New demo code which transforms eduArdu in Makey Makey and tutorial how to use with Scratch 3 is uploaded to GitHub.

Here is the result from above code:

New Open Source Hardware board adds SATA drive connectivity to any computer with USB host

USB-SATA

USB-SATA is board which connects to any computer with USB host and bridge it to SATA Hard disk.

The read/write speed with USB2.0 host is approx 30MB/s.

USB-SATA has USB device connector, SATA connector and power connector, when used with SATA-CABLE-SET it can drive directly SATA-HDD-2.5-500GB

It’s very convenient when you have to move large files from one computer to another you can just plug big HDD with it and use it as “giant USB Flash storage” it works faster than the USB Flash disks and can have way larger capacity.

Lime2-SD add on board for second SD card on A20-OLinuXino-LIME2

Lime2-SD is small add on board which snaps on GPIO-1 connector and add second SD card to A20-OLinuxino-LIME2. It doesn’t interference with other parts on the board and do not increase the height.

Lime2-SD

Why we do this? Because this is an easy way to increase storage for Pioneer-FreedomBox-HSK . What we are preparing to offer soon is upgraded version of the Home Server Kit with 256GB storage made with 2 “disks” x 128GB micro SD cards. For these who already have Pioneer-FreedomBox-HSK they still can upgrade by ordering Lime2-SD .

Note that support in FreedomBox for Lime2-SD is not add, but you can try Lime2-SD with the current Armbian image for LIME2. To enable the Lime2-SD support you also have to add this dts overlay .

 

eduArdu OSHW educational board new demo and tutorial updated on GitHub

eduArdu-3

The eduArdu-BotKit demo is uploaded on GitHub. This code control the robot with sound.

New LED_Matrix_Light library is uploaded. It contains only Clear, SetPixel, GetPixel, ClearPixel, Line, DrawRectangle, UpdateMatrix functions and do not take lot of memory like the LED_Matrix library which contains text scrolling and fonts.

Two more demo for capacitive buttons are add. One make sound depend on capacitance, the other prints the value of the capacity measured.

Programming eduArdu with Arduino explains how to install Arduino and some basics of programming for beginners, like what are arrays, variables, etc. It may be used as practice of what is learned in C/C++ class in school.

OLinuXino Open Source Hardware Single Board Linux Computers are now officially OSHWA certified

Ax0-OLinuXino-LIME-1

OLinuXino Open Source Hardware Linux Computers now are officially OSHWA certified. The first: A13-OLinuXino, A10-OLinuXino-LIME, A20-OLinuXino-LIME, A20-OLinuXino-LIME2, A20-OLinuXino-MICRO has their assigned OSHWA certification numbers, the others are to follow as the process takes time.
