Delete Protected system fonts (Win 7, Win10)

After installed required fonts for our newly installed Win10 computer.
I found the command prompt will show some weird chars for back slash.
After done some google search and poke around, I found a solution. One of the windows fonts cause the problem
usually I could just simply delete it from font fonder..however when I was trying to delete that one.
It shows an error msg saying that font is “system protected….etc”
to delete system protected font we could simply delete the key value from Registry.

HKEY_LOCAL_MACHINE → Software → Microsoft → Windows NT → CurrentVersion → Fonts –> “(Font Name)”

in my case font name will be : msgothic.ttc, MS Gothic & MS UI Gothic & MS PGothic (TrueType)

After deleting the reg key and then restart the computer the cmd prompt is back to normal now 🙂

Ferris wheel for fun

一直想要學Arduino, 加上想要自己手作一份禮物給VIP,所以才有做這個”摩天輪” project的想法。
其實我也不知道為什麼偏偏要選一個自己的弱項做這份禮物。從小不太喜歡做勞作,手不巧:( 也沒有電子的概念。
卻想要做一個會轉動又有RGB燈特效的摩天輪……一開始的陰影面積就超級大R~~~…。

著手這個計畫後才開始找很多資料,看Youtube,一步一步地學著做
有了一些想法後就開始買材料

八月九月就開始訂了一些材料,打算用冰棒木片和熱熔槍做摩天輪的骨架

八月時用arduino控制可程式的RGB LED燈(WS2812B 1m 60leds 5V 8A)
接好線路和把code upload到 Arduino後看到成果還滿順利的呈現,真的有種感動的感覺 哈哈哈哈哈哈

終於十月中某天晚上把結構做好,看過的朋友都還滿喜歡的。 話說轉動起來的感覺,真的還不錯 :):):)

今天晚上(2018-11-5)試試看用Arduino 來控制stepper motor 和同時控制RGB燈
改了一些CODE 整合起來再把power supply and data cable都接好,滿順利就達到想要的效果
還把一些線路做一個整理和焊接…第一次焊….才知道這麼難弄…哈
