ケースは100円ショップで買ったものを使い、ありモノを組み合わせて安く済まそうとしましたが、意外と高くついてしょんぼりです。
まさか、ちゃんとした商品のUSBハブまで不良品だとは思いませんでした(^^;)

For the casing, I used one I bought at a ¥100 store, and I tried getting by cheaply by assembling stuff I already had, but I got dejected at how unexpectedly expensive it became. I'd never have thought that even the USB hub that I properly bought would be defective too. (^^;)
