LED Hard Drive Clock Demo
Вставка
- Опубліковано 8 вер 2024
- This is a hard drive clock I built from a 3.5" hard drive, some tri-color LEDs and a PIC16F252 microcontroller. It works by shining the LEDs underneath a platter with a slot cut into it, and by timing the various colors it can produce an analog clock display as well as other patterns.
I got the idea from this page:
alan-parekh.com...
And here is my page with more details:

I've been an electronic engineer for 41 years and I find it remakable that folk are so innovative and creative with junk what would ordinarily be thrown away.
This is superb. Well done.
@davcnslt that's true. i love when people do this amazing things these old things. cheers!
Clean it up, quiet it down, keep the look, patent it and I will invest in you marketing this product. Pure AWESOME!
That is one amazing clock you got there!! Very colorful!
I think this is a well thought and good learning material for people who want to learn to play around with electronics. Nice work!
If you want to build your own, I advise caution when slowing down the hard drive. Don't slip your finger too far from the center or you might lose your fingertip.
@Surabpachida It no longer functions as a hard drive, it's just art now. Won't be covered.
Having the LEDs mounted to the case instead of on the disc is genius!
As the slot passes over that segment, the LED flashes red for a duration "t." t is easy to calculate because the speed of the wheel is known as is the diameter and slot width. So the color of the LED can change 10 times over period 10t, allowing for each segment to be a different color. Then it's just a matter of programming the controller to flash different patterns.
@macypctutoriales It really isn't about what you can do for your hard drive or vice versa. It is really about a geek with an old hard drive can do with a lot of time on his hands. LOL. I love these little explorations into what can be done with what most of us think of as junk. Very creative.
Thats awesome sept the anti-clockwiseness and the huge amount of energy it's using :D
I am very impressed. You must be one very intelligent and dedicated guy to do that! I have been programming PICs for a while now but find it hard to get my head around just how you did it. Because of the high speed it must "trick" the eyes to a certain extent?
Great job!
That is, without a doubt, one of the coolest things I have seen on youtube, to date!
You are a genius! I'm working on the same project and I know how difficult it is
That's about the coolest clock I ever saw! Great work making it!
the last demo was the coolest
@LegitCustoms Because he's reversing the time space continuum.
this is probably the coolest thing ive seen on youtube, great job
This is too advanced for me at the moment but I have to build one myself when I get a hang of micro-controllers. This is too cool.
This is amazing, brilliant!
the sound of this spinning thing sounds very relaxing for me :)
i've never seen anything like this! i didn't think it would be such a sharp picture, but a 90hz physical refresh like this is apparently VERY VIVID. i'd like to see a 7200rpm drive, i like all these news 120hz displays coming out! ;)
i love this, gotta be the best mod i have seen yet.
That is a very cool project. Nicely done.
I knew what they were, I was asking where they were. I think I see them now, there is nine under the platter.
Very cool project.
That is awesome.
yourtiy, it is loud becuase the slot he cut in it set it off balance. At those speeds, even just a little imbalance will causes it to wobble and be louder.
I want this guy to make me a food processor! Genius!
Wow i got nerdy goosebumps all over. Good job
You are simply wow. great creativity. Please share your knowledge to us.
Regards

