Oct 01, 2018· How to Design a Simple Antenna. This article will show you how to build a monopoly for any use you see fit. Find out what frequency you want (for Wi-Fi you are using 2.45GHz = 2,450,000,000Hz). This is needed because this determines the...
Parts: - 555 - 47 kΩ resistor - two 2μ2 F capacitor - PCB - 9 V battery, switch, battery cable and some wires - buzzer - 100 m of copper wire, 0,2 mm in diameter - gaffer tape and wood glue Instead of buzzer you can use 10 μF capacitor and speaker (8 Ω impendence). Tools: - breadboard and wires - pliers, tweezers, pliers for making holes - soldering iron and soldering wire - sharp knife ...
Radar has made much of modern life possible, and if you're into building your own electronics building one is a fun and useful project. Watch this video for instructions on how to build your own simple radar out of cheap spare parts from a satellite dish or a toy radar gun.
In radio frequency (RF) terminology, the Very High Frequency (VHF) range is the signal spectrum from 30 to 300 megahertz (MHz). To receive a specific VHF signal, you simply need a dipole antenna. Comprised of two lengths of wire or other conductive metal, a dipole antenna's shape allows the incoming signal's ...
Multiple half waves dipole antenna: Although the half wave dipole antenna is the most popular, it is possible to use a dipole antenna or aerial that is an odd multiple of half wavelengths long. The radiation pattern is very different, but it still operates effectively in this mode. Folded dipole antenna: As the name implies this form of the dipole aerial or dipole antenna is folded back on itself.
A simple metal detector circuit diagram project is designed using IC 555, as you can see in the 555 timer circuits, these circuits detect the metals and magnets. When a magnet is near to the 10mH choke, the o/p frequency changes. This circuit can be powered from a power supply, which can provide an o/p DC voltage between 6V to 12V.
more circuit breakers than the number for which the load center was designed, rated, and approved. GE load centers are designed to limit installation to no more than 42 total circuits per load center and thus the number of allowable THQP circuit breaker spaces may be limited. For information on which load centers accept THQP circuit breakers ...
A good, long antenna is an electronic component vital to the successful operation of a crystal radio. In general, the longer the antenna, the better. If possible, try make your antenna at least 50′. Longer is better. You can make your antenna from just about any type of .

Antennas for the Beginner Every ham knows how to make and install wire antennas. But if you've never done it, you probably have a few questions. Here are some answers. realizable goal for a Novice station using one antenna on four bands is to work all states and Canadian provinces, along with some casual DX (Europe and South
Materials; Materials Make the Difference in Low-PIM PCB Antennas. Certain characteristics of circuit materials can indicate whether a material will contribute to higher or lower levels of PIM for a printed-circuit RF/microwave antenna.
May 22, 2020· While a well-designed flexible circuit will eliminate many connectors, ultimately most flexible circuits need to connect to something. Probably the most common entity that a flex circuit connects to is a rigid printed circuit board, but cable harnesses, polyester...

Apr 12, 2017· A great thing about ham radio is that you can spend literally as much or as little as you can afford and still enjoy the hobby. In fact, you will likely enjoy it more by building your own simple equipment, and then making contacts with it. An inexpensive way to begin is to build your own antenna tuner. An L-network ...

Gold is actually a worse conductor of electricity than copper, though in practice that matters little. The only real, physical reason to use gold is that unlike copper, it doesn't tarnish.
How to Extract Gold From Electronics: In this Instructable, I will show you how to extract gold from computers using products most people have lying around in their homes. The way I extract the gold is relatively straight-forward and pretty easy, but the chemicals used are very danger...
• A whip antenna in itself is not an antenna. The antenna is the whip plus ground. An antenna has two poles, qualifying it as a circuit. These explanations are not compatible, and they are speaking different languages, or at least different dialects. It is not clear whether the antenna is the load or a conductor connected to the load.
There are 2777 circuit schematics available. The Last circuit was added on Thursday, November 28, 2019.Please note some adblockers will suppress the schematics as well as the advertisement so please disable if the schematic list is empty.
...But for WA conditions the metal detectors that will find you the most gold nuggets are the Pulse Induction metal detectors like the Minelab 4500. Attached is a link to the compare metal detectors page, perhaps that will assist you with the decision YOU need to make to purchase the detector YOU need for your metal detecting profile.

a circular head where we will fit a coil of wire into for the inductor of the tank circuit ; We will also add a potentiometer (silver) to make the sensitivity of the tone changes adjustable. The inductor coil is made from approximately 50 wraps of 26 AWG wire around a spool of 5.5 inches in diameter.
