Variations on the Makey Makey theme

By mvuilleu, in DIY and Tiny PC, february 22,2013.

Someone asked us this week if it was possible to use a Yocto-Knob to detect a contact made by bare fingers, as done by the famous Makey Makey. The answer is yes, of course, but we will not leave it at that... (don't miss the video at the end of the post !)

Using the Raspberry Pi as home automation gateway

By mvuilleu, in Internet of Things and Tiny PC, february 01,2013.

Following last week's article, here is a small real-world application using HTTP callbacks to drive Yoctopuce modules through a NAT filter. We will use here a Raspberry Pi because it's cheap and we don't need too much out of it: only to run a VirtualHub to generate periodic callbacks.

API update and new performance measures

By mvuilleu, in New stuff and Tiny PC, october 12,2012.

After several days of testing, we published this week a new version of the programming libraries (API) for all the languages, as well as a new version of the VirtualHub software, allowing you to reach our USB modules through the network. New or improved features are:
- improved ARM support (MK802, MK805, and Raspberry Pi)
- access control on network connections
- HTTP callback in the VirtualHub
- improved performances with all the languages

Cook and Hold with Raspberry Pi (video)

By Sébastien Rinsoz, in Measures and Tiny PC, october 01,2012.

When we geek try to cook a nice chunk of meat, the tricky part is the cooking itself. Instead of sitting idle while the meat cooks, we go read something on the iPad, code some stuff or even to talk with the guests rather than watching a meat in the oven. And at the end, the meat is often overcooked. But this is gonna change. Our new recipe, using a Yocto-Thermocouple and Raspberry Pi, solves the issue. The Raspberry Pi will monitor the meat temperature for us, and send an e-mail as soon as the ideal temperature is reached. And long life to the smartphones !

Yoctopuce modules, MK805, and solar panels

By martinm, in Reviews and Tiny PC, september 14,2012.

There is one question which comes back rather often in the Yoctopuce team. Here it is: How to make Yoctopuce modules work in the middle of nowhere, in the back of the garden, for instance?. Indeed, it is unlikely to have an electrical outlet in the back of the garden, without even talking about a USB connection. In the opposite, there is sunshine, and we can easily make sure that we also are within a Wifi range. We are not solar specialists, but Yoctopuce modules consuming an average of 125 mW, it shouldn't be all that difficult to make them work with a solar panel...
