A few weeks ago, a customer contacted us to know how to upload data from Yoctopuce sensors on a sensetecnic FRED cloud service. We have published a new firmware to make the YoctoHubs compatible with this service. So this week, we will take this opportunity to explain how to use a Yoctopuce sensor in FRED.
This mishap may have happened to you: comfortably lounging at home, you surf on your smart phone. Suddenly, nothing anymore: you have reached the limit of your data subscription. After a short investigation, you notice that your DSL router crashed a few days before and that, meanwhile, you used your phone GSM connection while you thought you were on the Wifi. If only you could have noticed earlier... You are lucky, this week we just happen to discuss a very easy DIY project to signal network failures as soon as possible.
The application that we discuss this week answers an actual problem that we encountered this Summer: how to replace an old float level regulator for a swimming pool, impossible to repair, with an alternative solution which fits in the same small sealed cavity. The main aim is to avoid expensive replacement work. If at the same time we can increase our control on the pool water consumption, it's always a bonus...
You are probably aware of the problem: how to ensure a minimum of security when you back out of a private property in a car, without visibility. Most of the time, people simply back out really slowly and hope that no one bumps into them. But you are still at the mercy of a distracted driver. Hence the idea of a light barrier triggering a light signal to warn oncoming traffic of the danger.
This week, we show you how to build a bar lamp based on RGB LEDs. It's easy and you will end up with something almost as pretty as those you may find in your favorite appliance store. Moreover, each LEDs can be controlled individually, which is not a common feature among design lamps.
