Tell us about yourself!
Sorry if I insist but the image you grab shows a charging board with a protecting circuit between B- and OUT-. I use this type of board and I know how they work. If you connect the battery on OUT pads instead of B pads you bypass the protection circuit. If someone buy the same board as this one and wire it as you show the battery can be overdischarged and this is harmful for the battery AND the one who is using it.
That's a funny power supply.But you have made an error on your wiring diagram. Battery shall connect to the B+ and B- pads. Otherwise it will not charge correctly. It will not benefit of the over charge and over discharge protection circuit and may harm the battery (and maybe you)
Like it very much. I'd like to make one myself as a present but can't find a link to the free pattern.
Really nice looking project. Very elegant.But I suggest connecting earth to the steel base for safety.
