With all the different ways capacitors are labeled, figuring out the values of your capacitors can be challenging. Especially if you don’t have a digital multi-meter to test them. In this tutorial, I’ll show you how to build three different capacitance meters using an Arduino and a couple resistors. After finishing this project, you’ll be able to measure all […]
Part sourcing is one of the most important and challenging activities associated with the development of any hardware project. So, selecting the right one is a critical step in the success of any product. From finding the exact components at the desired quantity, to buying the components at a price that suits sales margins, getting

The operational amplifier – or “op amp” for short – is a common building block in analog electronics. Whether you’re a professional electronics designer or just getting started, it is likely you’ve used an op amp in your designs. Invented in 1941 by Karl D. Swartzel Jr. of Bell Labs, the op amp was originally

New modulation method increases operational lifetime of switching power units through digital, highly dynamic control and the use of film capacitors. Switching power units are used for the power supply of many electrical devices, e.g. computers, LED lights or laser welding equipment. They convert alternating current from the mains into the direct current required by

One of the most interesting thing about being a maker is you never get tool-stranded, with the right components, makers tend to have the ability to build makeshift tools on the go. Today, we will take a look on how to build a cheap version of one of the most important tools for any electronics

A New Kind of InstrumentI invented Kravox during a research project at Lund University (Sweden) with the aim to give digital musical instrument controllers the feeling of conventional, mechanical instruments. Now I want to make Kravox accessible as a musical experimentation platform for everyone, so I created this detailed Instructable to enable as many people

Measuring just 0.9×0.6×0.3mm (50 % smaller than a conventional 32.768 kHz crystal resonator), the WMRAG series 32.768 kHz MEMS resonator is the world’s smallest, claims manufacturer Murata. Murata Manufacturing Co., Ltd. (Head Office: Nagaokakyo-shi, Kyoto; Chairman of the Board and President: Tsuneo Murata) has developed the world’s smallest 32.768kHz MEMS resonator, which is expected to
32.768 kHz MEMS resonator is only 0.9×0.6×0.3mm Continue Reading
The Arduino is the ultimate tool in the Maker’s arsenal. You should be able to build your own! In the early days of the project, circa 2005, the design was all through-hole parts and communication was via a RS232 serial cable. The files are still available, so you can make your own, and I have, but not many computers
Relive the fun of early computer game music with an authentic 8-bit chiptune synthesizer, which you can control over MIDI from the comfort of any modern DAW software. This simple circuit uses an Arduino to drive an AY-3-8910 programmable sound generator chip (or one of its many clones) to recreate that 1980’s sound. Unlike the many designs
Going all the way hack to the heady days of Eee PC modding, hardware hackers have been on the hunt for small USB hubs that can easily be liberated from their enclosures and integrated into whatever project they happen to be working on. From time to time you see recommendations out there for makes and
