If you have been following this blog for a while, you might remember our 2014 Advent window, for which we created an animated landscape in shadow play. This year, we created a new animated Advent window, but based on a different principle: a drawing with UV on a phosphorescent surface, with the help of an embryonic robotic plotter.
This week, we present a small and quite simple DIY project based on the fact that white ping-pong balls make excellent light diffusers. We built a kind of multicolor chandelier, that you can drive through the Internet and which is PoE powered.
The issue with most screens is that they need to be constantly powered to display information. There is however an exception: the e-paper (or electronic paper) technology. This week, we take advantage of this technology to build a connected screen able to work for months on a single battery charge.
IKEA makes pretty ghost-shaped night lights, but the power cable of these "SPÍKA" is very thin. One children has torn this cable and called Yoctopuce for help. At first, we thought that we would simply fix the power cable but, in the end, we decided to improve this night light by transforming it into a "connected night light" with a Yocto-Color-V2 and a YoctoHub-Wireless-SR.
This week, we are going to tell you how we built an autonomous light beacon based on a Yocto-Color-V2. The idea was to take advantage of the pre-programmed sequences of this module to produce light effects which can be seen from far away.
