The problem is, timecode alone, while sufficient to provide syncing points for post production, may not be a reliable way to keep devices in sync with each other. With timecode, unless the cameras or recorders are re-jam-synced frequently, their timecode will start to drift apart. The problem is that the quartz crystal (or other piezo-electric material) clocks used in many cameras and quite a few audio recorders are too imprecise for critical applications.
Roller Naps. Paint roller nap sizes range from 1/4 to 1/2 inches in length. When painting a ceiling, the selection of a roller nap size depends on the surface of the ceiling. In general, a ceiling with a matte, flat, or eggshell finish calls for a roller nap of between 3/8 and 5/16 inches. If the ceiling is more textured, however, a longer nap may be called for.
5. Note the exact location of each wire connected to the switch. Ceiling fan manufacturers do not use the same color wires to connect the ceiling fan motor to the speed switch. Make sure you write down which color wire connects in each slot on the speed switch.. Turn off the circuit breaker to your ceiling fan circuit. Hold a noncontact voltage sensor next to the wall switch that powers your ceiling fan. If power is still present at the light switch, the noncontact voltage sensor will flash and sound an alarm.
