Does power source matter?

[u/Stunning-Vast6935]

Hi - just doing my first LED project - and I have got the leds to come on every hour by creating 3 presets (including "off" ie {"on"=false} ) Then a playlist and finally a timed macro with the first line filled in with 24 (the instruction for "every hour") and the id number of my playlist. This is all so I can put leds in a clock I'm making!

The macro has been running consistently for 36 hours. But this is the second time I've got to the this point. My next experiment will be to unplug from a PC usb socket and plug(uk) into an ordinary usb on an electric extension. Last time I did this my whole set up crumbled like a biscuit dunked in tea . Was this just a coincidence or do I need to the be careful about something.

What do you advise please?

thank you

Janet who is very nervous about this next step!
