The Kahn Academy shows in a step-by-step process what’s inside a low-cost digital camera and why these cheap cameras are providing such a bad quality. Through this tutorial video each of the electronics components of a digital camera is shown and explained in detail. Components such as the CMOS chip, CPU as well as the digital memory and their purpose within the image capturing process are explained. A really useful video tutorial if you would like to know what’s inside your camera without opening your own 🙂
In this weeks episode of Massiomo Banzi’s official Arduino tutorials he shows us how to build a magic crystal ball by using his recently released Arduino Educational Starter Kit (The Arduino Starter Kit). Banzi’s electronic version of a Magic 8 Ball is built by using an LCD screen and a tilt sensor. Everytime the user is shaking the tilt sensor, the Magic 8 Ball will return a randomly generated answer.
In his latest Arduino tutorial video, Massimo Banzi explains how to control a motorized pinwheel without damaging your Arduino board. As DC motors can generate power spikes, that can damage electronic circuits, Massimo Banzi explains how to use a diode to overcome this issue. A DC motor works at a higher voltage than the Arduino. This means that it requires more current that an Arduino pin can provide. Within this video tutorial Massimo will also explain how to provide enough current to drive the DC motor.
This new Arduino Starter Kit offers an UNO board along with a huge collection of sensors and actuators to learn to experiment with the Arduino board from the scratch. The Arduino StarterKit was intended by it’s creators with the precise intent of learning how to use an Arduino and the base of electronic by discovering. The starter kit contains everything a beginner needs to build simple to complex electronic experiments without additional hardware costs.
As an additional benefit one of the initiators of the Arduino movement, Massimo Banzi, is giving stepwise video tutorials. These video sessions were started today with a brief session, how to setup your Arduino development environment and to get an introduction into your new Arduino educational development kit:
In this video, which is said to be one of the best micro multicopter / quadrocopter video tutorial on the web, a detailed description is given how to fully assemble a micro quadcopter within 10minutes. Despite the fact that i do not understand the speaker, the video is detailed enough to easily understand each assembly step. For those of you who prefer to buy an assembled, ready to play Quadcopter, check out the RobotStore gallery.
