A flying plane counter

By martinm, in DIY, august 05,2016.

Not long ago, someone asked us whether Yoctopuce would be interested in creating an ADS-B receiver. We politely declined because we would likely not sell enough of them to cover the development costs. But we suggested that it should be possible to find an already-made receiver and to interface it with Yoctopuce modules. And this week, we prove it...

How many USB devices can you connect ?

By mvuilleu, in Reviews and Tiny PC, august 01,2016.

The USB specification plans for 127 device adresses on the USB bus, and it is tempting to deduce from this that you can connect up to 127 devices on a USB port. Unfortunately, life is not as simple: this naive reasoning does not take into account all constraints imposed by USB controllers. To give you a better and more useful answer, we have decided to test what works in real life...

Managing the heating of a chalet with a YoctoHub-GSM-2G

By seb, in Internet of Things and DIY, july 21,2016.

A classic example of home automation is to remotely manage the heating system of a second home. In Switzerland, many chalets are equipped with heating systems which are managed by a device connected directly on the phone line. Most of these devices work only on an analog line. If you suppress the phone line or switch it to IP telephony, you must change the device. This week, we are going to see how to replace one of these devices with Yoctopuce modules.

Logical structure of Yoctopuce devices

By martinm, in For the beginners and Programming, july 15,2016.

This week, we are continuing our series of articles for the beginners. This time, we will have a look at the logical structure of Yoctopuce devices, and how to use it. If you are a beginner, we suggest that you read this article carefully, as it will allow you to get the best from your Yoctopuce devices.

DipTrace: Make a custom PCB for Yoctopuce devices

By mvuilleu, in Electronics and DIY, july 11,2016.

It is easy to combine Yoctopuce devices to build a complex system, like Lego bricks. But using micro-USB cables for interconnections is often not adequate to make a robust, compact and professional-grade solution. One possible alternative to USB cables is the use of small wires with 1.27mm connectors, much smaller, which can be soldered on all our devices. Today we are showing a second alternative, which also solves the question of fixing the complete system in a dedicated enclosure.
