Driving a Roomba with a Yoctopuce module

By seb, in Programming and Internet of Things, march 24,2015.

We recently bought a Roomba automatic vacuum cleaner and we started to look at how to hack it as soon as it was out of the box. The Roomba is equipped with a serial port which enables you to control the robot. This serial port uses a Mini-Din socket and works in TTL levels (incompatible with an RS232 port). Luckily, we just announced the Yocto-Serial: a serial interface which can work with TTL levels.

Do you remember the USB desk lamp? This week, we present a WiFi version. It so happens that some new modules appeared since the time the making of the USB version, which make it quite easy to build this improved version.

By Sébastien Rinsoz, in Internet of Things and Programming, october 31,2014.

Some time ago, we found a post where someone had built a device showing his schedule on his office door using Google Calendar. We liked the idea and, this week, we are going to show you how to display your appointments of the day on your fridge door using a Yocto-MaxiDisplay and a YoctoHub-Wireless-SR.

Using Xively or Emoncms with a YoctoHub

By Sébastien Rinsoz, in Measures and Internet of Things, september 18,2014.

When you simply want to display a physical measure with a Yoctopuce module, there are several solutions: You can write your own program to display the sensor data, or use the embedded data logger with our command line API to export the data. But there is an even simpler solution: configuring a YoctoHub to post the values in the cloud. We natively support Xively and Emoncms, and this week we explain how to configure a YoctoHub to use these services.

Resurrecting an old clock

By mvuilleu, in DIY and Internet of Things, august 22,2014.

Somewhere in the middle of rural Germany, there is an old mansion with a front clock, which used to chime the hours once upon a time. It's an old and tired mechanical clock, which was probably never very accurate and which now sometimes stops. As it's not possible to set it to time manually (it doesn't have a free wheel system), it was condemned to a standstill. Until last week, when, with the help of a few Yoctopuce modules, we built a pacemaker for it...
