MOVE by Teptron teardown

MOVE by Teptron is a bluetooth controlled motor for your existing indoor blinds and shades. I backed their kickstarter campaige a while ago and received the reward unit last week. Nice.

1000円ちょっとでThetaリモコン Wio Node

リコーの全天球カメラ Theta S をいじる機会がありました。



Seeed Studio が出している Wio Nodeがいい感じです。Seeedから直接買うと$9.9。秋月で買っても1,100円







Wio NodeはもともとiPhoneアプリと連携して動かせるソフトが入っているようです。今回はそれは無視してkatsuya-sanのコードに書き換えます。

Seeed WikiにあったWio Nodeの回路図を見てみると、載っているuUSBコネクタは充電のみ対応。USB-シリアル変換ICも載ってないです。

Here it is. There is a switch hidden in the upper right corner.


Adding a blob of Sugru to the tray’s vertical wall should ensure to turn it on.

Typing text on the tiny keyboard feels like I’m back 10-20 years ago when I was playing around many PDAs.

My favorite PDA is HP200LX and I still miss its calculator application.

So I had to try installing MS-DOS version of HP200LX software (called CPACK200) via DOS BOX. And it runs!!!
