With the severe drought going on in California with no end in sight, [TVMiller] decided he could put an Arduino and a toilet together to try and save at least a few gallons of water per day. The invention fills a toilet to the minimum level, saving around two gallons per day for the average “user”.
A typical toilet functions by using gravity and moving water to create a vacuum, sucking the waste down and out of the toilet. As long as there is nothing, uh, solid in the bowl, the toilet will be able to function on the reduced amount of water. The Arduino cuts the flow of water off before the toilet fills up the entire way.
In the event that anyone -ahem- needs the toilet’s full capacity, there is a button connected to the Arduino that fills the reservoir to capacity. [TVMiller] notes that if 1,825 hackers installed this device on their toilets, we could save a million gallons of water per year and be well on our way to saving the planet.
The project site is full of more information and puns for your viewing pleasure. We might suggest that the “2” button would be very easy to integrate with the toilet terror level indicator as well.

How was your week? We got to spend a couple of days trekking around the Carnegie Mellon campus in Pittsburgh, PA to check out some of the latest projects from the school's world renowned Robotics Institute -- a trip that culminated with the bi-annual induction ceremony from the CMU-sponsored Robot Hall of Fame. Given all the craziness of the past seven days, you might have missed some of the awesomeness, but fear not, we've got it all for you here in one handy place -- plus a couple of videos from the trip that we haven't shown you yet. Join us after the break to catch up.

Emily Gertz and Patrick Di Justo, authors of Environmental Monitoring With Arduino (available from Maker Shed and O’Reilly), wrote it to let me know that the book got used as a textbook in the recent NYC Water Hackathon. They’ve got the pictures to prove it, too!
Brooklyn, NY, March 25 — Patrick and I went to the Gowanus Canal to observe the testing of prototype water monitoring devices created at the weekend Water Hackathon. The Gowanus is one of Brooklyn’s more notorious Superfund sites.
We were excited to see that the device being developed by Leif Percifield and the citizen sensor group Don’t Flush Me is based on the water conductivity gadget we devised for Environmental Monitoring With Arduino.
We designed our gadget to test water samples in a controlled setting, such as sitting at your desk with the samples in flasks. They’ve adapted our water probe with little spade terminals, to be more durable in the field. Brilliant!
