    Opta: Enhanced cybersecurity after HWG Sababa’s testing

    Reading Time: 2 minutes

    Connecting machines and equipment to the internet became easier than ever when we launched the Arduino Opta micro PLC, enabling real-time control, monitoring, predictive maintenance and more – in industries ranging from smart agriculture to large-scale manufacturing to building automation. 

    Supporting our well-known Arduino sketch programming experience and any of the five IEC 61131-3 PLC standard languages, the Opta was designed to be powerful yet easy to use from the start – as well as highly secure. Indeed, the Opta supports OTA firmware updates and ensures data security from the hardware to the Cloud thanks to the physical onboard secure element and X.509 Standard compliance. 

    In addition, as part of the go-to-market for this innovative hardware solution, we actively committed to verifying its security against the threats posed by cyberattacks. 

    To this end, in late 2023 we started a collaboration with global cybersecurity provider HWG Sababa: their Offensive Team engaged in a penetration test that lasted weeks, assessing Opta’s security posture and pinpointing any weaknesses. Their meticulous report allowed us to remedy any vulnerabilities before they became actual issues, and now we are proud to say the Opta is more secure than ever.

    The software patches and configuration updates we carried out are part of our ongoing commitment to providing you the most robust solutions on the market in every respect – including against ever-evolving cyber threats. The rigorous testing process and following activities our team completed only confirms Opta as an ideal candidate for any industrial automation project you have in mind.

  • The Hardware-Oriented Microprocessor Simulator illustrates the inner workings of microcontrollers

    The Hardware-Oriented Microprocessor Simulator illustrates the inner workings of microcontrollers

    Reading Time: 2 minutes

    Do you really understand what is happening within the mysterious black packaging of a microcontroller or microprocessor? Most people don’t — we just learn how to use them. That’s because they’re wildly complex circuits combining many different subsystems that are all abstracted away from the view of the user. To help students better understand these integrated circuits (ICs), Dr. Panayotis Papazoglou designed the Hardware-Oriented Microprocessor Simulator (HOMS)

    Dr. Papazoglou is an associate professor at the National and Kapodistrian University of Athens (NKUA), so he has a stake in creating an educational tool like this one. The goal of HOMS is to provide a visual and tactile demonstration of what happens inside an eight-bit microprocessor. For example, it will show a value moving from a counter to a memory register. That’s something that is difficult to visualize when using a microprocessor, even if you’re working close to “the metal” in assembly. 

    HOMS is a modular system, so students can experiment with blocks that represent different subsystem circuits within a microprocessor. Each module has an Arduino UNO Rev3 board to control its own functions, with all of the modules working under the coordination of a central Arduino Mega 2560 controller. One module may, for instance, represent memory and will show the data “written” to it on a display. Another module may have buttons and switches to allow user input.

    There are software simulation tools that seek to illustrate computing fundamentals in a similar way, but many people learn better through physical interaction. For those people, HOMS could be very helpful.

  • Not bigger, just better: Introducing the Nano 33 BLE Rev2

    Not bigger, just better: Introducing the Nano 33 BLE Rev2

    Reading Time: 2 minutes

    The Nano 33 BLE is one of our most popular boards, and for good reason. It’s small and 3.3-V-compatible; it comes with an embedded nine-axis IMU featuring accelerometer, gyroscope and magnetometer; it has a powerful processor; it offers a powerful Bluetooth® Low Energy module with an internal antenna that can be used to transmit data between different devices using the ArduinoBLE library; and it can be programmed with MicroPython. 

    It’s basically everything you need for projects that span from wearable to advanced robotics. 

    So, why work on making it better?

    Because we listen to our community, that’s why. And based on your requests, we’ve come up with improvements to enhance your experience with a revised iteration of the Arduino Nano 33 BLE with a newly integrated IMU to expand experimentation possibilities, and a streamlined PCB design to grant easy access to essential features.

