Do you remember the GT-521F52 fingerprint reader that we tested three weeks ago? We found a nice and fun application for it...
This week, we are going to do some tinkering and build a hanging scale with a Yocto-Bridge and an Android smart phone. The aim is to weigh objects ranging from a few hundreds of grams to about twenty kilos, in order to weigh objects such a model air planes or bikes. Strangely, two widely popular hobbies at Yoctopuce :-)
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.
