Photo Galleries are back! Instructions below.

Dear forum users,
Thank you for your patience with the Photo galleries. We've got your galleries online!
We have finished writing a custom script to migrate the PhotoPlog to vBulletin5’s albums.

Unfortunately V-Bulletin killed the "Photoplogs" in their software upgrade which was unforeseen and we're the first development group to have written a script for getting the galleries back... that said, it took some time to reverse engineer the code and get the albums to move over seamlessly!

Forum users will be able to access their “PhotoPlog” images through their user profile page by clicking on the “Media” tab.
They will also be able to browse other albums by going to the albums page. (On the forum site, there is a link in the black bar beside “Forums” to the albums.)

In order for users to create an album please follow the steps below.
1) Go to user profile page and click “Media”
2) Click Add Photos
3) Enter Photo Gallery Title in the first field
4) Click Upload or Select from Photo Album to add photos
5) Click Post
6) Once posted, the album will be created as a “Topic” on the albums page for the public to see. The topic title will be the “Photo Gallery Title” they created before uploading their photos.


To create this migration path we used vBulletin5’s default album structure. Unfortunately, it won’t work like the “PhotoPlog” but is an album/gallery component on the forum now.

Dome Installation Video - Casa / Premio / Modena

Hello,

For many of you who bought a modular oven, you may have asked how we put the domes together when we build them. For those of you considering one of our ovens, we shot a video to make your install easier.

Check it out on our You Tube Channel.

https://www.youtube.com/watch?v=-7q7...jSniYogfUra06Q

If the link doesn't work, simply go to You Tube and type Forno Bravo Channel. The video title is How to Set your Forno Bravo Oven Dome Pieces.

Thanks for participating in our Forum. We will have more video content available soon.

  • Dome Calculator

    I was hunting the web for some dome info and found this website Dome Calculators

    Its got some useful bits for those that want to work out the finer points of their designs ! It does a lot of the math for you without the effort. What is good is the 'Level' field, which gives you the dome radius at whatever interval you request.

    It is unit independent, so you can put your calcs in as millimetres, inches, cables or whatever you desire.

    Cheers

    That's a good find. I once tried to find a way to locate the focii of an ellipse, to lay out a flower garden, and lacking a tool like this, I had to estimate by trial and error.

      dmun,
      There's a formula for the foci of an eclipse somewhere. I think I did that in physics a hundred years ago. I found this here:

      Foci of an ellipse - Math Open Reference

      An ellipse is defined in part by the location of the foci. However if you have an ellipse with known major and minor axis lengths, you can find the location of the foci using the formula below where
      F is the distance from each focus to the center (see figure above)
      j is the semi-major axis (major radius)
      n is the semi-minor axis (minor radius)


      Calculator
      In the figure above, drag any of the four orange dots. This will change the length of the major and minor axes. You will see how the foci move and the calculation will change to reflect their new location.

      Almost completely useless information in everyday life, unless your doing a project like yours.

          Re: Dome Calculator

          At any point on an ellipse, the sum of the distances to the two foci will always be the same. You can exploit this to draw one pretty neatly--put stakes at the foci, and attach the two ends of a string to the stakes. The string should have just enough slack that, when pulled tight, the point you're pulling reaches the edge. (i.e. longer string = bigger ellipse) Move the foci farther apart to make it longer and skinnier.

          Then by pulling the string taut in different directions, you can find your outline. Just be careful not to get it wound around the stakes.

          Of course, when the foci move to the same point, the ellipse becomes a circle.
