HP vs IBM Laptop Engineering

I have just had reason to open up two ageing laptops to retrieve their CMOS batteries. Here is a quick rundown of what I had to do to get to them.

HP Compaq Evo N115


What I had to remove:
  • Battery
  • Hard disk
  • CD-ROM drive
  • LED cover
  • Keyboard
  • Screen
  • Heat dissipator
Total screws: 19 T-8 head screws of varying sizes, including 4 sprung screws that have to be removed and replaced in a specific order to prevent the heat sink breaking.

Time to disassemble: 20 mins
Time to reassemble: 10 mins

IBM Thinkpad R30


What I had to remove:
  • Keyboard
Total of 2 Philips head screws.

Time to disassemble: 1 minute
Time to reassemble: 1 minute

Conclusion

I think the conclusion is fairly obvious. The R30 is a "consumer" level laptop, so doesn't have the shear awesome build of the T or X series Thinkpads, and yet even for something as simple as this it runs rings around the other "big brand" laptop I have the misfortune of owning.

Thinkpad. Because anything else is just a world of pain.

Shooting the Enterprise

I was recently asked if I could help out providing an image for a magazine article about stress management. For reasons as yet undiscovered the requested image would be of the USS Enterprise flying through a storm in space. Unfortunately I didn't have a lot of time (just a couple of hours), but I did have a very nice model of the Enterprise D I could use to build the image around.

Thinking fast, I rigged up a rather slapdash rig consisting of a black reflector backdrop, an umbrella and stand from which dangled the model by a thread, and a couple of strobes. One light above, diffused, to provide the key light, and another, reflected and lower power, to fill some of the very dark shadows. It ended up all looking something like this:


Using a fast shutter, f/16 and cunning flash positioning I managed to keep the background black and give the model suitably textured lighting so it didn't have that flat, uniform, shadowless appearance of, well, a model. The narrow aperture obviously…

Another canal walk

The sun has started being a little more present lately, so some mornings are actually quite pleasant. On one such morning I decided to have a wander up the canal.


The clouds made everything look a bit Toy Story, and the low sun gave a lovely light and contrast to everything else.


Of course, it wasn't sunny everywhere. But even in the darker places, such as right underneath Leeds railway station, the sun had a go at peeking in.


Fairy Lights

Street lights at night can be very pretty. For someone who lives close to the centre of a large city, skirting round the edge of the town centre can provide a host of beautiful views at night.

One advantage to using a wide open lens when taking these pictures is the capture of bokeh, or creative blur. An extreme example is shown to your right; a mass of coloured circles that roughly represent the city they are part of.

A more subtle example, of course, is in the picture of the day at the top of this post. The lights cluster around the top of the leaves like fireflies, obviously part of a cityscape but at the same time abstract.

The extreme out of focus image is a blurred version of the picture on the left. A view over Sheffield from Pitsmoor, looking up Netherthorpe Road and up to the university. Even when the buildings are focussed (roughly; I'm still practicing) the lights take on the shape of the lens's aperture.

I try to incorporate some foreground focus when using blurre…
