"Monitoring and controlling relative humidity is important for humans health. Too low or too high humidity feels uncomfortable, but most importantly high moisture is a factor for growing mold in your home, which could be health threatening. I will not go into details on how to control humidity. Instead I’ll describe what motivated me to design and create my own temperature and humidity sensor which reports its readings every minute to a central Linux server."

"This circuit is simply a digital thermometer. I use a Microchip PIC Microcontroller to communicate to a Dallas DS18B20 Digital Temperature Sensor, interpret the data, and display the temperature on a multi 7 segment LED display."

"I was motivated to find a new solution to controlling my garage door because I didn’t want to carry an extra remote around, and they just don’t work very well. This article demontrates how to use a CC3200 to connect to an existing garage door opener. The CC3200 acts as a TCP server which can send information about the garage door state to any network capable device."

"Having good support for your arm/hand when operating these large sticks makes it a lot more comfortable, ergonomic and gives an accurate control. The major drawback is that it isn’t possible to carry or hold it without some sort of harnesses or extra support."

"The third version of the Led logger has run without any major issues. Based on uptime logging there has never been any freeze or malfunction. As for the LEDs, I have identified a few types of strips based on the behaviour they manifested throughout the experiment. Careful about the axis scale of the graphs."

"In today’s blog post we’ll analyze one of the smallest and most practical boards out there. The Digispark board. It’s size, including the USB port, is 25mm x 18mm (so tiny)!! This little board is powered by an ATTINY85 chip and clocked to 16.5Mhz. For conveniece, it has a built in USB port and can be plugged into a your computer without cables or adapters."

"This one is an interesting one, it’s something we’ve been looking at for a while and figuring out how to solve it. We have sets of speakers and projectors and the users keep losing the remotes, or misplaced/stolen. Usually this wouldn’t be a problem, we’ll just contact the supplier or manufacturer and order replacements. Except we can’t any more."

"Combine an Arduino Uno, an Adafruit Servo Shield, Xbox 360 Controller, and a beat-up 1981 Kenner At-At Walker and the result is the toy I always wanted when I was a kid. If you played with this toy growing up you will probably remember how clumsy it was and difficult to move around."
