Using OpenWrt with Yoctopuce USB devices
Do you know which is the smallest and cheapest machine, with Ethernet and Wifi network support, and to which we can connect Yoctopuce sensors and actuators? It's neither the Raspberry Pi, nor the BeagleBone. It's an even smaller machine, sold with an enclosure and a power cord, available in chain stores from $35: the TP-Link MR3020. When you take it out of the box, it's only a simple travel Access Point. But with a few clicks, you can install OpenWrt and new opportunities arise...

Samsung Smart Dock Review
We just found out by chance how to get rid of one of the main hindrance limiting the use of our modules with Android mobile phones: the unique USB port which also serves to connect the power supply. Given that the mobile phone must power connected modules, the phone battery capacity has been a problem so far. What's new is that the "Galaxy Note II Smart Dock" is now available. This dock allows us to realize applications which before required much more hardware. We are going to present a short compatibility example of this device and as well as of the possibilities it provides once combined with our modules.

The quest for the ideal Mini-PC
Here at Yoctopuce, we are constantly looking for the best mini-PC to drive our devices. From time to time, we hear about one which seems to be a good candidate, so we buy one and test it, usually in one of our Friday projects. We mentioned most of them in this blog, but here is a short summary.
