Simple laser spirograph

[Sophiafording]

Cool thanks man

[FelipeZucchetti]

nice

[JSprayaEntertainment]

im trying to make a 360 spirograph can you make a video please ?

[alec11116]

try cutting up a cd and using that for a mirror

its awesome

[Archididascalian]

@thepoetryplot Gives it a 3D effect. And unlimited patterns. Very cool.

[julianna891]

cant yu make a lazer show with speakerss and a mirror???

[marzatomika]

what do u use to reverse the motor?

[Glassblower718]

thanks, and good job !!!

[999skilit]

looks cool wow :o

[GeneralSquirtle]

nice dood.

[zzsseeffvv]

I tried doing this at home, but it didn't work. I think its because my motors go too fast. Do you know how fast they are supposed to go?

[studistudi]

Ive finished my own yesterday, and it doesnt matter how fast the motors go.

Both mirrors should be slightly angled and the reflected beam should be reflected on the second turning mirror and thats it

[GregMcMahan]

I used to do fun things with a laser in the mid 80's. One of my favorites was to attach a very small piece of a mirror to the inside of a speaker cone and turn on the music. Or use a large bass speaker, turn it so the cone is facing up, and place a shallow pan of water on top. Lay a small mirror in the water, turn on the music, and bounce the laser off the mirror.

[daxweb]

great

[EcasmbNoobje]

Waaw how you make that do you have tut video ?

[mackintoshnessly]

ive made one with three mirrors and motors with an automatic mode

[tannermann]

1:47 INFINITY WARD HAHA!!!

[pokejuice]

How much mW is the laser pointer?

[Ravenpulse]

thats trippy

[littlescale]

Excellent work!

[RustyNex]

wow thats actually awesome, i was expecting it to be kinda crap but it worked out really well

are the mirrors at slight angles on the gears or are they flat?

[buzbee1]

Yes, the mirrors are at slight angles - I forgot to mention that in the video. I didn't have to do anything special to accomplish that. I attached the mirrors using double-sided tape mounting squares (about 1/16 in thick), and it was irregular enough to give me all the angle I needed. One other easy enhancement would be to use a 3rd mirror attached to a speaker cone. Play some music and watch it go.

[RustyNex]

ah cool thanks for that! I am going to give this a try as i have some blue green and red laser pens to play with, as well as some lens adaptors that make lines etc, could be interesting.

i love the idea of the speaker mirror too, i have to give that a go!

keep up the great work

[Coby19666]

Sweet :o So that's how laser shows work :o

[magic101magic]

do u make a circut board or just hook the potentiometers on

[HowToHacks90]

"This will look like the Adobe logo."

That made me laugh. It's very cool. You have my subscription.

[Ahnaf]

how do you control the speed of the motors spinning? what do you use?

[hippiesal]

to change the speed of a motor, you need only change the power its recieving; the more power, the faster itll go.

[tony70516]

no your wrong, its called a potentiometer you hoook it up to the battery and it regulates how much voltage goes to the motor

[me2910]

If that's true, tony, then hippie was right.. you just said he was wrong then said exactly what he said but went into specifics..

[tony70516]

yea but i replied to the question what do you use to change the speed.. hippie didnt answer that question, so i did

[cbrian4]

What range of ohms is the potentiometer 25, 300?

[elgranto7]

I'm gonna make one over the weekend =]

[jnaproductions]

Thanks for that!

I just have one question, as I am doing this for an electricity project at school. When both the mirrors spin, it still makes a circle. Have I done something wrong or do the mirrors need to be at different speeds?

I will highly appreciate it if you can reply buzbee1!

Thanks - Jna

[buzbee1]

An important thing I didn't mention in the video is that the mirrors must be slightly off-perpendicular to the motor shafts. I used double-sided foam tape to attach them, and the natural variation in the tape was enough. If you're gluing the mirrors, just make a shim out of folded over paper and jam it under one edge of the mirror to give it a slight angle.

[buzbee1]

The laser pointer I'm using here is < 5mW, not 50 mW. Even so, I wouldn't stare directly into the beam. When dealing with lasers - even relatively weak ones - remember the warning poster: "Don't look directly into the beam with remaining eye".

[Naurtopokemonmaster1]

my 5mw laser is not that bright and green same thing as your

[chinnerz2]

i have a question, are your motors spinning the same direction? what difference would it make if they are/arnt?

[mikeeey1337]

awesome! I've been wanting to make these for a while, and tomorrow I finally will. However, I cant understand how the spinning mirror make's the actual dot move, i mean, if the laser is hitting both mirrors in the exact same spot but the mirror itself is moving, I dont see how that moves the dot. Unless the mirror was glued on at a slight angle! ahh! i need to see it in person to understand, is there anyway you could explain this?

[buzbee1]

Yes, the mirrors must be attached with a slight angle. I used Scotch Mounting Squares, which are like double-sided tape, only on a thin foam base, and there was enough natural variation that I didn't need to do anything else to get the offset.

[sampenso08]

i saw a similar video but the guy used three mirrors. this allowed for 3D images to be projected onto the back drop. im thinking of making one with three mirrors over the holidays. if i ever do i will post a video and instructions as to how to make it.

[SistaQ10050]

O.O

WHERE IS THIS VIDEO!

I'd appreciate it plz!

Thnx ^-^

[jamus618]

THe reason your motors are reluctant to keep spinning at slow speed is because slowing them down with potentiometers is not the correct way to do it. You need a pulse width modulation circuit, so that the voltage is constant but it switches on and off very rapidly.

[deckoland]

i need to find some varieble resisters hat i can wire up and can with stand 3 volts where could i get them from aprart from scalectricks and traintrack controler

[lamborgini8]

Hey mate, where did you get your mirrors? Or if you have any spares can I buy some?

[chunkyyluvr5]

how powerful is your laser

[macmacron]

thats cool
