Some of you might know, my 500gb Seagate Barracuda 7200.11 HDD died on me a few months back.
A lot of weeks ago my 80GB IDE Seagate Barracuda 7200.8 HDD also died on me,
And since then, it had been sitting in my treasure box.
I set to work on the first prototype of Lily
Some of you might know that video someone posted at CBFF about this where disks are simply given a spin and dropped off a table,
And I just developed that idea further.
So my idea was to make the disks move on their own with a proper motor.
It's a simple thing, stick a motor onto the disks,
But it's easier said than done.
So firstly, I took apart the HDDs and along with my toolset chucked it on to my cousin's bed.
- Spoiler:
Now, I did a quick scan over what I had.
To make this simple,
I'm gonna use the 3 HDD platters I have,
and slap them on to a HDD motor,
screw it up,
give it a circuit,
and voila.
Mind you it took me 6 hours to get the thing built, and I still have the testing and I also have to find some way of sticking on the circuit to the platters.
Oh and if you're pretty derp to not know what I'm building,
It's that disk thingy that Lily chucks out of her skirt.
Lets get on to the building.
First wall I came about.
The supermagnets within the HDD are almost inseparable to the pieces of metal they are stuck to, mainly because of the strong magnetic force plus the fact that seagate was stupid enough to hot glue them on.
I put it in really hot water for a few minutes to reduce the effects of the hot glue.
- Spoiler:
After drying they looked like this.
- Spoiler:
(I broke the plastic clicker on purpose.)
This made my life easier.
Out of 3 magnets(I lost one of them weeks ago)
Only one broke, and even that was just a snap in the middle, which later on became useful.
So thats done, and I'm off to srs bsns.
So I get the motor:
- Spoiler:
And I stick in the platters.
Obviously they fit nicely.
- Spoiler:
I screw on the stabilisers,
- Spoiler:
And the basic mechanism is finished.
- Spoiler:
Btw, you will/have seen a lot of pics involving my phone, which is usually because I get a txt from someone in the process.
I put the platter and motor back into the case.
Note here:
Do NOT screw the motor back on. It's a waste of time.
Use the magnets from before and put two in the gap between the platter and the motor, and the other two on the case.
Also make sure it's the Barracuda 7200.8, since it has a removable motor whereas the other one doesn't.
- Spoiler:
I had dinner after this,
And my phone ran out of battery.
- Spoiler:
Next up is soldering the circuit.
Firstly remove all the platters so that you dont have any interference when soldering.
- Spoiler:
What you'll need here is a SPDT switch(One that moves between either two circuits, and has 3 pins)
Make the positive pin (usually identifiable by how it's separated from the other two) connect to any of the outer pins on the motor, and the other two go on the remaining pins.
- Spoiler:
Solder everything, and the motor is VERY hard to solder since the pins are so small and close together
I had 7 attempts before it finally worked.
- Spoiler:
Once that's done test to make sure the circuit works.
Temporarily I used a 3V battery thing but ideally you need 12V to get the most efficient power.
- Spoiler:
Well that's what I did up to,
I'll keep working on it on saturdays, and I'll frequently update this.
Right now something went wrong and as a result it only moves for a fraction of a second before stopping.
