In this instructable I'm going to show you how to build a mosquito repeller using an Arduino. The repeller is in the form of a shield that plugs into the Arduino board and the frequency of the repeller can be changed easily. This project is ideal if you are going camping or hiking outdoors, this device produces a sound of 31KHz Frequency which acts as a mosquito repellent. The frequency of this device ...

I'm a huge fan of technology and music, but when I decided to start making my own electronic music, I was discouraged by the high price of MIDI keyboards and controllers. After a lot of tinkering, I saw the opportunity to create my own MIDI keyboard using an Arduino Uno and electric paint, for a fraction of the price compared to existing MIDI devices! In this tutorial, I will explain and show you how to cre ...

Typically, amateur radio operators use the minimum power needed to accomplish a contact. That’s just part of being a good spectrum citizen, and well-earned bragging rights go to those who make transcontinental contacts on the power coming from a coin cell. But sometimes quantity has a quality all its own, and getting more power into the ether is what the contact requires. That’s where builds such as this we ...

This is a sponsored post discussing about PCB assembly costs factors on Bittele Electronics.

After my initial PCB success with Maker Studio, I uploaded the design files to three more board houses. I had planned to try four or five more, but I started to get the impression that many of the China-based sources used the same fab house, so I stopped at three. Elecrow's basic board fab service supplies 5 or 10 PCBs for $11.90, with a basic international shipping cost of around $7 for 5 boards. Although ...

Fidget spinner became a popular toy earlier in 2017. Most of us have one or at least have tried it. Consists of a bearing surrounded by a three-lobed flat structure, it can spin along its axis with a little effort. Makers and hardware hackers always try to employ different tools to make innovative ideas. Some of those makers hacked a fidget spinner to display custom text while it is rotating. The concept is ...
