Homemade circuits using
Take apart a simple flashlight and reassemble parts to explore basic circuits in this home science activity. What materials make good conductors of electricity? Find out when you test household materials to "close" a homemade circuit. In this week's family-friendly science activity, kids learn about electricity by taking apart a small flashlight and using the parts to create a simple circuit. With a few wires that might be salvaged from a household junk drawer, kids create a working circuit that causes the flashlight bulb to light up. After successfully making a working circuit, kids create a break in the circuit by detaching one of the wires from the battery and then test different materials to see which ones can be used as conductors and which ones are insulators.

20 Best IC 741 based DIY Circuits
This project isn't something that uses a solar panel and uses the produced voltage for some electrical and electronics work. But this project shows how to make a solar panel yourself and what makes it reach maximum performance.
Here I'm showing how to make one simple solar panel using transistor. The chosen transistor is 2N in metallic TO-3 package. The below picture shows it's image. The small silicon chip inside the 2N is able to produce photovolatge when exposed to sunlight and in the cell the emitter becomes the positive terminal and the collector becomes the negative terminal. The cell produced open circuit voltage of 0. To light a bright white LED we need minimum mA current and the panel produced only 0.
The current depends on the intensity of sunlight and the cell should produce more current if it gets more exposure. The same cell produced near 0. So the silicon chip got times more sunlight and produces the huge current.

Homemade Circuit Projects
The information will greatly help you to proceed in a systematic way when making any of the following projects. In electronics, an LED circuit is probably the easiest of all to configure, yet still interesting to build and use. When these devices were first invented, the results were not so impressive. However, they advanced quickly and today we have them in all shapes, sizes and specs. The main feature of LEDs is their ability to produce significant illumination using trivial amounts of power.
Homemade Resistors
In this example, you will build a simple circuit using common household items to light up a LED bulb. A simple electric circuit is an electricity supply e. LED light to form a circle. When the circle is not complete, it is called an open circuit. The electrical equipment does not work in an open circuit. When the circle is complete, electric current can travel from one point of the circle around the loop back to the same point. It is called a closed circuit.

Following are 20 best IC based designs that could be implemented for any desired application as per the user preference. First we will learn a few general applications using IC , and then at the later sections we will be disussing some more complex and useful designs. In the first Figure. Figure 2 shows a non-inverting DC amplifier circuit using IC , with a set gain of around Just like the above, here too the gain could be modified by varying the value of Ro.

For me laser technique better then engrave, because no copper dust around working place. But laser must be powerful to avoid use chemical liquids. Conductive ink works, but doing very fine traces for small footptint IC, for example is impossible if you are using a pen. Also, the conductivity of the ink is poor. Ablating the copper with a laser works, but you really need a high power laser to make it work.

TL amplifier circuit and free PCB layout. If the images produced less suitable way you can look for it using the search box. This tiny circuit can deliver a whopping 18Watts into 8 Ohm speaker or 30W into a 4 Ohm speaker. Even though the output of the comparator is a digital representation of the input audio signal, it doesn't have the power to drive the load speaker. Here is an example compared to "efficiency" : An amplifier driven with Watts input develops Watts ouput to the antenna as radiated power.