    And here is exactly what you can find in the new Rev2, compared to its predecessor:

    • It has a combination of two IMUs (BMI270 six-axis IMU plus BMM150 three-axis IMU) instead of a single, nine-axis one.
    • While retaining the compact form factor, the new Nano 33 BLE Rev2 incorporates new pads and test points for USB, SWDIO, and SWCLK, making it easier to access these crucial points on the board.
    • We introduced a new VUSB soldering jumper on the top side, allowing you to conveniently enable the VUSB pin while using the castellated pins.
    • In addition, the Nano 33 BLE Rev2 transitions the power supply component to the MP2322 to guarantee increased performance. 

    These updates collectively contribute to a more streamlined and robust device, ready for you to test and build just about any IoT project – and more. For example, the Nano 33 BLE Rev2 is still ideal to control RGB LEDs over Bluetooth®, using an app on your phone, and supports OpenMV’s fork of MicroPython

    If you already know the Nano 33 BLE from its first revision, you can easily migrate your sketches to use them with the new and improved version: if you need help, just follow our dedicated tutorial.

    After the launch of the Nano ESP32 earlier this year, it’s the perfect addition to the “tiny footprint, mighty features” family that has proven time and time again that we can ramp up features and performance while scaling down size. Don’t believe us? Check out the classic Arduino Nano or upgrade to the Nano 33 BLE Sense Rev2 if you want to include a complete set of sensors, too. 

    For full tech specs, tutorials and inspiration on the Nano 33 BLE Rev2, head to the dedicated Arduino Docs page. Ready to get your own? The Nano 33 BLE with headers and without headers are now available on our Store.

  • Black role models in tech are making history every day

    Black role models in tech are making history every day

    Reading Time: 5 minutes

    It’s the last week of Black History Month 2024 in the USA, but by no means is the celebration over. The beautiful thing about history is that it’s not an isolated narrative about the past, but an ongoing dialogue in which we talk about how our collective past informs our present, and what more can be achieved in the future. The fact is this: we make history every single day. That’s why it’s so important for everyone to actively engage with history, and for us to celebrate the achievements of all.

    A young person with their project at a Coolest Projects event.

    When we talk about the history of STEM and computing, it’s necessary to highlight the achievements of people from groups that are still underrepresented in these fields: communities of colour, female and gender non-conforming people, people with disabilities, and underresourced communities. When we highlight their achievements, everyone can gain a fuller understanding of this history, and more young people from these groups can see they have a place in these fields and in moving them forward. 

    [When young kids of colour help inform the technology they use,] we end up with technology that is more inclusive to diverse communities […], and we help the kids become creators instead of just consumers.

    Qumisha Goss

    So to keep the conversation going about Black history in STEM and computing and how people make it every day, today we’re highlighting stories of Black community members. You’ll find out how they got involved in coding and creating with technology, and who their Black role models in tech are — past and present.

    Community spotlight: Qumisha Goss

    Meet Qumisha Goss, a brilliant source of inspiration and a shining light for youth in the ‘Motor City’ of Detroit, Michigan, USA.

    A smiling woman.

    Growing up, Qumisha always had an interest in tech, often tinkering and putting projects together, and her interest quickly transformed into a dream of becoming an engineer one day. Fast forward to now, and Qumisha has done exactly that and so much more.

    She’s the Interim Executive Director of Peer 2 Peer University, the Digital Literacy Subject Matter Expert for Connect 313, the Creator and Lead Instructor of Code Grow, and a Raspberry Pi Certified Educator. Talk about impact! We asked Qumisha a few questions to explore her incredible story and to learn how she’s giving back to her community today: 

    Which Black individuals have helped pave the way for you?

    Qumisha: “When I was a kid, my grandmas, Gloria and Cassandra, helped my brother and I make a shrinking machine out of a cardboard box, some batteries, and some lights. There was a minimum of science used, but my grandma swapped out our test ear of corn for a baby corn and my curiosity was rewarded with success. In elementary school, my ‘hero’ was Mae Carol Jemison, engineer, doctor, and astronaut. She was the first African American woman to go to space, in 1992 on the Endeavor. I found someone who looked like me who was doing something that I wanted to do, and that was encouraging.”

    Two young people using laptops at a Code Club session.

    Why is it important to encourage diversity in tech?

    Qumisha: “It’s important that young kids of colour help inform the technology that they use. The benefits are twofold: we end up with technology that is more inclusive to diverse communities because it is informed by them, and we help the kids become creators instead of just consumers.”

