USB water rockets

By martinm, in DIY, november 21,2013.

Last week, we built a water rocket launcher. This week, we deal with the sister issue: the water rocket itself. And because at Yoctopuce we can't help putting USB modules everywhere, we built a USB water rocket...

You probably heard of water rockets and might know that it's quite easy to build them yourself with soda bottles and hose nozzles. This type of "toy" can be propelled to quite breathtaking heights, which makes it a rather fun hobby. Well, Yoctopuce looked into it...

Yocto-4-20mA-Rx: the answer to exotic needs

Customers regularly ask us whether we don't want, by any chance, to build a module to measure [insert a physical quantity here]. Sometimes, we jump into it, but we sometimes also decline because the resulting module would be too specific. Therefore, we would likely be unable to sell enough modules to amortize the development costs. We thought about the issue, and we think that we have a reasonable solution.

Weather station: display

By martinm, in Programming, october 31,2013.

Last week, we built a solar weather station which posts its data on xyvely. It's convenient, but it would be simpler to be able to consult the data without having to turn on a computer. This week, we tell you how to show this data on a Yoctopuce display. This requires some programming, but nothing too complex. If you wish, we can do this together...

Do you recall the solar box? Actually, it has never worked well enough to be useful. Here at Yoctopuce, it has been renamed the NULL box. Ruthless, but not so far from reality. But this week, we have a new version of that experiment. This time, it is much easier to make it work because we now have hardware designed with that kind of application in mind.
