Sometimes you find clues. Sometimes you uncover leads. This group…See More

"Hi David,  Cool, I was thinking that this might work when I finished my build - and you confirmed it! How did you get the picture in picture view? Is it just the laptop webcam, with screencastify recording the whole desktop?"

Recording your dives with Screencastify

We tried something new on our latest trip and test dives in Lake Tahoe. We used Screencastify to record the dives. It worked great!! In addition to capturing footage from the dive, it also captures a small video of the cockpit control room and adds commentary from the pilots. Hard to imagine diving without this plugin…See More

The Art of Planning an Expedition

It's been awesome to watch all the new expeditions pop up on OpenExplorer. One of the important aspects of open sourcing the expedition process is that it shows how important planning and preparation can be. There are dozens of expeditions that are doing a great job with this - check them…

Ok I typed something up really quick. It is waiting or approval. I wanted to get something up asap because I have to head to school. I will add more detail to it later when I have time

I do have a video and lots of pictures of the AUV. I can post up the video now. Where would the best place to put it be?

Thanks for the internal parts once my design is finalized I'll set aside material and machine time for you in case you want some bullet proof end caps.

Hey David,

I'm not sure the correct person to contact, but  I ordered an kit from the store back in October (order number #1261,  ROV serial number #494), but I am just starting to build it now (through step 18). 

I have discovered the kit is missing the following parts:

for Step 21:  

            -Aft battery end cap inner disk (quantity 2)

for Step 23:  

            -large (28 mm) forward end cap disk (quantity 4)

            -small (24 mm) forward end cap disk (quantity 2)

Is it possible to get these parts?  i would happily pay for another complete set of acrylic (spares wouldn't hurt!)...

Thanks and great work!

Paul

Yes it was great to have the opportunity and time on the plane back yesterday. Spent a little time this morning investigating the Maker Movement - very encouraging, much more to explore.

Some highlights from my investigation of Persig's MOQ that you may find interesting:

R. Persig, Subjects, Objects, Data and Values : http://moq.org/forum/Pirsig/emmpaper.html

Which suggests some connections his "Metaphysics of Quality" with Niels Bohr's Philosophy of Complementarity

Niels Bohr, Philosophy of Complementarity : http://en.wikipedia.org/wiki/Complementarity_(physics)

Which aligns the mathematical formulation of quantum mechanics (statistical reality) with the classical formulation of objective reality

From there I ran into these two papers both from 1949 - even the opening paragraphs are good to have in one's head.

Niels Bohr, Discussions with Einstein on Epistemological Problems in Atomic Physics : http://www.marxists.org/reference/subject/philosophy/works/dk/bohr.htm

Albert Einstein's reply : http://www.marxists.org/reference/subject/philosophy/works/ge/einstein.htm

Wandering ruins in southern Mexico between undergrad and graduate school: 1984. Only recently rediscovered the pictures from that trip so I figured, "What the heck!?" :-)

Glad to be here! It's encouraging to us to find groups like yours. And we really appreciate your spirit of sharing ideas and plansand failures and success... and... well, just about everything that goes into the making of a DIY project. :)

Hey David - 

 

I heard you were at the Open Hardware Summit - And I think that we were standing next to a project at the end of the day - I cant remember which one - but (during the demos) - Am I correct? perhaps it was someone else, but I thought that later when looking at your site yesterday -

 

Anyway - I would LOVE to hear, see, experience... some openROV ... I will be at Maker Faire tomrorow  - so , I think you are also? I'll come say hi...

 

Great,

gabriella

 

Really look forward to seeing