@bilkyasko Turning it upside down won't change the direction the hand is moving. You'd need to view it from the other side or a projection against the wall for it to be rotating clockwise.
Regardless, even if a little impractical, it's still very cool.
Wow what a cool way to reuse a bad hard drive! Very nice and creative work :-D
On a second thought, there must be such a sensor already built in the HDD spindle motor and you are just using it. Cool!
If you can get a decent video display on that thing, then you will be the master of them all, and also a very rich person.
@Amaroqdricaldari A drive's head floats 5-10 nanometer above the platters, if dust comes between the header and the platter, the head will crash.
There already is a hard disk with a built in window, Western Digital's Raptor X.
Great concept and really nice handy work. Inspiring.
That thing is gorgeous.
@Juni0ri He doesn't need to make it spin the other way, he just needs to reprogram the lighting of the LEDs
@longbow192 That's correct, 12V for the engine (engine requires more power) and 5V for the circuitry :)
Other than it being rather quick in its definition of a second, this was pretty neat. :)
this is soo cool, im rediculously jealous
Be nice.
It's still a work in progress and I have not finished tweaking the clock part. It's been more fun adding new patterns and trying to mix the colors better than to make the clock actually keep and show the time, especially since it's so loud it only runs for a minute or so at a time anyways.
this is really cool! could you do a tutorial on it?
creative! i love creativity. its contemporary and facinating!
very cool thing! As far as I remember, that's how the first television sets worked :)
Great!! Tinkering like this is pure innovation. I challenge the haters to understand any of this.
pretty cool dude.. am gonna try to build one myself now !
Wow! You could market this as a fancy clock that you can change colors, patterns, etc. It's a little noisy though. That might be a hard obstacle to overcome.
@savikate: it can probably run longer than you think, after all, it is a hard drive, which can run for a good long while...
Good point Pencilman, like some videos of the wheels of cars spin backwards at certain speeds.
That was really cool, made my day. Great work.
Guys, this is cooler than a laser show...I know because I own a large RGB laser projector and this is just too cool.
A gigantic version of this hanging on my office wall (or in a dance club) would be sweet...
@lolcheesecake It's acting as a display, therefore it could(should) be programmed to display the correct movement.
holy crap, how the hell are ppl trashing a video as innocent as this. I think this is so fuckin neat.
Ah. Good job, this is great. Very unique.
wow CONGRAGS ! I would like to build something like that - just the lcd display would be satisfying enough 4 me.
If it is a backwards clock, I love it!
Thats epic! Id buy that watch without doubt
nice work.. i don't understand but it is very colorful and intriguing.
@rastarecords3 the display is backwards cause of his webcam and it tells the time if you're mildly savvy
I must agree, I do want to buy one!
That's really cool, man. Thanks for sharing.
You can get SCSI disks that go at 15,000 rpm too.
For this project, 5400 rpm is fast enough. If it goes too fast I would need to use a much faster processor to keep track of it!
@MKahn84 Just reverse the electric current going through the motor. Then it will go clockwise.
What would be awesome would be an Optical Disk Drive or Hard-Disk with a Motor that could spin in either direction.
Absoloutely amazing.
Well done.
Wow, the colors at the test pattern looking like on PC's CGA video cards =)
@10OchrisO01 ITs not... it is going counter clockwise because ... test filming a driving car... or a fan... it will always go counter clockwise or in the other direction as its really going... it depends on the fps of the camera... you can wiki it. ^^
You have demonstrated everything physically necessary for displaying video. What's Next? I'm hoping for SteamPunk T.V. ***And what can be done with a spinning hologram?*** Very cool project. Cheap parts.
@MTLAccord And the number "12" is at the bottom of the clock !
Wow! Fantasticly beautiful.
Wow that is creativity. i wish i could do that. Awesome work. and funny comments lol
@MTLAccord perfect if you wanted to make a projector clock
what the ... wow - . just wow ! great job!
If you balance the disk (compensate for the slot you cut by adding some weight there), the clock would be a lot less noisy. Nevertheless I think this is a very nice clock :)
@fetymann yes because of the camera. 25 fps revert normally clockwise fast movement.
What a brilliant design from a brilliant person! It's truly one of the most impressive videos on UA-cam!!! Do you play to mass produce this thing and sell it? I will buy one!
@jse07 & @doc842 its dead anyways cause its been touched, the platters have to have perfectly clean surfaces to be able to read and write anything
thats awesome though
Cool little thing you created there. Spencers gifts sold a dancing light wheel simular to that, but yours is better
very good your projec, I really liked..
@masteircheef Sure you can connect it but of course it wont store anything. It's a huge frikkin jack in the plate
This is so sickk,, Wow,,, great example of geniusnesss!!!
@buvamozilla Sony Vegas is not a special effects program it is designed for basic story board editing.
After Effects is used by millions in hollywood and other major movie hubs. But even then, this isn't fake.
Dude this is awesome, you should make tutorials on how to make this.
ME WANTEEE 5/5
Gentleman... Theres the final piece that the Delorean from "Back to the Future" uses as a time controller behind Flux Compacitor and Mister Fusion!
Hi! I checked your webpage and it seems to be an error in the schematic! The VDD and VSS of the PIC are going both to the ground..
check that!
Very good project!!!! And amazing result!!
i bet you had fun making this.
That's pretty awesome. good job.
Run a patent because Im a buyer for sure. nice. Just keep a few variables for play on a few variable resistor knobs.

02:13 Looks like a chrome logo!
This might seem cheezy, but he should find a way to grind off an equal amount of the underside of the platter opposite his grove, to counterbalance it (save the bearing), and perhaps paint the underside black to absorb reflections.
that thing is really cool
You got me wanting to build one :)
You should try one with a 7200RPM drive for a better time base because it spins 120 times a second, double of 60Hz making a stable clock signal.
@jse07
Actually a hard drive will fail if the interior pressure falls too low as the heads need the air to keep them "floating" on the disk.
Give a guy some Legos and he creates a skyscraper . Toss him a dead hard drive and he builds a clock with it. That right there is genius at work.
@WOUNDEDStevenJones Hmm, interesting. I hadn't noticed that till you mentioned it, but it looks like you might be right.
@mmbotti1 Backwards clock was invented in Switzerland.
@TheFisheyeProduction It's a sundial for Australia.
That is really really awesome
that's the noise it makes inside your computer... it's quieter because there are circuitboards in the way and the tower casing... as well has the HDD casing...
Very cool.
Please make a guide to making one.
