最后写了个2加个圆点是什么意思？

每个红色发光二极管压降2v 左右
6个串联的 9v的电池怎么可能全部点亮哪

如何变的这个戏法呢

我相信是真的, 原帖人 Fredzislaw100 发的帖. 往纲上查找一下就可
以找到他的资料.

这个玩意利用高频震盪及微电子零件作道具.

A month ago, we saw a marvelous demonstration of troll physics from YouTube user [Fredzislaw100]. In his video, we saw a circuit of three switches and three LEDs wired in series and but not acting like the should. A lot of the comments for this post elicited reasonable explanations like modifying the battery or pure camera wizardry via After Effects. Thankfully, [Alan] stepped in and showed us how it was done. The solution uses two AC power sources with diodes in two of the switches and LEDs and inductors in the third pair. [Alan]‘s build was rather large compared to the original video, so we were wondering how this circuit could be made invisible.

[Fredzislaw100] just posted a video on how he did it. Like [Alan]‘s build, it uses two AC power sources, diodes, and inductors. In contrast to every single guess about where the circuit is hidden, the majority of the build is inside the battery connector. [Fredzislaw] did some amazing work hiding a 74LV132 quad NAND Schmitt trigger inside the battery connector. The diodes were easily hidden on LEDs 1 and 3 with some red nail polish, but we’re amazed by the inductor built into the LED seen in the title pic.

So there you go. With a ton of electronics know-how and an extremely steady hand (and a microscope), you too can build your own troll circuit. Check out the video after the break.

英文不好，不敢乱翻译，请大家自己看。

Last month we caught wind of an impressive display of troll physics. [Fredzislaw100] out of Poland posted a video of a circuit that should not exist. As expected, the comments in our coverage blew up with 200 posts. About half the commenters called a little Adobe After Effects trickery, while the other half offered up an electrical explanation. We’re happy to report that [Alan] successfully reproduced the impossible circuit and earned an incredible amount of electronic wizard points in the process.

[Alan]‘s solution uses low-frequency AC with the first two LEDs. The first LED points forwards and the second diode is reversed. Easy enough. For the third LED, [Alan] used high frequency AC with an inductor wired in parallel with the LED and the third switch. For those of you keeping track, that means [Fredzislaw100] put an SMD diode in two LEDs and two switches and an inductor in one LED and one switch.

[Alan]‘s build is just a proof of concept – It’s still on a breadboard and doesn’t have the incredible level of polish that [Fredzislaw100]‘s has. That being said, [Alan]‘s build is most likely very similar given the small glitch at 2:05 in the original video.

Check out [Alan]‘s build video below, and for an added treat check out his 2011 Advent Calendar of Circuits.

只能拍成视频后期加工，这个电路能实现如此功能（按他的电路图），人类将进入一个新的时代。

一个月前,我们看到一个神奇的示范的巨魔物理学从YouTube用户[Fredzislaw100]。在他的视频中,我们看到一个电路开关和三个led的三个系列,但不连接代理像应该。很多评论这篇文章引发了合理解释像修改电池或纯相机魔法通过后效果。值得庆幸的是,[Alan]介入,向我们展示它是如何完成的。这个解决方案使用两个AC电源,二极管在两个开关、led和电感器
上个月我们抓住了风的令人印象深刻的巨魔物理学。[Fredzislaw100]从波兰贴出了一段视频,一个电路,不应该存在。正如预期的那样,在我们报道的评论与200年炸毁了帖子。大约一半的评论者称为小Adobe After Effects的诡计,而另一半则提供了一个电的解释。我们很高兴地说,[Alan]成功地再现了不可能的电路,获得一个难以置信的电子向导分过程。

如果能实现的话只有1种可能，LED不是普通的，里面带有译码电路，开关也带有编码电路，有种LED里面加有IC，可以使3种颜色按不同的方式闪亮，我想加个译码ic是绝对有可能，注意视频里面他都是按顺序焊接LED和开关的，如果顺序不对的话开关就不能正好和灯的位置对应上

首先，人家直说，这是一个魔术，呵呵，相比某些大师的行径。
英文里边只公布了三个灯和三个开关的情况。（人家魔术师没有全公开的义务）
大概意思就是，你看到的9V积层电池是作假的，内部其实是有一个振荡电路（数字电路搭成的），所以“电池”的输出是交流电。
关键就在这个交流电上。
开关和灯泡都并联了二极管，贴片的元件很小看不见，分别利用交流电的正半周和负半周来点亮对应开关的灯泡。还提到有电感，没看懂。
（我说的太简化了，有兴趣的，还是自己盯一下洋文。）
