Lets play... What the heck is RJ up to...
I expect some of you will know right away what this is and what it is for.
So give it a day or so for others to think about it before telling.
I will give you a hint! It is a scale up of a prototype and it does have something to do with blinky flashy!

It's a self winding reel to store all those strands of mini lights. I'll need several when the coop starts ;D :D
Brad

Nice one Brad.
I thought it was going to be something about global thermo nuclear war or whoppers when I read the thread name.
I figured RJ was going to tape cards to it to get that old bike/spoke/card sound going for some part of his show.

Darn Brad! I told you if you knew to wait a day or so before telling! know what am I going to do?
RJ

Does that spin pretty fast? I would guess so. Any problem with the fans staying in sync?
Ron

Beam me up Scotty!
John

Well it has Fans and DC maybe some type of Light warp chamber for Blinky Light you intend on using massive amounts of air flow to create a Northern Light type of effect ? Hmmmmm
-
is it naughty?

looks kind of like the middle part inside the old Martin robo-scan (DJ light - fake laser show)... *could* be naughty ;)

Greetings,,,
Always responsive to the diy lighting community's needs, you've obviously found a way to rotate the controllers in their cases and remove any water through spinning force and the fans, thus solving the problems of moisture build up. This explains all the water tank pics. Those big green things, complete with faucets on the front to water the lawn with the extra water.
Wait, don't tell me. You've also found a refrigeration solution to put around those green water tanks, thus throwing snow out the front assembly!

Laser scanner (one axis)?

Coffee grinder (bottom portion) with laser style status indicator.
Top portion spins and displays time, date, days till next christmas (or easter or halloween or columbus day, next major innovation, etc.... ) on the ceiling and 3 walls. Readable display at 8 to 20,000 feet. (great for that Batman distress signal but that requires small firmware change to downgrade from blinky to just flashy).

I was thinking you would put mirrors on them and direct a couple mr's at them to have a disco party.

Mirrors on slugs? Talk about slow dimming effects...
Keith

I have a hunch that this will be turned on its side when in operation??? And possibly have 16.7 million colors??? Or may be I have no idea what I'm talking about... Probably the latter ;D.

As some of you know and some had good guesses. This is the next stage of Ledtriks II development. I am moving from small scale to full scale proto on it. This device now has four mirrors attached and will be the heart of what I am calling the Ledtriks II Light Engine.
This device replaces between 752 and 1500 + RGB leds for the different configs I have planned. This will make it more cost effective and as you can see a little bit easier than soldering 6000 led connections to a board.
This uses POV projection to allow you to use a few bright LEDS instead of 1000's of lower powered ones.
Projectors like this normally use Laser but lasers and optics to do full color are a way too pricey so I have worked out a way to use LEDS to do it cheaply (I believe) with a few inexpensive optics. The minature protoype showed real promise but I could still run into problems with the large scale as everything like this does not always scale well.
I can't really work on other things cause my computer is running a light show so I decided to work on the mechanical of this project.
The target is $100 - $120 total to build it and I may be able to do it. It will therefore be a little more expensive than the Ledtriks but for full color and higer resolution I think that is pretty cheap.
While it was easy for me to design an RGB version of the Ledtriks using standard methods the amount of work and cost of even 768 cheap RGB leds was too much. This will be able to be done for a 5 to 8 of the cost of that setup and a 100th of the work I would say. What you see here can be assembled by most people is 2 hours or less and will be the hardest part of building it. Ths device if it works out will be twice the resolution and have a controller that does all the work.

Sounds very Cool RJ
So are both box fans power up?
Does one spin in reverse?
It looks like a wood dowel and a alumn square tube. I didn't think the box fans had enough torque but what do I know??
Guessing the leds are pointed at the tube and the reflection is creating the POV
Is it water proof? LOL
When can I beta test it and add it to the wiki :D :D :D

Ok, quiz over now answer my questions LOL :D :D
Nah, Just kidding RJ

Only one box fan powers up. The other is used as a generator to replaced the used power...
One spins in reverse, to create a twist on the tube, like licorice... mmm...
Dowels are unique geometric shapes that don't require torque. See any Wile Coyote cartoon for proof...
Leds don't point. That's impolite. (They smirk and dim when no one's looking)...
It's water proof, depending on how dry the water is...
We're using you for the alpha test, Rick. Stand on a floor fan under a ceiling fan. Hold bot arms out with mirrors on the ends. Put in the wiki when you see the light...

Sorry RJ,
That is a good idea, but it will never work
The workbench is way to neat. Mine does not look that neat right after I clean it.
From my experience, if you can tell what color the bench is the project is not going to work.
Also it does not look like there will be enough wires on it.
You know the more wires the better.
How are we supposed to impress anyone if you make it simple and efficient?
Now a 1000 hand soldered LEDs is impressive.
Maybe you could add some unused wires to it and put some dummy chips on the controllers
-
You forget adding wires is easy take them out and having it still is the tricky part! Believe me I just cleaned find any of the other pictures of my bench and I must of been making something work BIG TIME!!!!!! ;D

I'll vouch for that, I've seen the other pictures :D.

