設計の知識が全くなくても、誰でもCADやレーザーカッターを使って簡単な機構を作ることができます。 今回は自宅の鍵をプログラムで開閉できる、ギアを使ったしくみを自分で制作したので、その過程をご紹介します。電子基板の部分を変えることで、こちらの動画のようにArduinoやスマートフォンで鍵を制御できます。 いきなり材料を切ってもうまくいかないので、まずはノギスでドアを採寸し、実物大の3Dデータを作ります。無料CADでも可能ですが小さな円が書けなかったりするので、慣れてきたら必要な時だけ月額制のAutodesk Fusion360を利用するのが効率的だと思います。 私の自宅の鍵はサムターンのカバー(図の青い部分)を手前に引くとドアとの間に数ミリ隙間ができたので、そこに板を挟み込んで全体を支える構造を考えました。

This instructable demonstrates and explains blooms, a unique type of sculpture I invented that animates when spun while lit by a strobe light (or captured by a video camera with a very fast shutter speed). Unlike a traditional 3D zoetrope, which is essentially a flip book of multiple objects, a bloom is a single coherent sculpture whose ability to be animated is intrinsic to its geometry. What you
This project describes the design of a very low budget 3D Printer that is mainly built out of recycled electronic components. The result is a small format printer for less than 100$. First of all, we learn how a generic CNC system works (by assembling and calibrating bearings, guides and threads) and then teach the machine to respond to g-code instructions. After that, we add a small plastic extru

arduinoを使った工作を幾つかやった後、倒立振子の作成を思い立ちました。今回の方針は次の2つです。 極力シンプルな構成自力で作る(webの先人に頼らない) 立たせるのにまるまる1週間以上かかりましたが、なんとか当初の方針を守りながら、上の写真の倒立ロボットを作りました(下の動画は動作のデモです)。 (*1)制御の方程式とジャイロのトラブルシュートはwebを参照しました (*2)動画では9V電池に代えてUSB出力のバッテリでarduinoに給電してます この倒立ロボットですが、構造、電装、スケッチ(プログラム)ともにとても簡素です。使用するセンサは1つだけ(200~400円)で、モータは普通に手に入る一番安いヤツでOKです。なのでarduinoでLEDを点滅させたことがあれば、あとは材料とプログラムさえ揃えば、半日もかからずに作ることができると思います。 それで作成後の感想ですが、倒立振

First off we need to connect the wire to car power adapter then to the battery. The battery is a 12V 1.3 ampHour battery The length of time the battery last very much depends on what you are doing with. But here is quick calculation If the raspberry pi uses 3 watts a hour then a 12v battery at 1.3 amp hours gives 15.6 watt hours So 15.6 divide by 3 gives you 5.3 hours. So the battery should last a
