view is fantastic for parking in bays.
Here I am safely parked and stationary with the forward camera working. It is in black and white as it is in night sight mode. You can see in the dark

The birdseye view can be replaced with a camera on the front left quarter, i.e. the turning blind spot, by pressing a button.
Reversing also provides the angle of trajectory super imposed Augmented Reality style on the reversing camera. Here I a parked but in reverse on out drive way showing the obstacles (in colour this time)

We had a top of the range Leaf so it had everything on it. A spoiler with a solar panel to charge the second battery (a regular car battery used for lights etc). Voice control, bluetooth hook up, it understood my iPhone playlists when plugged into the USB, heated seats etc etc. It had GPS builtin and knew where a particular network of chargers were to navigate too. Full ownership gets you hooked up (along with your charger) to CARWINGS, which is Nissan’s internet of things network for automotive. This lets you control the car setting via an app, asking it to warm up in the interior in the morning. Or you can, as I did, just use the timer. When on charge it will draw house electricity to power the AC and warm the car for a set time and temperature. There is of course no point going out and starting the engine as it doesn’t heat up like and ICE.
I enjoyed looking at the energy information screen quite a lot. It felt like playing Elite Dangerous or Eve Online balancing the power usage.

I also was entertained by the graphic for the “don’t put a baby seat in the front” which was the most extreme one I had seen. The middle picture almost looking like a theme park ride icon.

So it seems that I am quite taken with the Leaf, it has a very particular set of skills 😉
We are going to test drive the BMW I3, though that offers a range extender, a motorbike engine and 9l tank to give another 50 or so miles. However I am not sure if that is worth us getting as it would almost never be used except in extreme circumstances when it might better to hire a car or take the train. Also BMW only seem to offer a 30 min test drive, and after that if they think you are worthy a few hours test drive. Our nearest BMW dealer is in Eastleigh too which is a pain. However BMW, and all car people you need to ramp up the test-drive time!
Lets see what happens next 🙂

Happy 2015 – Flush 16 – Are you Santa?

I hope everyone is getting ready for a great 2015 and had a good break (if you got one). For a first post of the year I am going to start early and mention Christmas :). This though is just to let you know that issue 16 of Flush The Fashion magazine is live and my slightly esoteric “Hello, Are you Santa Claus?” article this issue looks at probability and how that features in Quantum theory and a light hearted look at multiple universe theory.
The whole magazine is cool and interesting as usual from @tweetthefashion. I say this each time but it is still true, the amount of effort and skill that goes into making this magazine is fantastic and it’s an honour to have my content included.
If you look at the embed below you will find me on page 22 but just before that there are some great images of food skateboarding by Benoit Jammes called Skitchen
So where else do you get such an eclectic combination of quantum physics and skating fruit?
See what you think.


The direct link to my article to get your brain kicking in for the new year is here
Now would be a good time to kick in with my epredator theme tune to introduce it 🙂
Now to work out what 2015 is going to bring. It looks like there will be a lot of VR and AR with so many headsets and combinations of tech emerging. It is very exciting and it all needs to be powered by virtual world content. So another year of metaverse evangelizing before it becomes the norm then 🙂

Theme tune

A while back I invested in the Unwinnable Kickstarter campaign to create a weekly quirky look at video games. I picked as one of my rewards a personal them tune composed by George Collazo I was intrigued at what might come out of such an exercise. Those of us getting a tune done filled in an interesting set of questions. I got a tweet just now for George saying my tune was ready. I click play and loved it, then read what George had used as inspiration.
” I tried to combine super spy James bond style coolness with pure Bruce Lee badassey with Enter the Epredator.” Yes tech and martial arts in an awesome tune!
Thankyou George! I love it.

Some fun with space science and physics

Last week on the excellent Prof Brian Cox show Human Universe TV show a wonderful real life experiment was shown. It is common at school to learn about gravity, about mass and weight. Often the original concepts from Galileo around dropping objects are covered and considered. We now see footage from space and weightlessness.
However in this experiment a giant vacuum hall is used to show the difference air resistance makes. Being told a heavy thing like a bowling ball or a light thing like a bunch of feathers we are taught from our own observations that the ball will drop faster. In this clip though the air is removed from the environment and we get to see the ball and feathers drop at the same rate. It is spooky, despite knowing the science. You can see from the scientists reaction how special it is to see this. It is real life magic at work.

I have shown the predlets and they are bemused and intrigued too.
I have always wanted to the predlets to feel the wonder of science. We spend a lot of time on screens looking at the virtual. This is all great, but the real thing can be even more amazing.
We just took delivery of a proper telescope this week to be able to check out the night sky. This was in part from being at a friends and all the kids wanting to see the moon close up with their scope, in part because of the wonder at the size of the universe playing space games on Oculus Rift like Elite Dangerous and the influence of TV shows like Human Universe.
I remember looking up in awe at all the constellations and planets, and of course the moon when I was about 7 and armed with a pair of binoculars.
This box arrived from Amazon

After a little bit of assembly it looked like this.

The Equatorial mount on it is, if you are used to 3d applications, really interesting. 3 axis of movement but up is not always up :). You get this in 3d when your rotations are relative not absolute.
There are lots of things to consider setting it up, but just with the basics I pointed it at the moon for us last night. We used the 20mm lens that came with it. We got a pretty full frame moon.
Taking a photo was tricky as I did no have a camera mount, and only the iPhone. However jiggling it around a bit I ended up with this

The predlets we somewhat agast seeing the craters in this close. Obviously they have seen photos before but seeing it yourself certainly does something different. It did when I was a kid so fingers crossed.
Later I spent some time exploring how to line the thing up, adjust the right bits and pieces and there is lots more to explore 🙂
Also as a side effect, as kids always like to play with the boxes of things, we ended up with a lot of cardboard just on the day school asked for some to be brought in for a makefest that they are doing in years 3/4 🙂
TV/internet/games etc might be considered sedentary and lazy, but they can be used to inspire and explore and raise awareness.

Gastronomy Geekin’ – Heston style

Last night I was very fortunate to be able to go to Heston Blumenthal’s Fat Duck restaurant in Bray to partake of the tasting menu. I was there as a guest with @elemming‘s work colleagues who had agreed to celebrate a particular milestone. I have been a fan of Heston’s work on TV and have watched everything he has done. It is because it is not simply cookery but science and art combined. He talks about food experiences in terms of memories that they evoke not just the taste. He pursues ideas on the transformation of food in the same way many makers and tech geeks combine things just to see what will happen. There is a lot of snobbery and pretentiousness in food and drink, yet somehow for me he cuts through that with that youthful enthusiasm and passion, making the complex simple.
I am not going to attempt to be a “food critic”, I was there and in the zone enjoying and absorbing it all, like all wonderful experiences there will be bits and pieces of meal that will surface in memories over time. There were at least 14 courses over the space of the 5 hours we were there which is a little above the brains 7 +-2 things to retain in short term memory!
The evening started with a wine list experience that was such a weighty tomb it looked like a spell book from Harry Potter. I was driving and have decided not to drink at least until after my Choi Kwang Do black belt grading, but I still enjoyed watching the choosing experiences. I also was very impressed with the depth of knowledge and detail the sommelier had. Thousands of bottles of wine and he almost knew the GPS coordinates of the individual grapes by heart. It is not a cheap night of food but the wine prices put anyone thinking they are a bit flash back in their place. The most expensive was £8000. That was not one for our table!
I had a fruit juice to drink but the process to create it and the addition of Chamomile to the blood peach extract that was not squeezed but teased from the fruit over several hours was an instant eye and taste bud opener. Yet it was rather nice!
The menu does a explain a little of what follows but does not indicate the depth of attention detail and distilling down of flavours and textures that just keep coming throughout the experience. It isn’t supposed to be a meal, it is an art gallery or a concert. The day after I am left with ringing taste buds the same way I am left with ringing ears after a really good music gig.

Having an aperitif that is foamed, flavoured egg white that is poached in a vat of steaming liquid nitrogen at your table is not only fun but amazing science in action. The resultant spoonful had already got me interested and fascinated. It was the start of a theme of textures and transformations. The poached meringue had a solid structure, yet melted and almost evaporated as you put it in your mouth.
There were a number of things that on stopping and admiring the work it was amazing how things had not just crumbled, melted or shifted on the plate. Or jelly like layers that were incredibly rich reductions that a tiny taste of filled your mouth with flavour.
The Mad Hatter’s tea party presents you with a gold watch style tea bad. The watch and its gold leaf dissolves in the the clear tea put releasing a rich stock. It is fancy Bisto, but the mechanics are fascinating.
The Hot & iced tea just before the main dessert was a trick that uses unusual ingredients to create a very strange effect. The glass of tea is presented and you are asked to drink it in the orientation that it is deliver in. As you sip the tea, the left side of your mouth is warm , the right side is cold. It uses a non starch Gel to make an almost runny liquid but one that retains its form so it does not flow into the opposing temperature side. It is rather like floating cream on an irish coffee but not in horizontal layers but vertical ones. Wonderful stuff!
The main dessert was called Botrytis Cinerea and it is where I finally buckled and took a photo. I was trying to not get obsessed with taking snaps of the food. There were people in the restaurant with SLR cameras pointed at each plate that arrives, but you can’t consider that rude or weird in a place that is there be a multi sensory experience. (There is also not specific dress code, just a come as comfortable attitude).
So this dessert

