Re: Power supplying question
I have used ''wall wart'' supplies for a number of applications like that with no problems. When I retire electronic stuff that is wall wart powered I always save the power supply for this kind of project.
Re: Power supplying question
A 5V phone charger or a similar "wall wart" will work fine. Just stick to something more or less reputable, not $0.99 eBay junk.
Re: Power supplying question
I do the same, I have a collection of these "wall warts" and they are very handy around the shop
Re: Power supplying question
I think it is alot easier to use a 'proper' power supply due to the fact that a 'wall wart' is designed to plug into a power outlet.
That is a little difficult when you want to locate it inside a CNC electronics enclosure. Not impossible, just more trouble than its worth.
Just my thoughts....
