I need help to design a circuit for the MEG
/--|--|--\ 2 input coils used by circuit 1

\--|--|--/ 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/ (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
Hi TheOne,
may this will be interesting for you, see page 54-

Thank you, i will take a look to start with something :)
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.
