The following tutorial will show how you can create a web dashboard to graphically display data using the standard vectorial format SVG. Introduction I was looking for a way to show in a graphic form data coming from a feed on Pachube: I needed to create a dashboard available via web and without proprietary technologies (Flash…). I found this blogpost by…
In this second post about my Nixie clock, I’m going to show you how to drive those tubes with a microcontroller.
Arduino team has just released the long-awaited version 1.0 of their IDE. Many new features, including a new extension for sketch files (.ino), new protocols (DHCP, DNS) for Ethernet library, a refreshed GUI… Here the annuncing post on the official blog with all the new features, while here you can download the new version. Let me know your first impressions!
The following project was designed for a need: with my friend Davide I’m working on a model railway (Il Plastico di Davide e Luca): we needed to know how much current it uses to size our power supplies (booster)… The sensor For current measurement, I used ACS712 sensor from Allegro MicroSystems (here’s its datasheet). You can find…
A project I’m working on is a Nixie clock… in these posts I’m going to show its development!
For some time, I’m interesting in the different ways to build home-made 3d printers.
A reason probably reduced the use of the 32 bit family of Microchip’s PIC microcontrollers in hobbistic projects is that those microcontrollers were available only in packages hardly hand-solderable. Starting from November, are now available the first PIC32 in DIP package, at the moment I’m writing: PIC32MX110F016B PIC32MX210F016B PIC32MX120F032B PIC32MX220F032B All in a 28pin package. The main differences between the…
Sometimes you need to use a device – found in a project downloaded from Internet – in one of your projects; here’s how to do it in Eagle:
OpenHardware, an organization that exists to support, assist, and promote the idea of open hardware has just made available the first issue of its online magazine: even if its layout is quite “home-made”, the magazine is full of interesting topics! http://openhardware.org/journal/
ArduRGB it’s a simple project to show how to drive an RGB led with Arduino. In the GitHub repository you can find the Arduino sketch and a sample program written in C# and in the forum you can ask for informations,requests… [highlight color=”yellow”]Warning: the program described below is designed for a common cathod led, if you need to use…
