In the past 20 years I worked on a huge set of projects.
Here the one I think are useful
After some years in IoT, I tried a bunch of different platform like esp8266 but Arduino remains a must. Simple reason to choose it for your first (or second :) IoT project: Arduino works at 5V and can accept as input voltage 7-12V, but with limit up to 20V (avoid it! :).This mean you can …
UPDATED and BUGFIXED! MicroPython Repl command line is very nice, because you can telnet to the chip and read-and-evaluate python code. It is a great way of learning embedded IoT. The bad thing you cannot copy file while it is running, so experimenting get bad. Also an automatic module update would be a very nice thing to …
Qualche mese fa avevo sviluppato una applicazione IoT per misurare la temperatura e spedire i dati ad una coda mqtt. Poi c’era uns server che colelzzionava i dati. Totale: tre server, con tre punti di fallimento ma architettura molto “cool” In effetti però la potenza dei moderni chip embedded è tale che è possibile implementare …
After months of esp8266 experimentation, I “just” discovered this little chip has also a I2S Audio digital interface. To discover it you must install the Arduino IDE adapter and code directly in C++ (brr, ok not a breeze but not boring like Java :) I2S is a digital protocol to send your digital music to …
Arduino is a great hardware for a lot of reason: easy to use, difficulto to break, it is a very solid 5-Volt board. But it a way too much and it has a very limited amount of RAM. So I started exploring other more “different” solutions. I need an economy chip with some RAM …
A new version of an Arduino Realtime OS is on the go: Arduino AVR ChibiOS/Nil Library https://github.com/greiman/ChNil 4 forks. 15 stars. 5 open issues. Recent commits: Update to ChibiOS 17.6.0, Bill Greiman Fix include case error, Bill Greiman Initial commit, Bill Greiman :confetti_ball: Added .gitattributes & .gitignore files, Bill Greiman I have used with profit …
Beauty (OrgMode Parser 0.1.3) is here to stay! OrgMode parser is a small nodeJS library to parse Emacs OrgMode files (more info at this link). This version features: Fixed empty header issue Code Cleanup Migration from jade to pug2 (new name of jade) Added optional logging framework (winston) Also I’d like to thank all the …
After a lot of time, I am very happy and excited to announce a new release of org mode parser! I thank a lot the contributors. In short, we have a stronger parser and a new html rendering based on jade template engine. Also code blocks Support for source block enclosed in #+begin_src / #+end_src …
The BBC Micro bit an ARM-based embedded system designed by the BBC for use in computer education in the UK. The device has been given away free […] [to every 11 years old pupil] in the UK, and is also available for purchase by anyone. This is the wikipedia definition. With a 5×5 led matrix, …
Hi all, I have released version 0.1.1 of org-mode-parser for nodejs Org mode parser is a parser for reading Emacs org-mode files in nodejs. This version has been ported to VisualStudio Community Edition 2015, so you can develop easily under windows too (but only if you really want :)
After my two children grow a little, I have some spare time to play with RaspberryPi. I have bought a Raspberry Pi 2 Model B, a very neat and compact machine with 1GB of RAM, and a quad-core ARM chip on it. I was looking for an easy-to-carry unix box, and I was wrong: raspberry …

Costruiamo una lampada luminosa con Arduino, un sensore sonico ed…una scatola di uova :) Come abbiamo già visto le scatole traslucide per il trasporto delle uova sono un ottima base per creare piccole lampade, per diverse ragioni: sono facili da trovare sono leggere sono abbastanza rigide possono essere incollate con del Vinavil (strano ma vero) …
In queste settimane abbiamo provato l’Arudino Starter Kit, ed ecco le nostre prime impressioni. Il kit costa sui 105€ IVA inclusa, ed è possibile ordinarlo anche su Amazon.it. La scatola è molto curata ed è accompagnata con un manuale che presenta 15 esempi a difficoltà crescente. Nel kit è fornita una basetta di legno da …
L’Arduino IDE è uno strumento stupendo se non siete sviluppatori software professionisti, perché fornisce un ambiente molto semplice per sviluppare velocemente sketch e progetti Arduino. Se però siete degli incalliti programmatori C++, vorrete qualcosa di più potente, che vi consenta per es di abiliare le funzionalità C++11 del gcc-4.8.x che viene fornito con la tool …
