View topic - [Help] Reverse engineering an Orvibo AllOne IR Blaster. Unitek Global Limited. Introduction Traditionally, "home automation" is a luxury product for premium class customers.
Every equipment and appliances had to be redesigned for installing home automation system. However, this remote controller hub, Broadlink RM Pro allows you to design your own home automation theme with traditional appliances. RM Pro can replace all traditional controller controlling RF and IR appliances. You can just use your smartphone to control all appliances anywhere at any time once you can access the internet. In coordinate with the app “e-Control”, not only control the power on / off of appliances, you can preset scheduling, theme, etc. Features Remotely control home appliances – from anywhere through mobile internet Infrared / 433, 315MHZ RF appliances support IOS, Android support – Free apps on IOS and Android platforms.

NodeMCU API Instruction version 0.9.5 build 2015-02-13 node module.
NodeMcu Lua WIFI (Module basé sur le ESP8266) 10.71€ @ Aliexpress. Ce module peut fonctionner comme un serveur avec 3.3v, assez impressionnant pour le prix surtout avec la promo.
Il fait partie du monde de l'arduino/raspberry donc ne vous attendez pas à pouvoir mettre un serveur minecraft dessus. Il y a 10 Gpio qui peuvent être utilisés pour prendre des donnés, pour la température par exemple et envoyer directement sur internet sans passer par un raspberry ou câble. On peut aussi lui transmettre des ordres par internet, par exemple pour activer un relais etc. Ce qui veut dire qu'il peut être mis presque n’importe ou et le contrôler bien plus facilement que les autres modules sans fils comme le RF(nrf24l01 par ex), par ailleurs la distance de "la communication" est vraiment bonne, les plus fou ont réussi à faire communiquer ce module avec un routeur à une distance d'environ 3km, mais avec un routeur classique le signal devrait être reçu dans (presque) tout la maison et surement autour aussi. 2,90€ le Esp8266 ESP-12: 5€ les deux:
An open-source firmware based on ESP8266 wifi-soc. Google Translate. Thomas Meghe. Bored of your favorite Twitter client ?
No problem, here’s the solution ! In this post we are going to explain how to control the awesome WowWee Robosapien with a wirelessly connected Arduino to trigger some actions on the robot through a specific Twitter hashtag. Goals Hack the Robosapien with ArduinoDeploy an app on Heroku allowing it to be available 24/24 Use the Twitter streaming API to watch new tweets posted on the #tweetosapien hashtag Use websockets with Pusher to send events to Arduino Robosapien hack Hardware The Robosapien is well engineered and quite easy to hack.
Unscrew the 4 screws at the back of the Robosapien (2 behind the shoulders and 2 behind the hips) to access the PCB.Spot the head connector at the bottom of the PCB (above picture)Remove the ribbons to disassemble the PCB.Spot the black and white wires on the head connector. Arduino The original code on which is based the program to fake the remote and send data to Arduino is available on this page. #include <SPI.h> Technology Instructables. Arduino Automatic Watering System For Plants Sprinkler. Last month, Elecrow have left from the original office and moved to a new office.
We will miss our original office where we worked so hard for more than two years, we will miss everything here, the desks, the windows, and those potted plants, that we cared for more than two years with our neighbor. Our neighbor, a design team, led by a man named Kimi, we had so many memories together in the difficult early days. Together we planted some potted plants in the balcony, to help us release when tired after a whole day hard working. But as we leave, Kimi team are so careless and they often go out for some shows, we all worry about that these plants will be thirsty as we leave. So, We decided to design an automatic watering system to ensure that these plants are still alive when we come back here the next time. I have recorded a video for reference: First, we prepared the following modules(all parts can find in www.elecrow.com): 1. 2. Add Radio to a Syma S107 IR Helicopter (or any other IR device)
Remote controlled helicopters and other toys have become incredibly advanced for a very low price, this is partially thanks to the huge mobile device market, which has pushed technology in small high energy batteries forward and ramped up production of micro motors.
A stable micro helicopter which can fly for 5 minutes on a charge can now be gotten for $20 or less, and there are many interesting variants like UFOs and mini quadrocopters. The main downside of these devices is that they use infrared (IR) remote control rather than radio, this is the same technology used in television remote controls. It works by pulsing an IR LED light, which is invisible to the human eye, and the device being controlled detects the pulses using an IR phototransistor, which changes its resistance when hit with IR light. Because these devices are light dependent, they require a clear line of sight between the transmitting LED and the receiver.
