  • cuplTag battery-powered NFC tag logs temperature and humidity (Crowdfunding) - CNX Software

    Temperature and humidity sensors would normally connect to a gateway sending data to the cloud, the coin-cell battery-powered cuplTag NFC tag instead sends data to your smartphone after a tap.

    CulpTag is controlled by an MSP430 16-bit microcontroller from Texas Instruments which reads and stores sensor data regularly into an EEPROM, and the data can then be read over NFC with the tag returning an URL with the data from the sensor and battery, then display everything on the phone’s web browser (no app needed).

  • A first look at Microchip PolarFire SoC FPGA Icicle RISC-V development board - CNX Software

    Formally launched on Crowd Supply a little over a year ago, Microchip PolarFire SoC FPGA Icicle (codenamed MPFS-ICICLE-KIT-ES) was one of the first Linux & FreeBSD capable RISC-V development boards. The system is equipped with PolarFire SoC FPGA comprised a RISC-V CPU subsystem with four 64-bit RISC-V (RV64GC) application cores, one 64-bit RISC-V real-time core (RV64IMAC), as well as FPGA fabric.

    Backers of the board have been able to play with it for several months ago, but Microchip is now sending the board to more people for evaluation/review, and I got one of my own to experiment with. That’s good to have a higher-end development board instead of the usual hobbyist-grade board. Today, I’ll just have a look at the kit content and main components on the board before playing with Linux and FPGA development tools in an upcoming or two posts.

  • What is IoT device management?

    Smart devices are everywhere around us. We carry one in our pocket, watch movies on another while a third cooks us dinner. Every day there are thousands of new devices connecting to the Internet. Research shows that by 2025, more than 150,000 IoT devices will come online every minute. With such vast numbers it is impossible to keep everything in working order just on your own. This brings the need for IoT device management. But what is IoT device management? To answer this question we first need to understand what the Internet of Things (IoT) is.

  • Taking A Deep Dive Into SPI | Hackaday

    With the prevalence of libraries, it has never been easier to communicate with hundreds of different sensors, displays, and submodules. But what is really happening when you type SPI.begin() into the Arduino IDE? In his most recent video, [Ben Eater] explores the Serial Peripheral Interface (SPI) and how it really works.

    Most Hackaday readers probably know [Ben] from his breadboard-based computers, such as the 6502 build we featured in 2019. Since then he has been hard at work, adding new and interesting additions to his breadboard computer, as well as diving into different communication protocols to better understand and implement them. For this video, [Ben] set the goal of connecting the BME280, a common pressure, temperature, and humidity sensor with an SPI interface, to his breadboard 6502 computer. Along the way, [Ben] discusses how exactly SPI works, and why there is so much conflicting nomenclature and operations when looking at different SPI devices.

  • TinySewer is a Portenta-powered camera module for sewer faults detection | Arduino Blog

    We all interact with the sewer system at multiple points throughout the day, and having it fail can lead to catastrophic results. Every year in the United States alone, an estimated 23,000 to 75,000 sewer pipe failures are reported, which means billions of gallons of untreated and hazardous waste is released into the environment. But rather than having a person constantly inspect the system on location, Huy Mai came up with a way to use computer vision in conjunction with embedded machine learning to automatically detect when a defect has occurred.

  • Applying PEP 8

    Two recent threads on the python-ideas mailing list have overlapped to a certain extent; both referred to Python's style guide, but the discussion indicates that the advice in it may have been stretched further than intended. PEP 8 ("Style Guide for Python Code") is the longstanding set of guidelines and suggestions for code that is going into the standard library, but the "rules" in the PEP have been applied in settings and tools well outside of that realm. There may be reasons to update the PEP—some unrelated work of that nature is ongoing, in fact—but Pythonistas need to remember that the suggestions in it are not carved in stone.

  • Purism Librem 5 Linux smartphone is getting another (big) price hike - Liliputing

    The Purism Librem 5 is one of only a handful of smartphones designed to run free and open source GNU/Linux distributions like Purism’s custom PureOS software. It’s also one of the most expensive, currently selling for $899.

    But it’s going to get even more expensive soon. In a move foreshadowed earlier this year, Purism recently announced that prices will go up this fall due at least in part to rising supply chain costs due to the global chip shortage. Customers who place an order after November 1, 2021 will have to pay $1199. And in March, 2022 the price will go up to $1299.

  • Harp Uses Frikin’ Lasers | Hackaday

    We aren’t sure if you really need lasers to build [HoPE’s] laser harp. It is little more than some photocells and has an Arduino generate tones based on the signals. Still, you need to excite the photocells somehow, and lasers are cheap enough these days.

