Thanks for the tip. I had seen a few laser devices with a rotating three sided mirror and it does indeed improve the resolution. I didn't have three mirrors at the time so I just made due with the single. Maybe I'll improve on the design and make a three sided one. I plan on taking a a version of this to Maker Faire NC this summer. :)
The green laser part of this is very non linear on the leading and lagging part of the display as shown on your grid markings. A double sided or 2 mirrors back to back would also make for a more continuous display. This is a very entertaining use of hacking though.
Nice job Dino, that for the year of cool hacks. For those who want to continue with the laser scope idea, adding a second axis would allow the creation of Lissajous figures.
Thanks for a great year of videos! Not easy to do so consistently for a year! Even with a couple moves in between! Thank you!
Genius man , big respect to your enthusiasm.
This project definitely rocks. One of the best projects I've seen on the UA-cam. Gratz.
You are very skilled!
I would have never thought something like this could work!
Very good job!
I think someday soon i might try and do this.
But part's in australia are a bit more expensive...Just have to make sure i do it right the first time!
Thankyou for sharing!
Excellent work!
Congratulations and thank you for a year of fun and education! I'm looking forward to your future videos!
pretty nice idea you have there... never would have thought of that!
That is absolutely wonderful.
NOOO! DONT GIVE UP THE HACK EVERY WEEK, ITS WHAT DRIVES CREATIVITY
congrats on the full year of hacks. I enjoyed it!
Seriously impressive hack. Determination. I got a different view of an oscilloscope, "graph" as you put it. Cat adds a nice touch as a comedy side show ;) I hope you continue your efforts. Thanks!
Cool over-techie solution. What would have been over the top would be a Lissajous wave form. I've thought of doing that with old speakers and a pivoted laser. I'd like to try it with normal stereo music and with sufferance signals.
congrats on #52, you should put a piece of photo paper or film and expose it with the oscillograph, it would probably come out as a picture of the wave but who knows maybe something else would show up after developing, after all you would be left with a cool photo
very nice. didnt think of using a hard drive like that. so cool. well done
You've effectively done in mechanical means what an oscilloscope does by electronics means. Pretty cool!
Congrats on a full year of hacks. How can you not have a torx screwdriver set when doing so much electronics? I find it more common than phillips on consumer devices.
LOVE YOUR HACK# 52 MAN NICE
Be careful or you'll void the warranty on that hard disk.
Ludemann Engineering Guess his mom never told him the "for want of a nail" ditty... You know; For want of a nail, the horse shoe was lost. For want of a shoe, the horse was lost. For want of a horse the ridder was lost. And for loss of the ridder the battle was lost. For loss of the battle the war was lost. For loss of the war, a nation was lost... All from the loss of a nail. Moral: if you need a torx, for crying out loud, get a set!
Geeze, 4his is from 2012.
Very cool. 👍👍👍👍👍
it would be an interesting experiment to use back to back mirrors, or even a section of one of the HDD platters.
Congrats on your two year aniversary.
or just shine it on a spinning platter doing the same RPM and the amount of time it takes the lazer trail to got from point A to point B would be such a cool effect.
A prism may be a good alternative to the spinning mirror. I like the previouse comment about making a guitar pickup from an armiture. Good option for pickups on a uke.
you make electronics easier to understand
Thanks Dino, this year project has really been great. Look forward to what ever is next.
Enjoy the vaca bro. Peace.
To eliminate flicker, you should have used a mirror that reflects on both sides
The hard drive actuator actually integrates the coil signal, the centering you get is thanks to the springiness of the flat flex cable. It would be better to take a small speaker and connect its membrane to a small pivoting mirror. And do the same thing to the time-base mirror, only either feed it some sawtooth signal, or use those oscilloscope music pieces available on YT.
Well know i have seen everything. (until the next amazing thing comes about ) absolute genius . I used to take a small mirror and attach it to the center of a large speaker , point light at it , now i would use a laser . than watch the reflection when the speaker would move a different pattern according to the sound . Prehistoric compared to what you have done here . enjoy watching your videos ( this one tops at #1) . thanks
I know that it is 3 years ... NICE anyway! What is between the sound output, from your laptop, and the old Hard Drive "head mover" gizmo? The sound would not generate enough power to move the "head mover gizmo" (HMG from now on) - I assume.
I was gonna make something similar and I saw your idea... What can I do to amplify the audio to Voltage, so I can do something like you did here? Thanks in an advance.
I always enjoy watching, but we all need to break loose!
