Have you ever struggled with audio settings in control panel in middle of a VoIP call? Or, wondered if the other guy can hear you properly? I have. My work requires great deal of remote conference calls using PC. The first thing I wonder always when starting is if my audio settings — mic volume, […]

If you’re like me, every morning before you leave for work you wonder whether you should wear a jacket before heading outside. You might not have time to check outside your front door, but you always have time to check your iPhone! :] The problem is, standard weather apps tell you about the temperature in […]

As someone who is very new to digital electronics this LED cube was fun to make, challenging and a great lesson in soldering. If you have some patience (64 LED’s to solder!) and steady hands, this project will be well worth it in the end! Step 1: Materials & Tools Materials: -64 LED’s ( I […]

ARM has introduced its highest performance Cortex-M series processor core. The Cortex-M7 retains the same instruction set of the other processors in the Cortex M series, but has been given a six-stage super scalar pipeline architecture which dramatically increases its performance over the previous Cortex-M4. Ian Johnson, product manager at ARM told Electronics Weekly, the […]

If you are a pet owner, going on vacation can be stressful. Usually, you need a friend or neighbor to come over every day and feed your pets. However, by enslaving robots you can keep your pet happy and enjoy a stress-free holiday. To save money and learn something new, I decided to make my […]

The purpose of this project was to create a simple, portable device that would periodically read sensors and then store the sensor data so it could be retrieved later. The result is the HexiLogger, “hexi” because it can support up to six different sensor inputs and “logger” because it will store the input data on […]

Stepper motors are great for accurate positioning because they move in discrete steps – a feature that makes them very appropriate for CNC software control. But every once in a while you have an application where you need to press a button and rotate some kind of a jig at a preset angle or move […]

This server room environmental monitoring system is a low cost high performance device with the same onboard features as commercial devices costing hundreds of dollars more. In addition to a low cost platform we will provide low cost sensors for many important devices to insure your equipment stays safe and sound. Full instructions are available […]

Hi all! With a bit of delay, here’s my last work, a PICnano breadboard based on the PIC18F2550microcontroller. I have in mind a new project and I want to use an small board, like the Arduino Nano board. This new project is battery powered (3,7V Li-Ion battery). After checking the schematics of the Arduino Nano, I see […]

After the untimely death of my Mac Mini (the last thing Apple I never buy), I recycled her limping in a clock display LEDs. Technically, there is not rocket science: an Arduino reads the time from an external clock and displays a matrix of 8×6 colored LEDs for hours, minutes, seconds and a linear array […]
