时间:11月9号周日,下午13:00 -15:00.
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。
*** 电击危险,心脏虚弱者不建议参加本次工作坊!

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.

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。
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!
