A USB food dispenser

By martinm, in DIY, october 23,2015.

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. The answer is obviously yes. There are even several solutions. There is one in particular which is based on a smart use of a Yocto-LatchedRelay which we wanted to show you for a while...

Decoding quadrature signals

By mvuilleu, in Measures and New stuff, october 16,2015.

The Yocto-PWM-Rx is a sensor with two inputs designed to measure electrical pulse trains. Up to now, we measured the signal on each input for itself, independently from the other input. Now, on top of this, you can analyze the two inputs as a pair of quadrature encoded signals.

Java and native access to USB ports

By seb, in Programming, october 09,2015.

This week, we publish a new version of the Java library. This new version comes with a new feature: native USB access. From now on, you can access the USB ports without running the VirtualHub.

Scanning bar codes

By martinm, in DIY, october 02,2015.

At Yoctopuce, we take a picture of each package before we entrust it to the postal services, in case it gets lost during shipment. Up to now, we did this manually by chucking the package on a simple desktop scanner and we saved the file somewhere. But we got tired on this repetitive and completely uninteresting task. So we decided to automate the process...

An NMEA server on TCP for Yoctopuce modules

By mvuilleu, in Programming, september 25,2015.

One of our customers wants to integrate our sensors with software designed for standardized NMEA over TCP/IP sensors (NMEA stands for National Marine Electronic Association). Roughly, a NMEA sensor spontaneously sends its measures at a regular interval, in the shape of a line of text with values separated by commas. The simplest solution is thus to create a small TCP gateway reading any of our USB sensors and periodically sending the measures over TCP to each connected client. As this approach can be useful to others, we coded a short example.
