Automated brightness control for the Raspberry Pi

By martinm, in DIY and Programming, july 27,2018.

Among the accessories available for the Raspberry Pi, the TFT touch display is quite interesting. By combining it with a dedicated enclosure, one gets a tiny all-in-one computer, well suited to monitor various sensors. We like it even more since our YoctoVisualization app now runs on Linux :-) There is only one minor issue with it: brightness control...

Implementing a hanging scale

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 :-)

A connected racing gate for mini-quadcopters

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.