    How did you find your way into tech?

    Qumisha: “I eventually went to college to study engineering. I ended up switching majors and studying history and classical languages, but later returned to the tech world when I joined the Python and Raspberry Pi communities. I learned how to code outside of a traditional classroom and have been running physical computing classes and workshops for kids in my hometown of Detroit.”

    A Coolest Projects participant

    How do you believe your work is paving the way for more Black excellence in tech?

    Qumisha: “Even if kids don’t stick with it, they learn that coding — and lots of things — are not beyond them. The next Bill Gates might be sitting on the library stoop. The difference between them being able to make it or not is: ‘Did they ever get the opportunity to touch the thing that really sparks their genius?’ And for me, I want to help as many kids as possible interact with tech in a fun and engaging way so that they know that they can be technologists too.”

    The difference between [kids] being able to make it or not is: ‘Did they ever get the opportunity to touch the thing that really sparks their genius?’

    Qumisha Goss

    To connect with Qumisha and learn how you can support the incredible, history-making work that she’s doing, follow her on X at @QatalystGoss.

  • UNO R4 Stars: Meet Clatters Machines

    UNO R4 Stars: Meet Clatters Machines

    Reading Time: 2 minutes

    The launch of the Arduino UNO R4 marks a huge leap forward for our community. For us, it’s also the chance to celebrate the people who bring our ecosystem to life with their bright ideas, radiant enthusiasm, and shining insight.

    That is how the UNO R4 Stars blog post series began: to highlight makers who have not only created amazing projects with Arduino, but who are giving back to the community by sharing as they go and helping others make anything they wish.

    We invite you to discover each profile, hoping you might find a North Star to navigate around an expanding galaxy or venture into completely new universes.

    Clatters Machines creates “noisy machines for music lovers” – handmade electronic musical instruments that turn technology into sound waves. The company was co-founded by Carolina Guidi and Michelangelo Nasso, brought together by a unique passion for sound and for making what could be a mess of cables, wires, and knobs look really cool. 

    Guidi, in particular, is in charge of visual branding and product design – which makes for great eye candy on their Instagram wall! – while Nasso’s favorite part of the job is prototyping and testing the modules, fueled by his passion for hardware and software engineering.

    Arduino has always played a crucial role in the duo’s explorations, and later, in their work. Guidi discovered the brand during a university workshop: she says she was surprised to find out that putting together a few components on a breadboard could be so easy and accessible – “all you need to worry about is your own creativity.” 

    Nasso got his first taste of Arduino a bit earlier, quickly realizing how it made a lot of his ideas closer to reality than he thought, even before he acquired the engineering skills he would develop during university. 

    It is not by chance that their very first product, the Pocket Garden Listener, was “all designed, prototyped and tested with an Arduino UNO,” and that they have fond memories of the experience.

    The embodiment of how creative flair and engineering mastery can come together beautifully, Clatters Machines takes pride in inspiring “people who play and love music, with products that start right here, from an original idea:” isn’t that the essence of making?

    [youtube https://www.youtube.com/watch?v=Cnk_oSLKq8Y?feature=oembed&w=500&h=281]

    We asked Guidi and Nasso, “What’s your favorite part of the UNO R4?”

    • Its thrilling potential, which opens up to infinite new possibilities – just like the very first Arduino UNO did for the many makers who started with it! 
    • The huge leap forward it represents for anyone working in prototyping, thanks to the upgraded tech specs.
    • How it “ramps up everything that made Arduino the brand it is today.’

  • 8BitDo Retro Mechanical Keyboard

    8BitDo Retro Mechanical Keyboard

    Reading Time: 3 minutes

    8BitDos latest offering (£79/$100) bucks this trend. A pair of beautiful wireless mechanical keyboards with colour schemes based on the original NES and Famicom, the most noticeable thing about them is an included pair of gigantic ‘super buttons’, arcade-esque add-ons that plug into the keyboard and can be programmed to run certain keys or macros.

