Arduino-controlled blinds: a tutorial

Friday, October 5th, 2012

Have you ever wanted a smart home that can automatically adjusts the blinds for you? If so, this project is for you.

In this instructable, the author describes his approach to “smart blinds”, by using an Arduino board, an ethernet shield, a motor shield and a couple of sensors.

By means of a simple web-based GUI, the user can manually open and close the blinds, or he/she can setup both temperature and brightness thresholds in order to automate the whole process. Finally, opening and closing events can also be scheduled at pre-defined times of the day, if necessary.

The complete tutorial, together with the source code of the project, can be found here.

Space experiments for everyone: the ArduSat project

Tuesday, June 19th, 2012

ArduSat, which stands for “Arduino satellite”, is a recently kickstarted project that aims at developing an open platform usable to emulate space scientists:

Once launched, the ArduSat will be the first open platform allowing the general public to design and run their own space-based applications, games and experiments, steer the onboard cameras to take pictures on-demand, and even broadcast personalized messages back to Earth.

ArduSat will be equipped with several sensors (such as cameras, gyros, accelerometers, GPS and more) packed inside a small cube (the side will be approximately 10 cm long) that can be accessed through a set of Arduinos.

Once in orbit, the ArduSat will be accessible from the ground to flash the required firmware for the experiments and for getting back all the collected information. People interested in performing space experiments will have access to a ground replica of ArduSat explotable to test and debug their code before the actual deployment.

The project is very ambitious, and it is expected that such an open accessible space platform will have a considerable impact on how simple space experiments will be carried out in the forthcoming years, in the case of fundraising success.

You may find the Kickstarter page of the project here.

Inexpensive 6-channels temperature scanner

Arduino powered temperature scanner with LCD screen display

Did you ever look for a cheap temperature monitor capable of collecting up to six sensor readings?

Johnathan Hottell needed to monitor the engine temperature of his LB7 Duramax diesel truck to avoid over-heating problems in hot days. Looking for commercial products, he found several quite expensive scanners (around hundreds of dollars), so he decided to build its own monitor using an Arduino Pro Mini, six NTC thermistors and a Nokia 3310 LCD screen to display the temperature readings.

The result, which is described here in great details, cost around 40 $.

Cheap Arduino-based Thermal Flashlight

Wednesday, May 9th, 2012

Thermal flashlight is a widely used technique to “paint temperature with light”: by using a temperature sensor and a RGB flashlight, it is possible to illuminate a surface with a proper tonality, which, in turn, can be acquired by means of a standard camera. It’s main use is to find thermal leaks in houses and buildings.

In their article, PLOTS‘ staff propose and describe a nice and cheap way to build your own thermal flashlight with Arduino, together with a clear introduction to the subject.

Cheap Thermocam Around 100$

Monday, March 14th, 2011

[Max] forwarded me an impressive project about a DIY Themal Camera. The overall cost for building it is around 104$, compairing to professional products ranging from from 2000$ to 30.000$.

after some time of research I want to present my latest project called “Cheap-Thermocam”. It enables to create thermal images of houses, electrical devices or other things. An infrared sensor is mounted on two servos for moving it up/down – left/right. For an optical image of the scanned area, a webcam is installed under the sensor. An easy to install computer software written in JAVA shows a preview of the webcam image and then collects all the temperature data neccessarry to create the thermal image. To do this, 1344 single points are measured in about 2 minutes, this is a rare resolution of 42×32 Pixels. The advantage of my project compared to commercial thermal cameras is obviously the price. Another positive aspect is that the pictures can be analysed and edited with my easy to use pc software. The whole project can be built in 2-3 hours without any difficult parts do be soldered.
