This page contains material related to the technical issues on taking meteor counts thus monitoring the meteor influx using VHF radio receivers. It is not meant to be a comprehensive how-to guide, but tries to fill some gaps and give second opinions on observing techniques partially based on some real data presented here. There are plenty of sites

on the Internet describing individual observing setups and some simple guides on why and how meteor trails are observed with radio. You must have seen them. I did not see it necessary to make another copy of such page - or any other kind, until I noticed there just might be some reasons for creating this document. One of them was the confusion on the purpose of MS-Soft - which is not the meteor counting software. The other reason was perhaps the lack of documents containing information on more, than just one kind of setup and software. I was missing a document giving the key features of different types of operational observing systems. Perhaps the comparison table I have made, will make the picture clearer and more objective to all. See what is on the table and think for your self! I do not list all methods I`ve been proposed, or heard used, to do the job - though some of them were quite hilarious, as are some amazing explanations on some documents. So excuse me - I am not focusing here on a five minute science projects, but on something more. At the latter part of this page there are descriptions of receiving hardware and free software making it a complete description of a home made receiving setup. Some technical skills are needed to duplicate these systems, so if you feel you do not have them, find some local friends to help you out. This document does not go through all the basics of the phenomena, they are found in...
This project fits more for custom made battery casing that can have more space to hide things inside. This switch with few alterations can be used for any other project as well but is designed based on e-bike needs! This project use a clever functionality of....
The circuit described here uses ultrasonic oscillations and operates based on the propagation velocity of these oscillations in the air. Thus, we can easily determine the distance of two points if the time within which the wave travels this distance is....
Sometimes the precious metals are hidden too deep and are not detected except with complicated devices. In many cases, however, small pieces of precious metal buried near the surface can be detected by relatively simple means. Everyone is very attractive to....
Many times for various reasons we forget or can not water the plants that we have in our homes. And many humidity sensors units just notify us with a beeping sound or with a flashing light, that the pot needs watering. But what if we are away from home? This....
The principle behind a metal detector is really very simple. Proof of this is the circuit that follows, in which it proves that the construction of a metal detector can be done in the minute, with few components that we find very easily everywhere. With the....
The sub-harmonic bass generator is a sound producing unit for guitars. The sound it produces looks very much like that of the bass guitar. The octave generator is sometimes quite unusual since it does not produce any of the usual ways of coloring the sound,....
In the past the sounding (sea bottom measurement) was done with the "bullet", that is, with a heavy lead object that the seamen plucked into the sea hung from a calibrated rope. As soon as the "bullet" reached the bottom, the depth appeared directly from the....
This Amplifier was designed to have the following specifications: Distortion less than 0.1% at full power of 100W even at 20KHz. Power has to be attributed to an extended bandwidth. The output transistors must be protected against short circuits. The power....
A series of LEDs serve to alert the gardener when plants need water. Using two conventional digital integrated LEDs and a series of LEDs, we make a very useful device for gardening. The device detects the amount of water in the pot and alerts the grower.....
