Hi All
I'm setting up a small display and want people's advice on where to put fuses - and what size to use.
My display will be made up as follows
250W PC power supply (contains a 6.3A fuse)
-> 3 x ~1M power leads at 12V
-> UBEC to convert 12V to 5V -> 48 x WS2811 pixels
-> 1 x 1M power lead at 12V
-> Teensy 3 microcontroller
-> 3 x data cables connecting to WS2811s
I'm using a PC supply as that's what I have handy, and UBECs (rated at 5V 5A though max draw for 48 pixels should be 2.88A) to convert the 12V to 5V to ensure a stable 5V supply (I've read the voltage on the 5V line can fluctuate and kill your pixels so this seems the safest bet)
This is going on my in the house tree so I want it as safe as possible. All equipment will be in containers of some sort so fingers cant touch connections they shouldn't.
Any help appreciated!
