Set video to public.

Your youtube video is set to private. Can you change it to public (anyone can see it) or unlisted (you need a link to see it) please?

Thanks!

Sorry for the lack of updates. I lost most of the source files to a crash, but I am almost done reconstructing them from the stl files.

Also, if anyone is curious, this was made in Sketchup and Blender.

Sorry for not updating it for a while, but I am stumped on how to make the carry mechanism. Any ideas would be welcome. I looked at the carry mechanism on the original design, but it would be too weak if it was made out of plastic.

qwertyzzz18 on August 28, 2011 said:

Also, has anyone printed it? I need to know if the gears are large enough to mesh reliably.

If not, i will need to split some of the pieces.

qwertyzzz18 on August 28, 2011 said:

The way it needs to work is:

The ridges on the figure wheel will 'trip' the carry mechanism, and put it in a 'set' state.

When triggered, it will advance the figure wheel above one place, and return to a 'reset' state.

Any help would be appreciated.

THis is sooooo cool. I always wanted a 'complete' analytical engine maybe this is the way - 21st century manufacturing of 18th century design.

Wonderful! How many parts to go?

qwertyzzz18 on April 27, 2011 said:

I need to work on the carry mechanism.

It looks like someone read my mind. This can easily become the coolest thing on earth to be 3d printed.

I can't wait for this to be completed, might need to order more ABS though...

Wow! Just Wow!

UNBELIEVABLY COOL. Seriously, this is phenomenal work...

SayNoToMakerbot on April 6, 2011 said:

Do you realize that posting the parts separately makes it a huge pain. Clicking on the parts list does not take you to the other "things" that you have made as parts. WilliamAAdams tried that with his polybot and it was such a pain that Renosis re-posted it all in one here http://www.thingiverse.com/thi...

Although if Thingiverse worked that way it would be sweet.

qwertyzzz18 on April 6, 2011 said:

Sorry. Can I use the part list and upload everything on the main project?

tbuser on April 6, 2011 said:

Wow, I hope you can make this work!
