Surfing on Ebay and youtube, looking for some servos, i found this very well done video on how the servos work, from the inside to the outside.
A really nice 3d modeling video explaining how the servos work.
Mauricio from Mexico has done this great arduino project: The Flush-O-Matic. It´s a device to auto flush the WC and see the progress of the process via an LCD screen. It works via a servo motor that makes the mechanical action, and a puschbutton to start the process. Grat idea… Just an amazing project to do with your Arduino (or compatible) board... one image (or a video) is worth more than a thousand words this time. (Video Below). You can say this is a "full time" job for an arduino... and in the end, a clock work is timeless? ;)… It´s Summer time!!!! (it means we have some crazy hot days in Madrid... 40º C!!!!) This summer has been quite complicated in Spain, and in my flat i don´t have air conditioning, so i needed to have a solution fast, since the fan was not doing enough... i came up…
