| - | [* black] When you can see two separate bits of bright copper side by side you are ready to go. Next, you need to make a cut of about 3-4mm using a sharp blade. I used a craft knife. This is not as difficult as it may appear as you can "feel" the space between the tracks if you apply a very light pressure. |

| + | [* black] When you can see two separate bits of bright copper side by side you are ready to go. Next, you need to make a cut of about 3-4mm using a sharp blade. I used a craft knife. This is not as difficult as it may appear as you can "feel" the space between the tracks if you apply a very light pressure. Hold the ribbon flat with a blob of Blu Tack and position the ends of two 3-4in lengths of 46 AWG wire as shown. I used bare copper but solderable varnished wire would be better. Hold the wires with another blob of Blu Tack and carefully nudge them into position. |
| + | [* black] When the two wire ends are in position, apply the silver paint over them. Try to leave the paint just below the cut in the ribbon. If you carefully part the two pieces with a thin sliver of plastic you should get a reading with testmeter set to "Diode". Infinity one way and about 1.5 ohms the other. You're reading a silicon diode somewhere. |
