Diy rodi refill system.

[willtheld]

So I've been eyeing the avast barrel tender and finally thought, I could make that myself.


So after some searching I found a 12v pcb that would trigger a relay when one circuit opened and turn it off when another circuit closed.

Easy enough, wire up a couple of float switches add a solenoid and done.

Now my rodi will magically turn on when my 20 gallon trash can is near empty and shut off when full.

Extras I included were a float valve incase the solenoid fails open, and a third float all the way at the bottom below the "low" float to set off an alarm on apex to check the system if it's not filling


Here are a few pictures, id include one of the pcb but it's boxed up in a project box sealed up.

Here's the solenoid

The low float to turn on the rodi and the emergency apex float

And the inside of it all

*Bump* Do you have a link to which 12v PCB you used? Would like to build one myself.
