    Pocket-Sized Multiduino Does it All
    https://hackaday.com/2018/03/13/pocket-sized-multiduino-does-it-all/

    How many times have you wished for a pocket-sized multimeter? How about a mini microcontroller-based testing rig? Have you ever dared to dream of a device that does both?

    Multiduino turns an Arduino Nano into a Swiss Army knife of portable hacking. It can function as an analog multimeter to measure resistance, voltage drop, and continuity. It can also produce PWM signals, read from sensors, do basic calculator functions, and display the health of its rechargeable battery pack.

    Micro-ATX Arduino is the Ultimate Breakout Board
    https://hackaday.com/2017/12/23/micro-atx-arduino-is-the-ultimate-breakout-board/

    If you’ve been hanging around microcontrollers and electronics for a while, you’re surely familiar with the concept of the breakout board. Instead of straining to connect wires and components to ever-shrinking ICs and MCUs, a breakout board makes it easier to interface with the device by essentially making it bigger. The Arduino itself, arguably, is a breakout board of sorts. It takes the ATmega chip, adds the hardware necessary to get it talking to a computer over USB, and brings all the GPIO pins out with easy to manage header pins.

    But what if you wanted an even bigger breakout board for the ATmega? Something that really had some leg room. Well, say no more, as [Nick Poole] has you covered with his insane RedBoard Pro Micro-ATX. Combining an ATmega32u4 microcontroller with standard desktop PC hardware is just as ridiculous as you’d hope, but surprisingly does offer a couple tangible benefits.

    Stupid Arduinos: The RedBoard Pro Micro-ATX
    They say, “play stupid games, win stupid prizes,” but the joke’s on them: I love stupid prizes.
    https://www.sparkfun.com/news/2561

    The Micro-ATX form factor is compatible not only with Micro-ATX PC cases but also Standard- and Extended-ATX cases. The Pro Micro-ATX conforms to the mechanical specs for footprint size, stand-off placement and expansion card position for the widest possible compatibility across case manufacturers.

    The heart of the Pro Micro-ATX is an ATmega32u4 microcontroller that has been positioned (along with the necessary support components) within the mechanical footprint of an LGA 1151 socket. This gives the user a wide array of options for (pointlessly) cooling the microcontroller, including many AIO air and liquid coolers designed for modern Intel processors.

    Arguably the only useful feature on this board is the 24-pin power connector, which allows the ATmega32u4 and its peripherals to draw from any external, ATX-compatible power supply.

    …but NOT at expansion cards! After all, what’s a motherboard layout without expansion slots? It’s not enthusiast-grade, that’s for sure. So I created a system of expansion cards for the Pro Micro-ATX. It could be argued that the Arduino already has a system of expansion cards — shields — and that they are the best possible expansion system given that they have access to literally every I/O of the host controller. I decided that there was no electrical improvement to be made here and that, instead, adapting the shield system to the ATX form factor would be my main focus. I

    Any good motherboard has rear I/O and the Pro Micro-ATX is no exception. Accessible from the rear panel are a standard shield footprint, a 6-pin Atmel ISP header and a USB type-B connector for serial communication.

    Mechanical specs for ATX and its derivatives are widely published and the topic of a lot of discussion online. This makes it easy enough to grab hold of a dimensioned drawing laying out the card slot, rear I/O and standoff placement. Following these standards allowed me to design a board that fit seamlessly within a random Cooler Master ATX case on the first try.

    USB is tremendously robust

    Take a moment to admire the USB traces leading from the 32u4 to the type-B connector in the rear I/O window. In the words of Sir Mix-A-Lot, “[They’re] long, and [they’re] strong, and [they’re] ready to get the friction on.”

    Arduino goes to space series: A new hope
    https://blog.arduino.cc/2018/03/16/arduino-goes-to-space-series-a-new-hope/

    We recently sponsored one of the labs at Lulea University in Sweden, the INSPIRE (INstrumentation for Space and Planetary Investigation, Resources and Exploration) Lab.

    What I learned rather quickly, thanks to my interactions with both professors over the last couple of years, is that Arduino has been a basic component in the countless projects made in their lab–the Mega and Due are their students’ favorites due to the amount of available pins as well as robustness of the earlier; but also because of the floating comma, analog to digital converter, and general relevance for instrumentation of the latter.

    This article is going to be the first of a series where we will highlight the way the Lulea lab is using Arduino for instruments, real life experiences, zero gravity tests, low orbit missions, and general teaching.

    DIY Visible CT Scanner with a DSLR Camera

    https://blog.hackster.io/diy-visible-ct-scanner-with-a-dslr-camera-c690a43f7f5

    When you think of CT — computed tomography — scanning, your mind automatically jumps to a medical imaging technology that uses a series of X-rays fused together to form a 3D model of a person. This technique can also be accomplished with visible light using the same sort of approach, as long as the object is semi-transparent.

    Arduino Clock Jots Down The Time, In UV
    https://hackaday.com/2018/03/22/arduino-clock-jots-down-the-time-in-uv/

    So when we saw this delightfully complex clock designed by [Tucker Shannon], we instantly fell in love. Powered by an Arduino, the clock uses an articulated arm with a UV LED to write out the current time on a piece of glow-in-the-dark material. The time doesn’t stay up for long depending on the lighting in the room, but at least it only takes a second or two to write out once you press the button.

    Maker Uno Builds on the Arduino Uno at a Price of $6
    https://blog.hackster.io/maker-uno-builds-on-the-arduino-uno-board-at-a-price-of-6-39ae7de6516f

    The Maker Uno — now available on Kickstarter for a discounted price of $4 each — takes the form of an Uno board, but adds some new tricks to enhance functionality. While it features the same digital and analog IO pins as the flagship Arduino, the Maker Uno has 12 LEDs on IO pins 2 to 13, and includes a built-in piezo buzzer. It also has a programmable pushbutton, meaning students and experimenters can get started programming without any extra hardware.

    pedalSHIELD MEGA is a programmable guitar pedal for your Arduino
    https://blog.arduino.cc/2018/03/27/pedalshield-mega-is-a-programmable-guitar-pedal-for-your-arduino/

    The pedalSHIELD MEGA takes input from a guitar via a standard ¼-inch cable, and uses an Arduino Mega to process the sounds to your liking. This new sound is then output using two PWM pins for a 16-bit resolution.

    The device, which is available in kit form or as a PCB, sits on top of the Mega

    Once assembled, all you need to do for an entirely unique sound is program your own effects in the Arduino IDE!

    • Analog Input Stage: The weak guitar signal is amplified and filtered, making it ready for the Arduino Mega ADC (Analog to Digital Converter).

    • Arduino Mega Board: It takes the digitalized waveform from the ADC and does all the DSP (Digital Signal Processing) creating effects (distortion, fuzz, volume, delay, etc).

    • Output Stage: Once the new effected waveform is created inside the Arduino Mega board, this last stage takes it and using two combined PWMs generates the analog output signal.
