The Digital Green Certificate (sometimes named green pass) is a digital certificate, common throughout Europe, which proofs that a person: is vaccinated against COVID-19 received a negative test result recovered from COVID-19 It’s normally issued as a qrcode, to speed up its reading by checking apps. On a technical level, the personal information of the…
Pi Zero is a small board – part of the Raspberry family – designed for embedded applications where space is a constraint. The low cost (about 10€ for version W, with wifi connectivity) and the ability to run different operating systems makes it the ideal choice for different applications (media centers, data loggers…). Raspberry Pi Zero unfortunately doesn’t offer a dedicated audio…
After having brought a Raspberry Pi Zero, I asked myself how to access it and do some initial configuration because of in that moment I hadn’t an HDMI monitor or an USB keyboard and a mouse. Fortunately, this Raspberry model supports USB OTG (On The Go): it can “become” a slave USB device such as a…
Exactly 4 years after the announce of the first Raspberry, today the Raspberry foundation unleashed the new Raspberry Pi 3: Its main features are: [checklist] a new CPU (Broadcom BCM2837, 1.2GHz 64-bit quad-core ARM Cortex-A53) WiFI (802.11n) and Bluetooth 4.1 onboard (at least! ;)) complete compatibility with the previous Raspberry 1 and 2 [/checklist] The new Raspberry is already available from…
If you read some of my latest projects (for example Home automation with Telegram BOT) you probably noticed that I really like the node.js javascript runtime. The framework is frequently updated (the moment I’m writing the latest version is 4.3.1) but if you use a Raspberry Pi running Raspbian you may have found that the official packages are quite outdated. For example, if…
The project I’m going to describe today it’s a sort of proof of concept that will demonstrate the possibility to remote control sensors and actuators (for example a couple of relays) via Telegram. Telegram is an instant messaging application, similar to the famous Whatsapp. Last June, the Telegram developers announced that a new set of APIs were available to…
I’m working on a project based on a Raspberry Pi, controlled by an external device (laptop, smartphone…) and therefore I was looking for the most universal way to connect the device to the Raspberry. Thanks to a small usb->wifi adapter you can transform the Raspberry in a wireless access point that broadcasts a wireless network your device…
The Raspberry Pi, thanks to the Videocore 4 GPU integrated in the Broadcom BCM2835 chip, is perfect for a home mediacenter; the GPU is indeed capable to decode full HD videos. In this tutorial I’m going to explain how to install and use Raspbmc.
OpenWrt is a famous Linux distribution for embedded devices. It was started as a replacement for the original firmware of routers and access points. On April 25, they announced the new version, named Attitude Adjustment (12.09), that adds the new brcm2708 target, that is the Broadcom chip used by Raspberry Pi:
Tony is working on small expansion boards for the famous Raspberry Pi. You can read about the development of those modules, called MiniPiio, on his blog: [checklist] Protoboard RS232 Full H bridge Relay … [/checklist] Tony wrote also a very good article on Instructables about how to create a breadboard adapter for Raspberry Pi.
