Connected to a burglar alarm or fire alarm in the event of making phone calls playing voice messages. Controlled via DTMF actuators can operate on the spot.
In recent years we have introduced several telecontrols based on the SIM900 GSM module. We released schematics and code for a gate opener (that activates when receiveing a call from a given number), a GSM thermostat to manage the temperature of remote houses with simple text messages, a remote alarm control with DTMF and, last but not least, a remote alarm with I/O and controlled via calls or SMS.
Many of these tools send text messages or place phone calls in response to changes to the electrical inputs. In some cases, especially when the receiver is a human, nothing is like a voice that clearly yields you screaming “fire in progress!”, or”thieves in the house!” etc.

This post is the last of three and describes the software needed to build a web controlled home automation center. The previous two describes how to add a serial interface to a router and how to build a microprocessor lab board.
- Software for the router (OpenWrt)
- Software for the web server (html and CGI)
- Software for the lab board (PIC16F628 assembler)
- Protocol for serial communication between router and lab board
- Protocol for 433MHz radio (and html generation tools)

The SmartPulse™ family of DECT-based wireless sensors and base station devices from Dialog Semiconductor facilitate the creation of wireless sensor networks for home automation, security, health care and energy monitoring applications. DECT is an established technology that provides whole-house coverage, and SmartPulse with DECT ULE builds on this legacy. Its simple star networks can be used for a variety of home automation applications.
Systems running SmartPulse sensors can self-configure with a home’s DECT / DECT ULE hub or internet gateway, allowing connected systems to be managed over the web using a smartphone, laptop or tablet PC. Additionally, the sleep mode of DECT ULE enables a wide range of new wireless consumer products that run for up to 10 years on a single AAA battery pack. [via]

The microcontroller used is 0822 zilog encore! 8k series (soic,28pin) as shown on the figure. Is a programmable microcontroller, the functions used are the GPIO and the UART of the chip. GPIO is used on led indicators, and the UART is used for giving and reading AT COMMANDS to control the Bluetooth device.

This device transforms your PC into a powerful controller that you can use to program and automate machines, circuits, or just about anything you can imagine. Its flexible 29 I/O ports that you can configure to work ( bit by bit or in groups) as inputs or outputs makes it adaptable to a wide array of applications . Control of stepping motor system is unbelievably easy, thanks to its built-in Pulse Generator function. It even has encoder switch input functions, counting inputs, and port capture register. It is Visual Basic friendly, and more! [via]

This home automator used DMX (the popular theater lighting protocol) to automate all of the lights in his home. [via]
Why automate your lights?
Well, to be honest, most of my house is automated, so it seemed the obvious thing to do.
There are lots of benefits in automating parts of your house, lighting in particular just makes life easier, lights coming on when you walk into a room is better than switching them on yourself! ….and because they turn themselves on, they turn themselves off too, so you can’t forget!

The “Double Down” card dealer is a fully programmable automated card dealer that just like a real-life human dealer, will make sure nobody is cheating at your table. It has the ability to deal a card in two directions (left or right, dealer or player, etc) while at the same time moving linearly perpendicular to those directions (card stack 1, 2, 3, etc). Pretty cool project for the gambler / Maker in you.
