The 15 RMB Q-Meter.
I found this article about a very cheap DIY analog Q meter that anyone with a digital multimeter can build using readily available components.
The author spent around RMB 15 to get all the parts (excluding the cost of the digital multimeter and excluding the shipping cost).
This has been posted in the Chinese Crystal Radio Forum. I obtained the permission from the original author : bobby_jack to translate it to English and repost here. Thanks to google Translate. I also re-edited where google translate missed.
我用谷歌翻译的
15元Q-Meter。
我发现这篇文章是关于一种非常便宜的DIY模拟Q表,任何拥有数字万用表的人都可以使用随时可用的组件来构建。
作者花费了大约15元人民币来获得所有零件(不包括数字万用表的成本和运输成本)。
这已被张贴在中国水晶广播论坛上。 我获得了原始作者bobby_jack的许可,将其翻译为英语并在此处重新发布。 感谢谷歌翻译。 我还重新编辑了Google翻译遗漏的地方。 |
