David,

I noticed all the work you've been doing lately.

Thank you. --Sebastien Bailard 04:36, 23 April 2010 (UTC)

Re:Thank You

David,

Thanks for taking a look! Unfortunately, I've been swamped lately, and progress on the Mendel that is going to build the TRap has slowed to a crawl. I hope to address your comments here:

  1. I really enjoyed seeing the T-rep. Looking at the wiki page and blog was pretty cool. I hope that my design gets that far, in terms of workability. TRap (Pronounced as a single unhyphenated word: "trap") is a development name, and will eventually be changed - if the project ever gets to a usable state. At that time, I'll appropriate the name of some pioneering and iconoclastic biologist. For the moment though, I'm going to stick with it, as that is the name which ties all my design files together.
  2. I'm not sure that I understand your comment here. The sketch is not entirely clear, as there are no motors shown. Each motor-leadscrew assembly will connect a corner of the base and the outer (furthest from center) free corner of a tetrahedron. Both of these conections will need to pivot to allow the tetrahedron to move properly. The joint at the base is a simple pivot. The joint at the corner of the tetrahedron is a bit more complex, as it contains the leadscrew nut, which must pivot. The actual design of the tetrahedron at that point needs to be worked out, mostly so that the leadscrew does not crash against the tetrahedron when it is fully retracted.

And your question:

I don't know. I hope that I can use an existing firmware, as that would reduce my task list substantially. (And I know very little about uC programming. I'll always welcome competent help (in any aspect of this project), so if you are interested, or know someone who might be, please let me know.

Thanks for taking a look at my project! I hope to hear more from you.

P.S. I've already posted this to my talk page. (I'm posting it here to make sure you get my reply.) P.P.S. I just checked out the Delta page on the wiki. I'd seen Reinoud's stuff elsewhere on the web, but didn't know it had it's own wiki page. I'll have to go through that in more detail later and see what they've come up with.
