I have some Raspberry Pi Controlled, 12V battery powered, time-lapse camera rigs and I need a method of swapping in new batteries without having to power down the rig.
I found a promising circuit diagram in the best answer of this thread
And here’s the relevant circuit diagram from that thread…
Can anyone confirm this as a suitable approach and suggest what parts I can purchase, ideally from Core Electronics.
I’m a novice at electronics, so please reply as if to a five year old. I would really appreciate specific part suggestions for the diodes and, as for the connectors, would I be able to get away with omething as cheap and cheerful as this…
For the connectors you can try something like this:
As far as the diodes, you just need to get some that are rated for the 12V. Check out this tutorial on analog electronics. There is a section about diodes in there that will help you out!
When it says ***
" The connector is keyed so that power cannot be reversed."*** Does that simply mean that the plugs can’t be plugged in wrongly or does it actually have an inbuilt diode?
