3dpBurner. An Open Source 3D printed laser cutter/engraver.

3dpBurner is an open source laser cutter/engraver CNC machine. It is created with the same RepRap concept, by using 3D printed parts and some easy to find "vitamins" (non printed hardware). I tried to design as cheap as possible, by using comon electronics and a "low power" laser (a laser diode). The X/Y working area is fully customisable by simply cutting the rods to desired length. The max object height f ...

Oscillators: How to generate a precise clock source

our modern era, digital logic has become the core of all the electronics circuits either in the form of an FPGA, microcontroller, microprocessor, or discreet logic. Digital systems use many components that must be interconnected to perform the required functions.  The vital element for proper operation of such a digital system is a CLOCK signal that enables all these digital components to communicate and es ...

Open Source Home Automation Project using Arduino UNO + Ethernet Shield

This is Open Source Home Automation Project based on Arduino Uno and Arduino Wiznet based Ethernet shield. How Does it Work The main brain for this project is Arduino UNO Board along with Arduino Ethernet Shield to give it a wireless connectivity.Arduino runs a code to control a Relay board according to the input and also serves a web page through which respective output to the relay board can be controlled ...
