Loccioni Group, is an italian company that sponsors every year a project internship entitled “Classe Virtuale”, dedicated to young students coming from local technical schools.
This year, “Classe Virtuale 2012″ has been composed by 27 students with different backgrounds, selected among 120 candidates. After a stating training period, during the three-weeks internship the team worked on a very nice Arduino-based project: Flow Meter.
Here you may find a brief interview we had with Daniele Caschera, one of the components of “Classe Virtuale 2012″, about Flow Meter and on how Arduino helped in its design.
Ever wanted to see how much electricity your next project is consuming? Look no further; this Instructable will guide you about how you can, too, make a device to monitor the same.
“There’s a couple of commercial products that can do this, but not with the flexibility I wanted. I designed an Arduino micro-controller based solution that is very extensible. Right now it monitors the above values of attached gear, and I’m thinking about adding web monitoring and an SD Card for data collection.”
A beautiful project by [Leigh Davis]. It is a brilliant proof of how Arduino fits into virtually any sphere of thought and is the shortest path for a creator realizing his idea in reality.
He writes:
I began the first few days by developing a stand alone application build in MaxMSP that understands the notes that a play on my (recently purchased second-hand) flute. I set the range from low C right up to the 3rd octave D. Each note of the chromatic scale triggers a bang, which is coloured uniquely to the other notes bang messages.
The bang message then sets the corresponding color to the display screen on the application. Which will in turn send a signal to the arduino to dispense the corresponding oil color on water according to the different notes. (Something like a physical Milkdrop!)He further plans to control different LEDs, motors and the likes using the Rayne application.
Hypnotic installation from David Bowen representing *real* waves.
[...] Tele-Present Water installation draws information from the intensity and movement of the water in a remote location. Wave data is collected in real-time from National Oceanic and Atmospheric Administration (NOAA) data buoy station 46075 Shumagin Islands Alaska. The wave intensity and frequency is scaled and transferred to the mechanical grid structure resulting in a simulation of the physical effects caused by the movement of water from this distant location. The installation uses MAX/MSP to drive an Arduino mega running servo firmata. It uses 11 x 24volt dc motors with drivers for the movement.
[...]the newest member of the RobOrchestra. This amazing musician was built by club members with a total budget of $1000. The Vibratron uses an Arduino Mega to control 30 individual solenoid gates which drop steel balls onto the vibration keys. Using the Arduino Mega they were able to avoid complications with multiplexing I/O lines. Notes are read in using a MIDI shield to receive standard MIDI signals from a sequencer or keyboard. The balls are recirculated using an Archimedes screw to raise them to the bucket at the top.
[pabloxid] shared an Hexapod project on the forum based on an Arduino MEGA 1280 and 18 Dynamixel AX-12 motors:
SAMSA is based on the Wiring board, with an ATmega128 microcontroller, and SAMSA II on the Arduino Mega, with an ATmega1280. Both are pretty similar, tough the ATmega1280 has 8 KB SRAM, twice the ATmega128. For SAMSA II the Arduino IDE was not used. The software was written directly in C++, using some libraries from both Arduino and Wiring.
SAMSA II has also two additional microcontrollers. One is an old Arduino Mini (ATmega168) located in the head, tasked with handling the sensors. The other is an ATmega8 and is integrated in the display. The firmware in the display was replaced with another one, freeing the main microcontroller from handling the display pixel by pixel, storing the frame buffer, etc.
The head’s microcontroller is responsible for sampling, filtering and processing sensor’s data. The data from the Sharp distance sensor and the lateral IR sensors are combined in a single “super smart distance sensor”. This microcontroller also decodes the data coming from the 38 KHz IR receiver, used for the Remote Control.
These two additional microcontrollers further reduce the load on the main microcontroller, allowing for more sophisticated behaviours.
Bruno and Jonas, inventors in a cool DIY program on SVT Swedish television called “Mekatronik” made a nice super hero costume using (among other tools) an Arduino Mega. It’s in Swedish but still you can enjoy the building process if you don’t know the language.
Amazing Accordion sending MIDI under 100$ (instead of 6,699.00$), as [Dmitry Yegorenkov] shares on Arduino Forum and published on GitHub.
I like to play accordion & have a dog. People say dogs are singing with squeezeboxes and some people find it funny. Not for me. I know that my pet hears note harmonics much better then me & suffers from high pitches very much. I could not really practice at home just because of humanennes. That sucks. I like to play accordion. Programmers see cycle here. Let’s get out.
THIS IS IT. It plays to headphones, produces MIDI output, etc. etc. It costs $6,699.00 on e-bay (buy now offer) on November 17, 2010. In the US I can buy Peugeot Partner for the same price. In Ukraine where i live both are 1/2 times more expensive. For that money i’ll get beautiful device to practice at home and no service centers available within 400Km radius. Weird.
Squirtis an autonomous robot which can communicate with an Android phone. Optionally, the phone can be used as a controller to drive the robot. Squirt’s purpose is to water plants and chase away raccoons. It’s also a technology demonstration to prove the feasibility of using a smart phone to control small irrigation and well systems.