Always amaze me the creativity and brillinat minds......thanx i will try it for sure!
this project was really neat. you rock buddy, so does your cat!
Okay, now I have retrieved the hard drive from my room mates computer but it don't have one of those arm thingies, just a bunch of chips.
send that HD out for warranty repair. Post their reaction here for a good laugh.
Seriously though, great hack.
Because the current going through the coil only exerts a force on the pointer and the dot of light only represents its position, you are actually measuring the second integral of your wave form, which is why it looks so different from what you are feeding into it! :-)
Congrats on making videos for a year :) I hope you have a nice holiday.
Imagine using the motor in the hard drive to spin mirrors made out of platters. Moreover, since the platter can be bent it may be possible to reshape the platter mirror to fit the screen, making the laser point moves at constant speed on the screen.
its genius! going to do it by myself. thanks
Congratulations on #52 Dino!
if you put tiny mirror on the arm and shine laser on that double amplitude. two mirrors can increase it even more.
Really impressive... We can use Convex spinning mirror instead of flat spinning mirror... This will generate full complete signal in box regarding Graticules and the area out of greticules...
I will make one with the stepper motor on the y - axis to replace that HDD motor with the stepper motor for Higher ressolution also like some one here said that we shoukd using the speed control motor yeah good deal .And i do love your project .
Very good hack now u can start on a mechanical television.
you could mount the mirror right above the HDD arm pivoting point to reduce the inertion.
I just love your video's and the way you present them. It is a very big motivation for me to do something too.... :-) thank you very much, and please dont stop....:-)
Dino! I enjoyed watching your videos! Please come back after your much needed vacation! I'll remember to click on your ads!!
I kinda want to know what song you used to test the linear actuator movement, sounds awesome. I would have like to see a square wave as well.
I find E6000 adhesive does a very good job for stuff like this.
If you could suspend a piece of silver mylar between 2 coils and put a charge on it, you might be able to display triangles with sharper corners.
Do you know the old trick of bouncing the laser off mirror strips on 2 speakers?
so nice .. i love it and will try it one day
i find the use of a hacksaw or a dremel to get past the screws before i had a nice set of bits
Can you please point out a little closer which pins go to the voice coil? Thanks
What its maximum frequency perhaps it will not run faster than 50 hz
because of inertia
Really neat project Dino!
Unrelated, but those hard drive disks make great shaving mirrors.
You could mount two mirrors back to back this would decrease the blinking
thatnk you for this. i understnd this a little more now
i picked up some precision torx bits from harbor freight. pretty cheap, but they work. pretty sure t6 is one of them
that is the perfect use for a IBM deathstar. They arent good at staying functional, but they are good at crashing and losing your data.
Awesome hack
Let me be the FIRST to say SECOND! Wooohooo can't believe this has been a whole year man! Congrats on persevering through it all... EGG recipes and all it's been a wild ride. What's next man???
I remember trying to do this as a kid by placing mirror shards on loudspeakers, cannot remember how did that turn out though, never finished it, likely.
Love your videos ,well done.
keep doing videos, i like you format, keep it real.
+HackaweekTV that is great and I have been looking into this for a home sound laser diy project for my home cinema when I came across a video of a different technique months ago on youtube.
I've tried a laser shining on mirrors or CD discs angled around my home to see if the sound wave or sine wave would propagate excite the laser beam into an actual wave, with some disappointing results and my cat Sooty being curious had misaligned the beam in one room by placing his paw on the disc each time that was balanced on some timber wood the disc CD was tided to the wood with a few more discs CD placed around in hallway kitchen and bedroom to reflect the beam so I could hopeful looking for standing waves, peaks and nulls.
While beam was in one room living room while wearing red filter and few hours to set the disc CD up and align as its not easy.
I can use the sound generator/s ether TrueRTA level 2 or REW room EQ Wizard to use sine wave tones.
The beam misaligned and reflected off kitchen taps and few items on my rack shelve in the bedroom and possible over to bookshelf shined off the DVD bluray cases and onto the window more less around same time and embarrassingly a helicopter noticed the beam, where I have apologized for mishap and have since fitted curtains so it doesn't happen again with some fury paws curiosity cat playing with it while I'm in another room. I hope its not as serious has thankfully no harm was cursed but it was something I have overlooked but when doing laser sound diy projects indoors make sure windows a
e covered!
Never aim laser at your eyes always wear a red filter glass (that I have) never shine at anyone else eyes or animals/pets cats do like chasing after the beam for fun that's okay. If setting up arrays of mirrors kece the flicker effect ep curious cats away they may try to misaligned, it and you have to realign all over again.
