My inspiration for developing this gas gauge was after purchasing a new car (Scion Xa) and wondering what MPG I was getting. After much research on ODBII protocols (Scions support CAN-BUS), and looking into open source software that already existed (OBDuino32K) I delved into my first Arduino project.
This project has taken me over a year to put together from building my own CAN-BUS shield, learning to design a circuit board, soldering SMD parts and then building my own enclosure so I could mount it in my car.

Small Arduino compatible USB host board. Take control of your Android phone or other USB device in your next project.
This project began the day I saw the Google IO 2011 talk about the new Android Accessory Development Kit (ADK). I had never seen or used an Arduino before. I had written a few Android programs but something about being able to connect custom hardware to my phone inspired me to start this long trip down hardware lane. Specifically, I was inspired to create motorcycle navigation software knowing that I would be able to create a remote control for my phone that would allow me to control the software with gloved hands. I finished the navigation software a few months later, and it has been a great success. This board has allowed me to complete that project; I now have a remote control attached to my motorcycle.

The Story: We set out to build a little brother to the wonderful Arduino line of development boards – we were tired of leaving our valuable Arduino’s behind in projects, or worse, ripping apart old projects to build new ones! We also felt the Arduino was too big and powerful for many projects where we only needed a few pins, or an SPI or I2C bus. And so the Digispark was born! To us, the best things about the Arduino is the community, the easy of use, and the IDE – by making the Digispark an Arduino compatible development board all of those remain common. Plug it in, power your project with USB or external sources, program it with the Arduino IDE, and easily use existing Arduino code! But with its small size and low cost you can feel free to leave it in your project, give one to a friend, and use them everywhere!

So who’s behind RadioBlocks? A group of engineers who have worked on many aspects of low-power radio devices. A group of engineers who time & time again saw customers coming to us with similar requests, but with no way for us to easily fill them. So we created RadioBlocks to allow people to easily drop a radio link into their project, hence “RadioBlocks” – A simple to use radio building block.
Sure there are lots of radio boards out there. Most have two modes: super-simple serial-port replacement mode, and complex full network mode. Neither of those are useful – most people want to send some data between some devices. They need more than serial-port replacement, but the full network mode is too much hassle. Then many of those radio devices are just too expensive – are you really going to drop $30 or $40 on a single radio node, then buy extra hardware so you can attach sensors? Good luck with that!

Teensy 3.0 is a small, breadboard-friendly development board designed by Paul Stoffregen and PJRC. Teensy 3.0 will bring a low-cost 32 bit ARM Cortex-M4 platform to hobbyists, students and engineers, using Arduino(R)** or programming directly in C language.
Based on a 32 bit ARM chip, Teensy 3.0 aims to greatly increase the computing capability and peripheral features, but maintain the same easy-to-use platform that has made Teensy 2.0 so successful.
Teensy 3.0 has been in development for well over 1 year. Many prototypes have been built. The photo above is the final prototype.

Arduinos are made in Scarmagno, Italy, a small town near the Olivetti factories on the outskirts of Torino. All of the circuit board fabrication, board stuffing and distribution is handled out of that small town. I was really excited to see the factories, and I’d like to share some photos of them with you. The highlight of my tour was “System Electronica”, the PCB factory which makes the Arduino PCBs.

This is a shield for Arduino designed and based on the module GSM/GPRS SIM900 or the GSM/GPRS & GPS module SIM908, to make calls, voice and data connections via GPRS. This new version has several new hardware features, that allow maximum customization and provide many configurations. With a microphone and a headset with a 3.5 mm jack (just the standard headphones for computers), you can make a voice call from Arduino!!

A tachometer is a useful tool for counting the RPM (rotations per minute) of a wheel or basically anything that spins. The easiest way to build a tachometer is using a transmitter and receiver. When the link between them is broken, you know that something is spinning and can execute some code that calculates the current RPM of whatever is spinning to break the transmitter/receiver link.
In this article we will explore how to use an IR transmitter and receiver break-beam pair similar to the PIC Tachometer project I built a few months ago, but because of popular demand, the Arduino system will be used for all the processing and break-beam interruption counting. The end result will be a 16×2 LCD displaying the RPM of some computer fans.
