When it comes to keeping in touch with the grandparents, a lack of familiarity with modern technology can get in the way. [palmerabollo] wanted to share photos with his grandmother, but found that it was difficult as she didn’t have a smartphone or an Internet connection to receive photos. Thus, a custom build for grandma was […]

Control your Arduino with voice commands using an Android smartphone! Before we make a voice activated home automation system, we must first learn the basic principles of the experiment. This guide will let you command the Arduino using your Android smartphone and a HC-05 Bluetooth module. The designer of the app did not include a

I have always wanted to build a fairly capable LCR meter that could cope with real world use in my own personal lab. This would mean reasonably good accuracy across a wide range of L, C and R. Fortunately, I got the time to do just that this year in the 3rd year Instrumentation module
LOW COST HIGH ACCURACY STM32 FFT LCR METER Continue Reading
This example shows the simplest thing you can do with an Arduino Due and an Arduino Motor Shield, driving a DC motor in forward and backward directions. Hardware Required Arduino Due Arduino Motor Shield DC motor Wall wart power supply Circuit To build the circuit you need to mount the Arduino Motor Shield on top

Did you know that researchers are looking for an alternative to silicon? Did you know in principle that Carbon Nanotubes processor could run three times faster while consuming about one-third of the energy of their silicon predecessor? The Engineers at MIT and Analog Devices have created the first fully programmable 16-bit Carbon Nanotube microprocessor. Since Silicon Transistor

When you see something made from metal that seems like it would be impossible to manufacture, chances are good it was made with some variety of electrical discharge machining. EDM is the method of choice for hard-to-machine metals, high aspect ratio hole drilling, and precise surface finishes that let mating parts slip together with almost
