MIDI Drum Controller “Atomic”

Hi! This is ATOMIC, a 6-pad MIDI drum controller made with Arduino made for music production and fun!

The button allows you to change the notes of the pads which is defined in the codes as modes A (Pattern) and B (Fill mode). The idea behind this is that you first record the basic pattern in you DAW and then you add extra sounds like toms or plates. Two LEDs indicates which mode are you using, and there´s a connection for a hi-hat pedal.

Speak4Me is an eye-to-speech module designed to assist those unable to communicate verbally

People who suffer from physical disabilities that leave them unable to speak or communicate effectively can end up frustrated or largely ignored. In response to this issue, Hackaday users MalteMarco, and Tim R wanted to create a small device that can turn small eye movements into simple commands and phrases for easier communication, which they call the “Speak4Me.”

At the most basic level, the Speak4Me consists of an Arduino Nano board that controls a set of four infrared sensors which are pointed at the user’s eye within a single glass lens. Then once every 100 milliseconds, a measurement is taken to determine the location of the pupil and thus the direction being focused on. The word or phrase is chosen by first selecting a profile containing four groups of four elements each, for a total of sixteen possible combinations per profile. As an example, the caretaker profile has elements such as “yes,” “I want to sit,” and even “I need medical treatment.”

Arduino Sinewave Generator

A signal generator usually has various signals that is can generate, such as Sine, Square and triangle. Others have a sweep function and an arbitrary waveform. These are useful tools in the workshop. They can be used to test out audio circuits, op amp circuits and testing circuit response. Most modern function generators can easily put out frequencies up to 1 Mhz.

So, while I did not expect an Arduino based sine wave generator to replace my desktop function generator, I thought it would be interesting to see how to go about designing one and how it would perform.

How To Make Robots Move Smoothly | Arduino Tutorial

There are lots of great animatronic and robotics props and projects out there, and it’s easy to make r/c servos and other actuators move using the Arduino servo library. This means that the servos stops and start very suddenly, moving as fast as they can between positions. In this video I’m going to show you two lines of very simple code to make things smoother.

Sensitive Arduino Lightning Detector with Homemade Sensor

How to make a sensitive homemade lightning detector based on cheap AM receiver IC TA7642 and Arduino Nano.

A lightning detector is a device that detects lightning produced by thunderstorms.
In one of my previous videos, I showed you how to make such a detector with the help of the AS3935 sensor board which is specially designed for this purpose. This time I will show you how to make same such device, but now with a homemade detector circuit based on cheap AM Receiver IC TA7642.

The new Arduino CLI 0.19.0 is out and better than ever!

There’s a truckload of news from the Arduino Tooling Team today: Arduino CLI 0.19.0 is now available! This release has tons of great enhancements, exciting new features and heaps of bug fixes. Some things required quite a bit of breaking changes but they’re worth the hassle.

The highlights of this release are certainly the addition of pluggable discovery and the internal restructuring of the startup steps of the Arduino CLI. These affected the JSON output of some commands and the gRPC interface functions, which is documented in the upgrading guide.

Sparkpad Sparks Joy for Streamers

The best streamers keep their audience constantly engaged. They might be making quips and doing the funny voices that everyone expects them to do, but they’re also busy reading chat messages aloud and responding, managing different scenes and transitions, and so on. Many streamers use a type of macro keyboard called a stream deck to greatly improve the experience of juggling all those broadcasting balls.

Sure, there are dedicated commercial versions, but they’re kind of expensive. And what’s the fun in that, anyway? A stream deck is a great candidate for DIY because you can highly personalize the one you make yourself. Give it clicky switches, if that’s what your ears and fingers want. Or don’t. It’s your macro keyboard, after all.

DIY Reflow Plate

I’m preparing a video where I show you how to make the PCB design and order the panel version for your board and then solder all components at once. In that way you can save time and finish your product faster so they will be ready for sale. To do that I need a reflow hot plate and that’s what we will build today using a second-hand clothes iron. We need to measure the temperature, show the power and that temperature on a screen so the user could see the values, we need to control power and in this case a lot of power because my iron is of 3000W, and then we need to have some sort of menu or control in order to select the settings. Let me show you what parts we need, the connections I will do, how to measure and control the temperature at high power and also show you the code. Finally, let’s see if this homemade reflow hot plate will work and if I can reach the desired temperature curve, so what do you think, will it work? So, guys, let’s get started.
