Soldering to USB +5V

Block Image

So i have that Ali express LED Lamp projector, it has in build speakers and a LCD image unit that displays in 800x600. I thought i would be nice to upgrade it with a raspberry pi 0 that i got for birthsday. Just to play around with emulators.

I want the Pi to sit inside the projector, there is even some room left for it, i would take the HDMI cable outside just like this guy did:

And use the 5V pin of the USB (inside the projector) port to the PI

My simple question is:

Will the USB port from the projector still work (for USB sticks) when the raspberry is powered by it?

Thank you!

Didn't thought about the heat. And there's really not much free space left for proper ventilation with the Pi inside.

I wouldn't use it. The RPi 0 requires a minimum of 2.0Ah. It's had to imagine that the projector outputs more than 500mah. It'd probably run, but not very well. And certainly not when a USB flash drive is in use. You should use a separate power supply.

Last thing, if the projector is even slightly hot it will probably overheat the RPi.

Hope this helps!
