充電用自作安定化電源2009年12月28日 23時40分02秒

ラジコンを走らせるために必要なものといえば電池です。
はりパパは京商R246のC-03という充電器を購入しました。で、これはDC用なので、車のバッテリーから充電するわけですが、やはり家で充電するときはいちいち車からっていうのはあまりにも不便。
で、安定化電源となるわけですが、これが買うと結構なお値段がするわけです。
どうしようかな、と思っていろいろ検索してみると、PC用のATXの電源を改造している人が結構いることが判明。
というわけで、早速はりパパも作ってみることにしました(^^)/
今、余っている電源はないので、仕事帰りにハードオフのジャンクコーナーを物色すると・・・
ありました!250Wの電源がなんと315円!!激安です。
今時のPCには250Wでは全く役に立ちませんが、充電用なら十分でしょう。後は、ジャンク品ということで、壊れていないことを祈りつつ早速改造開始です(*^_^*)

とはいえ改造といってもこれだけ


①コネクターの緑と黒のケーブルを切断してつなぐ(これで、PCの電源が入っている状態になるようで、電源だけで動くようになるようです)。

一応、この状態でコンセントにつないでみると・・・FANがちゃんと回りました(^^)/
どうやら315円ジャンク品電源は壊れてはいないようです。

②黄色のケーブルが12Vのようですので、はりパパはこれに家に転がっていた充電器の電源に差し込むコネクターと同じものを無理矢理つけました(^_^;)

で、あっさりと完成したのがこれ

ネットでは、電源によっては5Vにところに負荷をかけないと、10Vくらいしかこないことがあるなんて書き込みもあったのですが、テスターで計ったところ、この格安電源は問題なしのようで普通に12Vきていました。
これで、充電用安定化電源の完成です(^^)/
(余計なケーブルは、暇なときに切断してすっきりさせる予定です。めんどくさいのでしないかも・・・)

今後は、オレンジが3.3Vのようで、これを使ってモーターの慣らし用の電源がつくれるようなので、今度鰐口クリップを買ってきてつなげば完璧ですね。

というわけで、込み込み315円で安定化電源のできあがり~

え?電源を作る前に作るものがあるだろって?
その通り、先日購入したTA05 Ver.2の方はまだ手つかずです・・・(^_^;)
いや、年賀状とかいろいろあって忙しかったものですから・・・

*ちなみに、これは電源の正しい使い方ではもちろんありませんので、まねをして何かトラブルが起きてももちろん自己責任ということで。
