T3: This coil is wound on a small binocular core. One turn is a pass through both holes. The
secondary is a single turn, one hairpin passed through both holes. Insert this wire first. You
might want to mark the secondary end with a dot of nail polish. Then wind the primary, 5 turns,
starting from the other side of the core from which the secondary exits. Try to keep the wire
snug to the inside of the core, or it might be hard to get all the turns in.
Smoke test:
There is no test for this group, move on to the next group.