The purpose for the sound test I think you have shown me the way as its been eluding me for months how to get this idea to work? I knew it had to be possible just didn't know how s its first time I tried this and want to use a different approach over using microphones for picking you sine wave or pink noise tones.
The flicker of the sine wave of the Laser Oscillograph, maybe due to the routing mirror cursing a sort of strobe effect? Maybe if the speed of routing was increased it would reduce the flicker effect, but I'm not knocking your project it gets 100% from me thumbs up. :)
Great video thou some may find it hard to understand I found it relativity easy to understand the challenges and difficulties. Happy laser projects.
Standing in this guy's garage with him, his oscillograph will mostly appear to be fairly solid/continuous. Much cooler in person than seen on video.
The flicker we see in this video is due to the frame rates of recording and playback, and as well, to our persistence of vision. Physics geniuses should know these things already - js..
This made my day A cat named J-FET much funnier that a cat named Buster.
Pick up a fog machine and move the box out of the way, takes away the science aspect and makes it into a rave mechanic. You can see the waves pretty well especially if you increase the rotating mirror speed. :D
did the camera have a dead pixel before you shined a laser in it?
that's amazingly clever
Not sure if anyone cares but if you're stoned like me during the covid times then you can watch all of the new movies on instaflixxer. Been watching with my brother recently xD
@Thiago Francisco Definitely, I have been using instaflixxer for months myself :D
variable speed mirror and amplitude (volume) to laser and something to keep incident light from rear of viewer would be next step maybe.
nice video.. it is a tumbs up for me!
Very clever!
Is the amplifier necessary to run the hardrive? Will the audio output alone be enough to make the tip move?
I would imagine the standard audio output should be sufficient . Lm386's are a 1 watt amplifier so there shouldnt be too much difference
cool project!
It would be nice to see what a Voice Recording of someone talking without any music behind it.
if you see evenly spaced bumps, that is a good sine!
Great video! Drive the laser with some Led Zeppelin, a little modulating with Black Sabbath, you get the idea lol Seriously though, neat hack. I like the green laser too.
doesnt looking at the laser trace directly harm your eyes?
use a multimeter to find the leads . Look for the continuity.
Awsome... But one question how to use this oscillator independently without laptop..
Another tip is to use a older harddrive, sata drives are a little more expensive...
That my friend is pretty cool !!
Hi there,
I came across your video and would try to replicate it to use it as a cheap laser galvos, anyway I was wondering as its not really clear does the motor uses positive/negative voltage only? Can it be directly connected to an audio output? And why is the amp used in this case, to up the voltage?
Thanks
best way to remove screws
a couple of years ago i made me a guitar"pickup" out of one of those linear actuators :D
thanks for keep on making these great videos!
Now that's cool!
Very, very cool.
pretty cool
very cool I gotta make one.
you nail it . awesome
Really cool
Also, don't shine lasers AT YOUR CAMERA.
nimoy007 its a 5 mw so i doubt it would cause damage
What is the band and music in the begin of the vídeo?
What was the belt driven device you used for the rotating mirror? Others mentioned using the ball bearing (rotating) motor from the HDD. Would you or anyone else out there care to elaborate more on how to do this exactly. I thought it was a stepper motor and you'd need the driver module\device to control the motion.
+Tim Thomas It is a stepper motor, google it.
I dont think you read my comment completely, or the way I worded it was confusing. I know what a stepper motor is. There are two questions I inquired about, first being; What the belt driven device was he used for rotating mirror (looked like a VCR assembly?) and the second question was; How to use a stepper motor from a HDD without having a driver device to control rotation and speed?
You can control the stepper motor with a stepper motor controller which you can buy. Google for more details, BUT if you're asking how to run it without any controller at all, then you can't. You can make a controller but it is tricky and it's much easier and cheaper to just buy a controller chip.
+Keenan Smith Thanks for the reply, much appreciated!
@@tmtseverewxchaser I seriously doubt it's a stepper motor, as it would overcomplicate things drastically and unnecessarily. Much more likely to be a simple brushed DC motor like you'd find in practically every kind of disk drive ever made. Easy to find, and no driver circuitry required - apply a voltage and it spins..
10 years later you need to put electrobooms face on that
Very nice
I Just Subscribe & Liked This Video Before Watching It......Just By Readind The Comments, Its so Good...
why not use a mirror on top of a second harddrive actuator?
Nice cat!!
the spinning mirror motor.
... a stepper from a printer?
looks moore like from a tape mashine
