title: Accurate low-cost expanded-scale analog voltmeter with novel charge/discharge indication for monitoring single Lithium-ion cells

authors: Scott, Jonathan B.

abstract: This manuscript presents a very low-cost circuit using a PIC12F683 microcontroller and an LM285 bandgap voltage reference that provides an expanded-scale to an analog panel meter suitable for monitoring a single Lithium-ion battery. Charge or discharge of the cell is indicated by periodic twitches of the needle to the left or the right. The design is especially suitable for small devices subject to intermittant use or that recharge by power-harvesting. The design is open-source, with circuit, board layout, and source code provided.

title: American Mass Media and Sustainable Development

authors: Gunn, Alastair S.

subjects: media

abstract: The American mass media overwhelmingly promote a consumer culture, while paying scant attention to the effects this culture has on the environment. American film and television, especially, is reaching more and more people worldwide, thus promoting wasteful overconsumption on a global scale by encouraging people to abandon traditional, sustainable lifestyles and to aspire to an unsustainable consumerist lifestyle. Hollywood has produced many highly successful movies addressing major social issues, including environmental issues such as chemical pollution, nuclear radiation, and global warming, yet it fails to tie these concerns to the consumerist behaviour that is at the root of these problems. Although it may be too much to expect the American mass media to actively promote sustainable development, it is surely irresponsible to promote consumerism as if it had no adverse environmental consequences. Of course, ultimate power rests with the consumer, without whom there would be no audience to make moves for: but the decision about which movies to make, and where to release them, is in the hands of production companies. They have responsibilities not only to present generations but also to future ones.
