But I agree, some kind of cover from the side would be great - so at least no finger could easily get in between the motor & the belt :) So take your own safety measures when building this!
well just saying, that if a 5-10yr old having 10-15 inch long hair would come close to see "how this works" from curiosity, and if the wind blows ( or for whatever reason ) the hair would get onto any spinning part ( in between the belt in the worst case scenario ) it would take less than a second ( ~10 rolls when spinning at 600rpm ) to pull the face on to the motor / spinning disc. even if there was no friction at the motor, the inertia of a spinning disc would be quite enough power to do that.I mean, yes it's in some sort an unlikely scenario, but I'm just saying, the we all have to keep our safety measures when using power tools, and this instructable does not say otherwise ;)
Oh come on you guys, ALL power tools are dangerous, you can spin your long hair or long sleeves into a hand drill which will pull you straight toward it; you can cut your toes with a lawnmower. Any power other tool that has a powerful spinning motion is dangerous and this one is no different.Great job for the author!
Well that's a thorough explanation.I'm just talking about my personal experience.Speed: Every laptop I've upgraded to SSD has shown an incredible increase of performance like 2-3x faster startup time and apps would start almost instantly comparing to long waits before, as most of the laptops (used to) come with 4200 or 5400 rpm HDDs. Upgrading from 7200 rpm does not give such a huge difference, still, for development it's an improvement of at least 30-50% of compilation / packaging time, for example from 20 minutes down to 12 minutes for a build.Reliability: Yes I've read the specifications and working hours of SSDs and I agree that they are not designed to last more than 10 years. However, for a laptop that is carried around the house or office during meetings, airports security scanners & etc an SSD is irreplaceable. Just during the last 5 years at least 3 HDDs had failed irreversibly for me. And not the cheapest ones, but the ones you would find OEM on a Lenovo Thinkpad, which are already one of the toughest laptops on Earth. I never had even similar issues with SSDs during the last 5 years I've used different kinds of them.As a side-effect, SSDs are also lighter and use less power so battery will last longer for the same tasks.For desktop PCs - where the PC cannot be physically touched ( let's say by kicking with a knee while gaming, which happened to me multiple times and HDD broke too ) that already have 7200 RPM HDDs there's not much of an improvement, apart of being quiter, lighter and less power usage.So just to make sure were comparing apples to apples and not oranges, I still believe SSD is a great way to upgrade your laptop.
No way an HDD would outlast SSD on a laptop. I've been carrying around my laptops and all HDDs would fail in a year or two due to hitting something while carrying, or accidentally turned on got scanned in the airport security, so SSD will always outlast an HDD as there are no spinning parts.
