    Being able to play Atari games like they were meant to be played in the ’80s is really hard today, but possible with the help of an Arduino.

    Don’t Forget Your Mints When Using This Synthesizer
    https://hackaday.com/2018/08/15/dont-forget-your-mints-when-using-this-synthesizer/

    While synthesizers in the music world are incredibly common, they’re not all keyboard-based instruments as you might be imagining. Especially if you’re trying to get a specific feel or sound from a synthesizer in order to mimic a real instrument, there might be a better style synth that you can use. One of these types is the breath controller, a synthesizer specifically built to mimic the sound of wind instruments using the actual breath from a physical person. Available breath controllers can be pricey, though, so [Andrey] built his own.

    To build the synthesizer, [Andrey] used a melodica hose and mouthpiece connected to a pressure sensor. He then built a condenser circuit on a custom Arduino shield and plugged it all into an Arduino Mega

    Analog XY-Plotter Output to HP-GL Translator © MIT
    https://create.arduino.cc/projecthub/johan34/analog-xy-plotter-output-to-hp-gl-translator-7c3e64

    Translate analog XY-plotter output to HP-GL command stream.

    The translator will continually sample the X and Y analog voltages from an oscilloscope’s pen plotter output port, digitize them, and package the values into a series of plain text HP-GL plotter commands, which are output via a USB port to a file on a PC. The HP-GL file can be processed into a display image by any commonly available plotter emulator application, such as PrintCapture (http://www.printcapture.com).

    After a conversation made me think back to the foot controller, I wondered if that there was some simple way to re-create that project, updating it to instead use today’s common USB interface.

    Enter the Arduino Micro, and this project.

    DIY Adjustable Constant Current and Power Load from GreatScott!
    https://blog.hackster.io/diy-adjustable-constant-current-and-power-load-from-greatscott-f4f50dc81d87

    The heart of this device is an IRFZ44N MOSFET on a comically large heat sink. This is driven via a driver module, which is in turn controlled by an Arduino Nano. While the heat sink does look huge compared to the size of the MOSFET itself, considering the design claims to be able to support up to 30V and an impressive 20A of current, one can see why this is necessary.

    The Boldport Cordwood And Cuttlefish, Together As A Guitar Tuner
    https://hackaday.com/2018/08/30/the-boldport-cordwood-and-cuttlefish-together-as-a-guitar-tuner/

    At its heart is a Boldport Cuttlefish ATmega328 development board, and for its display it uses a Cordwood Puzzle as an LED array. All the details are available on a GitHub page, and it’s a modified version of an Arduino guitar tuner he found on Instructables. In particular he’s using a different pre-amp for an electret microphone, and a low-pass filter with a 723Hz cut-off to reduce harmonic content that was confusing the Arduino’s algorithm.

    Luckily, the hacker has enough technology at their disposal these days that DIY test equipment can help fill your bench without emptying your wallet. [Faransky] has created a very impressive Arduino function generator that doesn’t skimp on the features. Capable of generating sine, triangle, and square waves up to 10MHz with its all-digital circuitry, it’s a piece of gear that’s well worth the $30 USD or so it should cost to build your own version.

    Build an Arduino Mega fingerprint door lock
    https://blog.arduino.cc/2018/09/13/build-an-arduino-mega-fingerprint-door-lock/

    The system uses a fingerprint reader to check to see if you have access, and if approved, the device’s Arduino Mega unlocks the theoretical door using a micro servo motor. Three push buttons and a 16×2 LCD screen complete the user interface, and allow more authorized fingers to be added with the main person/finger’s permission.

    Besides security, the build gives a good introduction to Arduino fingerprint scanning, as well as the use of an SD card for data logging functions.

    Create a constant current and power load with Arduino

    If you need a device which draws a certain amount of current and power for testing, then GreatScott! has just the solution.

    His project uses an Arduino Nano, along with a separate IC and a voltage divider, to measure both current and voltage input from the power source. It then employs this data to properly adjust a MOSFET, dissipating the correct amount of voltage and power as required.

    Admit it: when you first heard of the concept of the Unix Epoch, you sat down with a calculator to see when exactly 2³¹-1 seconds would be from midnight UTC on January 1, 1970. Personally, I did that math right around the time my company hired contractors to put “Y2K Suspect” stickers on every piece of equipment that looked like it might have a computer in it, so the fact that the big day would come sometime in 2038 was both comforting and terrifying.

    Connect your Arduino via WebUSB with an web application circuit simulator.

    WebUSB connects remote devices directly to the browser via the web
    A awesome feature in Chrome is support for the WebUSB API, which allows web apps to communicate with USB devices, once user consent is given. This opens up a ton of cool possibilities for the future of web application and hardware interoperability, but may also worry both users and developers when it comes to privacy and security concerns.

    WebUSB requires an Arduino model that gives the sketch complete control over the USB hardware. This library has been tested with the following models:

    Arduino Leonardo
    Arduino/Genuino Micro
