Just making up an arch and the Pixel strip need to be trimmed down to just under 4M, decided to make them 125 pixels long, 375 channels per arch


Here's how i soldered some wires and sealed the cut end.

Just push the tube back a little and hold in place

At this point i soldered on wires only to Gnd-SD-CK.... the wire is only there to grab onto rather than for use.
Next pulled tube back down over joint and injected silicon inside tube

Next slip some clear heatshrink over the joint and add some more silicon

Next heat-shrink shrunk using hot air gun. expect a little silicon to squeeze out, i always see this as a good thing and then just clean up with a tissue to remove the excess.

Thats pretty much the way i do it as well and has worked perfect for 3 years

Just ensure you use non corrosive, neatural cure silicone

I do it the same way, except I use end caps (I bought 500 of them for next to nothing), but the same basic idea minus the heatshrink.

Neutral cure silastic is a must - I had to repair a strip I gave a mate for his work ute when he used normal acetic cure to seal the ends... lasted a few months before failing and on closer inspection the copper had literally been eaten away by the silastic he used

Selleys All Clear .... I wouldn't use it for this.


I use PARFIX roof, gutter and concrete highly flexible clear silicon, Neutral Cure, Non-Corrosive.


Any brand will do as long as the label say all of the following... Clear - Neutral Cure - non corrosive AND Silicon
