Ultimaker 2 is among us! I’ve been waiting a long time to get one of those. After a research on internet this one seemed the way to go. And it hasn’t let me down. Continue reading to find out my process of getting a second hand Ultimaker 2 up and running (not easy). Continue Reading →
In this part we get our hands dirty by installing the sensor and putting the code in the arduino energy meter. Our “Hello world’ of energy metering.

For those interested, Arduino MKR1000 is a new board that Arduino is launching the next February 2016. It’s focus it in the IoT realm. Arduino and Microsoft have joined forces and initiate a contest which the 1000 first pre-selected candidates will win a brand new Arduino MKR1000 board before they are even released to the public.

Usually I do constant research on projects to automatize things at home, like energy monitor. Long time ago I came across this little nice post, explaining in a very simple way how to monitor your home energy consumption. On top of that he is using an ethernet shield that outputs the information through a MQTT feed to xively.com where it is processed and transformed in a nice bar graph.
UPDATE: Xively is not free anymore so this example will not work. Soon I will post an alternative using other types of logging.
UPDATE2: Here you can check another project using sparkun server and thingspeak server
There are lots of information on how can we drive WS2811 strips on internet but almost none about how to receive Artnet and drive WS2811 led strips at the same time. Here I try to explain how to get Artnet to WS2811 and the starting point on how to build one yourself.
Some of the Showtec Phantom fixtures started to have problems with the displays, so I decided to make this post for people experiencing the same problem.
Very recently I’ve been servicing quite a lot of showtec phantom 50 LED spot fixtures and after a couple of months I can say that I know them quite well. I tough it would be interesting to do a short review from a technical point of view of the Showtec Phantom 50 LED spots so that people interested can have a better insight of the inner design and common problems that might encounter if they decide to work with them.

I just found a set of posts explaining how to code a line following robot with a PID integrated algorithm. PID stands for Proportional-Integral-Derivative and it’s very useful for controlling many actions where a great level of control an prevision have to be achieved.
Here the set of posts by syclops. Great job!
