A drive shaft from the hub connects to a helical gearbox, which turns a shaft, which then turns a magnet windmill generator. [citation needed] The electricity generated by the merry-go-round and all other play equipment in the EPI system is converted to direct current and used to charge a battery. A thirty-watt solar panel is also connect to ...

A roundabout (British English), merry-go-round (American English), or carousel (Australian English), is a piece of playground equipment, a flat disk, frequently about 2 to 3 metres (6 ft 7 in to 9 ft 10 in) in diameter, with bars on it that act as both hand-holds and something to lean against while riding.
An LED matrix or LED display is a large, low-resolution form of dot-matrix display, useful both for industrial and commercial information displays as well as for hobbyist human–machine interfaces. It consists of a 2-D diode matrix with their cathodes joined in rows and their anodes joined in columns (or vice versa).
Since the late 1990s, the most common technology used in new installations for variable message signs are LED displays. In recent years, some newer LED variable message signs have the ability to display colored text and graphics. Dot-matrix variable message signs are divided into three subgroups: character matrix, row matrix, and full matrix.
A 16×2-character dot-matrix display, where each character is made from a grid of 5×7 dots. A dot-matrix display is a low-cost electronic digital display device that displays information on machines such as clocks, watches, calculators, and many other devices requiring a simple alphanumeric (and/or graphic) display device of limited resolution.
Most injuries on public playground equipment were associated with climbing equipment (53%), swings (19%), and slides (17%). Falls to the surface was a contributing factor in 79% of all injuries. On home equipment, 81% were associated with falls. In 1995, playground-related injuries among children ages 14 and younger cost an estimated $1.2 ...

As with the blink element, marquee-tagged images or text are not always completely visible on rendered pages, making printing such pages an inefficient (if not impossible) task; typically multiple attempts are required to capture all text that could be displayed where messages ...
