Running a system on batteries

By martinm, in Electronics, november 27,2015.

As long as your expectations are in line with the laws of physics, it is not a problem to build a battery-powered system with Yoctopuce devices. We have already covered this topic a few times on this blog, but this week we will provide some theory and see how we can compute the life time of a system based on the battery size, how to build a self-powered system, what are the pitfalls to avoid...

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.

Error message: "Another process is already using yAPI"

Yoctopuce support quite often receives calls for help from customers somewhat lost when they discover this error message: "Another process is already using yAPI". This issue is discussed in the documentation of Yoctopuce products but, this week, we are going to take the time to understand where this error message is coming from and how to avoid it.

A WordPress plugin for Yoctopuce sensors

By mvuilleu, in Measures, Internet of Things and Programming, november 06,2015.

We designed the Yoctopuce sensors so that you can easily integrate them in all kinds of computer systems: connecting them to a computer, to an Android phone, or even to a web server. On this latter point, we have so far discussed web integration examples destined to seasoned programmers, working directly in PHP or in Java. Today, we discuss a solution which is simpler to implement for web developers using the WordPress platform.

A $9 CPU to use our modules

By seb, in Tiny PC, october 30,2015.

As you might have guessed, at Yoctopuce we like to try out new computer and electronic gadgets, and especially so when it's possible to use them with our modules. A few months ago, Kickstarter financed a $9 "computer": C.H.I.P. We backed this project enthusiastically, and last week we received the Alpha version of this mini-PC.
