Coke + Mentos + Yoctopuce = Fun

By seb, in DIY, november 19,2015.

This week, we decided to write a more entertaining post. It's an experiment to be done with children: adding a few Mentos candies into a Coke bottle to literally create a Coke geyser. The difficulty in this experiment is that the reaction happens so fast that one often finds oneself drenched with Coke. We decided to create a device allowing us to trigger this reaction from afar.

Not long ago, someone asked us whether it was possible to automate a dry food dispenser with Yoctopuce modules, the idea being to transform it into a food dispenser for a pet.

Let's kill the suspense right away: the answer is no, not at the present time. However, we can show you how to build one for a little bit more than the price of a Yocto-Serial.

A Solar, Waterproof and Wifi thermometer

Recently we had to build a device able to measure temperature on a roof. No electricity was available up there, the only technological stuff we could use was a wifi network. That project is not really original since the issues involved have been covered in the mail box and the weather station posts. However we though you would be interested in the box construction....
