Extending RaspberryPi, BeagleBoard, Arduino ... with lots of I/O's?

Dear reader,

How to extend RaspberryPi, BeagleBoard, Arduino ... with lots of I/O's? My friend and I developed a solution. We launched a Indiegogo campaign where we offer a series of digital I/O modules: http://igg.me/at/kunio

Via an SPI bus + some I/O pins, or just up to 7 simple I/O pins, you can add a huge number of digital in- and outputs in a modular way. By using any microcontroller or Single Board Computer of your choice (RaspberryPi, BeagleBoard, Arduino,...), you can create a powerful device (PLC) that is accessible from the internet and has lots of storage and features using your own development tools.

If you are convinced of these products, please help us raising funds so we can produce our first modules and bring them to market! The next step is to add more analogue inputs and outputs to this concept, without the need for more I/O pins. I hope you enjoy this...

RPi compatible, waterproof screen?

Hi, I'd like to turn my RPi into a speedo (instrumentation display) for my motorbike. That means I need a small waterproof LCD to hook into the RPi. Does anyone know of a good screen for this type of application or can link me to an option or 2?

Many thanks.

Jaymin,

This forum is for discussions about the elinux wiki, and not for general embedded linux support.

Beaglebone black - no mass storage seen

I bought a Beaglebone black a week ago and cannot get it running. I have a normal Beaglebone that works fine, but the black just does nothing. It seems to boot according to the LEDS, but I do not get a mass storage device registered. I have tried different cables, computers on both windows and Linux. I have tried the procedure described on eLinux.org for trouble installing USB drivers, but when I run EEPROMA5.BAT it fails with the message "No devices found" and in red "Device 0 does not exist"

I do not know what else to try.

I would suggest posting your problem to the Beagle mailing list here:
