I'm a 24-year old software engineer.

I have a very curious mind especially when it comes to how things work. I'm also enthusiastic for experiments and building things from scratch.

Some of my interests are programming, pixel art, comics, writing, rock music, and video games. I see code as a piece of art and try, as weird as it sounds, to make my masterpiece.

I like command lines and ASCII art. I find the old graphical user interfaces fascinating.

Here you will find some information on the HGG “Hydrogen Gas Gun”.

The HGG is basically a gas ionizer. It uses “laser” or light energy to help move the electrons away from the nucleus so that the high voltage can take over to dislodge the electrons from the gas atoms. There also needs to be a way to remove the free electrons from the gas and that is the purpose of the ECC or “electron extraction circuit.” These component’s working together will basically ionize the gas.

Why would one want to do this? Well in the case of the EPG there needs to be a way to attach a magnetizable atom to a noble gas.  An example of this would be to create iron gas atoms and get them to attach to unstable argon gas atoms to form a magnetizable gas lattice that can be used in the EPG.

When working with Hydrogen and Oxygen one would want to do this to destabilizing the gas atoms.  By extracting at least 4 electrons from the oxygen one can prevent the water module from forming during the thermal reaction of burning the gasses to release a much higher energy yield from the gas. This is how Stan was able to run his buggy on smaller amounts of H H O gas from water. He also was meter mixing other gases such as exhaust gases from the engine to adjust the burn rate of the H H O to equal that of gasoline. One can read this in his patents. Please see the patents page to download the patents.

about "node-red"

1. An App on my phone called MQTTitude MQTTitudesend my location to Node-Red Node-Red
2. The basic framework of my twitter message is then created in a function node
3. I take my location and query Forecast.io for the weather at that location
4. The returned data is then formatted in to my tweet message using further function nodes
5. The message is then sent to a Tweet node and tweeted for me

抓取網路資訊用RaspberryPi顯示

Node-Red是一個可視化的開發工具。它允許使用者通過組合多元化的視覺化元件來完成各式應用組合。這些視覺化元件可以是硬件設備(如：GPIO、智慧家庭周邊wemo)、Web API(如：WebSocket、HTTP、UDP)、功能函數(如：range)或者在線服務(如：twitter、mqtt)。

在Node-Red定義中，一個視覺化元件，就是一個node。一些nodes串接起來產生的應用，就是flow（流程）。基於網頁的開發環境，通過拖曳已定義的node到工作區並用線連接node創建流程來實現應用。

使用者通過點擊’Deploy’按鈕實現一鍵保存並執行。程序以JSON字符串的格式保存，方便用戶分享、修改。

使用Node-Red，可以輕鬆的建置屬於自己的專屬IFTTT應用 (If This Then That)，更可以打造屬於自己的IOT (Internet Of Thing)

比如：

– 定期檢查網頁資訊，發現特殊變化，發送MQTT給指定topic

– 偵測伺服器是否存在，若不存在，發送Mail給指定收件者

– 指定時間，鬧鐘提醒

– 建立網路聊天室

– 指定時間開啟或關閉電燈

派樂雲整理了幾個教學文件，希望可以經由這些教學文件，體驗Node-Red的廣闊應用。
