I have been working on a wireless sprinkler project where multiple sprinkler valves and controllers will be scattered around the yard where every I can access a sprinkler main or a hose bib. The goal is to control them using a raspberry Pi and low power Arduino chips running on battery power. I also will be using the data from my weather station which was designed for this purpose. The weather station is at https://www.thingiverse.com/thing:2854433.
My first stumbling block was finding a socket for the connector that would work with the Orbit 91592 type valves that I have.
This block is the first step on the sprinkler valve journey. My plan is to incorporate this socket on the bottom or back of a waterproof case that I have not yet designed.
As I continue the journey I will update the instructions
This thing was made with Tinkercad. Edit it online
I have uploaded a new version of the connector I call it v2.5. The epoxy wells were too small and I ended up with expoxy in places I did not want it. So I enlarged the wells.
Using the Socket
I am using 1/16" (1.57mm) brass tubes (K&S #8125) as the pins for the connector. The Orbit valves have connectors that are about 12 mm deep and the base of the printed socket is 6mm.
I found that I had to clean out both small and large holes in the base. I used drill bits that would fit into a hand drill.
If you are using a saw I created a cutting block that helps. I printed it at 40% infill with a 2mm shell. if you are making many of the pins you may want to print it solid.
After you cut the pins there will be burrs where the cuts were made. I found that a Pin Vise could be used to securely hold the pins and then a Utility/Razor knife could be used to remove the burrs.
Insert 22Ga solid or stranded wire into the tubes and solder them into the tubes.
( Be careful to not get solder on the outside of the tube)
Insert the prepare Wired-Tubes into the block being careful to not break the wires. A little of tube should extend out the back
put a bit of epoxy in each of the larger hole out the back of the block
- To use this socket block Drill holes in to a water proof box, thread the wires through the holes and then epoxy the block to the box.
I used PLA on my version to use this outside I would recomend painting with Plastic UV protected paint.
The orbit valve seem to use 24 volts to latch it open and -24 volts to close it.