    Playing with power

    If you’ve used any 8BitDo input device before, you’ll know that you can press a specific macro button to assign a keypress manually to these buttons, along with very conspicuous A and B buttons next to the space bar. In our mind, the intended use of this is either shortcuts on the desktop, or to assign custom keys for a more accurate experience on some retro games via RetroPie. Unlike other controllers and keyboards, you can’t set up these extra super buttons inside RetroPie but it will recognise the inputs you’ve set to it from using the macro button, or via a custom ‘profile’ that’s set up on another machine.

    The software is fairly easy to use although it does allow for a lot of customisation

    The customisation software, called 8BitDo Ultimate Software V2 is very powerful, allowing you to not only assign keys and/or macros to the super buttons, but also completely remap the keyboard as well – including adding special navigation or media control functions, which is very fancy. Creating macros is very deep as well, allowing you to pull off long combos with custom delay between button presses too. It’s an astounding amount of customisation, although unfortunately the software is only available on Windows PCs right now. Still, you can turn the customisation on and off with a simple press of the keyboards profile button, so once you have set it up on a PC you don’t need to remain connected to it.

    Hook it up

    The connection options are great – as well as a classic wired connection via the USB-C charging port, you can connect via Bluetooth or a 2.4GHz RF stick stored away on the underside. We found initially connecting the keyboard via Bluetooth had some issues, but once connected it worked just fine. The 2.4GHz stick worked right away and is currently out preferred way to use it. There’s a satisfying clunky switch that goes between the different radio types which perfectly complements the comfy and clicky keys on the keyboard. We had no lag on any games we played on RetroPie, and the super buttons were very fun to smash for that.

    The super buttons connect via a 3.5mm jack just like peripherals on accessible game controllers, and are very satisfying to use

    The switches and keys are standard PCB/PBT types so you can swap them out if you have preferred keys or want a quieter type (we have been banned from using them at Pi Towers due to the noise, oops).

    There is currently only a US layout, and despite the Japanese symbols on the Famicom version, it’s missing one or two keys to be a full Japanese keyboard. It is just an aesthetic choice though, and the design of the keys and labelling elsewhere is authentic and very pretty.

    Verdict

    9/10

    A very good retro keyboard for retro gaming, although you can’t unlock its full features with just a Raspberry Pi.

  • Building your own affordable SCARA plotter with Arduino

    Building your own affordable SCARA plotter with Arduino

    Reading Time: 2 minutes

    Robots come in all shapes and sizes, but one of the most popular styles for industrial applications is the SCARA (Selective Compliance Assembly Robot Arm). These have multiple degrees of freedom, each of which rotates around the vertical Z axis. But they’re otherwise constrained, which can have advantages for certain applications. For example, they tend to have relatively high payload capacities. If you’re on a budget but want to dip your toes in, tuenhidiy’s SCARA plotter is a great way to start.

    This is a follow-up to tuenhidiy’s previous SCARA design from a couple of years ago. The new version is more robust and includes a homing feature, which is important for repeatability. This is set up as a plotter and the firmware reflects that, but it would be possible to adapt the mechanical design for other purposes. 

    To keep costs down, most of the structure is PVC pipe. Stepper motors provide actuation via GT2 timing belts and pulleys. An Arduino Mega 2560 board controls those steppers through a RAMPS 1.4 board with A4988 stepper drivers. An interface module with a 2004 LCD, rotary encoder, buzzer, and button lets the user start jobs.

    In this case, those jobs are G-code files containing the movement commands to reproduce the drawings. That works because the Arduino runs Marlin firmware (popular in the 3D printing community). The use of Marlin made homing easy and it accepts g-code that users can create with most of the standard software tools.

    These custom Chucks are smokin’ hot kicks

    Reading Time: 2 minutes

    Once you get bored with the shoes on the shelves at Payless, you can dive into the fascinating world of custom sneakers. Converse Chuck Taylors are probably the most popular canvas for shoe customizers, as they offer plenty of room for paint and jewel bedazzling. But creative technologist Tigris Li took it to a whole other level with her Chuck 70s Smoke Shoes that blow clouds as the wearer walks.

    Each shoe has an apparatus that looks like it was cobbled together by a mad scientist trying invent their way into dunking. When the wearer puts pressure down on the sole, that apparatus will puff out a cloud of smoke. Those soles are actually custom, too. Li 3D-printed them in TPU to give the shoes a cool, angular look. They also contain the force sensors that trigger the smoke production.

