A High altitude balloon sensing the earth’s atmosphere

Wednesday, September 9th, 2015


The project Emanuel Bombasaro submitted to the Arduino blog is about a high altitude balloon he launched on August 21st over Denmark. The balloon, called Titan 1, is made of a helium-filled latex balloon,  a payload box holding the flight computer, sensors and a parachute (36” diameter). A GoPRO camcorder mounted inside the payload box and capturing an image every second.


The flight computer is an Arduino Mega which logs position (GPS), pressure, temperature, humidity, luminosity, earth magnetic field, acceleration and spin, measured by a variety of sensors:


A DIY smartwatch designed by a kid for kids

Tuesday, September 8th, 2015


Omkar is a special 8 years old who created a wearable device called O Watch: an Arduino Zero-based smartwatch kit for kids. The project, recently kickstarted, allows young people to learn programming, 3D printing and a bit of craft while making their own smartwatch and customizing it. The kit will be released with a series of learning tools including a kid-friendly website with easy tutorials, examples and a community to share creations. (more…)

A JTAG/XSVF Library for Arduino

Wednesday, September 2nd, 2015


Marcelo Jimenez developed a library to use an Arduino as a JTAG programmer. Basically a Python script uploads a XSVF file to an Arduino which interprets it and performs the necessary JTAG manipulation in order to do the programming.

The project is pretty simple because it just uses  a few resistors and some wires and the library is included in the Arduino library manager or you can check it  on Github.

He also wrote an article to explain some JTAG, SVF and XSVF basics: (more…)

Play like a spy with L.E.A.P. Engine

Wednesday, August 26th, 2015



Toronto-based collaborative duo Hopkins Duffield created a gaming environment running on Arduino Mega in which the player battles a laser wielding A.I. security system gone awry. It’s like being in an action movie, walking in a pitch black room filled with the hollow sound of a machine breathing and a series of red laser fences slicing through the fog-filled air!

Originally from Guatemala, Balam Soto is an artist and maker of software and hardware creating interactive art installations and public artworks that fuse low tech with high tech. He recently shared with us a project called Exp.Inst.Rain and running on Arduino Uno: (more…)

A tribute to 5-bit Baudot code

Thursday, August 20th, 2015


Julian Hespenheide is an interaction designer based in Germany who submitted to Arduino blogpost a writing machine called émile. It’s an interactive installation created in collaboration with Irena Kukric, David Beermann, Jasna Dimitrovskais and using Baudot code - a binary 5-bit code, predecessor of ASCII and EBCDID – intended for telecommunication and electronic devices, representing the entire alphabet.

Preparing 200 teachers to inspire students with electronics

Thursday, August 13th, 2015


Arduino Verkstad has just started CTC* Catalunya 2015 in Barcelona with David Cuartielles preparing a group of 200 teachers that will be teaching CTC to students in Cataluña next September. A technology fair will be hosted at the end of the program and we are expecting more than 2500 people to attend.

Creative Technologies in the Classroom (CTC) is a collaborative learning curriculum designed for schools that wish to incorporate emerging technologies into their existing technology classes. It’s also a collection of experiments aimed at transforming the way technology is taught in schools around the world. These experiments introduce basic concepts in programming, electronics, and mechanics.These experiments introduce basic concepts in programming, electronics, and mechanics. (more…)

A DIY Seizure Alarm based on Arduino Micro

Tuesday, August 11th, 2015


Chad Herbert’s son Daniel was diagnosed with Benign Rolandic Epilepsy in 2014. It’s a type of epilepsy the Epilepsy Foundation says accounts for about 15 percent of all Epilepsies in children and the good news is that most children grow out of it.

The bad news is that Daniel’s most affected by his condition at night or early morning while he sleeps. That’s why Chad invested in a sleep monitor/alarm for his bed that detects when he’s having a full tonic-clonic seizure. (more…)

A traditional weather house gets a smart upgrade

Friday, August 7th, 2015


The “Enchanted Cottage” is a project by Andy Clark with the aim of upgrading a traditional  german “wetter haus”  with a new mechanism and electronics running on Arduino Yún:

The mechanics were replaced with a servo and 3D printed parts designed to make the movement linear rather than arcing as in the traditional approach. The figures were fitted with magnets so that they could move without any obvious form of propulsion.
The electronics were based on an Arduino Yún, custom prototyping shield and an Infineon RGB LED driver shield. The whole thing is powered by a rechargable LiPo battery and a module from AdaFruit. Because the Arduino was deep in the middle of the house, I used fibre optics to bring the light to the top panel. A sensor was added into the roof so you could simply tap it to get it to update the forecast for you.

The project was build over a period of 16 weeks, the mechanical aspects were completed first and the 3D printing took several goes to get it right. The electronics build was fairly straightforward but fitting everything onto the proto shield was challenging and the high clearance for the Yún was also a challenge. The software was written as I went along with demo programs created to test each part. Getting the Yún to work on low power was fairly straightforward but getting a secure and validated HTTPS connection took a few attempts. tried to put as much of the processing into the Python script so that the C++ code was just handling the control. All in all a challenging project that pushed the Yún to it’s limits.


Build an IoT Gauge with Arduino Yún and IFTTT

Wednesday, August 5th, 2015


Tomas Amberg shared with us the link to an Instructable he published on how to build a Web-enabled, Arduino-based IoT Gauge with a REST API, and connect it to the IFTTT mash-up platform, via the relay service he founded.

The cool thing about this project is the connection with the Maker Channel  of IFTTT which supports custom Webhooks, to integrate DIY IoT projects:  (more…)
