Running multiple computers can have advantages. In my case at my desk I run a windows machine during the day, and keep a Linux machine running around the clock for various tasks. Usually remote terminal access is all that is needed for day to day interfacing, but sometimes I’d like to be able to access

Over the last few decades, power supplies have changed quite a bit. In most small inexpensive consumer electronics of the past, you’d find a small transformer, and a linear voltage regulator. This worked quite well to achieve low voltage DC for the product to operate. There are however limitations with this kind of supply for

With the advent of larger and larger phones and mobile devices that contained increasingly larger batteries to accommodate their thirst for energy, new types of power sources were created that centered around the 5v USB standard, but also allowed for increased voltage and current, in order to accelerate the time required for them to charge.

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

More soldering stations, are you nuts? Ok maybe, but probably no. One thing you learn about electronics projects after you finish them, is that you wished you would have known things you didn’t know starting out, and you’ve probably also left things out that you shouldn’t have. This is what gave way to the STM32

While the Atmega328 has enough processing power for many applications, sometimes you need a bit more. While trying to drive OLED displays, and run various other time sensitive tasks, you can come into performance issues. A faster chip, that is also supported quite well by the open source community is the STM32 family. There is

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
