動手做，動腦做，手腦並用的做。
用手寫，用心寫，得手應心的寫。

Do it yourself
Do it yourself, also known as DIY, is the method of building, modifying, or repairing things without the direct aid of experts or professionals. Academic research describes DIY as behaviors where “individuals engage raw and semi-raw materials and component parts to produce, transform, or reconstruct material possessions, including those drawn from the natural environment (e.g. landscaping)”.[1] DIY behavior can be triggered by various motivations previously categorized as marketplace motivations (economic benefits, lack of product availability, lack of product quality, need for customization), and identity enhancement (craftsmanship, empowerment, community seeking, uniqueness).[2]
The term “do-it-yourself” has been associated with consumers since at least 1912 primarily in the domain of home improvement and maintenance activities.[3] The phrase “do it yourself” had come into common usage (in standard English) by the 1950s,[4] in reference to the emergence of a trend of people undertaking home improvement and various other small craft and construction projects as both a creative-recreational and cost-saving activity.
Subsequently, the term DIY has taken on a broader meaning that covers a wide range of skill sets. DIY is associated with the international alternative rock, punk rock, and indie rock music scenes; indymedia networks, pirate radio stations, and the zine community. In this context, DIY is related to the Arts and Crafts movement, in that it offers an alternative to modern consumer culture‘s emphasis on relying on others to satisfy needs. The abbreviation DIY is also widely used in the military as a way to teach commanders or other types of units to take responsibility, so that they’d be able to do things themselves just as a preparation for their own future.

Astrophotography with the camera board
Cristos Vasilas from Dash One, a lover of astronomy and electronics, has been trying out the Raspberry Pi camera board as an astrophotography tool. He’s captured some amazingly sharp, short video of the moon, and of Saturn, rings clearly visible, swinging across the sky.
Cristos used foam packing material to attach the camera board to the eyepiece of his telescope, and mounted the Pi on the barrel of the telescope with velcro.
Cristos says he has more work to do on exposure, gain, contrast and so on, and we hope he’ll be posting the results on his blog.
Updated to add: Cristos took some more video and stills of Saturn, this time with a 6mm lens, making the pictures even larger. They’re amazing – you can very clearly see the gap in the rings, and the shadow cast on the planet by the rings. Check them out.
We’ve found that there’s enormous potential in bringing down the cost of amateur photography – of all kinds – as a hobby with the Pi, whether or not you’re using the camera board. Check out these earlier posts if you’re interested in finding out more.
