Laptop control box provides speedy access to apps

Wednesday, March 1st, 2017

If you need to quickly launch certain apps on your MacBook Pro, Carl Gordon has your solution using an Arduino Nano.

Although the TV ads for your notebook computer would perhaps have you believe that everyone who uses it is a DJ, artist, or rock climber, chances are you just use it for a handful of programs and folders over and over. If this sounds like you, you can at least speed up access to them using Gordon’s “Laptop Control Box.”

As seen below, the box acts as a grid of shortcuts to your favorite applications, with a button to select sets of programs and an embedded RGB LED module to show you which set is active without having to look at the screen. Control on the computer side is accomplished with Processing, and though it might look like its window needs to be active in the video, it can work in the background as well. (more…)

Remotely control a sumo bot with a gaming wheel

Tuesday, February 28th, 2017

Using an Arduino Uno, Nano, and two Bluetooth modules, engineering student “Roboro” can now remotely control his sumo robot.

Like many hackers, Roboro had an old gaming controller that he wasn’t using, in this case an Xbox steering wheel and pedals. Naturally, he converted it into a controller for his sumo robot, which can now be driven manually. This involved wiring the wheel controls into an Uno; the smaller Nano was used onboard the bot.

Rewiring a controller is nothing new, but what is also quite interesting from a hack point of view is that the Arduinos communicate over Bluetooth. When initiated, the controller connects itself to the robot, which can then be driven around (as long as it doesn’t get stuck in the hardwood). (more…)

Log high-altitude balloon data with this Arduino device

Monday, February 27th, 2017

Wanting to see data from their high school’s HAB launch, 9th grader “Spaceshark” and a few of his classmates decided to build their own data tracker.

According to the project’s write-up, Spaceshark’s school has an astronomy club which sends HABs to the edge of space. Although the 360-degree video embedded here would be enough to satisfy most people’s curiosity, this team wanted more data!

Spaceshark’s group proceeded to create a data logger using an Arduino Uno, along with sensors to collect data on the satellite’s latitude and longitude coordinates. Altitude, wind speeds, time, and the satellites in view can also be recorded, saving readings on a microSD card for later analysis. (more…)

Arduino Day Turin: Call for projects and volunteers!

Monday, February 27th, 2017

ArduinoDay2017_MainBanner

As recently announced, Arduino Day 2017 will be celebrated on April 1st. (If you want to organize an event of your own, please submit your proposal by March 11th.) Though festivities will be taking place worldwide, the Arduino team will be holding this year’s official event at Toolbox Coworking in Turin–which happens to be in the same building as Arduino’s new Italian headquarters.

The Arduino Day Turin program (11am – 6pm), organized in collaboration with Fablab Torino, will include an exhibition area with boards and projects, a talk area with speeches by Massimo Banzi and other Arduino co-founders, a workshop/demo area with free activities for kids–with the Fablab for Kids team–and adults, as well as an Arduino store with special prices and offers.

We are currently seeking projects for Arduino Day Turin’s exhibition space: if you are an individual or team of Makers and would like to show off  your creations, feel free to fill out this form by March 18th. If you are an Arduino enthusiast and want to help out, we are also looking for volunteers (application here) to welcome guests, document the event, and assist the Arduino crew.

Over the next few weeks, we’ll be sharing more news and updates on Arduino Day Turin’s agenda and activities. In the meantime, don’t forget to post and invite your friends via ia social media using the hashtag #ArduinoD17! 

A toast-buttering robot for your breakfast routine

Friday, February 24th, 2017

Tired of buttering your toast in the morning? Well, William Osman has just the solution for you, albeit slightly dangerous and excessive for the task at hand.

For his “extremely violent” machine, Osman used a jigsaw motor to hold the butter and an Arduino-driven linear stepper motor to move the slice of toast back and forth. The robot’s frame, spikes, and mounts are all crafted out of laser-cut wood, and everything is held together by a bunch of zip ties.

Power a 1980s MicroVox with an Arduino Uno

Thursday, February 23rd, 2017

After digging through an extremely complete manual, Monta Elkins used an Arduino Uno to make a MicroVox speech synthesizer do his bidding.

