DIY Dirty Dish Detector
Nothing stinks up the house like a kitchen sink filled with filthy dish. Well, a full trash can will do it to a greater extent, however that’s a task for a later date. In what must be an overreaction to a constantly full sink of dishes at his London Hackerspace, [Tom] developed a web-connected dirty dish detector.
He named it the Great OpenCV Wash-Up Detector. The device comes with a line of various signals to inform those geeks about cleaning up after themselves. The first execution utilizes a traffic signal to inform the area that there are filthy dished to be washed; illuminating several colours to point out the length of time the kitchen sink has been full. [Tom] additionally plans to incorporate message bursts to the IRC room, as well as air horns once the condition becomes terrible.
As the name indicates, this utilizes OpenCV in order to recognize circles in the sink. A webcam has been installed on top of it directing all the way down, rendering a definite input image that will determine dishes, cups, and so on. [Tom] also wrote several code which disables the device once the lights are switched off.
Naturally, this may teach offenders to abandon the dishes within the counter where the detector can’t discover them.

He thought to take an in-depth look at the DHT11 sensor; which you can get hold of for less than $3 once you discover the best places to search.
A high school junior from Massachusetts named Daniel Kramnik submitted an entry for Water Quality Science Olympiad event. His project is an award winning Digital Salinometer.
[L] just completed creating this unique intervalometer and his wordy documentation of the task incorporates a little bit of everything. The fabrication utilizes typical prototyping components, as well as basic knowledge which are simple to learn even for the inexperienced.
[Steven Dufresne] spend a lot of tinkering with solar-powered applications, an activity which can be extremely time consuming if performed correctly.
