This is my attempt at constructing this moving charge sensor the attachment here when you click on the link will take you to the site but the circuits not very detailed so i managed to work it out myself and if i throw in your buzzer circuit ill have a circuit that will buzz when the static charge approaches and the left led will come back on when the charge recedes or move away , Ive already built it on a breadboard and it works and i just have to make the printed circuit board version and add your buzzer circuit like i did with your ghost detector circuit now ill do some digging see if ghosts and static charges are a common thing if so then this may be of some use ill email you pictures when i built it in the printed circuit version.
I strongly feel that talented electronic hobbyists like you needs to be introduced to the world. So please let me know more of your scientific developments, I would be pleased to publish them through my blogs. Also, if possible describe your experiments with images.
Thanks and Regards.
thank you swagatam im just a pensioner who dazes into electronics and if i want to learn something i collect it and store it in my external hard drive as a future data base to preserve the knowledge its a hobby to collecting knowledge you are welcome to use anything i email you for your site , i built a simple trigger coil tester a few years ago and i recently found out it has a use as a relay energize de enerigizer, indicator that will indicate voltage to the relay and the reverse voltage in the coil from the relay coil its a simple circuit but it only works if you use a camera trigger coil so what better way to tell the status of your relay than to use this circuit . ill email you details soon as i get it ready and decent here's what the trigger coil tester looks like it has 9 volts battery input and the diodes are all 1n4148 and the electro is 4.7uf see the thick wire coming out one end of trigger coil disconnect it and solder wire from one input of relay to that pin where you removed the thick wire of trigger coil and you see between capacitor and trigger coil front there is a thin wire you connect another wire to it and run it to the other relay input, and when you activate relay one led blinks on and off and when you deactivate relay the other led blinks on and off only 2 legs of the camera trigger coil are use for this .
here's a rough drawing from my pc of the trigger coil tester important i forgot to mention when you modify it to act as a relay status indicator you do not need the battery input as its power comes from the input voltage to relay and reverse voltage from relay coil so use no battery input at all. points trigger coil not shown point b and c, b is the thinnest trigger coil wire at front next to thick trigger coil wire and c is just a matrix pin where the other end of thick trigger coil wire was connected to you remove that single wire connection and run one of 2 relay input wires to and the second relay input wire the thin wire you run it to that , ill do a better drawing next time and show you better details its late here so ill get back to you.
Can you please provide a more clear diagram of this so that the other readers may also understand the concept easily.
ill get back to you heres what you requested, ill send you full details of moving charge sensor when i start and complete it
I will post these in my blog section very soon.
Here is the completed moving charge sensor circuit, using your buzzer circuit from the ghost detector circuit, the home made optocoupler circuit .
Thanks a Lot, a small request - can you please write a small description regarding this circuit, like: its use, applications and regarding your experience with it. That will help the other readers to know about the circuit better.
A small explanation will do.
hello thank you for your reply im not very good in the explanation of circuit functions but ill try the circuit is a moving charge sensor circuit , it basically was said to indicate static charge approaching and receding by doing this one led lights when the charge approaches and the other when it recedes so by modifying this charge sensor by the addition of the swagatam buzzer circuitry ive modified the second led in the circuit by converting it to the swagatams version of the home made optocoupler . transistor type buzzer so when charge approaches the led on the left blinks and when it recedes the buzzer comes on for that i hope this is ok
when i built the circuit and added swagatams ingenious home made optocoupler with buzzer i tested it by rubbing a plastic static conductive ruler on the back of my head to simulate a static charge , and when i brought it close to the coat hanger wire aerial i plugged into it, the red led blinked and the buzzer sounded and pretty far enough to as the charged ruler had so much charge on it that the it can still detect the charge at a good distance for the size of the ruler so the idea is if ghosts and UFOs besides other things have anything to do with static charge generation then this may be useful in the field some info says ghosts also create some static charges so if true this instrument may be useful so if ghosts use any electrostatic charges this may help in determining what direction or if its coming or going . and if ghosts happen to leave any traces of static charge build up on anything after it has come and gone then again this instrument be handy as it will register objects that retain some of the charge left on it
