ALL BAND RADIO USES ARDUINO AND SI4730

It is getting harder and harder to tell homemade projects from commercial ones. A good case in point is [Mirko’s] all band radio which you can see in the video below the break. On the outside, it has a good looking case. On the inside, it uses a Si4730 radio which has excellent performance that would be hard to get with discrete components. The chip contains two RF strips with AGC, built-in converters to go ...

Arduino 101 Fundamentals

The purpose of this instructable is to introduce the sketch writing fundamentals to all new comers to the Arduino world. It is meant to be a beginners guide that includes detailed explanation about the basic statements and functions. Most of the sketches I use are taken from the Arduino IDE for their simplicity. I wrote this guide when I first started working with Arduino as a way to help me code easier. Fo ...

Arduino controlled Dual Mono AK4490 DAC (part 3)

Following up on Part 2, it’s time to talk about the output stage. This output stage is the brainchild of my friend Kostas, all I did was lay out the PCB. It is a fully discreet single-ended class-A output stage, outputting ~2.4V RMS. This is its schematic: This is the PCB: And this is the BoM: AK4490 dual mono DAC - Discreet Analog stage BOM (509 downloads) The BoM includes part numbers for most parts from ...

Printed circuit board manufacturer – JLCPCB Review

Recently, I had the opportunity to test the printed circuit boards (PCB) offered by JLCPCB. These tests were made in two different boards of the brand and here I’ll report my impressions about them. Due to the spread of the maker culture and the do-it-yourself (DIY) and easy access to components and a huge amount of technical information available on Internet, it has become much simpler to develop a solutio ...

MAKING MUSIC FROM CARDBOARD

Fans of MaKey MaKey may find this project similar, but there’s a lot more to the Mini Automat than making music from fruit. The idea for the Mini Automat (which is an off-shoot of the original Automat project by [Dada Machines]) is to make music accessible to anyone. The device functions as a plug and play MIDI-controller that connects to a computer, MIDI workstation (keyboards and sequencers), or ...
