stirrer

Last updated at Posted at 2017-04-23

stirrerを作った.
といっても, ファンに磁石を取り付けて回すだけ.
サーモ機能は面倒なので止めた.
可変抵抗を使って回転速度を調整できるようにはしている.

作成

可変抵抗は本当は200Ωくらいが良いかも. 実際に組んでみると200Ωくらいがfanが止まるかどうかの閾値っぽいので. ただし, 200Ωにした時, すでに回転している場合は慣性で回ります. 今回は手元に200Ωのちょうど良いのがなかったので500Ωにしました.

これらを配線するだけ.

GND(USB) ----------------------------┐
+5V(USB) --- 可変抵抗(最大500Ω) --- fan
