LM2596 DC-DC Converter Module Testing

LM2596 based step-down DC-DC converter modules can be bought on eBay quite cheaply for around a dollar each. But how do they perform? Is it safe to use it to power your design? Let’s find out. According to TI’s website, these LM2596 step-down (buck) regulators are sold for $1.8 each for a quantity of a thousand. So how a finished converter could be sold for just above a dollar each is quite a mystery to me. ...

Simplify DC-DC Converter Characterization

DC-DC converters are widely used components that convert DC power from one voltage to another, producing a regulated output voltage. These devices are used in many electronic products, including laptops, mobile phones, and instrumentation. Like any device, DC-DC converters need to be characterized by manufacturers and by engineers evaluating them for a design. Given the increased pressure to develop product ...

Buck Converter (DC-DC)

Alright! So hello everyone! Long time user, follower, commenter but first time iblest here! So for my first instructable I thought I'd share a recent simple project I made; a Buck Converter. Buck Converters are great! I use them all over the place in many of my nerdy, techy, geeky hobbiest projects. They also can commonly be referred to by other names, a DC-DC converter or a switching regulator. Essentially ...

Playing with analog-to-digital converter on Arduino Due

Today I’m going to present some of more advanced capabilities of ADC built in ATSAM3X8E – the heart of Arduino Due. I like the Arduino platform. It makes using complex microcontrollers much simpler and faster. Lets take for example the analog-to-digital converter. To configure it even on Atmega328 (Arduino Uno/Duemilanove) you must understand and set correct values in 4 registers. And it can be much more in ...

Digital to Analogue Converter (DAC) DAC Theory

A digital to analogue converter takes a series of digital inputs (a string of 1s and 0s, in our case there will be 8 of them like 10011001) and converts it into an analogue output. You see DACs in every digital audio device (MP3 players, CD players) as these all store music in digital form, but need to drive a speaker with an analogue signal. Hence the need to convert the digital data into an analogue signa ...

Low-Frequency Converter

Among the signals below 550 kHz are maritime mobile, distress, radio beacons, aircraft weather, European Longwave-AM broadcast, and point-to-point communications. The low-frequency converter converts the 10 to 500 kHz LW range to a 1010 to 1550 kHz MW range, by adding 1000 kHz to all received signals. Radio calibration is unnecessary because signals are received at the AM-radio's dial setting, plus 1 MHz; a ...

Light Meter Using I2C Level Converter, LCD, and TSL2561using arduino

I recently needed to measure how different materials affect light transmission for a gardening project.  I decided this was the perfect opportunity to try out the new logic level converter to run both a 5v LCD and a 3.3v light sensor on a single i2c bus.  I used the following parts in this project: Arduino Uno TSL2561 Digital Light Sensor 4-channel I2C Safe Bi-directional Logic Level Converter 16×2 LCD LCD ...

Temperature-to-Bits converter helps solve challenges in sensor measurement

Although temperature is a fundamental aspect of our lives, it is difficult to measure accurately. Before the era of modern electronics, Galileo invented a rudimentary thermometer capable of detecting temperature changes. Two hundred years later, Seebeck discovered the thermocouple, a device capable of generating a voltage as a function of temperature gradients in dissimilar metals. Today, thermocouples as w ...
