Camera power pack (originally for a Laowa 25mm macro ring light)

thingiverse

Originally designed to power a 12V ring light for a Laowa 25mm macro lens (see my thing "Laowa 25mm macro ring light"). It allows a standard 9V PP3 battery to provide a 12V supply via a boost converter. The boost convertor used is a "TeOhk DC to DC Step Up Boost Converter MT3608". The board is approx 37.5x18mm. The 9V battery connector is a T-type (lead from top/bottom rather than side). The external power output is a 5.5MM x 2.5MM female DC panel socket. Once the battery connector and socket have been wired to the boost converter, attach a battery and measure the voltage at the socket. Turn the screw on the boost convertor to adjust the output voltage as required (in my application - to 12V). Four M2.5 countersunk screws are required to attach the lid - anything from 6mm to 10mm should be fine. An M2.5 tap is recommended for cutting threads into the holes in the base. To attach to a camera body, a 1/4-20 UNC bolt is required. I used a 1/4" long cap head bolt, and the head diameter must be less than 10mm to fit into the "chimney" in the base part.