    An Arduino Nano ESP32 board in each shoe monitors the force sensor in the sole. When the signal surpasses a set threshold, the Arduino activates a relay that allows power to flow through a heating coil. That coil sits in smoke machine fluid that comes from a tiny flask attached to the shoe. With power flowing, the coil burns the fluid and that expands to create the smoke.

    We can only assume that we’ll see Jay-Z wearing these at his next appearance at the Grammy Awards.

  • The ultimate lighting system for model railroaders

    The ultimate lighting system for model railroaders

    Reading Time: 2 minutes

    Go to any model railroading convention and you’ll see that most layouts have far more work put into the terrain and buildings than into the trains themselves. The emphasis is usually on realism, so enthusiasts spend uncountable hours constructing and weathering their buildings. But lighting those buildings can be difficult, leading many people choose simple static lighting. This project by Olivier Wagener makes it relatively easy to upgrade that lighting to something much more sophisticated.

    Wagener started this project to help his father improve the lighting of a train station building for his model railroad. The result is really impressive, because every room in the building has two of its own LEDs: one a warm temperature and one a cool temperature. This also supports RGB LEDs. Using a smartphone, the user can set the brightness, color, and temperature of each room individually. They can also group those into zones for quick control. Once setup, the user has complete control over the realistic lighting and that adds a whole new dimension to model railroading.

    This is possible thanks to an Arduino MKR 1010 WiFi board that communicates with Wagener’s custom app over the local network. This can handle up to 976 single-color LEDs (warm or cool), 305 RGB LEDs, or some combination of the two. To give the Arduino full PWM (pulse-width modulation) control over that many LEDs, Wagener chose PCA9685 PWM module boards. Each one has 16 channels, so a full set of 976 single-color LEDs will require 61 boards. 305 RGB LEDs will also require 61 boards, because each of those LEDs takes up three channels.

  • Adam Cohen-Rose interview

    Adam Cohen-Rose interview

    Reading Time: 3 minutes

    What is your history with making?

    I’ve always enjoyed building things – I had a big chest of LEGO as a kid, and so did my wife, and now we’ve only expanded it as our children got into model building too!

    I’ve been going to BarCamps and hackathons since 2007 and have loved the opportunity to work with other people to put something together in a short space of time. I was even featured on BBC Click as an ‘Inventor’ back in 2009 for building a LEGO Dalek controlled from my phone.

    The maze game on the Astro Pi – it’s a bit small, but so is the screen it’s displayed on.

    When did you learn about Raspberry Pi?

    Pretty early on. My then 12-year-old (now 20!) was one of the judges at the Code Club Pi-hack back in December 2012.

    I’ve three active Raspberry Pi [boards] in the house, plus about seven or eight others, connected or embedded in various projects.

    This displays temperature and humidity, so during the demo people can figure out how the Sense HAT works.

    How did you start with Code Club?

    I started running a programming club in my child’s primary school back in February 2012 – just before Code Club was founded. I approached the head teacher to offer a free lunchtime club for year 4s and he jumped at the idea!

    Once the Code Club Scratch projects came out, I switched to using them pretty quickly as they were great fun and the children really enjoyed making their own games.

    We’ve now had Code Clubs at Fleetville Junior School for nearly 12 years. I’m still running the year 6 club, even though neither of my kids go there any more! And we also run lunchtime clubs for years 4 and 5 – using Code Club material as well as Minecraft Education, micro:bits and Machine Learning for Kids.

    I’ve also started up Code Clubs at work: Tesco Technology supports two clubs – one lunchtime club by our Welwyn office, and one after-school club by our London office.

    What are some of your favourite Astro Pi moments?

    Getting the kids to guess what the sensors are on my 3D-printed Astro Pi mockup – I run a small program that displays a maze for the gyroscope and accelerometer, and a bar graph for the humidity and temperature sensors. The kids then have to try different inputs to figure out what they are responding to. See the code and some pictures here.

