Need help for a MEG
« on: January 20, 2014, 02:29:58 AM »
I need help to design a circuit for the MEG


 /--|--|--\ 2 input coils used by circuit 1
 |          |
|||       ||| Output coils on each side are used in circuit 2
 |          |
 \--|--|--/ 2 output coils used by circuit 1


The way I want to build my MEG, 2 different circuit, one for the output and one for the input.


The input will start from a piezo lighter that can generate around 300v to start the circuit, once started the
2 output coils from the circuit 1 is used only to power the device (not related to circuit 2).


The other output circuit is only used for the output without any relation with the input circuit.


The help I need is to understand how to switch the input voltage from + to - / - to + 60hz
Also the input voltage can be high, the circuit need to support high voltage to work.


I ordered everything to start up my MEG, so I want to work on the circuit while waiting for my stuff :)


I will do my MEG core with magnetite, I will build a mold using a 3d printer ([size=78%]http://www.qu-bd.com/[/size]) I got one
from this site, around 200$$, I will have the printer in few month, they are back order :( ...


I will test how many voltage I need to switch the magnetic field with a Gauss meter, but I want a circuit to support at least 400 volts, i will wind the output core to generate more voltage with less current.

I will also test with powerfull neo magnet N50 50x20x10mm and with ceramic magnet 48x22x10mm

Anyway any help would be appreciated

I ended up doing this circuit, not sure if it will work, I ordered the thing I need to test this, I need to wait few weeks until I receive the stuffs.


The BEMF stuff not sure if it will work, I put that but its probably wrong... Any update I need to do or issue you see?

Jean Louis Naudin did a lot of experiments with a MEG:

It is difficult to do better and Naudin gave the MEG up.

thank you, i already saw the JN replication, I dont want to use the same chip (TL494CN), I want to use commun compoment for an easy replication if that work.


Also the way i want to do mine is quite different, it will have now 6 outputs coil, 2 for 5v input, 2 for 100v-1000v input and the 2 others to be used on a external load.


So the circuit will be divided in 3 sections, the one I posted is the first, I know its not perfect, but I will correct the problem over time.


He also use a very high frequency 20kHz, I want to test with smaller data first 60hz and increase to see the difference also since I will use magnetite core, it will probably react different then metglass


Another thing, I will do a smaller core in diameter, but as big as the MEG, I am pretty sure the more the core is ticker the less energy you get out from the device.
