Back from Bunnings with the irrigation fittings I need so we can now start building the low voltage motion activated sprinkler.
From left PIR Sensor, Impact Sprinkler, 15mm Female To Female Rural Poly Irrigation Coupling , Irrigation Solenoid, 15mm Female To Female Rural Poly Irrigation Coupling, 13mm Tail x 15mm BSP Male Director, then garden hose (phew).
Fiddling with layout on length of pine timber.
Measuring up a bit of plywood to hold the sensor and suction mount. That nut is from the sensor threaded base mount.
Marked out the hole for the sensor threaded base.
To drill (or bore) a large hole like that in a small piece of timber we need to use a Forstner drill bit.
