New(ish) LVP ILDA breakout board

[dave]

Thought you guys might be interested to see a board we have been using in our own projectors for a while now.

Features:

DMX control of x and y flip
DMX control of R, G and B level
DMX control of scan thru grating
A clever way of daisy chaining interlocks for multiple projectors
And a few more features including color over ride buttons for alignment, and rear flip switches..


Anyway, it allows us to do stuff like this head chasing

Just tidying up the second revision of this board with even more features.. Would there be any interest around here?

Hi Dave,

I'm diggin it! I really like the fast movement from one projector to another. Great show creation you've done there.

This gets me excited about using multiple projectors, which you would think is a no brained but so often multi setups just look a mess.

Nice looking boards!

I'm interested!

DMX control of things like X & Y flip would be awesome! I often thought of doing that via a DMX relay board and a pair of DPDT relays but never got around to it...

as far as daisy chaining interlocks, been doing that, just copied the way my Mobolazers did it

if the boards are reasonable I would definitely bite

I couldn't use it for my colors since I use 4 color channels in one projector and 5 in the other

I'm interested!

me too!!!!

me too!!!!

[megaton]

WOW!

Awesome

Tell me more.

Cheers,

PS What is LVP?

[LaNeK779]

Lumina Visual Productions??? (just a "wild" guess)

[flecom]

is it going to come with that snazzy back panel with the DB25/XLR holes?

[megaton]

Yes you got it

I see a board from Dave (for controlling servos from a DMX)
And has printed WWW.luminavp.com.au
I enter and yes it is Lumina Visual Producions

Thanks,
Ed

[dave]

Yeah, LVP is for - Lumina Visual Productions.


At this point I am just tidying up the second revision of the board, and adding a few extra features. I think a extra colour channel wouldn't be such a bad idea. I should be able to order some extra recessed panels with the next run of boxes we do Price wise, I think we can make the total price pretty attractive

[catalanjo]

Depends on the "pretty attractive" price ! .....LOL.... thinking2.gif

Very interested Dave. I have three DMX output over my ethernet laser controller, this should be a nice way to use them

[Badpip]

Depending on price, I might be interested as well.

Suggestion:
Since you have control over all the color-signals, maybe a scanfail could be implemented?

[andy_con]

flipping the x and y by dmx could someone explain?

[taggalucci]

Inverting the image, either in the X or Y axis (or both).

Imagine 2 projectors both scanning downwards, flip the Y axis of one and you have one scanning down and the other scanning up. Both potentially from the same DAC.

Doing this by DMX means you'd have control of the axis flips from software like LivePRO instead of having to flip a DPDT switch on the back of the projector.

[andy_con]

i understand what it does. its the dmx bit that confuses me.
is it just a switch on the back of the projector?

[taggalucci]

Just updated my explanation to include DMX

[Stuka]

Count me interested!!

are you asking what DMX is??? DMX is a serial protocol used for controlling lighting, moving heads, fog machines, strobes etc etc

if you are asking why you would want to the reason is simple, you can invert your X or Y while your projector is up in a truss or something during a show to create neat effects if your running satellites off of one DAC for example

Hows the progress going Dave?

I'd be up for 4 of these depending on price. Keep up the good work.

I would like to comment on the feature of controlling projection brightness through DMX:

Take care to only allow reduction of the projector's brightness through DMX. If you don't, you might mess up the Beam Attenuation Maps set in your DAC and even cause accidental laser emission by your lighting tech when your DAC isn't outputting a sensible signal.

If you scale the R/G/B brightness by a factor controlled by DMX (255 = full DAC brightness, 0 = off), you should have no problem. As long as the DMX brightness doesn't override the DAC's brightness signal.

Edit: You may even be able to scale X and Y in a similar manner through a set of DCA's, and allow arbitrary scaling of X and Y over DMX. In that case, make sure to clamp the value to a sensible lower boundary, because X and Y scaling of zero would result in a static beam.

I just sent off revision 2 of this board So not too much longer I hope

Hows the progress going Dave?

[neutrino]

Sweet, can't wait. ANy idea on pricing yet?

Cheers

[dave]

Just a quick note,

I have the boards for these. Will order parts first thing next week.. Something is happening at last

Awesome news. Keep up the good work.

Just finished testing the first board, and so far so good Much happier with the second revision, just gotta add a couple of things that I never got around to with the original, and then its disco!
