External Battery Mod for Action Camera Does It Non-destructively

[Facelesstech] owns an SJCAM SJ4000 motion digicam, however the inside battery used to be not purposeful. Not wishing to shop for a alternative and unwilling to hook up a clumsy USB cable to feed energy, the answer used to be to design and 3-D print an adapter to energy the digicam from a unmarried rechargeable 14500 sized battery (which is similar dimension as an AA cellular, and a just right fit for the width of the digicam.)

The adapter works through mimicking the unique battery, so the digicam by no means is aware of the adaptation. A 3-D-printed holder for the 14500 battery (which doubles as a GoPro appropriate mount) has an extension the similar dimension and form of the digicam’s unique inside battery. The difficult phase used to be interfacing to the facility connectors buried within the digicam’s battery bay. For an answer, [Facelesstech] sooner or later settled at the small connectors harvested from within a feminine header, the usage of them to connect with the small blades within the digicam. We broke open a spare feminine 0.1″ header, proven right here, to make it transparent the place those little items come from. The most effective different battery {hardware} wanted are the contacts for an AA cellular, however the ones also are simple to reap and reuse.

The GitHub repository for the challenge contains STL recordsdata in addition to the FreeCAD recordsdata for the portions. A video assessment is embedded beneath.

It’s additionally conceivable so as to add an exterior microphone enter to those cameras, however it’s significantly extra concerned than exterior energy.
