This tiny little board does all of the neat Arduino tricks that you're familiar with: nine channels of 10-bit ADC, five PWM pins, 12 DIOs as well as hardware serial connections Rx and Tx. Running at 5 V and 16 MHz, this board will remind you a lot of your other favourite Arduino-compatible boards, but this little guy can go just about anywhere. There is a voltage regulator on board so it can accept voltage up to 6 VDC. If you're supplying unregulated power to the board, be sure to connect to the 'RAW' pin on not VCC. The reset button's benefit is to quickly reset the board or place it into bootloader mode without the need to take out a piece of the jumper wire. The USB micro-b connector has been replaced with the USB type C connector. The through-hole pads have castellated edges for each pin to add a lower profile in your projects should you decide to build it into another assembly during production. Finally, a Qwiic connector is populated on the board's bottom to add Qwiic enabled I²C devices to your projects easily!

Quite unintentionally a one-page story on an old Heathkit tube tester in the December 2004 edition of Elektor magazine spawned dozens of ‘Retronics’ tales appearing with a monthly cadence, and attracting a steady flow of reader feedback and contributions to the series. Since launching his Retronics columns, Elektor Editor Jan Buiting has never been short of copy to print, or vintage equipment to marvel at. This book is a compilation of about 80 Retronics installments published between 2004 and 2012. The stories cover vintage test equipment, prehistoric computers, long forgotten components, and Elektor blockbuster projects, all aiming to make engineers smile, sit up, object, drool, or experience a whiff of nostalgia. To reflect that our memories are constantly playing tricks on us, and honoring that “one man’s rubbish is another man’s gem”, the tales in the book purposely have no chronological order, and no bias in favor of transistor or tube, microprocessor or discrete part, audio or RF, DIY or professional, dry or narrative style. Although vastly diff erent in subject matter, all tales in the book are told with personal gusto because Retronics is about sentiment in electronics engineering, construction and repair, be it to reminisce about a 1960s Tektronix scope with a cleaning lady as a feature, or a 1928 PanSanitor box for dubious medical use. Owners of this book are advised to not exceed one Retronics tale per working day, preferably consumed in the evening hours under lamp light, in a comfortable chair, with a piece of vintage electronic equipment close and powered up.

Raspberry Pi cooling is a must. From the simplest passive heat sink, through elaborate fan blowers and even to an exotic water-cooled idea, many options are available. Sequent Microsystems Smart Fan has the form factor of the Raspberry Pi HAT. Its own tinny 32-bit processor receives commands from Raspberry Pi through the I²C interface. A step-up power supply converts the 5 V provided by Raspberry Pi to 12 V, ensuring precise speed control. Using pulse width modulation, it powers the fan just enough to maintain a constant temperature of the Raspberry Pi processor. The Smart Fan preserves all the GPIO pins, allowing any number of cards to be stacked on top of Raspberry Pi. If another add-on card has to dissipate power, a secondary Smart Fan can be added to the stack. DIN-Rail Mounting Together with multiple add-on cards, the Smart Fan can be installed on the DIN-Rail, for sturdy industrial applications. Stack Level Jumper Two Smart Fans can be installed on top of each Raspberry Pi. The assumption is that you have one more card in the stack which requires cooling. The bottom side of the Smart Fan has a jumper which needs to be installed on the second fan, in order for the Raspberry Pi to differentiate the two I²C addresses. Features 40 x 40 x 10 mm fan with 6 CFM airflow Step-up 12 V power supply for precise fan speed control PWM Controller modulates the fan to keep constant Pi temperature Draws less than 100 mA of power Stackable to itself, 2 fans can be added to Raspberry Pi Fully stackable allows adding other cards to Raspberry Pi Uses only I²C interface, leaves full use of all GPIO pins Super quiet and efficient Included Smart Fan HAT 40 x 40 x 10 mm Fan with mounting Screws Mounting Hardware Downloads User's Guide Open Source Hardware Schematic 2D CAD Drawing Command line Python Libraries Node-Red Nodes

