PIC based laser spirograph

[Guywhownsthisaccount]

Name of song?

[APDigitalLight]

@Guywhownsthisaccount It's my own homemade music.

[RobbieGarv]

hi there just wondering if you could forward me on any other relevant info and the code for this project as i am doin somethin similar for a elec eng project thanks.

@RobbieGarv

See video description.

There's link to my blog where you can find detailed tutorial and code.

A great how to video

[stormovies]

please tell me the song sent it to me

[APDigitalLight]

@stormovies

I've sent you PM with link.

[gulllars]

It would be great if you could hook this thing up to a computer over USB and make preconfigured runs, or have a program analyze music to be illustrated.

[APDigitalLight]

@gulllars

I've designed new version of spirograph with ability to program custom patterns and save them in internal memory with press of a button, then play them in sequence like slide show.

[gulllars]

@APDigitalLight Thanks for the quick response. A device like this could be great if provided with a driver/software layer to enable it to take input from other programs, like music programs. It wouldn't take too much effort to make a database of A,B,C values (x,y,z frequencies) of known geometric figures and fun to watch variations for use with some scaling functions. Provided such a library, you could make a reatively basic program analyzing music and illustrating the melody and rythm.

Hi

very cool project you have there!!! i also want to build a compact spirograph, i've already done a 2-mirror spirograph but without speed control, only touching the mirrors xD.

Which type of potentiometers do you use, with which specifications at which voltage?

that would be helpful to me!

Peace

[APDigitalLight]

For informative answer there's not room in comment.

I sent you PM with specifications.

[destinws2]

Cool music

[loveforever404]

i would love a pm too:)

[APDigitalLight]

PM has been sent.

[rayboy0608]

is there somewhere i can buy that, or can i jus buy yours

[APDigitalLight]

I make spirograph upon request.

I've sent you PM with details.

[edgard409]

could you please send me a pm also I with the details also?

[APDigitalLight]

@APDigitalLight

can u pm me also like the ciruit of the thing and how to reflect the lihts

[APDigitalLight]

PM has been sent.

[ogemperle]

Hallo, could you please send me details also? Thanks

[APDigitalLight]

PM sent.

[MacsCanfly]

@APDigitalLight can ya send me one

[APDigitalLight]

PM sent

[enter642]

This is a really neat project. I do plan on making one of these.

On a side note, What song is playing in the video?

[APDigitalLight]

Thanks for comment.

Background song is my homemade music.

I still have some spare parts and mirrors.

Let me know if you need some.

[EcasmbNoobje]

can i buy one from u?

[APDigitalLight]

I've sent you PM.

[Splooshiba]

im making one as we speak, was going for a 2 motor one but after seeing this am defiantly going for 3

trouble is i only have a blinding 30mw laser :P

[laserpyro]

30mW would be perfect, wont blind you unless you hold in front of your eyes, plus your likely to see the beam aswell

[Splooshiba]

its made now, works a treat, check ma profile

[mihaimcm]

how much was the green laser?

[APDigitalLight]

It was 30$, long time ago.

[marianoaldogaston]

well done, now I must to make one of this.

I will put it in mi "to do" list

[randomlugia]

What's the song called?

[APDigitalLight]

Background sound is result of my fun experiments with FL Studio.

[1800mauler]

i love fl studio :)

[mikeeey1337]

are the mirrors glued on at a slight angle or strait on? I'm asking cuz I'm going to make one and some people have told me to glue it at a slight angle and some have said strait on.

[APDigitalLight]

Mirrors should be tilted at 2-3 degree.

Refer to my tutorial page for more info.

[mikeeey1337]

I have got my spirograph assembled and working, and my mirrors are at a 2-3 degree angle, however I'm only able to get basic designs, not like some I have seen. I was not able to access the 3rd dimention with my 3rd mirror. I was not able to get any of the designs you have showed in your "laser gallery video. another problem I'm having is the "range" of turning with my potentionmeter. I'm using normal sizes 12V CPU fans running the full 12V. 1k pot = worst range, 5k = better, 10k = even better.

[mikeeey1337]

I was told to get 500ohm potentionmeters for a better range, but from what i can see this will make my range worse. again my best range so far is with a 10kohm potentionmeter but even then my range is only 1/4 of the the whole turning range, it's still too sensitive. What type of potentionmeter did you use?

[APDigitalLight]

I use microcontroller to generate PWM signal proportionally to voltage on 10K pot.

My control range 0 - 100%.

[cbrian4]

Are these for sale?

[APDigitalLight]

I can provide electronic components for DIY project or make whole unit for people who is interested

[cbrian4]

How much would one completely assembled cost?

[SeanChaney]

I like your motor mirror layout much more compact than the old way of staggering the mirrors down a bread board. Great job!

[JamesKM1ll]

I want one! :) Very nice.
