Most recent cars include a cool gadget: automatic windshield wipers, which start to wipe as soon as it rains. As we are curious by nature, we wondered how car rain sensors work and whether it was possible to build one ourselves, without needing to put a windshield in the middle of the garden.
After the article on the remote controlled camera, we were asked if the Yoctopuce modules could be used to take pictures of scenes notoriously difficult to capture, such as a bursting balloon. We had to respond to the challenge!
Using a Yocto-PowerRelay to switch on a desk lamp from a computer is quite easy. However, to have to power on a computer to switch a lamp isn't really convenient. This week, we present a wiring allowing you to control a lamp both from a computer and from a simple switch, followed by a very handy application: a desk lamp controlled by a screen saver.
Someone asked us recently if it is possible to drive a Canon EOS camera using a Yocto-Relay and information found on this site. We answered yes, of course, but not without a serious temptation to give it a try. Follow the guide, and don't miss the demo !
Someone asked us this week if it was possible to use a Yocto-Knob to detect a contact made by bare fingers, as done by the famous Makey Makey. The answer is yes, of course, but we will not leave it at that... (don't miss the video at the end of the post !)
