Open Source development board but also a Solar BMS for any type of Lithium batteries and supercapacitors for anything that needs power for me is the OffGrid House and a solar powered robot.
Based on ARM cortex M0 and has a USART port that if connected to a raspberry Pi running an web-server may be use for remote monitoring of the power generation.
It can be used with 3s up to 8s Lithium cells and self power consumption is just 25mW
Can raspberry Pi be in sleep low power mode and wake up by Solar BMS optically insulated USART?

Hi guys! I have a wonderful Rasberry Pi and I would like to turn it into a Nas, so, searching on the internet, I found that it's possible with OpenMediaVault. I follwed this guide
http://www.morganino.it/technology/installazione-openmediavault-su-raspberry-pi-mod-b-rev-2/
but I have some troubles at the end of the installation.
Here's the error:

Si sono verificati degli errori nell'elaborazione:
 nfs-kernel-server
 resolvconf
 smartmontools
 proftpd-basic
 proftpd-mod-vroot
 tftpd-hpa
 snmpd
 quota
 watchdog
 openmediavault
E: Sub-process /usr/bin/dpkg returned an error code (1)

I'm sorry...it's in italian, but I hope someone would understand and help me
Thanks a lot

raspberry pi on my face

here is a raspberry pi goggles project i that i'm almost done the initial build on.. this pi i call goblin.. just need to wire the level shifter to connect the raspberry pi and arduino (i've been using usb for previous projects), properly mount the accelerometer (using packing tape at the moment), and waiting for the video glasses screens part to come in.. using the 320x240 video screen insert from these .. https://www.adafruit.com/products/1452 .. 320x240 will work well for me with the raspberry pi, especially when i start to play with opencv on it ..

.. you can see no ir filter pi camera board mounted in the front, have 50 IR leds to wire up and test out IR night vision.. mounted in the front is also a sonar range finder, gauges distance from 10 cm to 3 meters by bouncing sound, like a bat .. inside the front box is a triple axis accelerometer with compass, so the arduino/raspberry pi always know which direction the head/camera/sonar range are facing .. as the head is moved around, the distances, matched up with the direction facing, and tilt angle, will be recorded to a database.. on the screen, as the head is moved, the non expired data will be accessed,represented as far away readings being black and closer distance readings on a gray scale with white objects being very close.. sonar vision, like on fishing boats .. will have to attach some small microphones and boost the gain for more sensitive hearing .. i have a few more sensor ideas to eventually test on the platform ..

never hurts to have your batteries topped up at any time, useful for charging anything during the day as well as Pi related dark goggle business ;-)

Has anyone managed to compile/port node-webkit for the Pi or anyone has a binary for it?
https://github.com/rogerwang/node-webkit
It appears that it is quite the task and I have not found much information for the porting apart from a couple of outdated discussions and guides.

Ok so imagine the year is 1973. All the talk is about a new arcade game which has been released by Atari. That game is called Pong. Now it might not seem much of a game by today's standards, but it was a massive hit in its ...

My desktop computer crashed recently and the disk was corrupted, so instead of taking a new one I was thinking of using the Pi. Is it possible to boot windows from the Pi or only Linux distros work on the Pi?? Can I connect a harddrive externally to the Pi and boot windows from it???

+Allen M. I did not mean to say that Windows would run on a Raspberry pi. I simply wished to state that Microsoft does develop and make a version of Windows for ARM processors. I did not know specifically V7 of ARM.

How to set up a lightweight web server on Raspberry Pi
#raspbian  
There are a variety of web server software available for Linux-based platforms including Raspbian. Using the available web server software, we can turn Raspberry Pi into a 24/7 available portable web server. In this case, however, we must remember that Raspberry Pi has hardware limitations in terms of CPU clock speed, memory, etc. As such, …Continue reading...

My review of  "Raspberry Pi Projects for Kids" by Daniel Bates
http://www.packtpub.com/raspberry-pi-projects-for-kids/book

This book presents three original projects. There is a Scratch-based project, a GPIO/Hardware project using Python, and a Python-GUI project.

Before reviewing the projects, I would like to comment on a trend found in most, if not all, books dedicated to the Raspberry Pi. It is my hope the future authors of the genre will see that there is no need to include what seems to be a mandatory chapter dedicated to setting up the Raspberry Pi or preparing the SD card with the latest Raspian distribution. A links to the most up-to-date Raspberry Pi Foundation "Quick Start Guide" web page (http://www.raspberrypi.org/help/quick-start-guide/) does a good job at this and also serves as a good example on how to find information related to hacking away with the little computer that can. Readers would then be rewarded with books entirely focused on projects. To finish on this rant, I was glad that there was no 'Python 101' pre-introductory chapter that also plague several Raspberry Pi books.

Now that I've almost fallen into the trap I was criticizing, let's get down to the projects business. The first project is about programming an Angry Birds type of game. This one reviews the Scratch interface (good job at keeping it down to three pages) and the various components of making a video game. Those seeking a quick step-by-step recipe might be in for a disappointment as the instructions are focused on designing the functionalities of the game. This is a good base for learning how to design a program. I will most likely end up using some of this material to teach my own students.

I really liked the 'Testing Your Speed' project. This one will end up in my own lesson planning. This project exploits the Pi's GPIO pins by building a controller made out of office materials such as paper clips and fasteners and sticky tape. I liked that apart from obtaining male-to-female wire and/or a Pi Cobbler breakout board and a prototyping breadboard, there was no need to order other components. However, the chapter's layout would benefit from clear and obvious warnings regarding the dangers of shorting the wrong pins on the GPIO ports as it looks rather diluted within the bulk of the copy.

Finally, the last project is about making an interactive map using Python and its GUI modules. The project relies on using the Google Maps API to obtain mapping data. A list of widgets presented at the end of the chapter outlines valuable extension potential from this project.

While this book is not recommend for elementary school age kids, I definitely recommend it to teachers and parents seeking to support kids learning how to code.

Hello guys

I bought a board DVK511 for my raspberry pi and I cannot use the 1602 display that come with kit.

Anyone had any issue with this display or anyone known how to use this board correctly, because the manual is poor. 

Thanks a lot.
