Behind the scenes – timelapse video

 I was recently asked to help out at a Taekwondo studio shoot with photographer Ben Luckman. In between moving lights and backdrops around and generally being in awe of these guys’ martial arts awesomeness, I decided to shoot a little behind the scenes video and set up a time lapse camera in the corner of the studio to capture the whole session.

For the techie geeks out there, the time lapse frames were shot on a Nikon D70 tethered to a Macbook running Sofortbild timelapse and camera control software, shooting a frame every 12 seconds for the duration of the two hour shoot. I set the D70 to manual focus and exposure to avoid the camera hunting around and to give stable light levels. Video clips were shot on a Flip HD pocket video recorder and the whole lot was put together in iMovie ’11.

This is the result:

I’ve got a long list of things I’d do differently next time, but I think the concept seems to work quite well.

Roadster

I bought a new car from a friend a couple of weeks ago. I didn’t really need another car but it was a bargain and I couldn’t resist. It’s a 1990 Eunos Roadster (Jap import Mazda MX-5). Not sure if being 20 years old makes it a classic car or just old.

It’s not perfect. One of the rear dampers feels like it’s knackered and a bit bouncy so left and right cornering isn’t entirely consistent when pushed hard, there are a few paint chips and scuffs here and there, the diff needs an oil change and the stereo speakers are ready for the dustbin. On the plus side though, it has extremely low mileage, a new hood, a brand new stainless steel exhaust, two sets of wheels, a sweet running little engine and has just sailed through an MOT with no problems at all.

By my reckoning it should make for a very cheap little toy to stick in the garage and take for a drive on sunny days. Unlike my previous Roadster this one’s ‘just’ a 1.6. I say ‘just’, but the difference in power between this and the 1.8 is negligible and if anything I would say that the 1.6 is the revvier, more sporty engine. I think this one’s had an uprated flywheel too which feels great, especially on downshifts. Makes the VX220’s powerplant feel positively lazy.

I’ve only had a chance to drive it properly a couple of times so far but I’m absolutely loving it. It’s not fast by any stretch of the imagination but the steering is quick and precise, the brakes feel great (especially after driving modern over assisted cars), the gearchange is sweet and the raspy little exhaust puts a grin on your face when buzzing about with the roof down.

I think I’d forgotten what a pleasure driving could be.

I need to take a can of anthracite/dark grey paint to the naff looking red wheel centres and get hold of some cheap door speakers so I can listen to the radio, but that’s about it. New shocks and bushes would be a luxury but they can wait till next summer.

Pictures to follow soon no doubt.

Electric bicycle

If I’m honest, I’ve never really seen the point in electric bicycles until now. They’re not really quick enough to mix it up with other traffic, like you can on a scooter, and if you’re going to pootle along at 10-15mph on cycle paths then you may as well just pedal a normal bike and get some exercise in the process. Still, I was offered one for the weekend so I thought I’d give it a go.

Essentially it’s a regular town bike with a motor inside the front hub. The battery for the motor is where your bottle would usually sit (it’s about the same size) and the right hand handlebar grip doubles up as a throttle. There’s also a small control box sitting on the rear pannier rack and a bunch of wires connecting it all up. It still has front and rear mechs and shifters so can be pedaled like a regular bike without any assistance if you so wish.

Once on the go, it makes surprisingly rapid progress. The motor is limited to a maximum speed of 15mph which sounds slow but is actually plenty quick enough for buzzing about on cycle lanes and you can always use a bit of pedal power to boost that if you wish. I passed four other cyclists puffing away uphill on regular bikes on my 15 minute commute, like they were standing still. On the flat it’s up to speed in a few seconds, although there is a second of so of lag between twisting the throttle and the motor kicking in. On the uphills it struggles a little but will still get you up slowly without pedaling. However, it really only takes the lightest of effort on the pedals (imagine an exercise bike on low resistance) to assist the motor up hills without losing any speed at all.

I’ve now ridden the bike both to and from work and in both directions it took pretty much exactly the same amount of time to do the door to door journey of around 3 or 4 miles as it does in the car. Milton Keynes has an excellent network of cycle and foot paths that mean I can do the journey without touching any roads, however I’d feel fine riding this on the road through town in 30mph zones. Anything more than that and a scooter becomes more appropriate. Range is supposedly around 25 miles, but the battery unclips easily and can be recharged at your desk in a few hours. I believe this model had a 250W motor although there are bikes available with over double that power which would be better suited to hilly locations.

The two barriers for me that make riding to work difficult are secure storage and shower/changing facilities at work. The electric bike doesn’t solve the secure storage issue but does mean you can ride into work in a shirt and smart trousers without needing to shower or change when you get in, which is a big plus point over a regular bike. I don’t really have a need for one at the moment but if I had a commute of up to about 10 miles each way then I would seriously consider one of these as my daily transport. Bought through one of the employee tax free cycle schemes, it would work out pretty cheap. No road tax or insurance to pay and a daily charge only costs a few pence of electricity (I’m led to believe that it’s less than 10p).

Career change


A lot has happened since January. In February my employer announced a restructure, with some inevitable redundancies. At the end of March my time at Cranfield University came to an end, after nearly eleven years. During that time I gradually moved from IT to marketing, working as a sys admin, then web application developer and finally as online marketing manager, qualifying with the Chartered Instistute of Marketing only a couple of months ago.

Time for a change now though and a chance to pursue something that’s been on my mind for a few years. In September I begin my PGCE year to train to become a secondary maths teacher. Time to start revising my calculus.

Trail centre – Cwmcarn

My new year resolution of visiting some of the mountain bike trail centres around the UK is progressing nicely, last Sunday I took a drive over to South Wales to ride the Twrch trail at CwmCarn. It’s only a 30 minute drive past the Severn Bridge, so dead easy to get to for those living in the south and close enough for me to drive there and back in a day. Bar a few hundred metres of wider fire road, the Twrch trail is 18km of excellent windy singletrack. It starts with a pretty hefty climb that took about an hour with a few stops to take photos and catch breath. It’s an interesting climb though, winding alongside a river then zig zagging up the hill with plenty of roots and rock steps to keep you occupied. At the top is a freeride area with tabletops and berms aplenty, followed by about 45 minutes of mostly downhill or flat singletrack back to the carpark. The last couple of minutes of descent in particular is very smooth, very swoopy and very fast, which puts you on a nice adrenalin high when you come to a halt back at the car. Just time to grab sandwich and a drink before heading out for a second lap…
Definitely worth the effort for a visit, although next time I have a spare Sunday I might try Afan which is another half an hour or so along the M4 and has a wider selection of trails.

Bike skills coaching session

I attended a mountain bike coaching session last Friday with Tony Doyle of UK Bike Skills. The day was bought for me as a Christmas present last month and I’d been waiting for the date to come around with some anticipation. I’d heard good things about Tony’s courses but was also a tiny bit sceptical about what there was left to learn having been mountain biking for 20+ years.

I’m happy to say that any negative thoughts instantly evaporated once we got underway. Turns out there is plenty to learn and I picked up more in 5 hours on Friday than I have done in years. Particular focuses for me were cornering, smoothness through complex series of sections and a fear of my wheels leaving the ground. By the end of the day I was clearing tabletops, handling small drops with ease and flying through berms at what previously would have felt like impossible speeds. Swoopy singletrack is now more fun than it’s ever been.
Big thumbs up to Tony and UK Bike Skills.
