The SNAKY project goal is to build a robot moving around using the same crawling principle of a snake. This 'fun robot' is made with a set of thirteen articulated sections and the angle between each pairs of sections is driven by a servo motor (so twelve motors), simulating the muscles of the snake. Each section have wheels in order to limit the friction on the ground but these wheels are free-running only : Motors are undulating the snake, not turning directly the wheels.Snaky also includes an ultrasonic sensor providing ...

The Motorola Signal Booster enhances analog and digital picture quality, improves cable modem communication, and reduces lost data. It's fast and effortless way to make your signal strength up to 32 times more powerful. You can install it easily without need any tools. This device allows you to optimize multiple broadband devices in your home like televisions, cable set-top boxes, cable modems, VCRs, and digital radios - all from one convenient cable. Motorola Signal Booster is an alternative powerful booster to weak signal quality.

The goal of the project is to use a microcontroller to regulate some larger household like home thermostat. The project will control the space heater to keep environment temperature is maintained near a desired set point temperature. By using a USB interface, the project can be controlled using Windows application. The system uses PIC18F252 as main processor, DS1307 as Real-Time Clock, and Texas Instruments' TMP101 as temperature sensor.The PIC microcontroller stores all of the temperature change entries as a table in its EEPROM memory, and keeps track of which is ...

The Simple Wireless Security System is a security system that includes a ZigBee wireless door sensor and a PC interface. The door sensor mounts near the garage doors, and it detects the open/closed state using reed switches and magnets. The Atmel Attiny45 microcontroller fits in nicely with design because of its small size, low pin count, low cost, and it has a powerful serial interface feature that can be set up as a UART – the required interface for the ZigBee module. When a door opens or closes, the Attiny45 ...
