Using Xively or Emoncms with a YoctoHub

By Sébastien Rinsoz, in Measures and Internet of Things, september 18,2014.

When you simply want to display a physical measure with a Yoctopuce module, there are several solutions: You can write your own program to display the sensor data, or use the embedded data logger with our command line API to export the data. But there is an even simpler solution: configuring a YoctoHub to post the values in the cloud. We natively support Xively and Emoncms, and this week we explain how to configure a YoctoHub to use these services.

An Excel RTD Server for Yoctopuce sensors

By mvuilleu, in Measures and Programming, august 29,2014.

Almost two years ago, we showed you how to access Yoctopuce devices from Excel by creating your own Excel add-in using Excel-DNA. Today we are going to show something simpler and even better: read any Yoctopuce sensor from Excel, with instant live refresh, without even recompiling a single line of code...

Record the lean angle of a motorbike

By Sébastien Rinsoz, in Measures, august 14,2014.

In a motorbike race, the most spectacular is the way drivers lean their motorbikes in curves. Television channels often broadcast videos of on-board cameras and inlay the highest angle reached. For Grand Prix, this information is retrieved by telemetry and broadcasted in real time. But is it possible to produce a video of the same type (but not in real time) using a Yocto-3D and a GoPro?

A USB driven turntable

By martinm, in DIY and Measures, july 25,2014.

A while ago, we were challenged to build a motorized turntable of the kind used by photographers to take pictures of objects from all angles. The idea was obviously to control the position of the table with Yoctopuce modules. It was a rather ambitious project as there was more mechanics than electronics in it, but we nevertheless took up the challenge...

An Ethernet-enabled scale

By mvuilleu, in DIY, Measures and Internet of Things, july 18,2014.

An automated measure of weight comes in useful for many automation applications: not only for getting the weight, but also for detecting the presence of an object or animal, or even for counting items. So we wanted to experiment with it for quite some time already. But we were missing a key piece of the puzzle until very recently, that is, until the arrival of the Yocto-milliVolt-Rx.
