So I have managed to make a bluetooth repeater to increase my range from a greenhouse.
The only problem now is getting it powered in the field (essentially...my only option is solar).
The repeater draws between 60-100mA.
I have been browsing youtube for a bit now and can only find systems that are non-protected (simply putting a 5v regulator on a panel and connecting straight to 4AAs in series.)
Is this actually fine for long term use, or should I look at over-volt protection? Also what do I need in this case?
