After completing the previous project which could locally or remotely control DC power through the use of PWM. I started to think about methods to control AC or mains power. This of course presents a new set of challenges. First of all, our single transistor used to switch DC previously cannot be used. Second, we

After having acquired quite a few LED strips from irreparable televisions, and having fun building circuits to drive them, it became clear that some way to control them in a more meaningful way would be useful. A simple on/off switch could suffice, but dimming would also be a nice feature, and perhaps means of remote

The Peernix IR Remote was created to be an easily programmable hardware platform to duplicate a infrared remote control, or simply create your own remote control. It uses the Atmega328P microcontroller, so it can easily be programmed using the Arduino IDE. Another couple advantages it has are that the buttons are individually tied to separate

After completing the JBC soldering iron project, and buying a few expensive tips for the iron handle, I decided, after a friend mentioned the lower cost of the Hakko style soldering iron tips otherwise known as cartridges, that maybe it’d be a good idea to buy another soldering iron handle, and try out the T12

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

A few years ago, I was spending a considerable amount of time away from my apartment. Some of this time arose during the winter months, and I found myself wanting to reduce the heating costs of the apartment, and therefor the temperature while I was away. Because the unit is adjacent to a few others,

One of the first Arduino projects that I started off playing around with was a clock. The project went through various iterations, and served as a learning experience for me. The first few sets of code I ran did not use a RTC (real time clock). At first I didn’t notice, or was not too
