Voice Controlled Lights using Raspberry Pi Voice controlled home application Today we are building a very useful project in which we can control the LED lights using our voice through Smart Phone. In this project, we will send voice commands from Smart Phone to Raspberry Pi using Bluetooth Module and Raspberry Pi will receive that transmitted signal wirelessly and will perform respective task over the hardware. We can replace the LEDs with the AC home appliances using relays and can build a Voice Controlled Home Automation Project. Components Used: ·          Raspberry Pi 3 (any model shall work) ·          Bluetooth Module HC-06 ·          Bread board ·          100 ohm Resistors (3) ·          LED’s (blue, red, green) ·       ...

Automated Portable Hammering Machine Hammering is the most widely used industrial as well as construction activity. Hammering or screws, metal sheets, parts etc requires a lot of time and effort. So here we propose an automated hammering system that allows for fully automatic hammering process. This allows for accurate, fast and automated hammering wherever and whenever needed using a 12V battery. The person just needs to insert workpeice and start the hammering machine. This machine can be used for automatic hammering work as and when needed. We here use a dc motor in order to move the hammer. The DC motor consists of a pulley attached to it which is connected to a larger pulley for efficient power transfer and to increase torque. This large pulley is connected to a shaft that has a connecting rod attached to it. This rod is used to achieve lateral motion from the spinning shaft. We now connect the other end of hammer to this connecting rod through a mid swinging arrangement i...

Soldier Health & Position Tracking System The soldier Health and Position Tracking System allows military to track the current GPS position of soldier and also checks the health status including body temperature and heartbeats of soldier. The System also consists extra feature with the help of that soldier can ask for help manually or send a distress signal to military if he is in need. The GPS modem sends the latitude and longitude position with link pattern with the help of that military can track the current position of the soldier. The system is very helpful for getting health status information of soldier and providing them instant help. The nation’s security is monitored and kept by army, navy and air-force. The important and vital role is of soldiers who sacrifice their life for their country. There are many concerns regarding the safety of the soldier. Soldiers entering the enemy lines often lose their lives due to lack of connectivity, it is very vital fo...
