Smart Irrigation System

During the summer, gardens abound — so many people are keeping an eye out for their sun-ripened, home-grown tomatoes or for that lovely hydrangea that’s just the right shade of blue. But summers are also a very hectic time. So how do you maintain that garden and make sure it receives the care it needs? One of the projects created for the Digilent Design Contest 2015 is a smart irrigation system intended to work with an Android device to see to it your garden gets the moisture it craves.

Soda Can Theremin Video

We recently published a video about a simple Theremin built using the Analog Discovery and the Analog Parts Kit. A Theremin is an electronic musical instrument which essentially turns the user into a variable capacitor. The user can then adjust the frequency of the sound produced by the instrument by moving their hand in relation to an antenna. As the distance to the antenna changes, the capacitance also changes, thus changing the signal frequency. In the Theremin showcased in this video, a recycled soda can is used as the antenna.

Instruction Pipelines

Implementation of an instruction pipeline is a common technique used when working with microprocessors. Pipelining improves operation and processing time. Microprocessors such as the Microchip® PIC32MX460F512L on the chipKIT Pro MX4 board use this technology to provide efficient processing and instruction execution. Though the process is sophisticated, it is actually quite simple in concept. In my explanation of instruction pipelines, I’ll specifically refer to the Microchip PIC32 microprocessor.
