vinyl that covers the current driving PCB or the
screw holes in the case. Place the next case layer,
which has the open slot in its handle, on top of
the vinyl, then place the final, solid-handled layer
on top of that one. Secure the three case layers
together with five M3×12mm screws and nuts.
The transmitting coil’s power wires will extend
from the end of the case’s handle (Figure
Q
).
When the case is completed, strip the ends of
the red and black power wires if necessary and
screw them into the corresponding +/– terminals
in the screw-terminal-block-to-barrel-jack
adapter. Check carefully to be sure the wiring
polarity is correct. Then insert the barrel-jack-to-
USB cable into the adapter.
Now attach the USB cable to any 5V regulated
power source. Test the transmitter by placing
a few wireless LEDs in the center of the coil to
be sure they light up. Figure
R
shows that the
LEDs facing upwards, with coils parallel to the
transmitter, light up, but the LEDs whose coils
are perpendicular to the transmitter may light up
