the driver is a simple audio amplifier. yes, the dac works with the old 25 pin printer port. you better stop thinking of building these galvos because there are cheap china galvos wich are working much better.
so it will be 6k per minute.what did you make drivers of? any TDA or other amplifiers?do you use old printer port?problem is i have new PC and usb to printer port will not work
the galvos are open loop. there is no position detection. on popelscan with a parallelport dac the speed is about 100pps.
hi,nice and simple job.what is aproximately speed of galvos,better than step motors?are they close loop?have you installed any additional position sensors?
Outstanding work on your project! 5 STARS*****
Never mind. I guess you’re the expert…
don’t be a jerk, don’t try and get him to change the name when you don’t even know what you’re talking about. Scanner means an xy projector.
Ach du Schande…
Da bin ich mit der Taste durcheinandergekommen…
NATÜRLICH meine ich 450nm (458 um genau zu sein)
450nm sind so weit ich weiß kein Laserlicht.
445 sind Diodenlaser.
450nm sichtbares rot ?? NEIN !!!!
in DVD Brennern sind 658nm Dioden(=rot), in CD Brennern 780nm (=IR) und in bluray Laufwerken 405nm (=blau/violett)
450nm bekommt man vlt. mit einem Argon-Ionen-Laser hin aber nicht mit einem Diodenlaser !!!!
Nein geht es nicht.
In CD-Laufwerken sind IR-Laser drin.
In DVD-Brennern hingegen welche mit 450nm, also sichtbar rot
sehe hier grade viele videos wo lader aus dvd brenner umgabeut werden, geht das auch mit normale cd laufwerke?
@FesixGermany: Naja schaut iwie etwas merkwürdig aus dein ergebnis. Für den Anfang sicherlich nich übel aber ausbaufähig ^^
Ziel eines Scannes ists ja Objekte darstellen zu können oder halt jede beliebige XY Position anzufahren.
lol guys
If you dont know what about you are talking about shut up.
Laser “Projectors” are called Laser Scanners. It has nothing to do with scanning objects. They scan the sound level / frequency and represent this in a laser scene.
But a synonym for laser galvo is laser scanner and not laser projector
You’re not scanning any objects. You’re just “projecting” the laser hence the request for the name change.
Why??
you emitt lazer. you don’t resive lazer.
Huh?
What do you mean?
it’s not a lazer scanner! it’s a lazer projektor!
nice, my is the same, a have question, what is this song
yes, thank you ..
Hello
On 0:55 it’s a Neodymium Magnet (5mm in diameter) with two pieces of 2mm steel shaft. The shaft will be put between these two pieces and a 2nd magnet will be put on it ( 1:02 / 1:05 ).
Outside of the Galvo is a 3rd magnet. It’s a torsion magnet so the shaft turns at it’s start position.
I hope, I can help you.
i’ll try to build one but i have 2 questions ..
what’s that at 0:55 .. is an magnet or just “iron cap” .. and what is at the 1:15 on the outside of the galvo .. same thing as the first .. or ..
In fact, it’s fast
I was telling belgvr motors wouldn’t do the trick, while a homebuilt galvanometer like this would.
Clever idea to solder PCB material for assembly!
I built a spyrograph laser beam with 2 dc motors, will have to switch to galvanometers some day, and will try the way you did, if I have time…
This is a galvanometer
