Creating wooden laminates in your shop

AS A HOMEBUILDER WORKING on a Pietenpol Air Camper, I’ve had to contemplate a fair amount of woodwork. While some of the solutions are fairly straightforward and easy to resolve, others have taken a bit of research and have occasionally required me to learn a new technique, which is one of the best things about home building—the learning. For those familiar with the Air Camper, you know that many choose to construct the center struts (or cabane struts) out of wood. These vary in type from solid planks of walnut or Douglas fir to

Using Journeys to Differentiate

Identifying the journeys that matter most can be beneficial even when companies don’t have a nagging customer service problem – the effort can help them find a competitive differentiator. One car rental agency wanted to improve its already good service and distinguish itself from its competitors in light of the increasingly commoditized nature of the industry. Its investigation into what mattered to customers highlighted the airport pickup, a journey that might take less than an hour but that crossed a half-dozen or more touchpoints. The most important aspect was the end-to-end speed of service, from bus to rental counter to

The Universal Timer

The timing of events and processes is becoming an ever increasing necessity in virtually every automation task, not only in the industrial sphere but even in the domestic sphere. No wonder timers arc often referred to as the first step towards automation.

This universal timer offers an ultrawide timing range which can be set with pin point precision anywhere from one-tenth of a second to hundred hours! Dispensing with the ever-problematic analogue dial, this timer is built around common CMOS chips, and features autolatch facility plus such a low current consumption (hat most multimeters would fail to detect it. All

Stormy compositions

Photographer and Photoshop Elements artist Steve Jagger reveals the core techniques behind his image ‘Guiding.

Steve Jagger has an eye for good images, and he calls upon his experience as a photographer to capture all the stock photos himself. He then carefully pieces everything together using the tools and adjustments available in Photoshop Elements.

‘Guiding Light’ was composed using selections and layering techniques, which are shown in the steps below. What makes this image stand out the most is Jagger’s application of Blur filters and lighting effects, all of which make you feel as though you’re really part of scene.

Adrian Marshall decided that he’d need a very convincing scale model to sell his latest idea. The British designer of factory robots was to meet the board of directors of a large food company, who wanted an industrial robot that could move ten arms independently and burn a picture of the Rugrats cartoon characters on pancakes randomly placed around a moving skillet. It had to be done in under 0.8 seconds in a hot industrial kitchen. Of course, he used the only prototyping material suitable for such a tough job: Lego.

«I always use Lego to present to customers.» says

Easily compress shots using JPEGmini.

Make Large files smaller without losing any quality at all.

The size of an image refers to how large it is in dimension, as well as how much information it has.

Digital images are made up of thousands of tiny dots, otherwise known as pixels. The more pixels you have, the better the quality of the image and the bigger its size. If you’re working with images in print, it’s vital to use pictures that are of extremely high quality. When using them on the web, for example uploading and sharing images via Flickr or Facebook, or even sending an

Blog Better with Markdown

Create richly formatted content without typing a single line of HTML

The iPad’s a great text-editing platform, but when it comes to applying complex formatting, changing styles, and editing HTML code, things start to get a bit too complicated for the tablet. Even with an external keyboard attached, which gives easier access to the chevrons and digits used in HTML, you still spend more time than you should reaching forward to tap the screen to add a non-standard character.

Fortunately, there’s a better way. Markdown lets you apply complex formatting using common characters like [, ], tt, -, and *.

Birds In Flight

Photographing flying birds is more about the preparation you put into making the picture happen than sheer luck. A combination of using the ideal settings while anticipating the right moment is essential to get a perfect shot like this.

I switched my camera to the Manual mode for a fast shutter speed and narrow aperture while setting up for this action shot. If you are using a compact camera, you can even use the Sports mode for similar settings. Instead of simply using a zoom lens from a single location, I decided to move closer to the birds. I used

Let the AP team answer your photographic queries

Q l am the very proud, possibly misguided owner of a couple of Leica cameras — an M6 and an MS. Is there any snag in using Leica R lenses? Compared to M lenses, there seem to be far more available second-hand and they are generally much cheaper. Adapters are easy enough to source as well. Dave Hasted


Whenever you start talking about using lenses from one system on a camera from another system, you’re talking about compromise: the fact is that ‘lens A’ was designed to be used with ‘camera