The SparkFun Qwiic OpenLog is the smarter and better looking cousin to the extremely popular OpenLog but now we've ported the original serial based interface to I²C! Thanks to the added Qwiic connectors, you can daisy chain multiple I²C devices and log them all without taking up your serial port. The Qwiic OpenLog can store, or 'log', huge amounts of serial data and act as a black box of sorts to store all the data that your project generates, for scientific or debugging purposes. Utilizing our handy Qwiic system, no soldering is required to connect it to the rest of your system. However, we still have broken out 0.1'-spaced pins in case you prefer to use a breadboard. Like its predecessor, the SparkFun Qwiic OpenLog runs off of an onboard ATmega328, running at 16 MHz thanks to the onboard resonator. The ATmega328 has been sure to feature the Optiboot bootloader loaded, which allows the OpenLog to be compatible with the “Arduino Uno” board setting in the Arduino IDE. It is important to be aware that the Qwiic OpenLog draws approximately 2 mA-6 mA in idle (nothing to record) mode, however, during a full record the OpenLog can draw 20 mA to 23 mA depending on the microSD card being used. The Qwiic OpenLog also supports clock stretching, which means it performs even better than the original and will record data up to 20,000 bytes per second at 400 kHz. As the receive buffer fills up this OpenLog will hold the clock line, letting the master know that it is busy. Once the Qwiic OpenLog is finished with a task, it releases the clock thus allowing the data to continue flowing without corruption. For even better performance the OpenLog Artemis is the tool you need, featuring logging speeds up to 500000 bps. Features Continuous data logging at 20,000 bytes per second without corruption Compatible with high speed 400 kHz I²C Compatible with 64 MB to 32 GB microSD cards (FAT16 or FAT32) Preloaded Uno bootloader so upgrading the firmware is as easy as loading a new sketch Valid I²C Addresses: 0x08 to 0x77 2x Qwiic Connectors Downloads Schematic Eagle Files Hookup Guide Arduino Library GitHub

The Data Logging Carrier Board breaks out connections for I²C via a Qwiic connector or standard 0.1'-spaced PTH pins along with SPI and serial UART connections for logging data from peripheral devices using those communication protocols. The Data Logging Carrier Board allows you to control power to both the Qwiic connector on the board and a dedicated 3.3 V power rail for non-Qwiic peripherals so you can pick and choose when to power the peripherals you are monitoring the data from. It also features a charging circuit for single-cell Lithium-ion batteries along with a separate RTC battery-backup circuit to maintain power to a real-time clock circuit on your Processor Board. Features M.2 MicroMod Connector microSD socket USB-C Connector 3.3 V 1 A Voltage Regulator Qwiic Connector Boot/Reset Buttons RTC Backup Battery & Charge Circuit Independent 3.3 V regulators for Qwiic bus and peripheral add-ons Controlled by digital pins on Processor Board to enable low power sleep modes Phillips #0 M2.5 x 3 mm screw included

Using the RFID Starter Kit An Arduino board has now become ‘the’ basic component in the maker community. No longer is an introduction to the world of microcontrollers the preserve of the expert. When it comes to expanding the capabilities of the basic Arduino board however, the developer is still largely on his own. If you really want to build some innovative projects it’s often necessary to get down to component level. This can present many beginners with major problems. That is exactly where this book begins. This book explains how a wide variety of practical projects can be built using items supplied in a single kit together with the Arduino board. This kit, called the 'RFID Starter Kit for Arduino' (SKU 17240) is not just limited to RFID applications but contains more than 30 components, devices and modules covering all areas of modern electronics. In addition to more simple components such as LEDs and resistors there are also complex and sophisticated modules that employ the latest technology such as: A humidity sensor A multicolor LED A large LED matrix with 64 points of light A 4-character 7-segment LED display An infra red remote-controller unit A complete LC-display module A servo A stepper motor and controller module A complete RFID reader module and security tag On top of that you will get to build precise digital thermometers, hygrometers, exposure meters and various alarm systems. There are also practical devices and applications such as a fully automatic rain sensor, a sound-controlled remote control system, a multifunctional weather station and so much more. All of the projects described can be built using the components supplied in the Elektor kit.

The State of Hollow State Audio in the Second Decade of the 21st Century Vacuum-tube (or valve, depending upon which side of the pond you live on) technology spawned the Age of Electronics early in the 20th Century. Until the advent of solid-state electronics near mid-century, hollow-state devices were the only choice. But following the invention of the transistor (after their process fell to reasonable levels), within a couple of decades, the death of vacuum tubes was widely heralded. Yet here we are some five decades later, and hollow-state equipment is enjoying something of a comeback, especially in the music and high-end audio industries. Many issues surround hollow-state audio: Does it produce—as some claim—better sound? If so, is there science to back up these claims? How do hollow-state circuits work? How do you design hollow-state audio circuits? If hollow-state equipment fails, how do you go about troubleshooting and repairing it? Can we recreate some of the classic hollow-state audio devices for modern listening rooms and recording studios? How can we intelligently modify hollow-state amplifiers to our taste? These and other topics are covered in The State of Hollow State Audio.