Ok we built the screen and a test setup with a single LED since I am waiting on the order with the rest of them in it.
First understand what you are looking at on the video. The wind is blowning like crazy and you are seeing the ledtriks screen made up of one of my old ledtriks which are 2 ft x 4 ft. The line you see is the Ledtriks Light Engine with a single led generating a line so we can see what the color and brightness will be like. There is no controller to turn the led on or off so it is on continuously causeing a line to be drawn as opposed to pixel dots of a graphic. We also will be dyeing the screen black to increase the contrast even more and make the screen itself invisible.
The color and brightness while it does not show up as well on the camera is good.

Looks nice RJ
Thanks for the update

Cool RJ
You made a blue line
LOL
aka Kmart?
:D :D :D

You do know that I am only messing with ya. I can't wait to have one of my own.

Hi RJ,
I was able to read between the lines and if you are in need of an extra computer, I have one that's been laying around doing nothing for quite some time now that I'm willing to donate to you. It is something I can do for all that you've provided to this community (us mortals).... PC is a Thinkcentre M51 (8104-E2U) small form factor (really cool and handy computer).
Send me a PM with your address if you are willing to accept it.
Keep up with your excellent designs....
-
Wow, that reminds of when I used to have to align our imagesetters here at work. Same principal for projection as the one you are using. We needed lenses to focus the laser beam to a 1/1240 inch dot and the laser was always on with a vibrating (oscillating) mirror in the laser beam path instead of pulsing the laser . The oscillating mirror was close enough to the laser that it didn't require a large movement to direct the beam either on the mirrors or away from them as the path to the polygon was in the order of maybe 3 feet. A rotating front face mirrored (8 sided) polygon spun to provide horizontal imaging and the film was moved under the beam to produce a negative for a newpaper page.
I don't think there were microprocessors back then so it almost all was done with discrete components and ICs.

Thanks but it's OK I had a computer to do stuff on but the computer with all the tools I use was in use as a show computer. I have no time also doing the period that we run shows to do any work like that anyway as it takes what little time I have to work, change burnt out lights, and manage the people at the shows.

Hey RJ,
Any update on the new ledtriks?

RJ,
Just going back and looking at some old stuff, and re-viewed your demo here. How far away from the LED was the projected image you were videoing? What is the maximum projected distance that you are expecting to be able to use with this?
Take your time in answering as I realize you've got a lot going right now.
steve
-
I forget the distance but it is fixed. This is not a projection system if your leading that direction. It is 4 ft by 8 foot screen and I think the depth is in the ball park of 18 inches. Think DLP TV instead of a projector.
RJ
-
Thanks,
Projection was in fact what was sticking in my mind, for some reason. I see where you're going with this now.
steve
-
Just wondering if there was any new progress?
-
Nothing I would speak about.
RJ

RJ,
Since you aren't the least bit busy (yeah right) these days, thought I'd ask.
Any new developments on the Lynx Jumbotron?
Wife says I should just get a Jumbotron for the front yard and be done with it. Since I haven't hit the lotto and its a sure bet Ed Mcmahon or the prize patrol won't be visiting to deliver a giant check thought I would give this thread a jiggle. ;D
Greg
-
No work has been done on it since the last post. I was given prioties by the members of the board and the wireless went ahead of it. Now finishing the Conductor is before it. So sometime next year I should be able to get back to it.
RJ
-
...and its a sure bet Ed Mcmahon or the prize patrol won't be visiting to deliver a giant check...
Ed McMahon's delivering checks only beyond the Pearly Gates these days Greg, so unless you're planning on departing this universe anytime soon... yeah, it's a sure bet ;-)

John
John,
My point exactly! I'm planning on staying here awhile longer as I'm still working on my first universe if you get my drift. :)
RJ,
Thanks. I thought that to be the case, its just the wife's Jumbotron comment prompted my asking. I wouldn't have time to mess with it this year if it was sitting on my doorstep right now anyway. So its something else to look forward to in the future!!!
Greg

I know RJ has enough on his plate, but is there any news the Ledtriks II?
-
Nope, not yet!
RJ
-
Ok went looking around and found some stuff on LED triks. Knowning RJ cant leave his designs alone and always looks for improvement, I was not amazed to find this. Have been interested in doing a LED sign and an updated design sounds good.
RJ I know as always you have plenty on your plate. With the wireless and Aether now done (congrats on job well done), where does this stand on the mix for development? Next year with the conductor?
Any updates would be appreciated and thanks in advance. ;D
-
I have no additional info to give on it. Sorry <yk..