The bad thing about obsolete gear is that it is generally very hard to hook up to modern equipment. The great thing for Makers, though, is that many of the devices from one’s childhood (or before) can now be driven with inexpensive tools such as Arduinos. Some of them, like the 1982-vintage MicroVox model that Elkins got his hands on, even include a manual with schematics and components listed.

After going over his new find and the enclosed manual, the video really hits a highlight around 13:45, when he powers it on to hear it burp out “ready” in a deep monotonous tone that may bring back memories of the robotic future you remember fondly. He finally hooks up the Uno just after that, and gets it to spit out an “interesting” catch phrase just after 16:30. (more…)

Turn an old mixer into a MIDI input fader with Arduino

Tuesday, February 21st, 2017

Using an Arduino as an HID, Evan Kale turned a “gently used” analog mixer into a computer interface.

Older audio equipment may not have the interfaces that you need to make totally electronic music, but they can be very well-built, so are perhaps worth salvaging. In the video below, Kale salvages potentiometers from an old mixer, then hooks them up to a Pro Micro. This allows the Arduino to take these 12 inputs, and output them as a USB MIDI signal.

Along the way, Kale points out a few very important hacking tricks, including that the library may have a printer ready for you to use, and that analog slider pots many times are logarithmic (or close to it) and need to be calibrated. Also, around 5:25 he introduces viewers to analog multiplexers which can give you eight analog inputs at the cost of three digital and one analog pin. (more…)

M2 by Macchina joins AtHeart!

Tuesday, February 21st, 2017

M2 by Macchina

We’re excited to announce the latest member of Arduino’s AtHeart program, MacchinaNow live on Kickstarter, M2 is an open-source, versatile development platform for hacking and customizing cars.

M2’s two-part design is compact, modular, wirelessly connectable, and based on the popular Arduino Due. It consists of a processor board with a SAM3X8E Cortex-M3 MCU, a USB port, some LEDs, an SD card slot, and built-in EEPROM, as well as an interface board with two channels of CAN, two channels of LIN/K-LINE, a J1850 VPW/PWM, and even a single-wire (GMLAN) interface.

The tiny device (56.4mm x 40.6mm x 15.7mm) can be wired under the hood for a more permanent installation or plugged into the OBD2 port, enabling you to do virtually anything with your vehicle’s software.

 

Macchina has partnered with Arduino, Digi and Digi-Key to develop M2, and believes that its highly-adaptable hardware will most benefit hot rodders, mechanics, students, security researchers, and entrepreneurs by providing them access to the inner workings of their rides.

M2 accommodates a wide variety of wireless options thanks to its Digi XBee form-factor socket, enabling you to easily connect your car to the Internet, smartphone, satellites, or the cloud using BLE, WiFi, GSM, LTE, and other modules.

The platform can be programmed using the latest Arduino IDE, and is compatible with a number of software packages. Moreover, given its open-source nature, potential applications are bounded only by the collective imagination of the coding community. (more…)

Make sure guests never miss your house with these numbers

Monday, February 20th, 2017

If you’d like for someone to visit you, it’s quite helpful if you have the house number displayed somewhere on your premises. Rather than simply rely upon someone reading the numbers as they drove by, “Superbender” has decided to do something a bit different make his home stand out.

During the day, you can identify Superbender’s residence by the giraffe mailbox, but to help point the house out by night, he came up with the glowing Arduino Uno solution seen in the video here.

The numbers were cut on a scroll saw and RGB LED strips were added in the back to enable them to illuminate. The setup allows for one color per night, or the numbers can change every three seconds in “party mode.” (more…)

Bring some zen to your living room with this CNC end table

Friday, February 17th, 2017

Why settle for a some boring furniture, when you can have your own sand and rock display powered by an Arduino Uno and stepper motors instead?!

According to his write-up, Instructables user “MakrToolbox” gets many ideas that never leave the pages of his Moleskin notebook. Although it has to be difficult to decide which ones gets to live in reality, this Zen Garden CNC End Table seems like it was a great build choice.

The table consists of a piece of plate glass covering a “garden” of sand and stones. On top of this is a metal ball that moves around via a joystick on the side of the table, traversing the sand and making interesting shapes, like a giant Etch A Sketch. The ball is pulled around with a magnetic servo-powered gantry system underneath.

Look like something you’d love to have in your living room? Be sure to check out the project’s page for more! (more…)
