TEP Bifilar coil construction : The Bifilar coil ( L1,L2) is the main component of this oscillator and must be perfectly constructed.

1) Take a 200 mm length (20 mm diam) cardboard tube and 2 x 11.5 m of 5/10 magnetic wire (AWG 24).

2) Drill a small hole at each side of the tube for the wire, the distance between the holes must be 190 mm.

3) Wind the two L1,L2 coils at the same time, as shown below. You may glue the winding with cyanoacrylate.

4) Insulate properly an 125 mm wide area in the middle of the bifilar.

5) Wind the feedback coil L3 with a 5/10 mm magnetic wire with 250 turns.

7) Put a dot (the hot side) on one side of the bifilar to identify the polarity.

8) Check the bifilar coil with a signal pulse (square) generator.

• a) connect the hot side of L1 with the hot side of L2
• b) connect your oscillocope probe accross the L3 coil
• c) send a square pulse signal on the side of L1 and L2 at the opposite of the hot side.
• d) if your bifilar coil is wound correctly, you should see NO SIGNAL on the scope.
