A network humidifier in an afternoon

By Sébastien Rinsoz, in Internet of Things, march 13,2014.

When we founded Yoctopuce, one of the aims was to provide a fast, easy, and reliable solution for any geek DIY (controlling the coffee machine from your computer, knowing when to fetch the mail, and so on). Other solutions were already available, but none was simple enough for everything to work in half a day. This week, we had to quickly install a system to control humidity in a bedroom, and we had only an afternoon to do it. Here is what we did...

The return of the Yoctopuce mailbox

By martinm, in Internet of Things and DIY, february 21,2014.

Do you remember the laser mailbox? It works quite well, but we noticed a very annoying defect. Because the mailbox is made of metal sheets, it tends to slightly deform itself depending on temperature changes. This deformation changes the laser beam trajectory inside the box, sometimes to the point of bringing it off the light sensor target. Therefore, we had to regularly adjust the mailbox to solve this issue. After a while, we had enough and we came up with another idea to fix this. But this time, we are seeing big: we are going to render our mailbox autonomous thanks to a solar panel and a Wifi connection.

New data logger and graphs under Android

By Sébastien Rinsoz, in Programming, Measures and Android, february 17,2014.

Last week, we used the new version of the library to trace a dynamic graph in C# .NET. At that time, we saw that the new Datalogger API and the TimedReport made the work a lot easier. This week, we are going to develop a small Android application that also traces a graph from the datalogger and from current values. But we are going to see that things are a little more complex under Android ...
