“Waveform generators (also called function generators) are useful for testing and debugging circuits. I often use them to test the frequency response of electronics components like op amp and sensors. This waveform generator is powered by an Arduino. It outputs …
“Traditional security camera solutions are very good at detecting movement however these solutions are unaware about what that movement actually is. They cannot automatically tell the difference between trees moving in the air, or a car or a human. We …
“Believe it or not, computers existed before microcontrollers and CPUs were around. They used to be built using discrete parts including simple ICs and transistors. CPUs are arguably the center of modern electronics, whether it be a mobile device or …
“A discussion over the Squidwrench Operating Table about injecting entropy into VMs before / during their boot sequence reminded me that I wanted to try the Entropy library with my 8×8 RGB LED matrix. The original version trundled along with …
“This is a Ardunio based robot that tells you with audible voice if your plant needs a water. You just turn it on, stick him in a dry pot and you should do as the robot tells you. First it …
“A recent project at work required that I drain water from two tanks periodically. Since both of the tank drains are located below the level of all the drains in the room, I would fill up buckets and transfer the …
“For our final technical project we decided to build an electric go kart using commonly available components. The requirements were to implement project management principles, hardware, and software design. The project build time was about 3 months, but the research …
“aka LED Ladder Display Game System. An Attiny-85 outfitted with hardware and software to play action packed “video” games, on a in-line LED display. It has a multiplexed 12 LED ladder display, and supports up to 6 button inputs and …
“A lightweight, self contained, solar-powered weather station for the Raspberry Pi.”
“The automotive electrical system is a harsh environment. Normal voltages range from 9 to 15 volts, and even greater extremes. A jump start from a tow truck often pushes 24 volts down the wires. Stopping the engine can generates a …
