Excerpt from Popular Mechanics 1968 摘自 1968 年大众机械 Electrical fantasies with a Tesla coil 电气与幻想 特斯拉线圈 By HAROLD P. STRAND IT JUST SITS there spitting fire, like a fugitive from a mad scientists laboratory. The current its discharging-in a wicked,noisy 2-in. brush is of such a high frequency you cant measure it, but maybe it runs up to 40,000 volts! Feeling just a bit suicidal,you move a coin toward this geyser of fire. The greedy tentacles snatch toward it, but theres no shock. Even if you poked a finger into the brush, the current would just splash over your skin. 它只是坐在那里吐火，就像从一个疯狂科学家的实验室逃犯。目前它的放电，在一个邪恶的，嘈杂 2 英寸的刷的是如此高的频率，你无法衡量它，但也许它运行长达 40000 伏！感觉只是有点自杀的，你走向 这个间歇泉火灾的硬币。贪婪的触角朝抢夺它，但是没有冲击。即使你戳到手指刷入，目前也只是在溅到 你的皮肤。 Ever since Nikola Tesla invented a high-voltage, high frequency coil, science experimenters have been intrigued with their own variations on his coil. In Teslas time, high-frequency current was obtained with an induction coil as a primary source of power. Leyden jars served as capacitors, with a spark gap and the inductance of a second coil combining to form an oscillatory discharge of high frequency. With todays vacuum tubes and mica capacitors, we can make a much more efficient and safer coil. 自从尼古拉·特斯拉发明了一种高电压，高频线圈，科学实验者已经吸引了与自己的变化，他的线圈。 在特斯拉的时间，与该感应线圈作为电力的主要来源获得高频电流。莱顿广口瓶担任电容器，具有火花间 隙和第二线圈相结合，以形成高频率的振荡放电的电感。与今天的真空管和云母电容器，我们可以作出更 有效和更安全的线圈。 Tesla coil 特斯拉线圈 Spectacular fireworks include a ring of fire scribed by a wire pivoting on a phonograph needle attached to a terminal. A finer wire, attached directly to a coil, produces trumpet pinwheels, shown in the smaller photo. This article tells how you can create these fireworks. 壮观焰火包括火上附连到终端的留声机针刻划通过导线枢转的环。更细的导线，直接连接到线圈，产 生小号风车，在较小的照片示出。本文将告诉您如何创建这些烟花。 MATERIALS LIST 物料列表 1 811-A tube。1 个 811-A 管 1 Ceramic 4-pin socket with oval mounting flange。1 个陶瓷4 针插座，椭圆形安装法兰 1 9/16 ceramic plate cap。1 个 9/16 陶瓷板盖 1 25
