Six years ago, we wrote a post on the influence of the electric resistance of USB cables on the proper working of peripheral devices. Today, we are going to talk about a little-known related problem, which drove us to change our USB cable provider: the shielding of USB cables.
Customers have asked us several times why Yocto-Visualization offers only 4 data series per graph and whether it is possible to have more. The explanation is simple: we had to choose a limit, and a maximum of 4 seemed reasonable. Nevertheless, it's rather easy to modify the application to have more series, and this week we show you how to do so.
When presenting the new Yocto-Meteo-V2, we briefly mentioned that the sensors used in this module are waterproof (IP67 for the SHT35 and IPx8 for the ICP-10100). As we, at Yoctopuce, like to play, we wondered what would happen in we tried to make a Yocto-Meteo-V2 work under water.
Someone recently asked us whether there was a Yoctopuce module which could interface an OMRON V3A magnetic stripe card reader over USB. Although nowadays these magnetic strips are not the most secure way to identify someone, they are still present on credit/debit cards for example. So we took an interest in them.
Now that we finally have our small dry ice freezer, we were able to perform systematic measures of cold endurance for our sensors and transmitters. So here are the tests that we performed and the results.
