Where Arduinos are Born: Touring a PCB Factory @ bunnie’s blog – [via]

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.

I have made a 16×8 led word clock, a rectangular one. Break from square or almost square ones. This one is a complete modular design and can be scaled up or down in size / complexity according to ones need. The whole design and requisite files are in open domain and the project has also some good 3d pcb renders. The main clock controller is arduino-like and is again scalable.

The LED panel is composed of 8 individual panels of 4×4 LEDs. Each group of 4 such panels will be controlled by a MAX7219. Here are the schematics and board layouts of the 4×4 LED board and LED driver … They are on the way to a fab house….In the meantime I shall do 3D render of my project. Schematics & PCB designed using Eagle CAD 6.2.0 Lite Running on Linux Box.

A little known feature of Arduinos and many other AVR chips is the ability to measure the internal 1.1 volt reference. This feature can be exploited to improve the accuracy of the Arduino function – analogRead() when using the default analog reference. It can also be used to measure the Vcc supplied to the AVR chip, which provides a means of monitoring battery voltage without using a precious analog pin to do so.

O’K, after having some fun with stereo version of the VU meter I described in my previous blog-post, now it’s time to do a serious stuff. Studio grade VU meter !!! 24 steps, equally spaced every 3 dB, covering Extra wide Dynamic Range from -63 up to +6 dB. Single (mono) channel this time, no messing around, absolute precision at the stake. Plus, it keeps absolutely Top-Flat linear frequency response from 40 Hz up to 20 kHz(*).

Are you considering using Arduino for your next high-tech project? Think of it twice! Check vpapanik.blogspot.gr opinion about using Arduino for advanced projects.

Arduino is a must-have these days.

It’s a great microcontroller-based prototyping platform, coming into many flavors, with tons of open source projects, tutorials, forums etc. for anyone to start playing with embedded hardware. Using a simple IDE and C++ based code, a USB cable and a few passive components, it is possible to blink a LED in seconds or exchanging messages with a PC (well, a Mac too) in a few minutes, without any serious prior knowledge in electronics.

It’s undoubtedly an excellent starter, but how far can you go with an Arduino ? well, pretty far, but up to a point because (as generally in life) there’s always a tradeoff between simplicity and performance. It’s up to the engineer/maker to decide if and when.

The idea behind this post is to bring together some robot designs and transform them in a new device with new hardware and standard software (arduino of course) and so easier to use.  These robots have three things in common: a mechanical structure, the hardware and the software. While the mechanical part is necessarily different, we wanted to understand if there was a hardware board that could be common, with a unique development system. The choice, quite obviously, has the Arduino board, which with its development environment is perfect to create similar projects.
