DIGI ZO Hyper 電源の単３電池化
標準では006P 9V電池を搭載するのだが、駆動時間が30分程度であり実用性がない。ACアダプタは仕様が室内に限定される為、外に持ち出す場合はオプションの単３バッテリーボックス付ストラップを購入するか、外付けバッテリーボックスを自作して使用するケースが多いと思われる。
長いこと、単３Ｘ６本の電池ボックスに1mくらいのケーブル＆006P用電池スナップを付けて使っていたのだが、バッテリーの置き場所が結構悩みの種だったりする。なんとか本体内臓にしたいものだ。
単３ｘ６本の内臓電池ボックスを買ってきては見たものの、（ボディは削るにしろ）どう考えても場所がない。
そこで、単３ｘ４本 ＆ 昇圧回路を組み込んでみることにする。
埋込電池ボックス
タカチ電機工業 ＬＤ－４Ｂ
購入先：千石電商
昇圧方DC-DCコンバータ
圧型ＤＣ／ＤＣコンバータ５～２５Ｖ可変出力電源モジュール組立キット
購入先：秋月電子
DIGI ZO Hyper用のＡＣアダプタを見ると
出力 8V 500mA
とある。
秋月の昇圧DC-DCコンバータキットの仕様は
・入力電圧範囲：2.3～5.5V
・出力電圧範囲：5～25V
本キットにおける最大出力電流の例
（リップル100mVp-p以下）
DC5V→DC9V…300mA
平滑用コンデンサ追加（キットに付属)で
DC5V→DC9V…750mA
とあり、平滑用コンデンサ追加すれば必要な出力は確保できそうである。
電池ボックス
ノミでちまちま削って組み込み。
裏のプラ板も、電池ボックスにあわせてカット。
昇圧回路は、006P電池ボックス内に収納。
やっぱりホモヒモ付きじゃないぞうさんは快適である♪

I absolutely love your blog and find the majority of your post's to be exactly I'm looking for. Does one offer guest writers to write content for yourself? I wouldn't mind writing a post or elaborating on most of the subjects you write regarding here. Again, awesome site!

It is much easier to download little pieces of a file from many servers than to download one big file from one single server. While this number of songs normally takes quite some time to be controlled by, it is fun to clean up your library from time to time, particularly if you enjoy the thrill of shuffle mode on your MP3 player.

Howdy! Do you know if they make any plugins to assist with Search Engine Optimization? I'm trying to get my blog to rank for some targeted keywords but I'm not seeing very good gains. If you know of any please share. Appreciate it!

This is what you should ask yourself before undergoing any surgery because it is your life and you should take a decision to have a 100 percent satisfaction. All of which contributes mostly to the improvement of body functions and partly to change one's appearance. There are very few negatives that can result of this type of surgery or leave one with a life threatening situation, but one just needs to be aware.

I have to thank you for the efforts you've put in penning this blog. I'm hoping to see the same high-grade blog posts from you later on as well. In truth, your creative writing abilities has motivated me to get my own website now ;)
