Ok, that's just flat out cool.I have made a tool that will make things much easier for me in my DIY tub and bucket sips. I have tried dowel rods with fishing bobbers to make a floating water level indicator, but nothing small enough to get down in the fill tube will make it float. So far I've only had a wooden dipstick to let me know where the water level in the rez is.
So I called on my ham radio and electronics engineering experience and created an electronic dipstick. At the top I have eight LEDs that indicate the level of the water and at the bottom I have sensors spaced at the points I wish to know about.
Here is the ground:
The wire at the very bottom is my ground and then another sensor is spaced one half inch above that. I start at 1/2 inch and move up to 3 in and then I go every inch above that.
It's not yet prettied up but the basic design prototype has been built and appears to be working well. In the future I will add a display panel that directly indicates the water level in inches and a switch to turn it off and on.
The top circuit board includes one LED for each channel with a 380 ohm drop resistor that makes it a good match for a 9-volt battery. I got fancy and added mounting blocks for the wires coming in.
The wires were run through the tube through holes drilled at the bottom at the appropriate places. The wire was stripped at the end and bundled into a ball that was soldered and then melted into the PVC at the appropriate place.
Bravo, Miss Em. Bravo.
