I've started a new, more specific thread, here.
I'm looking for a way to power my Pi 4B inside a 3d-printed laptop project (nothing has actually been started yet), and it would be great to hear what you think I should use and how I would wire it. Specifications:
1) I intend for all the pi's plugs to be accessible from the outside (except for GPIO and ribbon plugs), so some soldering directly to the pi is probably required. Or way better, and less permanent, I have seen some power supply converters that attach to the GPIO. (like the LiPo SHIM: but... see point 2)
- Just thinking, I might not need to access the two mini HDMI's since there's problems anyways with using the ribbon cable monitor AND the HDMI ports simultaneously, therefore leaving the possibility of keeping the power plug on the pi on the inside? Use mobile phone battery pack then?
2) (Reference to the LiPo shim) It must not cover the processor (and preferably anything else I can stick a heat sink to): I plan to use a low-profile fan on it. Circulation is already bad enough in the laptop.
3) Finally, the battery must be chargeable without taking it out of the laptop: so I might need an Arduino battery charger like this.
LIke I said, I would like to hear your opinion on the project, and even better, how I should wire it. Thanks!