  • Supporting learners with programming tasks through AI-generated Parson’s Problems

    Supporting learners with programming tasks through AI-generated Parson’s Problems

    Reading Time: 6 minutes

    The use of generative AI tools (e.g. ChatGPT) in education is now common among young people (see data from the UK’s Ofcom regulator). As a computing educator or researcher, you might wonder what impact generative AI tools will have on how young people learn programming. In our latest research seminar, Barbara Ericson and Xinying Hou (University of Michigan) shared insights into this topic. They presented recent studies with university student participants on using generative AI tools based on large language models (LLMs) during programming tasks.

    Using Parson’s Problems to scaffold student code-writing tasks

    Barbara and Xinying started their seminar with an overview of their earlier research into using Parson’s Problems to scaffold university students as they learn to program. Parson’s Problems (PPs) are a type of code completion problem where learners are given all the correct code to solve the coding task, but the individual lines are broken up into blocks and shown in the wrong order (Parsons and Haden, 2006). Distractor blocks, which are incorrect versions of some or all of the lines of code (i.e. versions with syntax or semantic errors), can also be included. This means to solve a PP, learners need to select the correct blocks as well as place them in the correct order.

    A presentation slide defining Parson's Problems.

    In one study, the research team asked whether PPs could support university students who are struggling to complete write-code tasks. In the tasks, the 11 study participants had the option to generate a PP when they encountered a challenge trying to write code from scratch, in order to help them arrive at the complete code solution. The PPs acted as scaffolding for participants who got stuck trying to write code. Solutions used in the generated PPs were derived from past student solutions collected during previous university courses. The study had promising results: participants said the PPs were helpful in completing the write-code problems, and 6 participants stated that the PPs lowered the difficulty of the problem and speeded up the problem-solving process, reducing their debugging time. Additionally, participants said that the PPs prompted them to think more deeply.

    This study provided further evidence that PPs can be useful in supporting students and keeping them engaged when writing code. However, some participants still had difficulty arriving at the correct code solution, even when prompted with a PP as support. The research team thinks that a possible reason for this could be that only one solution was given to the PP, the same one for all participants. Therefore, participants with a different approach in mind would likely have experienced a higher cognitive demand and would not have found that particular PP useful.

    An example of a coding interface presenting adaptive Parson's Problems.

    Supporting students with varying self-efficacy using PPs

    To understand the impact of using PPs with different learners, the team then undertook a follow-up study asking whether PPs could specifically support students with lower computer science self-efficacy. The results show that study participants with low self-efficacy who were scaffolded with PPs support showed significantly higher practice performance and higher problem-solving efficiency compared to participants who had no scaffolding. These findings provide evidence that PPs can create a more supportive environment, particularly for students who have lower self-efficacy or difficulty solving code writing problems. Another finding was that participants with low self-efficacy were more likely to completely solve the PPs, whereas participants with higher self-efficacy only scanned or partly solved the PPs, indicating that scaffolding in the form of PPs may be redundant for some students.

    Secondary school age learners in a computing classroom.

    These two studies highlighted instances where PPs are more or less relevant depending on a student’s level of expertise or self-efficacy. In addition, the best PP to solve may differ from one student to another, and so having the same PP for all students to solve may be a limitation. This prompted the team to conduct their most recent study to ask how large language models (LLMs) can be leveraged to support students in code-writing practice without hindering their learning.

    Generating personalised PPs using AI tools

    This recent third study focused on the development of CodeTailor, a tool that uses LLMs to generate and evaluate code solutions before generating personalised PPs to scaffold students writing code. Students are encouraged to engage actively with solving problems as, unlike other AI-assisted coding tools that merely output a correct code correct solution, students must actively construct solutions using personalised PPs. The researchers were interested in whether CodeTailor could better support students to actively engage in code-writing.

    An example of the CodeTailor interface presenting adaptive Parson's Problems.

    In a study with 18 undergraduate students, they found that CodeTailor could generate correct solutions based on students’ incorrect code. The CodeTailor-generated solutions were more closely aligned with students’ incorrect code than common previous student solutions were. The researchers also found that most participants (88%) preferred CodeTailor to other AI-assisted coding tools when engaging with code-writing tasks. As the correct solution in CodeTailor is generated based on individual students’ existing strategy, this boosted students’ confidence in their current ideas and progress during their practice. However, some students still reported challenges around solution comprehension, potentially due to CodeTailor not providing sufficient explanation for the details in the individual code blocks of the solution to the PP. The researchers argue that text explanations could help students fully understand a program’s components, objectives, and structure. 

