We have now been thinking about a standalone/ondevice solution for our system for many weeks. We gathered and evaluated lots of feedback and came to the conclusion that we need a Brick inside the stack which can be used to run programs for all of our supported languages with our standard bindings. From our view the only possibility to achieve this is to bring a small linux PC inside a Brick. The new planned Brick has the code name "RED Brick" (Rapid Embedded Development Brick). We can imagine three different Options: Option 1: Bottom Side: Board to board and micro SD card Specification: Single Core 1GHz, 512MB Dimensions 4x4cmCan be integrated into a Stack as any other BrickLinux kernel handels SPI communication in stackLinux kernel supports Ethernet ExtensionRetail price (incl. VAT): ~99€ Option 2: Bottom Side: Board to Board and Micro SD card Specification: Single Core 1GHz, 512MB Dimensions ~4x6cmCan be integrated into a Stack as any other Brick. Is larger.Inclusive Ethernet connectorLinux kernel handels SPI communication in stackRetail price (incl. VAT): ~129€ Option 3: Bottom Side: Micro SD card but no board to board! Specification: Dual Core 1,5GHz, 512MB Dimensions ~5x8cmInclusive Master BrickTherefore inklusive 4x Bricklet-ConnectorInclusive Ethernet connectorInclusive Step-Down Power SupplyMaster Brick handels SPI communication, therefore no special Linux kernel needed (no special distributions are required)Retail price (incl. VAT): ~179€Basically this is "Option 2" extended by a Master Brick that is directly connected to the Embedded PC via USB. Additionally there is a Step-Down Power Supply on the board. This is necessary since the board is big and has to be the bottom board in the stack. So it is not possible to put a Step Down Power Supply below. General Informationen: From the users perspective the RED Brick is a "blackbox". This means that no linux knowledge is necessary.For that we plan to offer a web interface which can be used to:Upload programs,configure the execution time,configure if the program should be executed on start,configure if the program should be restarted after a crash,etc.We plan a lot of configuration and diagnosis options (CPU load, logs etc)! There is one problem: This webinterface could be used in option 2+3 with a standard webbrowser. For option 1 an additional Ethernet Extension or WIFI stick would be required.Configuration Alternative 1: Brick Viewer could create a configuration which can be transfered to the Brick by USB stick.Configurations Alternative 2: The micro USB interface could be used to configure the RED Brick via Brick Viewers.The web interface could also be used from smartphones or tablets. Hint: The RED Brick will of course be Open Source. Every user with basic linux knowlege could connect a USB Webcam or play videos over the HDMI port... Followup: In addition to the above mentioned configuration interface (web, usb stick) another configuration option over the mini USB port will be implemented (fallback)As alternative for Ethernet a small WIFI stick could be used (connected to USB Host). Problem here: How to configure it?Option 2+3 does not support PoE, no additional Ethernet Extension is usableSupport of WIFI Extension is not planned. Lower priced standard WIFI sticks can be usedIt is planned to offer a linux image on which compilers (e.g. for C), VMs (e.g. for Java), libraries etc. are preinstalled. Typically you only have to upload your program and it should run on the Brick.Additional libraries can be installed if basic linux knowledge is available (SSH, APT-GET) If you want to vote on one of the options, please do so in the German Thread: http://www.tinkerunity.org/forum/index.php/topic,2127.0.html The options from top to bottom are: * Option 1 * Option 2 * Option 3 * I wouldn't by any of the boards Quote Link to comment Share on other sites More sharing options...
