Soldering is the backbone of electronics, connections are made using molten metal. Obtaining a soldering station for electronics use can be done rather cheaply. Even cheap soldering stations can be enough for most applications. However, once you come upon larger ground plains,(larger areas of metal) or larger devices, such as bnc connectors, it can take

This article is on the final revision of the Arduino Fan control board “CoolRunnings”. I’ve written about the first two revisions, from the board that I etched myself, to the first one from a board house, which still contained a boost converter. After that one, I designed one to be powered with a barrel jack,

Inspiration for a car alarm, what could that be? Around the beginning of 2018, I came into the prospect of buying a 2006 Jeep Liberty. I had been happily driving my 1998 Toyota Camry for years prior, and hadn’t really thought about acquiring another vehicle, but something about 4WD, and driving a big powerful vehicle

After I finished my last Real Time Clock project, I was relatively happy with the outcome, well, everything except for the accuracy; and what good is a clock without accuracy? I used the DS1302 which I’m sure is a pretty decent RTC(real time clock), if you pair it with a crystal that’s perfectly matched for

The ESP8266 relay project started off as an attempt to control a relay with the ESP8266 from a wireless interface, such as a web browser. The idea can easily be achieved with a few different modules which are available from eBay relatively inexpensively. I however usually don’t like the idea of assembling several modules to

After my first fan controller was competed and working, I was pretty happy with it. But as I learned more, experimented more, and became familiar with more hardware, I realized much more could be done with the controller. With the previous controller, I used the Attiny85, which was perfect for the job it was given,