    In future studies, the team is keen to evaluate a design of CodeTailor that generates multiple levels of natural language explanations, i.e. provides personalised explanations accompanying the PPs. They also aim to investigate the use of LLM-based AI tools to generate a self-reflection question structure that students can fill in to extend their reasoning about the solution to the PP.

  • SPIN is a beautiful and imaginative AI synthesizer

    SPIN is a beautiful and imaginative AI synthesizer

    Reading Time: 2 minutes

    If you’re heard the pop music emanating from any recent reality TV show, you won’t be surprised to learn that AI is perfectly capable of generating tunes on demand. It won’t replace true artistry any time soon, but AI music fits all of the technical criteria. But typing a prompt is boring, which is why Arvind Sanjeev constructed this gorgeous and imaginative AI synthesizer called SPIN.

    SPIN is beautiful and looks like a cross between a turntable and a drum machine. Those visual cues hint at its function. The user can press buttons on the right-side pad to define musical characteristics, which then form a prompt for a language model called MusicGen. That synthesizes music according to the selected characteristics, like “happy” and “lo-fi.” The music then starts playing and the user can control its speed and direction using the record on the turntable — even scratching like a DJ if they want.

    A Raspberry Pi 4 Model B runs MusicGen, but it receives inputs through an Arduino Mega 2560 connected to the buttons. There are also dials to set song duration and BPM (beats per minute), as well as control knobs.

    The turntable is a Numark PT-01, but the vinyl is a special dummy record that only contains a time code track. The sound from that then feeds through the audio driver back to the Raspberry Pi, where it is decoded to control the playback of the synthesized music. 

    SPIN is truly stunning to look at and its functionality is quite interesting, but Sanjeev’s real motivation was to raise awareness about the ethics of AI-generated art and the original human-made art it is trained on.

  • Upgrade your shop with voice-controlled smart LED lighting

    Upgrade your shop with voice-controlled smart LED lighting

    Reading Time: 2 minutes

    Congratulations! You finally have a garage to call your own and you’re ready to turn it into the workshop of your dreams. But before you go on a shopping spree in Home Depot’s tools section, you may want to consider upgrading from that single dim lightbulb to more substantial lighting — otherwise, you’ll never find the screws you drop on the ground. LeMaster Tech can help with his great video on installing DIY voice-controlled smart LED lighting.

    LeMaster Tech’s primary goal was simply to increase the brightness in the garage. He took the route that gives the best bang for the buck: LED tubes. Those are similar in form factor to fluorescent light tubes, but they can put out more lumens with fewer watts and they tend to last a lot longer. They also don’t need expensive and bulky ballasts. LeMaster Tech installed several of those on the ceiling of his garage, then took things to the next level.

    These LED light tubes work with standard household mains AC power, so they can be wired like regular light bulbs. But instead, LeMaster Tech made them smart by wiring them through a relay board controlled by an Arduino UNO Rev3 board. That lets the Arduino safely switch each light tube on and off. LeMaster Tech gave it the ability to do that in response to voice commands by adding a DFRobot Gravity voice recognition module. That handy module works entirely offline and uses a simple AI to recognize spoken words. It has 121 built-in words and supports 17 custom words, so LeMaster Tech was able to tailor it to his needs.

    Now he can switch the lights with a simple voice command and even activate pre-programmed effects, like flashing the lights.

  • Build a better spindle controller for your CNC mill

    Build a better spindle controller for your CNC mill

    Reading Time: 2 minutes

    Proper spindle speed control is necessary to get good CNC milling results. If your spindle speed is inconsistent, your speed and feed calculations will be wrong. That will lead to poor finishes and even broken end mills (and ruined parts) in extreme cases. But cheap CNC mills and routers often have insufficient spindle speed controllers. That’s why Joekutz’s Workbench built an improved spindle speed controller for his generic CNC 3040.

    This DIY spindle speed controller has two major improvements: more precise adjustment and closed-loop feedback.

