First tests of the LIDAR-Lite telemeter

By mvuilleu, in DIY, Measures and Reviews, january 09,2015.

When you wanted to measure a distance at a precise location, there wasn't, up to now, any middle range between very expensive laser telemeters (of the Baumer type) and cheap sensors (of the Sharp type). These cheap sensors don't provide a real measured value and are very limited distance-wise. Therefore, we were particularly interested in the LIDAR-Lite project which announced a distance measure of several meters for under $100. Nine months later, the baby is here at last and we can test the final version of the product to try out this new technology.

New Excel plug-in

Some time ago we showed you how to efficiently read Yoctopuce sensors from Excel, using an RTD server written in C# .NET. As this solution works quite well, we have been asked whether it was possible to extend our sample code to handle other Yoctopuce devices. It's Christmas time, here you are :-)

Interfacing a rotary encoder with a Yocto-Knob

By seb, in Programming, Electronics and DIY, december 17,2014.

We already used the Yocto-Knob to interface potentiometers, buttons, photo-diodes, but never so far a rotary encoder. This week, we are going to see how to interface a rotary encoder with a Yocto-Knob to create a more advanced human-computer interface.
