We have recently found remote-controlled micro-quadcopters, so light that you can use them inside without risk, even in an office environment. Some models are even equipped with a camera, allowing you to fly in FPV (First Person View). If you like learning new things, it's ideal to lighten the rainy days that we have been having early this year.
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.
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.
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.
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.
