My old lady is super proud of her laser light display, so of course my dad accidentally ran over the extension cord destroying my cord and her power supply. I can mend my cord. How about this power supply-can I just attach one of my 12V power supplies to it?

Well make sure the lights have a rectifying circuit built in
(seems like they have since I can't spot diodes on that powersupply)
but CHECK!

then as long as the plug fits you'll be fine (500mW or more.. it shouldn't even mater if it's a recitified 2Amp powersupply as long as the voltage fits)

ALSO: fix the one you have...
the transformer itself hardly has any damage, it's the caps and PCB that are gone..
you can fix that with two new caps and a soldering iron and maybe some JB weld to stiffen the PCB. (you could even make a new one ;))
resistors look fine...
so that's a great opportunity to improve the desoldering/resoldering skills ;)

ha ha! great discussion. I used a 12V power supply I had laying around, I had to cut and solder the cables, and since it's outdoors I modified a plastic Folgers coffee jar to hold it all and keep it dry, works well

as for me soldering circuit boards I probably need a finer soldering iron, and a solder pump, and I dont have much experience with PCBs

worst book ever!
Anyways, welcome :D

Also: much better song on a gokart surely is "Magic carpet ride"
Still... I can't but agree with WTR...

where's the point of a DIY-whatever forum where people suggest "do not fix"
whatever it is that is to be fixed?

I do agree that you shouldn't run any improperly repaired electric appliance.
NEVER!
But replacing a broken powersupply is imho a good idea
and using the broken one as a testplatform to improve on the electronic soldering skillset
isn't a bad thing either...

Soo, IDK something escapes me, please explain!

well it rained pretty good Thursday night, in fact, here are our bikes as we came outside, I had a 30 mile ride in non stop rain to get home, the Folger's can kept the transformer dry I'm happy to report

I didn't choose the biker life landuse, the biker life chose me ;-)

Riding a bike in the rain must be one of the worst experiences you can have. I feel for you

Here is the folgers can since you're all dying to see it
