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) ·          Connecting wire ·          Power Supply ·          Ethernet cable ·          Android Phone

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

Line Follower Robot Our Line Follower Robot Line followers are one of the most prominent kinds of robots. They have existed for a very long time, however, the technologies used for building them have changed rapidly. Earlier, controller boards the size of bricks were used, but now they have shrunk and become tremendously powerful. Now, technology allows you to build a line follower in just under 10 minutes if you have the parts for it. So enjoy building this quick and easy line follower. Have fun with this DIY hacking tutorial!
