A USB scale without driver

By martinm, in DIY and Programming, april 17,2015.

The Yoctopuce team recently decided to record the weight of each package to be sent, in order to compare the pre-computed weight to the actual weight. And as we don't really like repetitive tasks, we decided to do it automatically. So we bought a few scales with an RS232 output. And this week we take the opportunity to show you in detail how to transform a Kern scale into a Yocto-Scale in a jiffy.

An automatic Nespresso capsule dispenser

By seb, in DIY and Android, february 06,2015.

When one gets a Nespresso coffee machine, the first question that comes to mind is how to organize the different colors of coffee capsules. While chatting with friends about the existing solutions to this "problem", we have been challenged to build an automatic coffee capsule dispenser. Of course, we could not resist...

First tests of the LIDAR-Lite telemeter

By mvuilleu, in DIY, Measures and Reviews, january 09,2015.

When you wanted to measure a distance at a precise location, there wasn't, up to now, any middle range between very expensive laser telemeters (of the Baumer type) and cheap sensors (of the Sharp type). These cheap sensors don't provide a real measured value and are very limited distance-wise. Therefore, we were particularly interested in the LIDAR-Lite project which announced a distance measure of several meters for under $100. Nine months later, the baby is here at last and we can test the final version of the product to try out this new technology.

Interfacing a rotary encoder with a Yocto-Knob

By seb, in Programming, Electronics and DIY, december 17,2014.

We already used the Yocto-Knob to interface potentiometers, buttons, photo-diodes, but never so far a rotary encoder. This week, we are going to see how to interface a rotary encoder with a Yocto-Knob to create a more advanced human-computer interface.
