Custom machine stand ‘lets you know’ if drill bits aren’t stored properly

via Arduino Blog

YouTuber Cranktown City recently acquired a new milling machine/drill press, and needed somewhere sturdy to place it. Rather than buying something, he went to work making a nice custom stand with a drawer on top and space for a toolbox below that.

To help keep things organized, this top drawer features a 3D-printed drill index with an interesting trick. In addition to providing storage for the drill bits, it “encourages” you to put them back. Each drill cavity has a small switch, all of which are daisy-chained together. The switch signal is fed to an Arduino Nano, which reads high when all drills are present, and low if one or more is missing. If one is missing for too long, it triggers a sound module that insults him into proper organization, and lights up a strip of LEDs as an extra reminder.

Code and CAD for the project is available on GitHub if you’d like to try something similar!

Arduino World Gathering 2021: the official community conference you can’t miss

via Arduino Blog

We’re proud to announce the Arduino World Gathering, taking place everywhere in October 2021. Multiple days packed with workshops, lightning talks and project demos; a virtual event for everyone to enjoy.

This is a conference made by you. Whether you built a cool project with Arduino for fun or profit, you want to share a neat hack with the novice users, or you want to host a workshop a particular skill, technique, or special know-how you’ve acquired – we want you. 

Hackers, creators, designers, engineers, educators. Stop what you’re doing and start putting your ideas together now. A call for proposals will open soon.

We’ll talk about hardware, software, open source, creative technology, interactive art, smart products, professional applications, education, home automation, Internet of Things, artificial intelligence and more. All things Arduino!

Enter your email to get notified about the call for proposals and any other AWG updates:

Tune in to the official Arduino Day 2021 livestream

via Arduino Blog

The Official Arduino Day live stream will be hosted on the Arduino website and social media channels from 4pm CET on March 27th, 2021.

Arduino Day 2021 explores the idea of “undistancing,” with a packed roster of talks, demos, presentations, interviews and more that show us how Arduino can bring us together, even when we’re apart.

The schedule of the event will be posted in the next few hours on the Arduino Day page.

Remind-Ino is an alarm clock for everything

via Arduino Blog

Who says an alarm clock just has to beep, or annoy you in the mornings? Certainly not MakeUnited, who’s put together an Arduino Nano verbal reminder project over on Instructables. His device lets you program a whole bunch of alarms that each play a specific MP3 file.

The REMIND-INO is styled to look like a vintage radio, as the maker’s target audience is his grandparents. That being said I’m not a grandparent, and this would be an ideal way to substitute my inability to keep track of what time it is… ever.

There’s no limit to the reminders or alarms you might program into the REMIND-INO, but MakeUnited has a couple of suggestions:

  • Reminding people to perform tasks at specific times.
  • Tell stories, read books, teach cooking recipes and even play songs.
  • Keep track of appointments.
  • Anything else you might need a timely verbal prompt for.

And because it’s designed for an older demographic, he’s kept the controls super simple.

When an alarm goes off, it continues to repeat the message until you hit the big, illuminated button on top. Or after five minutes, just so it doesn’t become a major annoyance.

It’s an amusing project, as you can see from the build-along video. But it’s also easy to see how useful and practical it is. We see his grandparents being reminded to take pills, and to set off for an appointment. Alarms that anyone would find useful, regardless of age, and the verbal alert just makes it all the more effective.

The simplicity of the project would really keep the costs down too, and there’s loads of room for expansion and innovation if you wanted to build on this ingenious project.

In case you need it, here’s a reminder of where you can find the project on Instructables.

Join Us on the Official Arduino Day Live Stream on March 27th

via Arduino Blog

Everything’s in place and ready for the global celebration of Arduino’s sweet sixteenth birthday, including some amazing interviews, demos and talks. See you on March 27th at 4 p.m. CET on Arduino’s online channels.

It’s Arduino’s sweet sixteenth on March 27th, and after such a tough 2020 we wanted to make it an extra special event.

As you’ve probably already seen, we’ve themed this year’s Arduino Day around “Undistancing: open makes us close”, which is all about using everyone’s favorite tech to bring people together and find new ways to connect while we’re physically apart.

Presentations

There are so many topics the Arduino team wanted to cover this year that we’ve got lots of great presentations in the works for you.

Not least of them being a new inclusivity program called #include, that’s being integrated into Arduino as we speak, but there are big plans to bring it out into the community too. Isabela Freire from the Arduino Design Team will be with us to tell you all about that, and how it can benefit your projects, causes and communities.

We also want to show you around some of the top new Arduino devices, with some big reveals that are guaranteed to get people excited across the maker, education and professional sectors. The Nano RP2040 Connect is definitely going to be a highlight you won’t want to miss.

Interviews

Arduino Day is just as exciting to those of us inside the company, as well as you guys out there in the community. It’s at events like this where we get to talk to brilliant people who are making a genuine difference to the world through open-source tech.

Among them is the ever-inspiring Judi Girò Benet and Billy Chen, co-founders of the amazing breast cancer testing device The Blue Box. This incredible project recently won the international James Dyson Award, and it’s a remarkable tale of a first-time maker who brought her vision to life through Arduino and prototyping her own electronics.

We’ll also be revealing the 10 winners of this year’s Arduino Day Community Challenge. So if you’ve submitted a project to the competition make sure you’re online to find out if a treasure trove of Arduino gear is on its way to you.

Talks

Our very own Massimo Banzi is ready to give you a personal tour of the Tiny Machine Learning (TinyML) Kit. Together with Prof. Vijay Janapa Reddi of Harvard University – who specializes in mobile, cloud and edge-centric computing systems – they’ll discuss the impact that devices like TinyML can have in the education sector.

Ubi de Feo from Arduino Tooling Team will then follow with a first-hand demo of the exciting new Arduino IDE 2 beta, in which he’ll show us how this awesome platform represents the next evolution in accessible firmware development. Everything you ever wanted to know about the new IDE, plus a few new features in the pipeline.

Arduino Day Live Stream

So set the day aside on March 27th to join in with the Official Arduino Day live stream, which launches at 4:00 p.m. CET on the Arduino channels.

Get your seat on the front row at day.arduino.cc, and if you’ve any comments or questions in the meantime, just let us know. 

Oh, and if you want to see your face on the live stream, why not record a short video clip of yourself saying a big happy birthday to Arduino, and we’ll add you to the celebrations!

Just post it on social media with the hashtag #ArduinoD21 and we’ll stick a virtual candle in the sweet 16th birthday cake just for you!

Creating an over-engineered random number generator Arduino shield

via Arduino Blog

Often when working with Arduino projects, you’ll need to generate a random number. There’s a random() function built into the IDE that works acceptably in many cases, but maker_ATOM wanted to take things to the next level, creating an “over engineered true random value generator.”

This device sits on top of an Arduino Uno as a shield, and features input from a floating pin a seed value. It adds light input as a second seed value with an LDR, and ambient noise via a microphone as a third value. These are used to choose from an array of Pi digit values, which are also random, revealing outputs on its OLED display at the push of a button that would be exceedingly difficult to predict! 

More details on the project can be found in maker_ATOM’s Instructables post.
