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

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.

Transforming the Yocto-milliVolt-Rx into a USB ammeter

By martinm, in Measures and Electronics, july 04,2014.

Last week, we presented our brand new USB voltmeter, the Yocto-milliVolt-Rx enabling you to measure voltages with an accuracy of the order of a ten of µV. Obviously, some of you asked: "Can we have the same thing with an ammeter?". Good news: it's almost trivial to transform the Yocto-milliVolt-Rx into an ammeter.

Using the new Yocto-milliVolt-Rx for pH measures

By mvuilleu, in Measures and New stuff, june 27,2014.

After the Yocto-Volt and the Yocto-0-10V-Rx, we add today the Yocto-milliVolt-Rx to our family of electrically isolated voltage sensors. This new module is specifically designed for precision measures of low electric signals, from less than a millivolt to a maximum of 2V. Its design enables a direct measure of very fragile voltages, such as in a pH probe for instance.

SRF06: a cheap range finder

By martinm, in Reviews, Measures and DIY, may 30,2014.

We are often asked if we have any plan for a range finder. Well, the answer is "no, not a this time". However, we do have some reasonable alternatives.
