For the past several weeks we’ve looked at blinky LEDs, 555 timers, and resistors. This week it’s time to put it all together into an application. A YouTube subscriber suggested the project as follows: How would you go about having an led blink twice, then a different one blink twice, then back to the original […]
The 555 timer has many uses and in this video we’ll explore two different ways to utilize the output. First we’ll see how the the timer can be used to source and sink current and secondly we’ll look at a way to use the timer as a control mechanism for another circuit. If you missed […]
I am slowly in the process of developing another class, but this time I want to go about it a different way. I’m going to be letting everyone else in on the process. The coming class will include a lot of projects, so during the development of different modules, I want to present some of […]
When I was developing the VoIP Fundamentals course, I wanted a demonstration to illustrate the simplicity of the public switched telephone network. After combing through the internet, I came across this ingenious little project. With just a 9V battery, a resistor, a telephone cord, and a couple of phones you can create a simple little intercom […]
Lately I’ve found myself surrounded by amateur brewers. Many of my colleagues and friends have really bought into making their own beer or cider and I’ve been curious about the process. Below is a video of what happens when you have no idea what you are doing.
