Today’s project, as always based on the enc28j60 ethernet controller, allows to toggle relays (or, generally, digital PINs) using a responsive web page, that is a page that automatically adapts its layout to devices with different screen sizes (for example your smartphone and your PC). Video presentation Web site The web site, stored on an SD card and…
Today I was asked how it could be possible to resume a PC from standby at a given hour… It was enough to connect an Arduino Pro Micro to an RTC module, write some code and the WakeMeUP project was born…
Today I was virtualizing a Linux server using the latest version of the VMware’s vCenter Converter Standalone and I had a problem: the Helper VM, that is the virtual machine created by the Converter to be the target of the virtualization process, had no default gateway and thus it was unreachable from the other VLANs (including the one the server…
On IIS you can define custom error pages for the different HTTP error codes (for example the code 404 stands for “page not found”). Today I needed to revert the custom error pages to the default ones for a subsite: You can remove the custom configuration forcing the inheritance. Open the Configuration Editor: Choose system.webServer/httpErrors as Section, right-click…
If you updated the Arduino IDE to the latest version (1.6.3), you may have noticed a great improvement: a new tool for library management. In past indeed there was no a single place where you may found almost all the available libraries and the installation process was not so easy… with the new IDE instead if…
Here’s the last part of my videotutorial about building a quadcopter with less than 100 euros… today you’ll install the propellers, the legs, the battery and… you’re ready to fly! Please remember to enable the english subtitles… If you want to view all the videos, I published a playlist on Youtube that includes all of them…
Our quadcopter is nearly completed… in today’s videotutorial (remember to enable the english subtitles) you’ll learn how to complete the building of the frame and also how to tidy up a bit the wiring: The cables between the ESCs and the motors have been shortened, soldered and protected with some heat-shrink tubing: All the cables have been…
After having connected all the components of our quadcopter, it’s now time to configure the Flight Control Board connecting it to the PC. Before watching the videotutorial, you have to install the latest version of the OpenPilot software, available on the official site. The install process is very simple and well explained on the wiki. Here’s the videotutorial,…
It’s now the time to install the Flight Control Board (CC3D) and to connect it to the different components of the quadcopter… as usual here’s the videotutorial with english subtitles: I mounted the flight control board using four plastic spacers: very important is to install it with the arrow printed on the PCB that points…
Today I’m going to install the Power Distribution Board, that is the board that “distribute” the power from the battery to the different components (ESCs, LEDs…) of the quad. Here’s the videotutorial, if you can’t understand the italian language, remember to enable the english subtitles: The PDB is mounted on the frame using some plastic spacers:…
