Ever wondered if you can use the 5v rail on your ATX to heat the print bed while improving 12v stability?
I did and I had to know if it would work. So I did some careful maths and gave it a go. Watch this video (or the short version if your an electronics wiz, link in video description.)
I found that every ATX PSU for reprap I have seen documented online is doing it wrong!! Especially those on the wiki and forums etc!!
Do you think you know how it would go?
Post your prediction in the comments here before you watch the video to see how it worked out.
