LUMIA- one thread for all-

[Pman]

Doesn't it say LED? Think they got it labeled wrong in the title and it's just LEDs

 

[hakzaw1]

Damn I just saw those at Home Depot. I actually stopped my family and said wow these would be great for my lumia . ..... They shrugged and said .......ok

I am guessing you did not- what you saw were bigger or plastic or LED or all three- but not the small glass ones I seek-

Ebay is really pissing me off with their fricken survey-I keep getting it and no matter if I take it or not it keeps turning back up and I hate it.

if we choose to not take it then FeeBay needs to accept that and forget the survey.



I am thinking glass bulbs are really not being mass produced anymore--its all LEDs and plastic--
also FYI C7 is the size of the base and has nothing to do with the length-
both bulbs in my pic are C7=

 

[hakzaw1]

I hope you can find out if those three boxes of Sylvania lights are glass or plastic=glass will NOT be LED and LED will NOT be glass afaik.

if so they may be worth that much = hk

Hak this lumina kit is extremely addicting, thank you for sending it out!! I can't believe how much time I've spent staring at the wall lately though! :crackup: I'm using RGB enjoying hours of endless psychedelic eyecandy, this is just sick man! After reading down only the first page of this thread I see I have several more options thanks to swami & pman amongst others, thank you everyone for your input!

I have to take some pics or a video & share what mine looks like but I think have to slow my motor down. I fully agree with the discussion before about 1/3rd RPM being more enjoyable than 1RPM & right now my motor is around 1RPM. I tried rotating the bottom half of the case a little in both directions but it didn't seem to do anything & I dont want to damage it. I'm sorry if this question was answered before & I missed it but how do I slow the motor down?

:beer:

Len, unfortunately those bulbs were of course plastic (edited my post about them a few days ago).

By the way, I took apart a Gillette Fusion razor and it has a really small reversible 1.5V DC motor in it. On the end is an offset weight to cause the vibration as I expected. Have a couple more of them.

Confused danefex. What motor are you using? Kind of thought Haks kit came with the 1/3 RPM motor.
The effect can be mesmerizing for sure. You should see it on the LK-PD2 projector. It's lots of power and very big.
Hmmmmmm I'm thinkin danefex needs a PD2 or 3D Len That's weird, isn't there a GB going on right now for them?

 

[Tmack]

Hey Len. I wanted to double check how to wire those motors you sent me.

 

[Pman]

Aren't they just the 120V 1/3 RPM ones? Just get a 2 wire power cord and one wire to each leg. If they say AUTOTROL 120V, 2.4W and 1/3RPM then they are the same ones I have and what Len uses.
Also were't you supposed to get another build today? Sorry off-topic but I had to ask.

 

[Tmack]

I got them going!!! And yeah I did. Check the black Zaser review thread

Yes that's the motor I have. I just checked the bottom & noticed the 120V 1/3 RPM markings, clearly I missed that print when I received this :spank: What I did see though was that it was made in Crystal Lake, IL which is 5 mins from where I live. I googled the info to learn more about these motor(s) & came across something like this that showed an adjustable motor speed from 240RPM to 1/32 RPM (something said 'one rotation per month!) Of course I can't find that listing again but I now see the unit I have is set at 1/3RPM.

Needless to say it's still awesome at 1/3RPM, but honestly I could use one at 1/20RPM. The slow morphing from the lasers around that speed would hypnotize me!! I'll have to look around to see if autotrol has anything like that :thinking:

Thanks for helping me figure the speed out Pman! :beer:

 

[Tmack]

I plan to almost gear mine to have two going at different speeds. If you were to use different size "sprockets" you could achieve any speed you like.

 

[SerpantSlayer]

Wow i really like the effects theyre amazing. Still going to stick with portables for the most part though

 

[Tmack]

Why not all of the above portable, lumia, projector . Eating is over rated

OKAY-

AC motors --not as easy to slow down and unlike DC motors not easy to reverse directions (something I have yet to see a need for) also DC motors can be slowed down some by simply using a lower voltage-or you can use gears to alter the RPM AND as the flat LUMIA glass turns 'faster' as you go farther from the center-you get slower 'morphing' that way-- For good still pics don't power the motor(s)- for good vids you must-

One of my first Lumia PJs had four motors (all 1/3rd AC) and six lasers inside- with three hitting the wheels where they overlap-- an interesting efx BUT adding many more 'layers' to scan thru does not always make for better LUMIA-

One of the ways to see the less powerful colors is to use the lowest power green you can find- one good one (pricey now but cheaper in the future) is the $85 515nm complete module from AixiZ- at 26mW is PLENTY- with more your other colors will not show well- another way to lower the power of any green is to use a wave plate that splits the beams into two and thus each will have one half the power- use a 'turning' mirror or two and 'redirect' the beams.

I had a nice chat with AixiZ owner Dr Chuck Maricle concerning the RG 'twinkle' lasers He tells me that so many have been made that it has become a buyers market -demonstrated by the fact that you can get one of these at Ebay (use a snipper btw) for around 20$- most have about 20 -30 mW od 532 AND ~100mW of 650 red-

Thats crazy cheap- impossible to beat or build for less- I was given a free one that was returned to AixiZ- (a wire to the motor had come loose) so I completely removed the two lasers and the rotating diffraction grating(s)- so whats left is a nifty two color mini 'labby' complete with switch- sound response, heatsink, PS and in some, a small fan- the two beams are about once inch apart- the circuit board makes these go on and off randomally- which is fine by me but I bet you could work around that--if desired.

