用高压电弧制做扬声器,就是利用高压音频电流电离空气,空气受热膨胀、震荡发声。有人将这个装置放到众筹平台KS上,小火了一把,记得是99美金一个,还是套件,需要自己组装。今天我们就用特斯拉线圈“拉弧”做的音乐播放器!
原理: 使用传统的TL494电源芯片,驱动IRFP250场效应管半桥,推动高压包产生高压电弧放电。输入到驱动电路音频信号通过控制RL494输出波形的死去时间来控制电弧的粗细。由于其变化频率很高,虽然肉眼观察不到电弧的瞬间粗细变化,但是由于其粗细变化足以影响到周围的空气并使之振动,并产生与输入信号相同的声波. 虽然看似简单,但是没有电子知识还是不那么容易的哦。

Time: 13:00 – 15:00 Sunday, Nov. 9th.
Fee: 300rmb; 250rmb for xinchejian members. Price includes all materials needed.
Are you tired of those old black speakers that only just make sounds? Maybe sound reactive lights are just not enough to impress you? How about a Plasma Speaker?
A plasma speaker is a device that generates an high voltage electrical arc that makes purple light and music! Without any speakers or any moving parts! Sounds too good to be true? Well, you’re wrong, the high voltage arc really does ‘sing’ by vibrating in the air. (Of course, you will need to give the device musical audio for it to work.)
*** Do NOT even attempt to build one if you have heart problems or weak heart or wearing a pacemaker, because one little shock from this thing can put you out.

时间:11月16号周日,下午14:00 - 15:30.
费用:150元(会员)或200元(非会员),包括整套水培种植器具,手动浇水器,营养液
简介:
如果您对如何栽种植物毫无头绪,也不了解什么是水培,那么这个工作坊就是为您准备的。
工作坊会全面讲解植物栽种的基础技能,以及如何利用简单水培系统(手动浇灌)低成本种植可食用植物并进行维护。
除了获得这些理论知识,参加者还将亲自动手组装自己的基础水培系统,并学习如何将幼苗移植进系统。
短短的时间,参加者就可收获一组鲜活植物和亲手搭建的整套基础水培系统!
只欠一点耐心及动力,下一位植物达人就是你!

Time: 14:00 – 15:30 Sunday, Nov. 16th.
Fee: 150 RMB (for xinchejian members) and 200 RMB (non xinchejian members, including hand watered hydroponic system, watering bottle/spray, nutrients。
Description:
If you know nothing about growing plants or what hydroponics is, this workshop is for you. This workshop will cover basic plant growing and hydroponic techniques that will allow you to understand and maintain one of the most basic hydroponic system types (hand watered container) with some of the lowest maintenance and resilient edible plants available.
You will also learn how to assemble a basic hand watered container hydroponic system, and how to transplant seedlings into the system. At the end of the workshop, you will leave with a functioning hydroponic system with live plants and the knowledge to keep them alive. After that, all you will need for success is patience and motivation!
