Bar Sign Part 3 - the el wire
- The arrows will look like they are moving by using a by
for sequencer. Because we are using a 4 step sequencer,
every forth arrow will be connected.
- To save on about 24 feet of el wire, we wired each arrow separately
rather than stitching them together with one piece of el wire.
- Each segment was terminated with a pair of wires (under heat shrink) on one end and heat shrink on the other end. This sign will be exposed to the weather, so we also covered the ends with silicon before applying the heat shrink.
- note: we used clear silicone because we found white silicon (or caulk) was slightly conductive so the wire would not light up if we used it.
- The el wire arrows were attached to the platform with 3 tie straps each. Black ones on the end and a clear (white) one at the tip of the arrow.
- every forth arrow was wired together
- The wire between each arrow was covered in black heat shrink so it would be less visible against the black background.

- The letters were covered with blue el wire. Between letters and areas where we did not want the el wire lit up, the el wire was covered with black heat shrink.
- We now connect the invertors
- As this sign will be outside in the elements, we placed the inverters and connections inside an inverted peanut butter jar.
- note: the water will run down the side of the jar and collected in the lid, so the items inside the jar should be lifted off the bottom (lid) and the lid should be drilled with holes to drain the water.
