I was thinking of comparing levels of technology. Here is the question. At what point is it a bad idea to use the least best to control your world? This started back when I was in DSL. The Call went like this: " My friend got a new computer, I never had one so he gave me his old one." The first warning sign should have been your friend is looking for a new home outside his house for a 25 lbs beige boat anchor. " I’m trying to get online and it’s slow, how can I make it better?" Buy a new computer.
This is a discussion of what Brian you put in control of your Maslow.
“I have a PC I put away a few years ago maybe I can repurpose it.” This statement is the equivalent of saying I want to find the stupidest person I can and have them be the bus driver on my cross country trip.
I want the smartest best qualified buss driver I can find.
It doesn’t take much on the resource level to run the software so why do I want to spend money on a current pc?
It comes down to the idea you have a driver steering, you are calling out directions, the encoders are giving feedback, 7 people are all yelling while all this is happening. The computer needs focus. If it looses focus for a fraction a second everything can be right but it might not hear an instruction or the feed back of an encoder. This will throw an error and stop everything.
My old PC is free a new one cost money. A current PC can be had for under $100. The Free solution will not cost you in ways you see at first but 8 hours into a 10 hour cut on a $300 piece of wood hurts. Chasing a problem with the motor cables because of an encoder error will take hours to find nothing. Just opening a web browser to look something up could kill a cut.
Chances are if the PC is that old it might not have updated drivers available. In it’s day Windows 7 sucked. That is users were sure Windows 98 was better and more reliable than the new Windows 7. Now people are clinging to Windows 7 as a Gem of operating systems.
If you are running Linux then you are probably aware of what your PC can do.
I’m saying that using the junker PC to run a power tool might end up being the most expensive choice you make. It will likely give you problems right after promising your 7 year old to make something special for her birthday the next day. Right after you justify the cost of your Maslow to your wife to do a house repair, it will pick the most painful time to be an issue.
Did you go out and reclaim nails and screws to build your frame? Why choose everything new until you get to the Brain for your Maslow?
This is just an observation. And that original DSL call guy, if it were a real friend they would have given you a new computer, not the one that was so bad it wasn’t usable anymore.
Use your brain when choosing a brian to drive your tool for you.
