Some of you might have read my post on Whirligig https://www.robotshop.com/letsmakerobots/node/16995 and its predecessor SEA RENDERING https://www.robotshop.com/letsmakerobots/node/21098 , and know that it was original designed to measure depths in lakes. When SEA RENDERING took …

Great! An other great project from you my friend,with lots of informations,great pictures and also VERY inspiring. Thanks for sharing,it’s always a pleasure to read and watch your great creations. :slight_smile:

Awesome The overall design of this project is so impressive, that I hesitate to bring up a tiny detail. But you choose to hang with us nitpickers. So here you go. The micro switch seems flimsy. It might be triggered at the slightest touch. A bit of weed floating in or on the wat…

Thank you for your input Thank you for your input Rik, and I do agree with you on the micro switch. The fact that the micro switch might misfire ones in a while is not critical to the mission as all the data will be interpolated later. And all a misfire does is cut this trip t…

Switching from Arduino to Switching from Arduino to FEZ domino should be very easy. OK, you have to learn a lot at the beginning, when switching to a new platform. But if you are familiar with .NET this should be an easy step. Porting the Arduino code will maybe a challenge, but…

Now I know what the thin Now I know what the thin wire that you do not need was for :slight_smile: Really cool project as always, thanks for all the material, Geir!

I see I understand that an interrupted trip down is not as serious as I thought *). I envisioned a bot in the middle of a lake with its probe dangling 10+ meter below its belly, not knowing what to do because the switch was jamming. *) Could whirligig still travel with a danglin…

You sparked an idea Rik ! Whirligig could be running even if the probe isn’t in ’park’ position, but you should get a warning in the control panel. The winch board has the following logic built in to it. One pin controlled by the Arduino triggers the oscillating and as long as i…

I’m quite familiar with I’m quite familiar with .NET and the Visual Studio IDE as I’m a professional programmer and have been working with ASP.NET sins its first release. I have only worked on web applications but the framework is not new to me. I’m still waiting for my FEZ Domi…

Thank you Fritsl, you Thank you Fritsl, you obviously keep a close watch on the forum, -and yes this project was what I wanted the thin wire for. As it turns out I think the new design will work better with a self-contained probe operating independently from the mother ship.

Thank you for your kind words and positive comments

That’s why I love LMR and the people here that make this site so interesting. I’ll update this post as the work progress and add some video when we get Whirligig in the water.
