Board Etching Part 2

We talked about Board Etching Tools in part 1, in this part we will know how to design and make the board We will begin to design the tracks of any circuit with any graphic programs (Photoshop) or (Pointshop) or even the (Painter) and if the design is ready such as ready-made circuits, then all you need is to print the circle on the transparent paper. Note: You can directly draw on transparent paper or use the printer, thus...

Board Etching Part 1

This process of board etching and the work of the tracks is almost the same method used in factories to make parts of the radio and various electronic devices, but in a more professional way . This process is very important to the work of any electronic device and must be known by any inventor, and here we illustrate the easiest and the fastest and least expensive and are as follows : Tools needed for this process : Board needed in this process,...

Photoelectric Devices

Light Sensitive Devices : The light-sensitive elements to respond to changes that occur on light intensity and by changing the internal resistance (ie, less than the value of its resistance to increase the intensity of light), and is called light-resistance (photosensitive resistance) . Or generate electricity and increase the intensity of power to increase light intensity of photosensitive cells abd also called solar cells. Photosensitive Resistance...

Soldering Gun

Soldering Gun is an Adapter which lowers the voltage and raises the power, Connected to it's Secondary end copper wire (yellow copper ring) to be the soldering head. Soldering gun  is characterized by the following : 1- Quick access to the melting temperature of the soldering material - copper - tin so it is provided with trigger pressure during the welding process where the temperature reaches about 600 degrees Celsius within a few...