looks like a still life sculpture of a bunch of grapes. It is the name of a fungus that eats into grapes a grey mould. So this dessert looks like grapes that have gone mouldy? Yet this mould in nature has two sides to it. One side destroys but the other called “noble rot” enhances the sweetness of dessert wines. Obviously we were not eating the rot, well I don’t thing we were, but it led to a really amazing dish..
Each of the ‘grapes” was a complex combination or preparation. The large green one had a crisp shell, had runny caramel inside but was also peppered with space dust so crackled as you ate it. Some of the others that looked solid were in fact delicate sorbets and ice creams. The meringue one again was solid to the touch but instantly disappeared in a puff of flavour on the tongue.
Every dish had had elements like that. The tapioca transformed into sand (with microscopic sardines/krill added to it) and the crab/fish flavoured froth of the “sound of the sea”. (This dish comes with a large conch shell with an iPod hidden in it and earphones so you can listen to the sound of the sea whilst you eat your way through a beach scene of flotsam and jetsam)
It wasn’t all “tricks” though. The main course was an Anjou Pigeon, delicately cooked so that it had a rich flavour linked to a soft texture.
So yes it was good. we all enjoyed it immensely.
In someways I wish I had not seen the dishes on the TV before so the shock and surprise would have been greater, however in other ways this was like when we went to see BB King in concert. A legend of the blues. I had heard the songs before, even tried playing them but nothing beats the live experience and the event itself after you are already immersed in that world. Rehearsal, practice and simulation are are brilliant but they also need to lead up to the real thing too.

Computers getting smarter?

It’s time to share another edition of the Flush the Fashion magazine and this time I have written an article inspired by the apparent passing of the Turing test a few weeks ago. As with all my articles it is just a starting point and a look at some of achievements and current state of the art created by the company I worked at for 20 years IBM. Deep Blue and Watson. The article is titled “R U Intelligent like what I am?”, it finished with a bit about Timeless Decision Theory and Newcombe’s Paradox so it is probably the freakiest article yet 🙂
Huge thanks once again to @tweetthefashion for another very full and exciting edition of the magazine and the really great layout and pictures to go with my words.
A direct link to the article is here
It’s on page 125 🙂


There is also the iOS version and a google version linked here
I hope you enjoy it, and the magazine. It’s great fun to write like this, and there always seems a subject to get into and explore making itself appear through serendipity.

In the night garden

Our garden at home was experiencing some odd activity. The predlets had planted some spinach and some corn and carrots. One morning the spinach was looking a little flattened. The predlets then started an investigation. It was a bit like CSI Basingstoke. They found (and photographed) what they thought was evidence of an animal. So the hunt is now on.
Having watched lots of wildlife shows I wondered how easy it was to get an outdoors camera with an infra-red trip. I had never bothered looking before as I assumed these were quite uncommon. It turns out trail cameras are very prevalent 🙂
So I bought one.

This LtL-6210M has all sorts of interesting features.
It has a zero visible light LED flash to enable the night camera to work, it has side sensors to get the camera ready and waking up before something moved in front of the lens. It can take stills up to 12Mp! and HD video too.
It has lots of timer settings and also is able to just do time lapse shots.
Apparently it can last 12 weeks on its 8 AA batteries which is pretty amazing too.
In the base is a small screen and control set so it can be operated and used without needing to take the SD card out of the machine.
So we set it up overlooking the veg patch last night. I had run it during the day to see if it worked at all, and it spotted us in the garden.
At around 9pm when it was dark I popped down to see if it was still working.
It did catch me approaching it

However, I am thinking my checking may have meant that turned it off or reset it as this was the last picture it took 🙂
So I think I need to do a few more experiments before I become wildlife photographer of the year!
Still, these things all take time, but it is a cool bit of kit to try out. What we really need it a weather proof Kinect 2.0 ?

Rocksmith 2014 – Now that is clever learning software!

