Cheap and compact cold

By martinm, in DIY, december 22,2017.

Three weeks ago, we built a "hot box" that can maintain a small enclosure at a constant temperature in the order of 85°C during a few hours. This week, we are trying to do the opposite: a "cold box" that can maintain an ambient temperature in the order of -30°C.

Temperature tests on Yoctopuce devices

By mvuilleu, in Electronics and Reviews, december 17,2017.

You may have noticed that until now our module specifications didn't include a working temperature range. This omission could seem strange, but we didn't want to give raw numbers without accompanying them with some explanations. Indeed, although most of the modules were designed for an extended temperature range, we hadn't had the opportunity to formally valid the theoretical temperatures. Thanks to the small system built two weeks ago, it's getting ready.

Adapting monitor brightness automatically

By seb, in Programming and Misc, december 08,2017.

This week, we are implementing a program suggested by one of our customers: Using the Windows API to adapt the brightness of a monitor depending on the ambient light. Most laptops already do that, but desktops don't because they don't have a light sensor. We are going to use a Yocto-Light-V3 to determine the ambient light.

Building an oven and its regulation

By martinm, in DIY and Internet of Things, december 01,2017.

We recently decided to systematically test the behavior of Yoctopuce modules when they are submitted to high temperatures. We therefore had to build an enclosure able to heat up and maintain a relatively precise temperature. This week, we show you how we built it.

A gateway to remotely access YoctoHubs

By mvuilleu, in Internet of Things and New stuff, november 27,2017.

Today we present a new tool which you'll find very useful if you use Yoctopuce modules in a protected network environment, such as behind a NAT filter or a firewall. If you have ever wished to remotely connect to your devices for an interactive session, for instance to modify the configuration, you will be glad to know that this is now possible... even for YoctoHub-GSM!
