In Action

Cloud Ftp Client, is basically web-based FTP client written in Jquery and PHP.  I made this, keeping in mind of those tricky situations when you need it and not have it, and those where your hosting is providing a lame file explorer, or when you need to transfer files to your web hosting account or any other remote server, and you are using computers at some other place, where you do not have desktop FTP client installed, this could help you there. Although this is still in alpha mode, its ready with basic features, I am thinking of new features to add when I find some time; for now it supports one ftp account, it does not save any login details, traverses through directories,display’s current PWD, make new folders, make directory, move it, copy it and delete it.

Communication Mediums: Netduino Ethernet Part 2

Results were not the same, Netduino Ethernet was way faster than Arduino WiFi, no delay’s instant execution, Netduino Plus is bundle of joy for those who wish to build home automation cheap solution with Ethernet and SD-card slot, wins the race again Arduino & Arduino WiFi, making Netduino a web server and parsing data was a breeze and no bugs, I find it to be wonderfully robust, have a look at the video below;
