Canon EOS 350D battery adapter

thingiverse

This adapter empowers you to power your Canon EOS 350D from a standard 12 V DC power supply, capable of delivering 1 ampere or more.\r\n\r\nThe adapter is engineered to accommodate a compact DC/DC step-down regulator module sourced from Aliexpress, which can be seamlessly inserted into the battery compartment of the camera. The output voltage must be precisely calibrated to 7.4 volts.\r\n\r\nTo create the contact plates, I carefully cut out a small rectangle from a blank printed circuit board and then fashioned two distinct gaps within it using a precision cutter knife. Two cables were soldered in place between the module and the contacts, ensuring a secure connection. The entire assembly is secured with cyanocrylate adhesive and hot glue for added durability.
