资源说明：make real espresso using my Android phone
Coffee over anything ==================== Main goal of this project is to allow me to make a coffee early in the morning, while still laying in the warm bed, using only my phone (which I have just grabbed anyway, to turn the alarm clock off). Coffee over USB --------------- [De'Longhi DGI EC5](http://www.shopdelonghi.com/detail/DGI+EC5) is a simple device controlled only by the on-off switch. The switch can be shorted via the relay (I plan to use Mitshubishi Electric SF20-DPS-H1-4), which in turn is controlled by a dirt-cheap Atmega8L microcontroller connected the USB port using simple circuit the [V-USB](http://www.obdev.at/products/vusb/index.html) software. This basically turns the coffee maker into an USB device. Source code for the microcontroller can be found in the [atmega](atmega/) directory. Circuit schematics will be drawn and provided later. For now, look at [the USB-Servo](http://www.schatenseite.de/index.php?eID=tx_cms_showpic&file=uploads%2Fpics%2Fcircuit.sch_05.png&md5=9499241df3382e52f51a60c42206365e53ac1274¶meters[0]=YTo0OntzOjU6IndpZHRoIjtzOjQ6IjgwMG0iO3M6NjoiaGVpZ2h0IjtzOjQ6IjYw¶meters[1]=MG0iO3M6NzoiYm9keVRhZyI7czoyNDoiPGJvZHkgYmdjb2xvcj0iI2RkZGRkZCI%2B¶meters[2]=IjtzOjQ6IndyYXAiO3M6Mzc6IjxhIGhyZWY9ImphdmFzY3JpcHQ6Y2xvc2UoKTsi¶meters[3]=PiB8IDwvYT4iO30%3D) to get an idea. Simple CLI utility for communicating with the coffeemaker's controller is provided in the [cli](cli/). Coffee over HTTP ---------------- That USB device can be connected to anything. In my case it will be OpenWRT-controlled router with USB port (say, TP-Link MR4320). Simple CGI script is provided in the [cgi](cgi/) directory. It should be placed in the /www/cgi-bin directory of OpenWRT router. Coffee via tapping the touchscreen ---------------------------------- Android app that talks to the CGI script to control will end up in the [android](android/) directory. Credits ------- I used hid-custom-rq V-USB example by Christian Starkjohann when writing all of the AVR-related code. The circuit is based on [USB-Servo by Ronald Schaten](http://www.schatenseite.de/index.php?id=219&L=2). WARNING ======= Nobody said dicking around with electric devices is a good idea. On the contrary, IT IS a bad one.