    The original controller just had an imprecise potentiometer knob and dot markings, making it impossible to set to a specific speed. The new version lets the user set the spindle to a desired speed with a digital readout.

    It also has closed-loop feedback, so it can adjust power to the motor as necessary to maintain the set speed under load. Without that, even a light load could slow down the spindle and throw off the speed/feed balance. 

    Joekutz’s Workbench achieved this using an Arduino UNO Rev3 board. It reads input from a rotary encoder to set the motor speed, then shows that speed on a seven-segment display. It controls the motor speed via PWM through a DIY optical isolator, a transistor, and a MOSFET. At the same time, it receives feedback on the real-world motor speed using an LED and photoresistor. That measures the reflectivity of the spinning spindle, which has a piece of aluminum foil tape in one area to increase reflectivity. That lets the Arduino detect a revolution of the motor and calculate the RPM. 

    [youtube https://www.youtube.com/watch?v=_ExjwMC0-Nw?feature=oembed&w=500&h=281]

    The CNC mill uses an Arduino Mega 2560 with GRBL for controlling the axes’ stepper motors. The Arduino Uno spindle controller can receive g-code speed commands from that, or the user can set the speed using the rotary encoder dial.

    HeroMasteryGauntlet.png

    Bringing a Whole New Balance to Gameplay

    Season 9: Champions also introduces global balance changes that affect every hero in the game. We’re adjusting how the damage dealt is more consistent by increasing the projectile size while also increasing the health pools of all heroes, thereby keeping the time it takes to eliminate targets relatively the same. We also added a new passive for all heroes to regenerate their health when they step out of combat.

    If you haven’t already, read up on the full details of these changes in our previous blog or check out our patch notes.

    Justice Rains From Above

    Season 9 also presents significant updates to Pharah, made with some strong goals in mind:

    • Empower Pharah to make more individual plays and lessen her reliance on heroes like Mercy.  
    • Shift Pharah’s movement capabilities from feathering up in the sky toward more horizontal movement that can cover distance quickly. 
    • Introduce brief moments of downtime for Pharah’s flight.

    These goals are aimed at enabling Pharah to be more effective at higher ranked thresholds and as a solo hero, while also addressing rougher experiences players have going against Pharah – such as her presence limiting the effective hero pool of the opposing team.

    PharahUpdate.png

    Pharah’s Hover Jets passive has been reworked to limit her time in the air, with fuel being recharged only while she is touching the ground. To compensate for this large change,  Pharah has more speed and acceleration while in the air, allowing her to traverse between areas quicker. Jump Jets also now provide bonus fuel (50% of the total tank) and that overflows if you hit 100% fuel. So, while there are moments of downtime introduced, Pharah players will have much more control of where they want to be on the battlefield during that time in air.

    Pharah also has a new ability called Jet Dash. When Pharah uses Secondary Fire she will dash in the direction she’s moving. When combined with Concussive Blast and the enhanced mobility from Hover Jets, Pharah can quickly navigate herself into positions where she’s highly lethal.

     This more active Pharah means a healthier game and offers new levels of skill expression. We’re looking forward to your feedback on these Pharah changes.

    Rolling into Junkertown

    And finally, a big update for the wild and rowdy Junkertown map is coming this season. The first section of the map (the area by the first checkpoint) is quite open. It can be tough for the offensive team to push the cart through here if the defending team has a Widow or Pharah. So, we’ve replaced the small cover with a trusty, burned-out building. We’ve also replaced the outhouse that was close to the gate with a tall water tower to block the line of sight from the openings above the choke point. Additionally, a few more cars have been added to this area, and the cliffside path has been reduced.

    Junkertown.png

    The small health pack on the balcony overlooking the hairpin turn on the second area has been removed to lessen the defender advantage from that choke. In the third area, we added a vertical support beam on the left side of the hallway to block the sightline from the upper ledge to give more cover for attackers to enter the area. We also widened and added cover to a hallway on the outer mid-section of area 3 to open up team fights that happen there. Finally, the updated map features a new night-time lighting theme to try out.


    Overwatch 2 – Season 9: Champions begins tomorrow, so answer the call and challenge yourself on the Competitive ranks today.
