So, what are we going to recycle today?
Let's take a look what we have in that big box. I'm pretty sure we'll find something to start with.
Well, that's hard drive... one more... two more... plenty more; internal, external, IDE, SCSI, MFM...
Wow, that's quite a load of junk. Sadly, overall capacity of this box of HDs is much less than capacity of one HD which is humming inside my desktop today.
Let's see what we can do for those guys... this one would be good as paperweight, this one as door stopper, but this external SCSI HD looks very promising.
Let's examine it closer:
- solid metal case;
- LED at front panel;
- power connector and switch at the back;
- power supply +5V, +!2V;
- 12V fan;
That's almost finished device, it just needs new guts.
By the way, I've always wanted my own hard drive clock, and right now I have everything to build one.
That's settled. We are making hard drive clock.
Is anyone interested in joining the team?
Step 1: Another POV device
Yes, I know, I've reinvented wheel, since few projects are already built :
but in my opinion, original author of idea is Paul Gottlieb Nipkow who used spinning disk with holes to generate image:
Functionally device is quite simple and it's easy to clone it using commonly available hardware and components .
Well, main ingredients for project :
- hard drive;
- index sensor;
- power supply;
- couple of weeks without sitting in a bar, watching TV, surfing Internet ;-)
