How big do my motors need to be?

hi, i need 2 motors push 750g - 1kg of weight. i have tried these motors: https://www.amazon.co.uk/gp/product/b01ezqcjty/ref=oh_aui_detailpage_o04_s00?ie=utf8&psc=1 and slowed down/ increased torque gearbox gear ratio 8:1. this hasn't been enough how bigger motors need be? you need measure force required move weight -- use luggage scale or similar. then convert torque, can compare motor specifications. here introduction force , torque . discussion on converting torque push .

Using the INA226 to measure current up to 80A from 42V battery

hello, i'd use ina226: datasheet: http://www.ti.com/lit/ds/symlink/ina226.pdf along 10 milli ohm shunt resistor , current of upto 80a in order monitor high current off battery in data sheet says "senses bus voltages 0 v 36 v" what meaning of that? can measure high current 10mohm shunt resistor ic (max 0.8v voltage drop on shunt)? or mean measure current of upto 3600a 10mohm resistor? quote from: mikelemon on aug 06, 2017, 12:28 pm hello, i'd use ina226: datasheet: http://www.ti.com/lit/ds/symlink/ina226.pdf along 10 milli ohm shunt resistor , current of upto 80a in order monitor high current off battery in data sheet says "senses bus voltages 0 v 36 v" what meaning of that? can measure high current 10mohm shunt resistor ic (max 0.8v voltage drop on shunt)? or mean measure current of upto 3600a 10mohm resistor? another question comes after little bit of research. necessary  connect v-bus of battery ina226? ...

DVDのノイズ

編集初心者です。使用PCはVaioRX−63 ペンティアム4 1.7G メモリー1GBでDVGateでキャプチャーしPremiereLEで編集 それをファイルに書き出しておりますがオープニング等BGMやトランジョションタイトルを多用している部分で画像の劣化が目立ちます。更にこれをDVDitでDVDに書き込みますと加えて黒 い細かい雨のようなノイズが発生します。「多用」が原因なのでしょうか?より劣化なくDVDに書き込む方法をご教授下さい。 premiereleはaviキャプチャだと思いますが、ファイルへの書きだし、つまりエンコーダは何をお使いですか?またキャプチャ画像置き場と書き出し用のhddはos・アプリとは異なる ドライブを持っていますか?dtvを効率良く行うには、 C:osとアプリと仮想メモリ領域 30-60gb D:dvd rwドライブ E:キャプチャドライブ 80gb-120gb F:書きだし専用ドライブ 大きいほど良い のhdd3台i以上の体勢があるとエラーが少ないです。 CとDはプライマリのマスタ・スレーブ、EとFはセカンダリのマスタ・スレーブに接続すると良いでしょう。こうしたストレージ対応が出来ない筐体では、ノイズが少なく、出来の良いdtvは難し いかもしれませんね。 dvdへの書き出しは、単なる動画の保存ならmpg2へエンコードして、dvd rwのライティングソフトで焼けば良いですが、エンコーダの性能が低いと画像の劣化が酷くなり、また6mbpsを切る画質でdvd video作成のためにオーサリングすると、さらに画質を劣化させる事があります。 とりあえずaviからmpg2に書き出すなら、novacのcce basicが簡単で結構綺麗です。価格もダウロード版は¥6kくらいです。マシンパワーがあれば、実再生時間程度で書き出せる所も魅力的です。6.0leならプラグインで使えるはずです。詳 しくは以下でお問い合せください。 http://www.novac.co.jp/release/release030214.html cce basicが書き出したmpg2はそのままmedia playerなどで再生可能ですし、dvd movie wiriterを使えば、簡単にチャプタが付いたdvd videoも作成可能です。 黒い雨の...
