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...

Launching a model rocket without Raspberry Pi

By martinm, in DIY and Internet of Things, august 08,2014.

Not long ago, we came across this post explaining how to launch a model rocket from a smartphone by using a Raspberry Pi, a WiFi dongle, a relay board, and a pocket WiFi router. We wondered if we could make it simpler by using Yoctopuce modules. Moreover, we couldn't pass a reason to play with model rockets :-)

A USB driven turntable

A while ago, we were challenged to build a motorized turntable of the kind used by photographers to take pictures of objects from all angles. The idea was obviously to control the position of the table with Yoctopuce modules. It was a rather ambitious project as there was more mechanics than electronics in it, but we nevertheless took up the challenge...

An Ethernet-enabled scale

By mvuilleu, in DIY, Measures and Internet of Things, july 18,2014.

An automated measure of weight comes in useful for many automation applications: not only for getting the weight, but also for detecting the presence of an object or animal, or even for counting items. So we wanted to experiment with it for quite some time already. But we were missing a key piece of the puzzle until very recently, that is, until the arrival of the Yocto-milliVolt-Rx.

Building a RC car with Yoctopuce devices

By martinm, in Reviews, DIY and Internet of Things, july 11,2014.

During the Yocto-Motor-DC test phase we have conducted quite a lot of experiments to make sure the device would be reliable and would not cause a fire on the first occasion. One of these experiments could be of some interest to you. We have been wondering if it was possible to build a radio controlled car using only Yoctopuce devices...
