Outdor electronic projects

By martinm, in DIY, october 28,2011.

When we start thinking about an outdoor electronic project, some new problems appears. The worst one is humidity, everyone knows that electric stuff does not like water. Fortunately, there are ways to make an electric device work outdoor. This article explains some techniques to help you use Yoctopuce devices in the wild.

The USB Pumpkin in the Cloud

By martinm, in DIY, october 21,2011.

Getting into Halloween time, we thought it could be fun to show a Yocto-Color used within a pumpkin, and to use its RGB leds to change the pumpkin color. Nothing really special, actually. To make it a bit more challenging, we thought that it would look much better if we could have some kind of cloud floating around the pumpkin. Forget the small demo that we had originally planned, our pumpkin just bubbled into a big overkill...

Pimp My Mouse

Today’s article is about a useless, but nevertheless quite impressive piece of fun. Gamers know the excellent Razer mouses, mostly known for their precision, but also for their typical illumination inside the mouse. However, this illumination cannot be controlled. Hence the idea to put a Yocto-Color module inside the mouse, to be able to dynamically change the mouse color using our USB-driven RGB leds. More details and even a video after the break...

A tiny USB hub

There is generally no problem to remotely drive a legacy appliance using a USB device from Yoctopuce. It is actually quite simple: disassemble the appliance (without losing the screws), install the module in it (without forgetting to put a USB cable to the outside) and reassemble the appliance (using as many of the original screws as you can figure out). Given their average size of 20x45mm, Yoctopuce modules are generally small enough to fit anywhere.

Now, when you need to put several USB devices in an appliance, it is a different matter. Stuffing the devices themselves is usually OK, but then you need to add a USB hub as well, and all the cables with their big connectors...

Yoctopuce libraries

People often ask how we manage to drive our USB devices using programming languages such as Javascript. Just for once, let's go for some slideware.

We provide three kinds of libraries to drive our USB devices: native libraries, dynamic libraries, and libraries requiring a virtual hub. All are available with source code.
