When we activated the HTTPS to secure the connection, users with Internet Explorer 8 were no longer able to display those PDF files: Adobe Reader was correctly started but the browser‘s window…
Starting with this post, you’ll find on my website a tutorial about the new Arduino Yun: I’m going to blog about my experiments with that board and show its features through real examples… today you’ll learn how to connect it to your wifi network!
Today I noticed I made a little mistake during the building of my 3d printer: the plastic holders for the rods of the y axis were mounted rotated 180 degrees and therefore the printing plate was too low: The proper installation is as follows: Now the endstop for the y axis also works fine:
Ultra Librarian is a tool by Accelerated Designs to manage libraries of eletronic components (CAD design, simulation, 3d-modelling…). Many IC manufacturers provide Ultra Librarian files (.bxl) for their products: this tutorial will show how to use those files in Eagle…
Led strips have become very common for various uses: from interior and exterior lighting, to decoration… today I’ll explain you which types of strips are available and I’ll show a pratical example for controlling them using Arduino and C#.
Yesterday at work I needed to write a script to check if an SSL certificate was present in the user’s store and – if not – to automatically import it…
I’m happy to share the following offer from Packt Publishing: until next monday all the eBooks (including my book 😉 ) are 50% off…
This small tutorial will explain how to build a circuit for optocoupling Arduino input PINs…
My friend Mauro, returning from the Maker Faire Rome, brought me an Arduino Yùn, the new board by Arduino that has – in addition to an Arduino Leonardo – a system-on-chip running a Linux distribution. Here’s a video about its unboxing: I was really surprised by the dimension of this new board: the guys at Arduino were…
I’m developing an application that will use custom fonts: you can avoid installing the fonts to the user’s PC embedding them in your app and loading at runtime: this tutorial explains how to do it…