    Mechanically, the device is a pretty large wooden structure. There are six lasers aligned to six light sensors. Each sensor is read by an analog input pin on an Arduino armed with a music-generation shield. We’ve seen plenty of these in the past, but the simplicity of this one is engaging.

  • Take a Look at This Optical Keyboard

    Making keyboards is easy, right? Just wire up a bunch of switches matrix-style to a microcontroller, slap some QMK and a set of keycaps on there and you’re good to go. Well, yeah, that might work for cushier environments like home offices and Hackaday dungeons, but what if you need to give input under water, in a volatile area, or anywhere else you’d have to forego the clacking for something hermetically sealed? Mechanical switches can only take you so far — at some point, you have to go optical.

  • The Many Ways To Solve Your Enclosure Problems | Hackaday

    Most projects around here involve some sort of electronics, and some sort of box to put them in. The same is true of pretty much all commercially available electronic products as well.

    Despite that, selecting an enclosure is far from a solved problem. For simple electronics it’s entirely possible to spend more time getting the case just right than working on the circuit itself. But most of the time we need to avoid getting bogged down in what exactly will house our hardware.

    The array of options available for your housing is vast, and while many people default to a 3D printer, there are frequently better choices. I’ve been around the block on this issue countless times and wanted to share the options as I see them, and help you decide which is right for you. Let’s talk about enclosures!

Raspberry Pi created a revolution when it launched the $25 mini computer ten years ago. Over the time, several variants of Raspberry Pi have been launched. Some upgrade a previous model and some are crafted for specific purposes.

Of all the Raspberry models, Pi Zero and Pi Zero W are the cheapest ones aimed for small scale and IoT projects. Both devices are almost similar to each other but with a subtle and important difference.

So, what is the difference between Raspberry Pi Zero and Zero W? The W in Zero W stands for Wireless and it depicts its wireless capability over the Pi Zero model. That’s the single biggest difference between the two similar models.

  • Firmware Modding Your Vintage Nokia Handset

    These days we’re spoiled for choice when it comes to smartphone software, especially games. Official repositories for the leading handsets feature hundreds of thousands of games, and sideloading adds infinite possibilities. If you were lucky enough to be sporting a Nokia handset in the late 1990s, you probably had all of three games to choose from (and only one that was actually fun). [Janus Cycle] explores the steps needed to firmware mod your vintage Nokia phone, and how to expand on that paltry games library.

    Enthusiasts have been modding their Nokia handsets since the 2000s, and the tools required now are the same as they were then. The Nokia 5110 and 6110 (as featured in the video below) use a proprietary cable and connector for communicating with PCs and other devices. Nokia’s official serial cable already opens up many possibilities for handset tinkering, including access to RAM and toggling Monitor Mode. This cable interfaces solely with the phone’s fast FBUS protocol, however firmware flashing takes place using the slower MBUS protocol over a single wire bi-directional pin.

  • Announcement : An AArch64 (Arm64) Darwin port is planned for GCC12

    As many of you know, Apple has now released an AArch64-based version of macOS and desktop/laptop platforms using the ‘M1’ chip to support it. This is in addition to the existing iOS mobile platforms (but shares some of their constraints). There is considerable interest in the user-base for a GCC port (starting with https://gcc.gnu.org/bugzilla/show_bug.cgi?id=96168) - and, of great kudos to the gfortran team, one of the main drivers is folks using Fortran. Fortunately, I was able to obtain access to one of the DTKs, courtesy of the OSS folks, and using that managed to draft an initial attempt at the port last year (however, nowhere near ready for presentation in GCC11). Nevertheless (as an aside) despite being a prototype, the port is in use with many via hombrew, macports or self-builds - which has shaken out some of the fixable bugs. The work done in the prototype identified three issues that could not be coded around without work on generic parts of the compiler. I am very happy to say that two of our colleagues, Andrew Burgess and Maxim Blinov (both from embecosm) have joined me in drafting a postable version of the port and we are seeking sponsorship to finish this in the GCC12 timeframe. Maxim has a lightning talk on the GNU tools track at LPC (right after the steering committee session) that will focus on the two generic issues that we’re tackling (1 and 2 below). Here is a short summary of the issues and proposed solutions (detailed discussion of any of the parts below would better be in new threads).

    Developers are hoping for next year's GCC 12 release they will have Apple AArch64 support on Darwin in place for being able to support Apple Silicon -- initially the M1 SoC -- on macOS with GCC. LLVM/Clang has long been supporting AArch64 on macOS given that Apple leverages LLVM/Clang as part of their official Xcode toolchain as the basis for their compiler across macOS to iOS and other products. While the GNU Compiler Collection (GCC) supports AArch64 and macOS/Darwin, it hasn't supported the two of them together but there is a port in progress to change it.