Another interesting and low cost idea is to use 4$ pointers- use only the front- power it(them) by a wall wart- add some kind of additional heatsinking and switches that allow you to 'play' to the music and also turn them on and off using a rest/duty cycle to avoid killing them- BUt if you do- its only a 4$ loss- these allow for a very small Lumia PJ and you could use just one 532 but many more reds and 405s-

remember- its easy to have to much green(or 445) and no such thing as too much red or 405-- the heatsinks could be made in a fashion that also holds down the button for you- adding a fan or two might also allow less rest and more duty-

Enclosures for LUMIA are, for me, easy to find-
as for the base plates-- warping is nothing we deal with- so almost any material will work- -at 1/4 th inch-- Al, 'thawing' plates are nice- easy to drill and if too big for your chosen enclosure not all that hard to cut down-

the white plastic cutting boards are also very eazy- & simple to cut down to size and a small hole needs no threads--just a bigger screw- I found some hardboard shelves with 1 inch center holes much like a $$$ Newport optic table- except white- (now painted flat black)

I found some at a thrift shop and cut them down to several smaller ones- these had Al fronts and backs and once sprayed flat black no longer look like shelving-
So you can use the existing holes with bolt and nut or drill new holes--
You can find similar plastic material in 4x8 foot sheets- but thinner and no Al sides- and less rigid.

One reason I started this thread was to have one place to see info and examples of LUMIA- so maybe posting here and adding pics/vids may be a better idea than starting endless new LUMIA threads- this is what we have done with Ebay and other good deals all in the same thread- IMHO it makes for a neater forum too. OR at least link your new LUMIA thread in this one--

and two ways(of dozens) to attach LUMIA glass to my 1/3rd rpm motors

OK-- Noah has found the source so he gets the free basic kit-
thses are still to 'spendy' but now that i know who makes them I should be able to get them cheaper buying a larger number.
I have been asked why I want smaller versions of the bulbs I found at Lowe's-
I have several sizes of LUMIA PJs working and while the larger faceted bulbs are great for lumia with 2-3 or more lasers I need the smaller version for one or two color Lumia PJs- so no need for a big bulb in those.-

thanks noah- good find and congrats on winning.

BUMP!!!

btw I fully understand those wanting to start new LUMIA threads- thats good but please come to this one too and link us to yours.

the one big thread for ebay (et al) great deals has been swell idea (thanks Aaron!! aka 'allthatwhichis'))- so I was thinking that same idea would be good for Lumia fans. You can find stuff faster by using the 'search this thread' function--

Simple projects like LUMIA are a great way to get those around you to understand why you need more than one laser--
One color lumia= nice -- three color = absolutely awesome...
AND its kinda awesome TOO that LUMIA is nearly 100 years old yet still is popular.

for info on a haklumia kit PM..

First things first. New month so new start of donations

You're most welcome of course danefex. I know, even 1/3RPM seems very fast sometimes depending upon what you are using. I will say that those motors are not "wimpy". They have lots of torque. Am kind of surprised at how warm they get.

My vote is to keep all the Lumia stuff here and if you feel the need then throw up a link. I would much rather prefer we keep throwing out ideas and stuff all in one place rather than have it spread all over the place.

He found those bulbs in Lowes? I almost stopped there yesterday to take a look as Lowes, Walmart, Home Depot, VOA, Salvation army, Goodwill, Harbor Freight etc... are all within a 1/2 mile of each other where I live (and only about 15 minutes from my house).
Are you absolutely sure they are glass and not plastic? I saw plenty that looked right at Walmart but were plastic. Every Christmas string of bulbs I saw were plastic and there weren't any glass bulbs that were right and I really looked.
Is there a skew number or anything? Hope you don't have to buy a 50' string of them. I am confused whether he found the smaller ones or the bigger ones.

I still say you guys should mess with that GITD spray paint when using a 405nm. It's only $5 a can so why not. Everyone I've shown my GITD screen to has had lots of fun "405ing it"

"haklumia" is the sound a Len makes when it sneezes.

Hate to admit it but I did end up buying those 100 small mirrors from Ebay as I thought they would be OK and that was the last of them as far as I knew and unfortunately I didn't hear back from you in time not to buy them. They are not FS. They are nice little mirrors though. Going to send me some of the right ones to use then Len? lol

Hey, I did find a few things at the Salvation army store Len. 3 auto rewind cameras (took apart and sorted the lenses and motors), An identical dirt devil small hand held vacuum that I allready have but was missing a couple pieces, a few interesting pieces of glassware and a 120V AC to 12V DC 6 amp brick/wall wart all for $11
Ran out of time to really look a couple other stores over.

While I was at Walmart I saw something really interesting too. Check out my post on page 73 of the "Win thread"

Just testing some components. Without knife edging the effect is surprisingly close and overlapping
