Cook and Hold with Raspberry Pi (video)

By Sébastien Rinsoz, in Measures and Tiny PC, october 01,2012.

When we geek try to cook a nice chunk of meat, the tricky part is the cooking itself. Instead of sitting idle while the meat cooks, we go read something on the iPad, code some stuff or even to talk with the guests rather than watching a meat in the oven. And at the end, the meat is often overcooked. But this is gonna change. Our new recipe, using a Yocto-Thermocouple and Raspberry Pi, solves the issue. The Raspberry Pi will monitor the meat temperature for us, and send an e-mail as soon as the ideal temperature is reached. And long life to the smartphones !

About sensor calibration

By mvuilleu, in Measures, august 31,2012.

All of our USB sensor modules perform their measurement with the help of digital sensor chips, which are factory calibrated. It's our recipe to guaranty the announced precision of our modules, even when the sensors are moved away. However, we have recently introduced in all our sensor modules an additional adjustment function, allowing your to perform a correction to the measures on the fly. So, what's the need to correct a measure if it is already good? Doesn't this recalibration risk to reduce the measure precision rather than to enhance it?

An embedded ammeter

By mvuilleu, in Measures, may 11,2012.

When you build an electrical circuit requiring some power, for instance in a remote controlled scale model, it is essential to correctly size the wires and the battery. If the wires are too thin, they transform themselves into an electrical heater; worse, if a LiPo battery is undersized, it can transform itself into an incendiary bomb... The problem is that power consumption can be measured only in real life circumstances, when the motor (or any other consumer) is really working. Thus, it becomes interesting to use a small embedded ammeter from which you can read the measures later by USB. This is the perfect opportunity to present the Yocto-Amp, our new product.

The USB data logger

By mvuilleu, in Measures, february 06,2012.

One of our customers recently noticed that the description page of our temperature, light, humidity, and pressure sensors mentions the capability of recording data to a flash memory. The documentation however does not cover this topic, and there is nothing about it in the programming library either. It is now time to fix that...
