The red an black wires at the bottom go to the batteries. the Red at the top is the Aerial the 3 "phase" connectors are at the bottom

Quick hack. Detects low/high/normal water level and indicates it using 3 LEDs. I didn't calculate any resistor values, pure trial and error. Some of these just work as inverters, so the LEDs light up in the right way.
The red an black wires at the bottom go to the batteries. the Red at the top is the Aerial - completely ignores the swivel "aerial" on the left (!). The red wire is taped to the inside of the case to hold it in place
"Tin" the exposed pins of the 5mm CSLT current sensor with a small amount of solder. This technique makes soldering the wires to the sensor pins easier.
This shows a ibutton style sensor in a circuit board mounting clip. Even though I don't put it in a circuit board, the clip makes it easier to connect the wires to it.
I had difficulty getting the camera to focus in the dark.

Shot of the tachometer sensor setup in the bilges of my steamboat. There's some speculation that the bent brass support may have interfered with readings at some speeds. Tests were going to happen on the second day but a battery wire failure was unfixable without a soldering gun, conveniently left behind! Next week: bench tests with an oscilloscope.
