Among the requests that we received in the past few weeks, one caught our attention more particularly: how to interface a Wiegand RFID badge reader via USB, using Yoctopuce modules. It's interesting because Wiegand readers are widely spread in access control systems, and they are readily and quite cheaply available on the net. The good news is that we now have a solution, using a simple Yocto-Serial.
We sometimes have customers who ask us whether we have some ideas on how to check that a display supposed to show videos is actually on and works correctly. It so happens that yes, we have a few ideas :-)
The usual method to detect smoke consists in measuring the reflection of a light beam on the smoke particles suspended in the air. Although we don't explicitly have a smoke detector in our product catalogue, we recently started offering a product which can be used for this: the Yocto-RangeFinder. Indeed, this sensor uses exactly the same principle for its main feature (distance measurement) and can therefore easily be used as USB smoke detector, or even as a networked smoke detector.
Five years ago, we modified our Jura coffee machine, which we nicknamed Josephine, to control it remotely via a web page. The idea was amusing but in fact this feature wasn't really useful as we still had to get up to place a cup in front of the coffee machine. But today, thanks to the Yocto-Proximity, we can do something more useful: We are going to brew a coffee as soon as a cup in placed on the machine.
If you have been following this blog for a while, you might remember our 2014 Advent window, for which we created an animated landscape in shadow play. This year, we created a new animated Advent window, but based on a different principle: a drawing with UV on a phosphorescent surface, with the help of an embryonic robotic plotter.
