I bought a Freeduino board months back wanting to create an automated overhead tank filling system. However, I could not find a cheap and easy switch in my city, hence eventually the project went into the back of my shelf, until today morning. Woke up early and went to wash my face, realized the tank was empty. Now I didn’t want to start the pump at 4am and wake others up — I remembered the project is waiting to be assembled.Went through the components I had lying around and came up with an idea… I could put this together in some time, so I started… Used small hacksaw to reduce noise, cut myself two long planks and two one inch by one inch square bits. Had a push button switch, drilled two holes in one plank and fixed the switch with some hot glue…
Next, cut the actuating lever into shape…
Drilled holes for hinge
First hot-glued the bits, then secured them with two small nails each. Used a copper wire as guide to align everything properly while working on it.
And… it was ready.
Now all I had to do was solder wires and put the contraption upside down handing over the overhead tank…
The nylon string ensures that the float rises up in the correct direction Put a multimeter to line testing mode, wired up and checked by starting the pump… it worked! Next up, the freeduino/arduino bit
