About 4ndreas. Sans titre. Open platform The Crazyflie platform is an open development platform consisting of open hardware and open source firmware/software.
The reason for making it open is that we want users to be able to hack, modify, experiment and learn from our platform. The projects are developed using only open tools. Project logs. Getting the car street legal.
This is for sure the least exciting & possibly most difficult part of our car build. CNC Cookbook: Astronomical Clock. Notes on Constructing an Orrery / Antikythera Mechanism I've always had a great interest in Astronomy, and I read with great interest recent articles about the Antikythera Mechanism, which was apparently an ancient orrery or simulator of motions of the heavenly bodies.
The machine, which was constructed circa 80 BC, could represent the motions of most heavenly bodies known in its time using a clockwork consisting of 37 gears. Differential Gear Mechanism Was Way Ahead of Its Time... The front dial would show the progression of the Sun and Moon through the Zodiac according to the ancient Egyptian calendar. The lower back dial gives the Metonic cycle, the Synodic cycle, and the Lunar year of 12 Synodic months. Front and Back of a Reconstructed Model of the Antykthera Mechanism. Végétarisme.

Matrix & Sprite Arduino Libraries, for a many-LED display! The Matrix library allows you to control a large number of LEDs, with easy-to-use (but expensive) MAX7219 chips.
Sprite is used with Matrix, to draw shapes. Download: Matrix_Sprite.zip (updated for Arduino 1.0 & later) Matrix and Sprite have been tested with Teensy 2.0, Teensy++ 2.0 and Teensy 3.0. Hardware Requirements. Fabriquer une horloge à LED sur le principe du jeu Pong. 8x8 LED RGB Matrix (SKU:DFR0202) Blog. The Crazyflie 2.0 supports two types of radio protocols out of the box: ESB (Enhanced ShockBurst) for Crazyradio/Crazyradio PA USB dongle compatibility and Bluetooth LE for mobile devices.

Learning Python With Tron Radio. [5 Volt Junkie] has built his share of Arduino projects, but never anything with Python, and certainly never anything with a GUI. After listening to Internet radio one day, a new idea for a project was born: a Raspberry Pi with a small touchscreen display for a UI and displaying soma.fm tracks. It’s finally finished, and it’s a great introduction to Python, Pygame, and driving tiny little displays with the Pi.
Playing soma.fm streams was handled by mpd and mpc, while the task of driving a 2.8″ TFT LCD was handled by the fbtft Linux framebuffer driver. 8x8 LED RGB Matrix (SKU:DFR0202) Open source Nest-alike learning thermostat. About Earlier this week, Google bought Nest, a connected devices company, for $3.2 billion. Real Time Clock: DS1307. Voici maintenant quelques temps que je possède ma carte Arduino et je commence a vouloir expérimenter d'autres choses que faire clignoter une led ou lire des valeurs analogiques sur une liaison série. C'est pour ça que j'ai commandé le DS1307 qui est une Horloge temps réel commandé par I2C. C'est d'ailleurs un très bon moyen pour moi d'apprendre à utiliser le bus I2C que je connais pas encore. Je vais donc rassembler ici, toutes les infos et démarches faites pour faire fonctionner ce fameux composant. le Datasheet Adresse I2C (7bits) du DS1307 :
Compteurs eau et gaz à impulsion sur IPX800. Dans les grands principes de la domotique, un élément essentiel est selon moi la maîtrise du coût des énergies de l’habitation. Jusqu’à présent équipé d’un compteur OWL CM 119 (approximation intéressante des dépenses électriques), il me semblait primordial de suivre également ma conso d’eau et d’électricité. Ball-sculpture - Snille.net. The Ball Sculpture First off, as the base of the project I created a set of rules. I had these rules in mind when I built the whole sculpture.
