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.

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.

Lighting a model runway with a Yocto-Color-V2

By seb, in DIY, november 17,2017.

The guys at Yoctopuce love rc modeling and particularly everything that flies. Unfortunately in Winter, the sun goes down early and flying sessions at the end of the day often finish up in the dark. We decided to build a small lighted landing runway that we could control from a smart phone.

Simulating large current consumption

By martinm, in DIY, november 10,2017.

When you perform endurance tests with electronic circuits, you sometimes need to simulate a large current consumption. At first sight, this seems rather trivial, but don't get it wrong: there are a few hidden pitfalls which are only waiting for you to make a mistake in order to sabotage your experiment. This week, we show you how we built a small box with a consumption that we can drive by USB.

Signaling network failures

By martinm, in Internet of Things and DIY, september 08,2017.

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.
