Homemade Neptune Apex Breakout Box

Thought I would share my just finished and tested (and works wonderfully) Neptune Apex Breakout Box. 😉 The Cable that plugs into the Apex is the same connector that Apple serial printers of yesterday used so they are cheap and easy to find. I decided on RCA plugs for the interface because I think they are clean looking and they serve the purpose nicely.
This is the inside connectors all soldered up

 

 

 

 

 

Here is a picture of it finished. The lead I have plugged into one of the ports is from an old sump alarm which when the contacts were closed with water it would sound an alarm. The alarm stopped working so I cut the lead off and soldered it to an RCA adapter and now I have email alerts for if there is a leak with my tank using my Apex
