DIY Laser Show: The Model of the Atom

@Starcross42

I have done everything, but just can't get the motors to run at the same speed. How do you make them run at the same speed and opposite directions?

[Starcross42]

@drumerkid1014 Opposite directions is easy. Reverse the polarity of the wires to one of the motors. Speed is a little tricky. Try putting a small variable resistor in line with one of them...Good luck.

[drumerkid1014]

@Starcross42

How do you get the motors to spin at the same speed? I have everything done, I just. Ant get them to run at the same speed.

[drumerkid1014]

@Starcross42

Sorry, this is very important, please answer ASAP. Did you use dual axis diffraction gratings on both of the motors? Or dual on one and linear on the other?

[Starcross42]

@drumerkid1014 First, I always answer ASAP, so you don't need to keep asking.

And yes, 2 axis gratings on both motors. You can get the gratings at my web site.

[drumerkid1014]

@Starcross42

I didn't think you would want that much, I'm going to try to make it myself. Thanks again.

[drumerkid1014]

@Starcross42

Just wanted to clarify, I meant the entire thing.

[drumerkid1014]

@Starcross42

Could I possibly buy this off of you?

[Starcross42]

@drumerkid1014 I happen to have an extyra one that I made just sitting around. $75. Still interested?

You can order the diffraction grating from my web site using paypal, and any Radio Shack will have the motors. But if you still want me to make it for you then go to my web site and make a paypal payment for diffraction gratings, and when you get the option of $6 just change that to $75. It can be in the mail this week.

@Starcross42

What size DC Motors did you use? Please answer ASAP!!!

[Starcross42]

@drumerkid1014 These are small DC motors that start at about 3V and max at 6V

whats that like electronic purple thing on the left of the frame

it looks pretty cool

[djteac]

I'm so glad that i'm not the only person using Legos for Laser effects.

I even use the to gear down motors.

I geared a 15RPM motor down to 1 rpm every 2 minutes. Amazing to use for some real slow and chilling grating effects.

And Legos are just cool.

Hello friend...

which sheet is better for laser purposes?

the 13500 - 1000 or 500 lines per inch?

Thank you very much.

[Starcross42]

@ChicoDaRave Try them both... However this one has the lower diffraction pattern.

[ChicoDaRave]

@Starcross42 Thank you very much!

[Bowtie41]

Hi,

Is the grating reversible,and if so,what difference in the pattern would occur?Also,what is the rpm of the motors you used?Have you put pots on them to change patterns?Thanks for the great vids,as always!

[SysAdmin86851]

woa ! far out, man ! that's trippy ;)

[18shelly18]

@SysAdmin86851 thats my teacher

[laserpyro]

hey starcross

im on the rainbow symphony site so which gratings do i need is it the 13500lines/inch or 1000line/mm or 500line/mm?

Thanks

[Starcross42]

Two axis with the most lines/inch. The others produce intersting effects (I have them all) but this one is the higher number.

[j8055man]

I want one!

[sgtbakers]

Wow, your very intelligent. I never knew some of that stuff.

[Starcross42]

Well, the physical size doesn't matter. I have cut pieces with a hole punch, put on the laser, and get the same effect. However diffraction gratings have different 'gap spaces' that produce different patterns. Does this help?

[PSPFreak602]

Ya. That answered my question.

[djhydro1]

could i make this laser for club and party???

[Starcross42]

Easy. However it looks better when put on a screen. If you want beams in the air then use one of the other effects. Check out my home page to see "The best laser effect ever".

[PSPFreak602]

Does the size of the diffraction grating affect the laser effect in any way?

[PoPoNellie]

Cool, it reminds me of something you would see in the queen's chamber of a borg cube.

[chemicalBR0]

I wish you were my physics teacher...

he was a boring old fart.

you seem like a lot of fun

[Tstahl13]

Yep He was my physics teacher. Best Teacher EVER!!! made learning fun and taught very well

[salsburyp]

Fantastic. You never fail to amaze! :-)

[tinanancollas]

You are a science genius. I love your videos and you are so cute too. Do you have a Harley? Of course you do! I'd love to go for a ride with you!

[itsabomberscope]

these are very enjoyable, thanks!

[Starcross42]

No, this is a DIFFERENT effect. The other one was slow speed with a wider diffraction gap (more beams) on single plane gratings. And this one has a much better production level. But this is the last of my laser effects, so there will be no more.

[Helioplasma]

To think that you already did that on the other laser show video !! Ah you missed big !
