One other attention-grabbing garbage-related story got here to the attention of the Tokyo Anaba editorial group this week. (be sure you verify our authentic put up about recycling in Japan). The Nikkan Kogyo Shimbun reported on January 22 that JX Nippon Mining and Metals, a resources company based mostly in Tokyo is in talks to kind a joint venture in Canada to salvage metals from circuit boards of used electronics to ship to Japan.
Quartz crystals: 32k , 16MHz – These are for precise clock sources for time-critical tasks like clocks or high-pace serial communication. Microcontrollers significantly can select between operating off a crystal and operating off their internal oscillators, but it’s the distinction between them being a couple of p.c correct, and them being 20ppm (0.002%) accurate. Particularly for the 32k crystal, the load capacitance may be necessary, so examine to see in case your software wants the 6pF … Read More