A few days ago my a new version of my favourite console application arrived Rocksmith 2014. I had seen the press release video of some of the new things in Rocksmith and they did look interesting. For once my expectations have been exceeded though. Rocksmith 2014 session mode is probably the best piece of software I have ever seen or used. That is a pretty big claim to make but it makes playing the guitar just feel right.
They have improved a lot of other things about the regular tune learning too. Just in case you are not aware this is a guitar “game” that you plug a real electric guitar into you console/PC and the device acts both as an amp but also as a guide. It knows the notes you are playing.
So to learn a tune the notes stream at you indicating the fret and the string (colour coded as well as positional). If you hit the note, great, it will start adding more notes and chords in to level you up. Miss and it will start to make life simpler. This is with real music, the original versions in every style under the sun.
The new version provides challenges in each song and coaches you through, there is less focus on the score, though score attack mode still exists. It is about the playing and about it feeling and sounding right.
The previous version had a way to isolate a section or a riff and repeat it, first slowly then speeding up. The new version has this but with lots more options about the number of repeats, the initial speed the level jumps etc, all easy to adjust. It also lets you just hit a button whilst playing the whole song and jump to riff repeating where you are in that song. Something that was awkward to navigate to before.
All the old DLC from the previous version is ported to the new version, though…. they rather cynically charge you another £7 or so to do so. If you have bought a lot of tunes then I would have expected some loyalty bonus. The additional tunes are now also £1.99 which seems steep, but then they are not just the music but the structure of the song and how to learn it. If you think how much guitar lessons might cost it is minimal really.
The real extra star of the show though is session mode. However it has been built it provides, to me at least, a fantastic backing band for any guitar noodling I feel like doing.

I love playing the blues scale, in the past I have tried playing along with famous tunes on CD’s and tapes, obviously that never gets to the standard of the stars of the blues world that are playing those tunes. I have also had backing tracks with books etc they are fine if you are trying a fixed thing to play. Session mode lets you load a band, lots of styles and types. Blues has 5 or 6 specific types on its own let alone Rock, Metal, Indie etc. In the set up you can pick a key, a scale and things around tempo and the relaxed or rigid nature of your backing band.
Session Mode
Then you start to play. Initially the band are doing nothing, but the first few notes on the scale you have chosen (which is highlighted on the fretboard on screen) starts to set the band in motion. The drummer and bass kick in at the sort of pace and intensity you start. Even just playing the scale slowly gets them going. Before long you find a little riff to play and maybe some chords and before you know it the other instruments keyboards, and guitars are joining in filling you room, in this case, with the blues. If you have set it to a more formal structure the band will start making the changes as in a 12 bar blues and the the onscreen scale suggests the notes that work in those step changes. Of course you can play what you want. Speed up slow down the band goes with you and it doesn’t just feel like a load of loops being triggered. There seems to be a more complex analysis of the notes you play that gets the band doing their thing. You can almost nod to them when you want to step it up or hit a quite solo. It is stunning.
I am not a musician by any sense of the imagination, but I have tried guitar many times. The previous Rocksmith taught me a lot, something that it continues to do in learning songs. However session mode is the delight. It is a very clever, very patient, non judgemental band. Experimenting with riffs and scales in lots of styles is truly enlightening and relaxing. It is not about trying to hit a note, keep up, make a score, copy a sound but instead find a self expression through making music.
It is not without it’s downside but one does have to suffer for one’s art darling
Ow #rocksmith2014
My fingers have now hardened a bit again, you just have to soak blisters in lemon juice and keep playing on them.
There was something else very cool about 2014. It is even better for 2 guitars now. Predlet 2.0 plugged his little electric guitar in and we jammed in session mode. He explored what happened as hit hit notes fast and slow and we even did a bit of riff turn taking. A right noise for everyone else in the house but we had fun. We then moved on an made more racket playing Billy Idol White Wedding which is a bit go a fave tune of ours 🙂
I am not on their payroll, just a very enthusiastic fan. If you like guitar you have to get this !

Flush Magazine 10 – Airbags and ice skating

I took inspiration from @elemming recent fall ice skating in which she broke her wrist for this months article in Flush Magazine. It seemed a few things came to mind around safety and in particular the use of air bags in all sorts of places.
You can read it and see the really nice layout, once again great job making my words and ideas look awesome on the page. Thankyou again @tweetthefashion for all the hard work getting this issue out there.
The direct link is here


As usual its quite a mix but does share a common theme, mars landings, motorbikes and ice 🙂
I hope you enjoy the article, and the rest of the excellent magazine.

Heading into space. Tweet me from there?

This months issue of Flush magazine is out online and there is a slight departure subject wise. It is a travel special, lots of great articles to read. I was thinking what can I do for a travel issue and then it dawned on me that space tourism was a great future tech platform. I had in my mind things around the Virgin Galactic craft but then many more things flowed from that including a rather surprising project involving social media and Mars.
Thankyou once again to @tweetthefashion for putting together another great magazine.
You will find my article “Ground control to ” on page 92 (just a few down from an interview with Raymond LeBlanc 🙂


It grows my little portfolio of “proper” articles which makes me happy anyway 🙂
It just goes to show there is a lot of tech out there and a lot of ways it impacts us emotionally too. When you hear about some of these projects and think what would that really be like to be part of it, all powered by human endeavour, it fills you with hope rather than focussing on the negative vibes that permeate our lives. We are not here to just grind away, counting the cost. We are hear to further knowledge and experience.
